Answers

Answer 1

A. The missing value for P(X = 1) is 0.20.

B.  The value of P(X ≤ 2) is 0.85.

C.  The value of P(X > 2) is 0.15.

D. The probability of "At least 2" is equivalent to P(X >= 2), which is 0.75.

In probability theory, a probability distribution is a function that assigns probabilities to each possible value of a random variable.

In this Problem, we have a probability distribution for the score on a quiz, with X being the random variable and the table providing the probability of each possible score. In this answer, we will use the given probability distribution to answer the questions posed.

A) Find the missing value for P(X = 1) in the probability distribution.

To find the missing value for P(X = 1), we need to use the fact that the sum of the probabilities for all possible values of X must be equal to 1. Therefore, we can set up an equation:

P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) = 1

Substituting in the given probabilities, we get:

0.05 + P(X = 1) + 0.60 + 0.15 = 1

Simplifying, we get:

P(X = 1) = 0.20

Therefore, the missing value for P(X = 1) is 0.20.

B) P(X ≤ 2) =

To find P(X ≤ 2), we need to add up the probabilities of X being less than or equal to 2. This is equivalent to:

P(X ≤ 2) = P(X = 0) + P(X = 1) + P(X = 2)

Substituting in the given probabilities, we get:

P(X ≤ 2) = 0.05 + 0.20 + 0.60 = 0.85

Therefore, P(X ≤ 2) is 0.85.

C) P(X > 2) =

To find P(X > 2), we need to add up the probabilities of X being greater than 2. This is equivalent to:

P(X > 2) = P(X = 3)

Substituting in the given probabilities, we get:

P(X > 2) = 0.15

Therefore, P(X > 2) is 0.15.

D) The probability of "At least 2" is equivalent to P(X >= 2)

To find the probability of "At least 2," we need to add up the probabilities of X being greater than or equal to 2. This is equivalent to:

P(X ≥ 2) = P(X = 2) + P(X = 3)

Substituting in the given probabilities, we get:

P(X ≥ 2) = 0.60 + 0.15 = 0.75

Therefore, the probability of "At least 2" is equivalent to P(X ≥ 2), which is 0.75.

The basketball coach can order approximately 34 shooting shirts for $300.

To determine the number of shooting shirts the basketball coach can order for $300, we need to solve the equation C = 0.2x^2 + 1.6x + 15, where C represents the cost and x represents the number of shooting shirts.

The equation is given as C = 0.2x^2 + 1.6x + 15.

To find the number of shooting shirts for $300, we set the cost C equal to 300 and solve for x:

0.2x^2 + 1.6x + 15 = 300

0.2x^2 + 1.6x + 15 - 300 = 0

0.2x^2 + 1.6x - 285 = 0

Now we can solve this quadratic equation using factoring, completing the square, or the quadratic formula. Let's use the quadratic formula:

x = (-b ± sqrt(b^2 - 4ac)) / (2a)

For this equation, a = 0.2, b = 1.6, and c = -285. Plugging in these values into the quadratic formula:

x = (-1.6 ± sqrt(1.6^2 - 4 * 0.2 * -285)) / (2 * 0.2)

Simplifying the equation further:

x = (-1.6 ± sqrt(2.56 + 228)) / 0.4

x = (-1.6 ± sqrt(230.56)) / 0.4

x = (-1.6 ± 15.18) / 0.4

Now we have two solutions:

x1 = (-1.6 + 15.18) / 0.4 = 33.95

x2 = (-1.6 - 15.18) / 0.4 = -44.95

Since the number of shooting shirts cannot be negative, we discard the negative solution.

Therefore, the basketball coach can order approximately 34 shooting shirts for $300.

A movie ticket is 12.00 plus an 8.5 sales tax how much will one ticket movie cost

Answers

The cost of one movie ticket, including sales tax, is $13.02

The cost of the movie ticket is $12.00, and the sales tax rate is 8.5%. To find the amount of sales tax on the ticket, we can multiply the ticket price by the tax rate:

Sales tax = 12.00 * 0.085

= 1.02

So the sales tax on the ticket is $1.02.

To find the total cost of the ticket, we add the ticket price to the sales tax:

Total cost = 12.00 + 1.02

= 13.02

Therefore, the cost of one movie ticket, including sales tax, is $13.02.

Answers

Answer:

y = -6/7x - 3/7 or 7y = -6x - 3

Step-by-step explanation:

I'm guessing you mean line c: y = -6/7x - 1

Parallel lines have same slope => line d will have slope = -6/7

y = mx + b

-9 = -6/7(10) + b

-9 = -60/7 + b

A piece of equipment costs $75,000 new but depreciates 12% per year in each succeeding year . Find its value after 8 years

Answers

The equipment's value after 8 years, given its original value was $75,000 and it depreciates by 12% each year, is approximately $27,506.62.

