When creating lines of best fit, do you believe that estimation by inspection of the equation is best or do you think it should be determined exactly? In what situations would it be best to use one over the other?




Your response should be 3-5 sentences long and show that you’ve thought about the topic/question at hand

Answers

Answer 1

In general, it is best to determine the equation of the line of best fit exactly rather than relying on estimation by inspection. This is because an exact equation allows for more precise predictions and calculations.

Estimation by inspection can be useful in situations where the data is relatively simple and a rough estimate is sufficient. However, in more complex datasets, it is important to use statistical methods to determine the line of best fit accurately.

It is also worth noting that in some cases, different methods of determining the line of best fit may be appropriate depending on the specific goals of the analysis.

For example, in some cases, it may be more important to prioritize the accuracy of the slope of the line over the accuracy of the intercept. In such cases, certain methods, such as minimizing the sum of the squares of the vertical deviations, may be more appropriate than others.

A bag contains five red socks and eight blue socks. Lucky reaches into the bag and randomly selects two socks without replacement. What is the probability that Lucky will get different colored socks? Express your answer as a common fraction. ​ I will give brainliest if you give a full explanation, I have the answer but I need to know HOW to solve the problem!!!

Answers

The probability that Lucky will get different colored socks is 1/6 or 1 out of 6.

To solve this problem, we can use the concept of probability and combinations.

Step 1: Determine the total number of possible outcomes.

When Lucky selects two socks without replacement, there are a total of 13 socks in the bag (5 red + 8 blue). So, the total number of possible outcomes is given by selecting 2 socks out of 13, which is represented as C(13, 2) or 13 choose 2.

C(13, 2) = (13!)/(2!(13-2)!) = (13 * 12)/(2 * 1) = 78

Step 2: Determine the number of favorable outcomes.

For Lucky to get different colored socks, there are two cases to consider: selecting a red sock first and a blue sock second, or selecting a blue sock first and a red sock second.

Case 1: Red sock first, then blue sock:

The number of ways to select one red sock out of five is C(5, 1) = 5. After selecting one red sock, there are eight blue socks remaining, and Lucky needs to select one blue sock out of eight, which is C(8, 1) = 8.

Case 2: Blue sock first, then red sock:

The number of ways to select one blue sock out of eight is C(8, 1) = 8. After selecting one blue sock, there are five red socks remaining, and Lucky needs to select one red sock out of five, which is C(5, 1) = 5.

So, the total number of favorable outcomes is 5 + 8 = 13.

Step 3: Calculate the probability.

The probability of getting different colored socks is the ratio of the number of favorable outcomes to the total number of possible outcomes:

P(Different Colored Socks) = Number of Favorable Outcomes / Total Number of Possible Outcomes

= 13 / 78

= 1/6

Therefore, the probability that Lucky will get different colored socks is 1/6 or 1 out of 6.

From the histogram, we see that the frequency for the bin that ranges from 42 to 45mm is 4 and we have  a total of 33 eggwe use this values and calculate the percentage of eggs between 42 and 45mm is 48.48%.

part b.

we have an  estimation  that the median of the width is 48mm and the median of the length is around 60mm.

part c.

Also from the histogram, we notice  that the smallest value is around 36mm and the largest value is around 66mm, hence the width of grade A chicken eggs has a range of about 24mm.

In a histogram, the range is the width that the bars cover along the x-axis and these are approximate values because histograms display bin values rather than raw data values.

The equations to find the amount of red fabric Moses has are X = x + 2 and X + 222 = 1/3x + 223. These equations are obtained by using x as the amount of blue fabric and setting up equations based on the given information. So, the correct answer is A) and E).

There are two equations that can be used to find the amount of red fabric Moses has

X = x + 2, This equation represents the fact that Moses bought 2 more yards of red fabric than he originally had of blue fabric. So, the amount of red fabric (X) is equal to the amount of blue fabric (x) plus 2.

