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.

The area of a square is given by the expression square inches. Find an expression that represents the length of one side of the
Verizon [17]

Answer:

A. x-6

Step-by-step explanation:

The area of a square is given by the expression x^2-12x+36 square inches. Now we need to find an expression that represents the length of one side of the square, in inches. To do that we need to factor x^2-12x+36.

x^2-12x+36

=x^2-6x-6x+36

=x(x-6)-6(x-6)

=(x-6)(x-6)

=(x-6)^2

Since area of square is given by (side)^2

Hence one side of square is (x-6).

So choice A. x-6 is correct.

Solve the inequality: -6n - 12 >= 3(-n + 12)
Verizon [17]

Answer:

-16 > n or n < -16

Step-by-step explanation:

First, we can write the inequality and distribute.

-6n-12 > 3(-n+12)

-6n-12 > -3n+36

Get rid of a variable first (it makes solving a lot easier). We can add 6n to both sides.

-6n-12 > -3n+36

<u>+6n          +6n</u>

-12 > 3n+36

Now, we can subtract 36 on both sides.

-12 > 3n+36

<u>-36         -36</u>

-48 > 3n

Divide by 3 on both sides.

-48 > 3n

<u>/3       /3</u>

-16 > n or (if it's easier) n < -16

Hope this helps!! Have a wonderful day C:
