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

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.

track 2, we have

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

∆r = 47 / π

∆r = 14.96 ft.

∆r =  15 ft

In conclusion, difference between the radii of the two circular tracks is  15ft

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.

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.

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%

Interpret the percentage as the probability of earning 3 points or more on the Algebra EOC exam:

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 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

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.

The surface area of the triangular prism is 720in²

A prism is a solid shape that is bound on all its sides by plane faces.

The surface area of a prism is expressed as

SA = 2B +ph

where p is the perimeter of the base and h is the height of the prism.

Base area = 1/2 bh

= 1/2 × 24 × 5

= 12 × 5

= 60 in²

Perimeter of the base = 24 +13 +13

= 50 in²

the height of the prism = 12 in

therefore SA = 2 × 60+ 12 × 50

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.

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.

Candace is flipping the coin 5 times.

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

A graph of the axis of symmetry and the vertex for this function is shown below.

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.

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.

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