X + 222 = 1/3x + 223, This equation represents the fact that after buying 2 more yards of red fabric, Moses has equal amounts of red and blue fabric.

So, the amount of red fabric (X) plus 222 (the additional 2 yards he bought) is equal to one-third of the amount of blue fabric (1/3x) plus 223 (the original 2 yards of red fabric he had).

Therefore, the equations that could be used to find the amount of red fabric Moses has are A) and E).

John has $23. 65 spend on a book and magazines. The book costs $5. 95z the magazines cost $2. 95 each. A) write an equation that models the number of magazines that John can afford. B) solve the equation

Answers

John can afford approximately 6 magazines.

A) To write an equation that models the number of magazines John can afford, let's denote the number of magazines as 'm'. Since each magazine costs $2.95 and John has a total of $23.65 to spend, the equation can be expressed as:

2.95m + 5.95 = 23.65

B) To solve the equation, we can isolate the variable 'm' by subtracting 5.95 from both sides:

2.95m = 23.65 - 5.95

2.95m = 17.70

Then, divide both sides by 2.95:

m = 17.70 / 2.95

m ≈ 6

Therefore, John can afford approximately 6 magazines.

In conclusion, the equation 2.95m + 5.95 = 23.65 models the number of magazines John can afford, and by solving it, we find that he can purchase approximately 6 magazines with the given amount of money.

The Louvre is an art museum in Paris. A glass square base pyramid sits in front of the entrance to the museum. If the pyramid is 35 meters wide at the base and 20. 6 meters tall, what was the minimum amount of glass needed to construct the pyramid?

Answers

The minimum amount of glass needed to construct the Louvre pyramid is approximately 3133 square meters.

What is the minimum amount of glass needed to construct the glass pyramid in front of the Louvre museum in Paris, if the pyramid is 35 meters wide at the base and 20.6 meters tall?

The surface area of a square base pyramid can be calculated by adding the area of the base to the sum of the areas of the four triangular faces.

The area of the square base is simply the width of the base squared:

Area_base = (35 m)^2 = 1225 square meters

The area of each triangular face can be calculated using the formula:

Area_triangle = (1/2) * base * height

For the Louvre pyramid, the base of each triangular face is equal to the width of the base of the pyramid, which is 35 meters. The height of each triangular face can be found using the Pythagorean theorem:

[tex]height^2 = (1/2 * width)^2 + height^2[/tex]

[tex]height = sqrt((1/2 * 35 m)^2 + (20.6 m)^2)[/tex]

height = 29.2 m

Therefore, the area of each triangular face is:

Area_triangle = (1/2) * (35 m) * (29.2 m) = 508.5 square meters

The total surface area of the pyramid is:

Surface_area = Area_base + 4 * Area_triangle

Surface_area = 1225 + 4 * 508.5

Surface_area = 3133 square meters

Since the pyramid is made of glass, we need to calculate the minimum amount of glass needed to construct it. Assuming the glass is thin and flat, we can simply use the surface area of the pyramid to estimate the amount of glass needed.

Assets        -               Amount

Checking amount -  $14,532

Retirement savings- $43,675

Car                          - $12,225

Therefore total assets equal to: $70,432

Now, for liabilities

Liabilities            -       Amount

Student loan             $1,225

Credit card debt       $3,876

Home loan balance  $65,225

Therefore total liabilities equals to: $70,326

The net worth can be find out by subtracting the total liabilities from the total assets:

Hence Net worth = Total assets- Total liabilities

                             = $70,432- $70,326

Find the area of the region bounded by the
curves:
y = 10 - x^2

The area of the region bounded by the curves is 4/3 square units.

