3. consider the following box plot.
(a) find the interquartile range.
(b) what percent of values is included in the interquartile range?
Answers
Considering the following box plot, The interquartile range is a measure of the spread of the middle 50% of the data.
The interquartile range (IQR) is a measure of statistical dispersion that represents the range between the first quartile (Q1) and the third quartile (Q3) in a dataset. It provides a measure of the spread or variability of the middle 50% of the data.
However, explain how to calculate the interquartile range and the percentage of values included in the interquartile range based on a box plot:
(a) To find the interquartile range, you need to calculate the difference between the upper quartile (Q3) and the lower quartile (Q1). In other words, IQR = Q3 - Q1. The interquartile range is a measure of the spread of the middle 50% of the data.
(b) The interquartile range includes 50% of the values in the data set. This means that the other 50% of values lie outside the interquartile range.

Round to 1 decimal place. $_____. per sleeping bag What is the weekly fixed cost of producing sleeping bags? Round to the nearest integer $_____.
Answers
The linear regression model for the weekly cost data is given by C(z) = ma + k, where z is the independent variable representing the weekly demand.
The values of m and k are determined through the regression analysis. Using this model, we can estimate the total weekly cost for a given weekly demand and calculate the per unit variable cost and weekly fixed cost.To find the linear regression model, we need to perform a regression analysis on the given weekly cost data. This analysis will determine the values of m and k in the equation C(z) = ma + k, where C(z) represents the weekly cost and z represents the weekly demand.
Once the values of m and k are obtained, we can use the model to estimate the total weekly cost when the weekly demand is 210. By plugging in z = 210 into the equation C(z) = ma + k, we can calculate the total weekly cost rounded to the nearest dollar.The per unit variable cost can be determined by the value of m in the model. It represents the change in cost per unit change in demand. By rounding m to one decimal place, we can obtain the per unit variable cost rounded to one decimal place.
The weekly fixed cost can be determined by the value of k in the model. It represents the cost that does not depend on the weekly demand. By rounding k to the nearest integer, we can obtain the weekly fixed cost rounded to the nearest dollar.Overall, by applying the linear regression model to the given data, we can estimate the total weekly cost, calculate the per unit variable cost, and determine the weekly fixed cost of producing sleeping bags.

what is the probability of being served immediately in a three-server model?
Answers
The probability of being served immediately in a three-server model is 0.2143 or approximately 21.43%.
Consider that the arrivals follow a Poisson distribution and the service times follow an exponential distribution, the probability of being served immediately in a three-server model can be calculated using the Erlang-C formula.
The Erlang-C formula is given by:
\(P0 = 1/[1 + (A1/A)^1 + (A2/(A*A1))^2/2 + (A3/(A*A1*A2))^3/3! + ... + (Ak/(A*A1*...*Ak-1))^k/k! + ...]\)
A = total traffic intensity for the system
The traffic intensity for each server is given by:
\(Ak = (A^k/k!) * P0\)
Where k = number of servers.
LEt A = λ/3μ
where 3 is the number of servers.
Using these formulas,
\(P0 = 1/[1 + ((λ/3μ)/1)^1 + ((λ/3μ)/(λ/3μ))^2/2 + ((λ/3μ)/(λ/3μ)^2)^3/3!]\)
Simplifying the expression, we get:
\(P0 = 1/[1 + 1/3 + (1/9)(1/3)^2 + (1/27)(1/3)^3]\)
P0 = 0.2143
Therefore, the probability of being served immediately in a three-server model is 0.2143

The physical plant at the main campus of a large state university receives daily requests to replace fluorescent light bulbs. The distribution of the number of daily requests is bell-shaped and has a mean of 64 and a standard deviation of 5. What is the approximate percentage of lightbulb replacement requests numbering between 49 and 64?
Answers
Approximately 34.13% of lightbulb replacement requests fall between 49 and 64.
To determine the approximate percentage of lightbulb replacement requests between 49 and 64, we can utilize the properties of the normal distribution. Since the distribution is bell-shaped and follows a normal distribution, we can use the empirical rule (also known as the 68-95-99.7 rule) to estimate the percentage.
According to the empirical rule, approximately 68% of the data falls within one standard deviation of the mean. In this case, the range between 49 and 64 is within one standard deviation of the mean (64). However, since the data is not centered perfectly at the mean, we need to calculate the z-scores for both values to determine the precise percentage.
To calculate the z-scores, we use the formula z = (x - μ) / σ, where x is the value, μ is the mean, and σ is the standard deviation.
For 49:
z = (49 - 64) / 5 = -3
For 64:
z = (64 - 64) / 5 = 0
Using a standard normal distribution table or a calculator, we can find the percentage between -3 and 0, which corresponds to approximately 34.13%. Therefore, approximately 34.13% of lightbulb replacement requests fall between 49 and 64.