To find the value of the equipment after 8 years, we need to calculate its value at the end of each year, taking into account the 12% depreciation per year.

At the end of year 1, the equipment will be worth 88% of its original value

Value at end of year 1 = 0.88 x $75,000 = $66,000

At the end of year 2, the equipment will be worth 88% of its value at the end of year 1

Value at end of year 2 = 0.88 x $66,000 = $58,080

We can continue this process for each year

Value at end of year 3 = 0.88 x $58,080 = $51,206.40

Value at end of year 4 = 0.88 x $51,206.40 = $45,065.91

Value at end of year 5 = 0.88 x $45,065.91 = $39,654.02

Value at end of year 6 = 0.88 x $39,654.02 = $34,991.23

Value at end of year 7 = 0.88 x $34,991.23 = $31,191.80

Value at end of year 8 = 0.88 x $31,191.80 = $27,506.62

Therefore, the value of the equipment after 8 years is $27,506.62.

Answers

The cell for women who suffer from depression and drink between 2-6 cups of caffeinated coffee per week contributes 4 to the overall chi-square test statistic.

To calculate the expected count for women who suffer from depression and drink between 2-6 cups of caffeinated coffee per week under the null hypothesis, you would first need to determine the overall proportion of women who suffer from depression and drink between 2-6 cups of caffeinated coffee per week in the sample. Let's say this proportion is 0.20.

Next, you would multiply this proportion by the total sample size to get the expected count. Let's say the total sample size is 500 women. The expected count for women who suffer from depression and drink between 2-6 cups of caffeinated coffee per week would be:

Expected count = 0.20 x 500 = 100

To calculate the contribution of the cell for women who suffer from depression and drink between 2-6 cups of caffeinated coffee per week to the chi-square test statistic, you would need to subtract the expected count from the observed count for this cell, square the difference, and divide by the expected count. Let's say the observed count for this cell is 80.

Contribution to chi-square = (80 - 100)^2 / 100 = 4

This means that the cell for women who suffer from depression and drink between 2-6 cups of caffeinated coffee per week contributes 4 to the overall chi-square test statistic.

The rule is x→y=−2x. Can you mark all the points that fit the rule on a coordinate plane?

Answers

Yes, the points that fit the rule x→y=−2x can be plotted or marked on a coordinate plane, and will form a straight line passing through the origin with a slope of -2.

The rule x→y=−2x means that for every value of x, the corresponding value of y is equal to -2 times x. To plot the points that fit this rule, we can choose some values of x, substitute them into the equation, and then plot the resulting points on the coordinate plane.

For example, if we choose x=1, then y=−2x=−2(1)=−2. So the point that fits the rule is (1, −2). Similarly, if we choose x=2, then y=−2x=−2(2)=−4. So the point that fits the rule is (2, −4).

We can continue this process for other values of x, and plot all the resulting points on the coordinate plane. The resulting graph will be a straight line that passes through the origin, with a slope of -2. This means that all the points that fit the rule will lie on this line.

The number of units that must be produced and sold in order to break even = 120

Consider equation C = 15x +300

This equation represents the​ cost, in​ dollars, of x units of a product

and equation R = 17.5x represents the​ revenue, in​ dollars, from the sale of x units.

In order to find the number of units that must be produced and sold in order to break even, consider C = R

The difference between the radii of the two circular tracks is 15ft

How do we calculate?

The total length of track 1 is 220ft, which means that the circumference of the circle is 220ft

we find the diameter of each track.

The circumference of a circle can be found  using the formula

P = πd

d = P /π

track 1, we have

d1 = P1 / π

d1 = 220 / π

d1 = 70.03 ft.

d2 = P2 / π

d2 = 126 / π

d2 = 40.11 ft.

radius of tract 1  = 35.01 ft

radius of track 2 = 20.05 ft

The difference between the two track radius is

∆r = r1 - r2

∆r = 110 / π - 63 / π

∆r = (110 - 63) / π

9. Ms. Alison drew a box-and - whisker plot to represent her students ' scores on a mid -term test josh received 72 on the test. Describe how his score compared to those of his classmates. About 25% scored higher; about 75% scored lower. Everyone scored higher. No one scored higher. About 50% scored higher, about 50% scored lower.

Answers

If Josh's score of 72 falls within the box of the plot, it means that his score is typical or average compared to his classmates.