To find the area of the region bounded by the curves y = 10 - [tex]x^2[/tex] and y = [tex]x^2[/tex] + 8, we need to find the points of intersection between the two curves.
Setting the two equations equal to each other, we have:
10 - [tex]x^2[/tex] = [tex]x^2[/tex] + 8
Simplifying, we get:
[tex]2x^2[/tex] = 2
[tex]x^2[/tex] = 1
x = ±1
Substituting x = 1 into either equation gives us:
y = 10 - [tex]1^2[/tex] = 9
And substituting x = -1 gives us:
y = 10 - [tex](-1)^2[/tex] = 10
So the two curves intersect at the points (1, 9) and (-1, 10).
To find the area of the region bounded by the curves, we need to integrate the difference between the two equations with respect to x, from x = -1 to x = 1:
∫[10 - [tex]x^2[/tex]] - [[tex]x^2[/tex] + 8] dx, from x = -1 to x = 1
= ∫(2 - 2[tex]x^2[/tex]) dx, from x = -1 to x = 1
= [2x - (2/3)[tex]x^3[/tex]] from x = -1 to x = 1
= 4/3
So

The area of the region bounded by the curves y = 10 - [tex]x^2[/tex] and y = [tex]x^2[/tex] + 8 is 4/3 square units.

(1 point) Find the maximal area of a right triangle with hypotenuse of length 3.

Answers

The maximal area of a right triangle with hypotenuse of length 3 is 0.

How to calculate the maximal area?

Let's call the legs of the right triangle a and b.

Since the hypotenuse has length 3, we know that a² + b² = 3² = 9

The area of the triangle is given by A = 1/2 ab.

We want to maximize A subject to the constraint a² + b²= 9.

One way to do this is to use the method of Lagrange multipliers.

We want to maximize the function f(a, b) = 1/2 ab subject to the constraint g(a, b) = a²+ b² - 9= 0. The Lagrangian is then:

L(a, b, λ) = f(a, b) - λg(a, b) = 1/2 ab - λ(a² + b² - 9)

To find the maximum, we need to solve the system of equations:

∂L/∂a = 0∂L/∂b = 0∂L/∂λ = 0

Taking the partial derivatives and setting them equal to zero, we get:

b/2 - 2λa = 0a/2 - 2λb = 0a² + b²- 9 = 0

Solving the first two equations for a and b in terms of λ and plugging them into the third equation,

we get:

4λ² + 1 = 0

Then from the constraint a² + b² = 9, we have a = ±3.

The area of the triangle in this case is A = 1/2 ab = 0.

Therefore, the maximal area of a right triangle with hypotenuse of length 3 is 0, and it is achieved when one of the legs has length 0.

Dina has a mass of 50 kilograms and is waiting at the top of a ski slope that’s 5 meters high. the maximum kinetic energy she can reach when she skis to the bottom of the slope is joules. use pe = m × g × h and g = 9.8 m/s2. ignore air resistance and friction.

Answers

Dina can reach a maximum kinetic energy of 2450 Joules when she skis to the bottom of the slope.

How much kinetic energy can Dina reach?

Potential energy (PE) = m x g x h

where m = mass, g = acceleration due to gravity, and h = height

Here, Dina's mass (m) = 50 kg, height (h) = 5 m, and acceleration due to gravity (g) = 9.8 m/s².

So, PE = 50 x 9.8 x 5

PE = 2450 Joules

When Dina skis down the slope, all of her potential energy will be converted into kinetic energy (KE) at the bottom of the slope, neglecting any losses due to friction and air resistance.

Thus, the maximum kinetic energy (KE) Dina can reach at the bottom of the slope is also 2450 Joules.

The maximum kinetic energy she can reach when she skis to the bottom of the slope is 2452 joules

To find the maximum kinetic energy that Dina can reach when she skis to the bottom of the slope, we need to use the principle of conservation of energy, which states that the total energy of a system remains constant.

At the top of the slope, Dina has potential energy due to her position relative to the ground. This potential energy is given by:

PE = m × g × h

where m is Dina's mass (50 kg), g is the acceleration due to gravity (9.8 m/s^2), and h is the height of the slope (5 m).

