Part C: Interpret the meaning of the residual from part B. (3 points)
An equation for the line of best fit for a men's height, y, based on her shoe size, x is; y = 0.25x + 66.6
What is a line of best fit?A line of best fit can be defined as a statistical (analytical) tool that is used in conjunction with a scatter plot, in order to determine whether or not there's any association (correlation) between a data.
In this scenario, the men's shoe size would be plotted on the x-axis of the scatter plot while her height would be plotted on the y-axis.
By critically observing the scatter plot (see attachment) which models the data, we can reasonably deduce that an equation for the line of best fit is given by:
y = 0.25x + 66.6

c. When x increases by one unit from left to right, we have that:
f(x) is multiplied by 4.g(x) is increased by 1.d. The functions are equal for a value between 1 and 2, as at x = 1 g(x) is greater while at x = 2 f(x) is greater.
Exponential and linear functionsThe difference between exponential and linear functions is in the rate of change, as:
Linear functions change by a constant amount when x changes by 1.Exponential functions change by a common ratio when x changes by 1.Hence the functions are classified as follows:
f(x) exponential: when x increases by 1, y is multiplied by 4.g(x) linear: when x increases by 1, y increases by 1.We have one exponential and one linear function, so it is quite difficult to solve an equation to verify where they are equal. We have that:
At x = 1, g(x) > f(x).At x = 2, f(x) > g(x).This means that at one point between x = 1 and x = 2, they intersected, that is, they had the same function values.

Answer:
769 and 858
Step-by-step explanation:
Every hour, the distance between the two planes increases by 2x + 89

4x = 3076
x = 769
a farmer needs to enclose three sides of a meadow with a fence (the fourth side is a cliff wall). the farmer has 34 feet of fence and wants the meadow to have an area of 140 sq-feet. what should the dimensions of the meadow be? (for the purpose of this problem, the width will be the smaller dimension (needing two sides); the length with be the longer dimension (needing one side). additionally, the length should be as long as possible.)
The dimensions are Width = 7 feets ; length = 20 feets
As given,
Meadow area is 140 square feet.
Height = W (smaller dimension and 2 sides)
Height = L (longer dimension and 1 side)
Fence yards equal 34 feet;
Hence,
L + W = 34
L + 2W = 34
L = 34 - 2W - - - (1)
Recall:
Area = L * W = 140
Substitute value of L
140 = (34 - 2W) * W
140 = 34W - 2W²
2W² - 34W + 140 = 0
W² - 17W + 70 = 0
W² - 10W - 7W + 70 = 0
W(W - 10) - 7(W - 10) = 0
(W - 10) = 0 or (W - 7) =0
W = 10 or W = 7
We choose the shorter width because length should be as long as possible:
W = 7
L + 2W = 34
L = 30 - 14
L = 20 feets
Therefore, The measurements are 7 feet wide and 20 feet long.

Make 'r' as the subject of the formula
m (n + r) = 5p
The equation written when r is the subject is:
[tex]\displaystyle{r=\dfrac{5p}{m}-n}[/tex]
To make the term r as the subject of equation means to isolate r-term. In order to do that, we will apply properties of equality.
What are Properties of Equality?Properties of equality are properties regarding equations/equality where states that when either sides are done by something (addition, subtraction, multiplication, division, etc.) then the other sides will also act the same as the acted side.
Example
Suppose we are given an equation of x = y. In this case, x and y are equal to each other. If x = 1 then y = 1. If we decide to add +2 to x we’d have to add it to y too so the result will be x + 2 = y + 2.
Same also applies to other equations!
SolutionIsolating r-term, first, we will apply division property where we divide both sides by m-term:
[tex]\displaystyle{\dfrac{m(n+r)}{m}=\dfrac{5p}{m}}\\\\\displaystyle{n+r=\dfrac{5p}{m}}[/tex]
Next, we use subtraction property to subtract both sides by n:
[tex]\displaystyle{n+r-n=\dfrac{5p}{m}-n}\\\\\displaystyle{r=\dfrac{5p}{m}-n}[/tex]

39,916,800 color combinations are possible
Here, we want to get the possible number of color combinations possible.
Since any number of colors can be chosen, there are no restrictions here
That means the number of possible color combinations will be;
11! = 11 * 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 = 39,916,800 color combinations
The equation for line s can be written as x - y = -2. Line t is perpendicular to lines and passes through (-4, 1). What is the equation of line t?
=========================================================
Explanation:
Anything perpendicular to Ax+By = C is of the form Bx-Ay = D
The given equation is x-y = -2 showing that A = 1, B = -1 and C = -2.
So Bx-Ay = D will update to -x-y = D
Plug in the coordinates of (-4,1) to find D.
-x-y = D
D = -x-y
D = -(-4)-1
D = 4-1
D = 3
We go from -x-y = D to -x - y = 3
Then multiply both sides by -1 to end up with x + y = -3

study was made of seat belt use among children who were involved in car crashes that caused them to be hospitalized. it was found that children not wearing any restraints had hospital stays with a mean of 7.37 days and a standard deviation of 3 days with an approximately normal distribution. (a) find the probability that their hospital stay is from 5 to 6 days, rounded to five decimal places. (b) find the probability that their hospital stay is greater than 6 days, rounded to five decimal places.
The probability that their hospital stay is greater than 6 days is equal to 0.67724 and the probability that their hospital stay is from 5 to 6 days is equal to 0.108
Mean (μ) = 7.37
Standard deviation (σ) = 3
we need to calculate probability that their hospital stay is from 5 to 6 days i.e.
⇒ P(5 < X < 6) = P(X < 6)-P(X < 5)
Here we will use standard normal distribution where,
Z-score = (X -μ )/ σ = (6 - 7.37)/3 = -0.46
Z-score = (5 - 7.37)/3 = -0.79
from Z table we found p-value
⇒P(5<X<6) = P(X<6) - P(X<5) = 0.32276 - 0.21476 = 0.108
So there is 0.108 probability that their hospital stay is from 5 to 6 days.
we need to calculate probability that their hospital stay is greater than 6 days i.e.
We get: P(X > 6) = 1 − P(X < 6)
Here we will use standard normal distribution where,
Z-score = (X - μ)/σ = (6 - 7.37)/3 = -0.46
from Z table we found p-value
P(X > 6) = 1 - P(X<6) = 1 - 0.32276 = 0.67724
So there is 0.67724 probability that their hospital stay is greater than 6 days.

You invest $8,000 in 3 investment accounts. The accounts are: paper, metal and glass. Paper returns 2% income, metal returns 4% income, and glass returns 5% income. The amount invested in the glass account was double the amount invested in the metal account. The yield was a total of $280 at the end of one year. How much was invested in each account?
The following investments were done:
Metal account: $ 1,500Glass account: $ 3,000Paper account: $ 3,500How much money has a person invested in three accounts?
In this problem we must determine how much money from a $ 8,000 investment has been deposited in each account based on overall yield after a period of one year. In accordance with the statement, the person deposited the following quantities in each account:
Metal: x
Glass: 2 · x
Paper: 8,000 - 3 · x
And the yield function is equal to:
280 = x · (4 / 100) + 2 · x · (5 / 100) + (8,000 - 3 · x) · (2 / 100)
280 = 0.04 · x + 0.1 · x + 160 - 0.06 · x