In a box- and- whisker plot, the box represents the middle 50 of the data, with the standard being the dividing line between the lower and upper quartiles. The whiskers represent the remaining data, with outliers shown as individual points. Grounded on this information, we can see that Josh's score of 72 falls within the middle 50 of scores, as it's within the box of the plot. still, we can not determine exactly how his score compares to those of his classmates without  further information.  

Minimum score: 50

Lower quartile (Q1): 65

Median (Q2): 75

Upper quartile (Q3): 85

Maximum score: 95

Josh's score: 72

Using the steps outlined previously:

Q1 = 65, Q2 = 75, Q3 = 85

IQR = Q3 - Q1 = 85 - 65 = 20

Minimum score = 50, Maximum score = 95

Since Josh's score (72) falls within the IQR (65 ≤ 72 ≤ 85), we compare it to the median:

Josh's score is less than the median, so approximately 50% of his classmates scored higher than Josh, and approximately 50% scored lower.

what is the distinction between a positive and negative mean deviation in terms of meaning applied to the data values?

Answers

Positive mean deviation means that the data values are on average greater than the mean, while negative mean deviation means that the data values are on average lower than the mean. This provides insight into the distribution of the data and can help identify outliers or trends in the data.

Mean deviation is a measure of dispersion that indicates how much a set of data values varies from the mean value of the data set. A positive mean deviation indicates that the data values are larger than the mean value, while a negative mean deviation indicates that the data values are smaller than the mean value.

In other words, a positive mean deviation indicates that the data set tends to be higher than the average, while a negative mean deviation indicates that the data set tends to be lower than the average.

Therefore, the sign of the mean deviation reflects the direction of deviation of the data values from the mean value, whether above or below it, and it provides important information about the distribution of the data set.

How to calculate the z-score?

To calculate the z-score of each value, we will use the formula:

z = (x - mean) / standard deviation

where x is the value, mean is the mean of the data set, and standard deviation is the standard deviation of the data set.

Given the data set has a mean of 25 and a standard deviation of 5, we can calculate the z-score for each value as follows:

For x = 39:

z = (39 - 25) / 5 = 2.8

For x = 18:

z = (18 - 25) / 5 = -1.4

For x = 125:

z = (125 - 25) / 5 = 20

For x = 25:

z = (25 - 25) / 5 = 0

For x = 11:

z = (11 - 25) / 5 = -2.8

Therefore, the z-score of 39 is 2.8, the z-score of 18 is -1.4, the z-score of 125 is 20, the z-score of 25 is 0, and the z-score of 11 is -2.8.

To find the probability of scoring at least 700 points on the Algebra EOC, we calculate the z-score, which is -0.122, and then find the area under the standard normal curve using a z-table. The probability is 54.98%. Since this is higher than the significance level of 0.05, we can conclude that the student has met the requirement to earn 3 points on the EOC.

Identify the mean, standard deviation, and score needed to earn 3 points

Mean (μ) = 704.39

Standard deviation (σ) = 36.18

Score needed for 3 points = 700

Calculate the z-score for the score needed to earn 3 points

z = (score - μ) / σ

= (700 - 704.39) / 36.18

= -0.122

Look up the area to the left of the z-score in the standard normal distribution table

The area to the left of -0.122 is 0.4502.

Subtract the area found in step 3 from 1 to find the area to the right of the z-score

Area to the right = 1 - 0.4502 = 0.5498

Convert the area to the right into a percentage

Percentage = 0.5498 x 100% = 54.98%

A credit card has a 21. 99% APR, a minimum monthly payment of 3. 15%, and a current monthly statement balance of $3,651. 21. If there are $791. 25 in purchases and a payment of $210. 00 in the next month, what will be the next minimum monthly payment? Show your work

Answers

The next minimal monthly payment will be $110.54.

To calculate the next minimal monthly price, we want to follow these steps:

First, we want to calculate the interest charged at the current monthly statement stability.

To do that, we multiply the statement stability by using the monthly interest price. The monthly interest fee is the annual percentage rate (APR) divided by way of 12. consequently:

Interest charged = $3,651.21 x (21.ninety nine%/12) = $sixty seven.25

next, we upload the interest charged to the statement balance to get the new balance:

New stability = $three,651.21 + $sixty seven.25 = $three,718.46

We then subtract any payments made throughout the month. In this situation, the price was $210.00, so:

New balance after price = $three,718.46 - $210.00 = $3,508.forty six

Ultimately, we calculate the minimal monthly charge. The minimum month-to-month payment is the greater of $25 or 3.15% of the new stability. therefore:

Minimum month-to-month fee = max($25, 3.15% x $3,508.46) = $110.54

So, the next minimal monthly payment will be $110.54.