PE = 50 kg × 9.8 m/s^2 × 5 m = 2450 J

When Dina skis to the bottom of the slope, all of her potential energy is converted into kinetic energy, which is given by:

KE = 1/2 × m × v^2

where v is her velocity at the bottom of the slope.

To find the maximum velocity, we can use the fact that the total energy of the system remains constant:

PE = KE

2450 J = 1/2 × 50 kg × v^2

v^2 = 98 m^2/s^2

v = sqrt(98) = 9.90 m/s

Finally, we can substitute this velocity into the kinetic energy equation to find the maximum kinetic energy that Dina can reach:

KE = 1/2 × 50 kg × (9.90 m/s)^2 = 2452 J

Therefore, Dina can reach a maximum kinetic energy of 2452 Joules when she skis to the bottom of the slope.

Suppose that you measure the flow rate of blood in an artery. You find that your measurements are well-fit be the equation dᏙ /dt =10 - 2 cos(120t)


in units of milliliters per second.


a) What volume of blood flows through the artery in 10 seconds? (include units)


b) What volume of blood flows through the artery in one minute? (include units)

Answers

The volume of blood flow through the artery in one minute is 600 milliliters.

We can integrate the given equation to get the volume of blood flow.

a) Integrating both sides of the equation with respect to time from 0 to 10 seconds, we get:

∫dᏙ = ∫(10 - 2cos(120t)) dt

ΔᏙ = [10t - (1/60)sin(120t)] from 0 to 10

ΔᏙ = [(10 x 10) - (1/60)sin(1200)] - [(10 x 0) - (1/60)sin(0)]

ΔᏙ ≈ 100 - 0

So, the volume of blood flow through the artery in 10 seconds is 100 milliliters.

b) To find the volume of blood flow through the artery in one minute, we need to integrate the given equation from 0 to 60 seconds:

∫dᏙ = ∫(10 - 2cos(120t)) dt

ΔᏙ = [10t - (1/60)sin(120t)] from 0 to 60

ΔᏙ = [(10 x 60) - (1/60)sin(7200)] - [(10 x 0) - (1/60)sin(0)]

ΔᏙ ≈ 600 - 0

So, the volume of blood flow through the artery in one minute is 600 milliliters.

area of circles - item 34972
the diameter of a quarter is about 1 in.
you trace around the edge of the quarter on a sheet of paper.
what is the area of the circle on the paper?
use 3. 14 as an approximation for a round your answer to the nearest tenth,

Answers

the area of the circle on the paper is approximately 0.8 square inches.

To find the area of the circle traced on the paper, we'll use the formula for the area of a circle, which is A = πr², where A is the area, π is approximately 3.14, and r is the radius.

The diameter of the quarter is about 1 inch, so the radius is half of that, which is 0.5 inches. Now, plug the radius into the formula:

A = 3.14 × (0.5)²
A = 3.14 × 0.25
A ≈ 0.785

Therefore, the area of the circle on the paper is approximately 0.8 square inches when rounded to the nearest tenth.

Step-by-step explanation:

A video game player is creating a user identification to play a game. The identification must consist of one vowel (A, E, I, O, U) followed by any one number (2, 4, 6, 8). What is the probability that the user identification will contain both an E and an 8?

Answers

The probability that the user identification will contain both an E and an 8 is 1/20, or 5%.

To determine the probability of a user identification containing both an E and an 8, we will break down the problem step-by-step.
1. Identify the total number of possibilities:
There are 5 vowels (A, E, I, O, U) and 4 even numbers (2, 4, 6, 8). To calculate the total number of possible user identifications, multiply the number of vowels by the number of even numbers:
Total possibilities = 5 vowels × 4 even numbers = 20 combinations
2. Determine the desired outcome:
In this case, we are interested in the combination that has an E followed by an 8. There is only one such combination: E8.
3. Calculate the probability:
To find the probability of the desired outcome, divide the number of desired outcomes by the total number of possible outcomes:
Probability = Desired outcomes / Total possibilities
Probability = 1 / 20
