A plot of residuals (vertical deviations from the regression line) shows the errors or lack of fit, so it would indicate a good fit if the residuals are small, vs. over fit if they are large. Due to age related growth short pre teen, and a plateau after age 21, I would expect a linear regression would offer estimate age 5.5 years.
Answer:
Step-by-step explanation:
Anything raise to the power zero is 1

Answer:
3 gallons
Step-by-step explanation:
Length of the rectangular wall = 23.6 feet
Width of the rectangular wall = 19.2 feet
Surface area of the wall = 23.6 × 19.2
= 453.12 square feet
∵ 200 square feet of the wall is covered by the amount of paint = 1 gallon
∴ 1 square feet of the wall will be covered by the amount of paint =
gallons
∴ 453.12 square feet will require the amount of paint = 
= 2.2656 gallons
Therefore, minimum 3 gallons will be required to paint the wall.
4 ⁽ˣ⁺⁵⁾ = 16 (x-3)
Simplify.
4x + 20 = 16x - 48
Subtract 16x from both sides, as well as subtracting 20 from both sides.
4x - 16x = -48 - 20
Add like terms.
-12x = -68
Divide both sides by -12
x = 5 2/3

<u>Answer: </u>
clerk A and clerk B can simultaneously stock a shelf in
minutes
<u>Explanation:</u>
Let the first clerk be A and the second clerk be B
A can stock a shelf in 20 min
B can stock a shelf in 45 min
Consider the complete work to be W
A’s rate of stocking =
per minute
B’s rate of stocking =
per minute
When, A and B work simultaneously, rate of work done = 
Total work done simulatenously = 
=
Therefore, clerk A and clerk B can simultaneously stock a shelf in
minutes