Solve for x is all related to finding the value of x in an equation of one variable that is x or with different variables like finding x in terms of y. When we find the value of x and substitute it in the equation, we should get L.H.S = R.H.S.
What Does Solve for x Mean?
Solve for x means finding the value of x for which the equation holds true. i.e when we find the value of x and substitute in the equation, we should get L.H.S = R.H.S
If I ask you to solve the equation 'x + 1 = 2' that would mean finding some value for x that satisfies the equation.
Do you think x = 1 is the solution to this equation? Substitute it in the equation and see.
1 + 1 = 2
2 = 2
L.H.S = R.H.S
That’s what solving for x is all about.
How Do You Solve for x?
To solve for x, bring the variable to one side, and bring all the remaining values to the other side by applying arithmetic operations on both sides of the equation. Simplify the values to find the result.
Let’s start with a simple equation as, x + 2 = 7
How do you get x by itself?
Subtract 2 from both sides
⇒ x + 2 - 2 = 7 - 2
⇒ x = 5
Now, check the answer, x = 5 by substituting it back into the equation. We get 5 + 2= 7.
L.H.S = R.H.S

Answers
1. graph{-x^2 [-10, 10, -5, 5]}
2. graph{-x^2+3 [-10, 10, -5, 5]}
3. The graph of the given function y = 3 - x², not by plotting points but by starting with the graph of a standard function and applying transformations, is as shown above.
Given function:
y = 3 - x²
The graph of this function can be obtained by starting with the graph of the standard function y = x² and applying some transformations such as reflection, translation, or stretching.
Here, we will use the standard function y = x² to sketch the graph of the given function and then apply the required transformations.
The standard function y = x² looks like this:
graph{x^2 [-10, 10, -5, 5]}
Now, let's apply the required transformations to this standard function in order to sketch the graph of the given function
y = 3 - x².1.
First, we reflect the standard function y = x² about the x-axis to obtain the function y = -x².
This reflection is equivalent to multiplying the function by
1. The graph of y = -x² looks like this:
graph{-x^2 [-10, 10, -5, 5]}
2. Next, we translate the graph of y = -x² three units upwards to obtain the graph of
y = -x² + 3.
This translation is equivalent to adding 3 to the function.
The graph of y = -x² + 3 looks like this:
graph{-x^2+3 [-10, 10, -5, 5]}
3. Finally, we reflect the graph of
y = -x² + 3
about the y-axis to obtain the graph of
y = x² - 3. This reflection is equivalent to multiplying the function by -1.
The graph of
y = x² - 3
looks like this:
graph{x^2-3 [-10, 10, -5, 5]}
Hence, the graph of the given function y = 3 - x², not by plotting points but by starting with the graph of a standard function and applying transformations, is as shown above.

Two metal cubes each half an edge length of 4 cm. They are melted and re-cast into a square pyramid with the height of 5 cm. Find the area of the base of the pyramid
Answers
The area of the base of the square pyramid will be 48 cm².
What exactly is square pyramid?A square pyramid is a three-dimensional geometric shape that has a square base and four triangular faces that meet at a common vertex (apex). The base of the pyramid is a square, and the four triangular faces are identical isosceles triangles.
The height of a square pyramid is the perpendicular distance from the base to the apex. The slant height of a square pyramid is the distance from the apex to the midpoint of an edge of the base. The slant height is also the height of each of the four triangular faces.
\(Volume = (1/3) \times (Area of base) \times (Height)\)
where the area of the base is the area of the square and the height is the perpendicular distance from the base to the apex.
Now,
The volume of the two metal cubes can be calculated as follows:
Volume of one cube = (1/2 x 4 cm)³ = 8 cm³
Volume of two cubes = 2 x 8 cm³ = 16 cm³
Since the metal is melted and re-cast into a square pyramid, the volume of the pyramid must be equal to the volume of the two cubes:
Volume of pyramid = 16 cm³
\(Volume = (1/3) \times (Area of base) \times (Height)\)
We know the height of the pyramid is 5 cm, so we can rearrange the formula to solve for the area of the base:
Area of base = 3 x (Volume of pyramid) / (Height)
Area of base = 3 x (16 cm³) / (5 cm)
Area of base = 48 cm²
Therefore,
the area of the base of the pyramid is 48 cm².

A rectangle has an area of 370.8 square millimeters and a height of 20.6 millimeters. What is the length of the base?
Answers
The length of the base of the rectangle is approximately 18 millimeters.
To find the length of the base of the rectangle, we can use the formula for the area of a rectangle: A = bh, where A is the area, b is the length of the base, and h is the height.
We are given that the area of the rectangle is 370.8 square millimeters and the height is 20.6 millimeters. Substituting these values into the formula, we get:
370.8 = b(20.6)
To solve for b, we can divide both sides of the equation by 20.6:
b = 370.8/20.6
b ≈ 18
Therefore, the length of the base of the rectangle is approximately 18 millimeters.
It's important to note that the units of the answer are millimeters, which is consistent with the units of the given height and area. Additionally, we rounded the answer to the nearest millimeter since the height and area were given to only one decimal place.