Candace is flipping a coin a certain number of times. The theoretical probability of her flipping tails on all flips is 1/32. How many times is she flipping the coin?

Answers

Candace is flipping the coin 5 times.

What is probability?

The probability of an event occurring is defined by probability. There are many instances in real life where we may need to make predictions about how something will turn out.

The theoretical probability of flipping tails on any single flip of a fair coin is 1/2, since there are two equally likely outcomes (heads or tails) on each flip.

If Candace is flipping the coin a certain number of times and the theoretical probability of flipping tails on all flips is 1/32, we can set up the equation:

[tex](1/2)^n[/tex] = 1/32

where n is the number of times Candace is flipping the coin.

We can simplify this equation by taking the logarithm of both sides:

[tex]log((1/2)^n) = log(1/32)[/tex]

Using the property of logarithms that [tex]log(a^b) = b*log(a)[/tex], we can rewrite the left-hand side as:

n*log(1/2) = log(1/32)

We can simplify the logarithms using the fact that log(1/a) = -log(a), so:

n*(-log(2)) = -log(32)

Dividing both sides by -log(2), we get:

n = -log(32) / log(2)

Using a calculator, we find:

n ≈ 5

Therefore, Candace is flipping the coin 5 times.

A particle moves with position function s=t" - 413 - 20+2 + 20t, t > 0 At what time does the particle have a velocity of 20 m/s? At what time is the acceleration 0? What is the significance of this variance?

Answers

Since t > 0, the time when the particle has a velocity of 20 m/s is approximately t ≈ 4.27 seconds.

A particle has a position function s(t) = t^3 - 4t^2 - 20t + 2 + 20t, t > 0. To find the time when the particle has a velocity of 20 m/s, we first need to find the velocity function by taking the derivative of the position function with respect to time:

v(t) = ds/dt = 3t^2 - 8t - 20.

Now set v(t) equal to 20 and solve for t:

20 = 3t^2 - 8t - 20.

40 = 3t^2 - 8t.

Now solve the quadratic equation for t:

t ≈ 4.27, -3.10.

To find the time when the acceleration is 0, we need to find the acceleration function by taking the derivative of the velocity function with respect to time:

a(t) = dv/dt = 6t - 8.

Now set a(t) equal to 0 and solve for t:

0 = 6t - 8.

t = 8/6 = 4/3.

So, the acceleration is 0 at t = 4/3 seconds.

The variance in acceleration signifies a change in the motion dynamics of the particle. When the acceleration is 0, it indicates that the particle is neither speeding up nor slowing down at that moment, resulting in a constant velocity.

Triangle A B C is shown. Side A C has a length of 27. Side C B has a length of 54.
Based on the diagram, which expresses all possible lengths of segment AB?

AB = 25
27 < AB < 81
AB = 85
AB< 27 or AB > 81

Answers

Step-by-step explanation:

Based on the diagram and the given lengths of sides AC and CB, we can use the triangle inequality theorem to determine the possible lengths of side AB.

According to the theorem, the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. Therefore:

AC + CB > AB

27 + 54 > AB

81 > AB

Also, using the same theorem, we can see that:

AB + AC > CB

AB + 27 > 54

AB > 54 - 27

AB > 27

Therefore, we have:

27 < AB < 81

So, the answer is: 27 < AB < 81

Answer:

Based on the information given, the possible lengths of segment AB can be determined using the Triangle Inequality Theorem. This theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. In this case, we can apply the theorem to sides AC and CB to find the possible range of values for side AB.

Since AC has a length of 27 and CB has a length of 54, we can write two inequalities based on the Triangle Inequality Theorem:

AB + 27 > 54 AB + 54 > 27

Solving each inequality for AB, we get:

AB > 27 AB > -27

Since the length of a side of a triangle must be positive, we can disregard the second inequality. Therefore, the possible range of values for side AB is AB > 27.

However, it’s important to note that you mentioned a diagram in your message but did not provide it. Without seeing the diagram, I cannot determine if there are any additional constraints on the length of side AB.

What is the graph of a quadratic function?

In Mathematics and Geometry, the graph of a quadratic function would always form a parabolic curve because it is a u-shaped. Based on the graph of this quadratic function, we can logically deduce that the graph is an upward parabola because the coefficient of x² is positive and the value of "a" is greater than zero (0).

Since the leading coefficient (value of a) in the given quadratic function h(x) = (x - 5)² - 7 is positive 1, we can logically deduce that the parabola would open upward and the solution would be on the x-intercepts. Also, the value of the quadratic function f(x) would be minimum at -7.

In conclusion, the turning point and vertex is given by the ordered pair (5, -7).
