39.95 + 9.80 = 49.75
70.23 - 49.75 = 20.48
20.48 / 0.32 = 64
The truck was driven 64 miles.
Answer:
A person who watches 8.5 hours of TV can do 30.4 sit ups.
Step-by-step explanation:
The regression equation is used to predict or estimate the value of the response (or dependent) variables using the information about the explanatory (or predictor) variables.
The general form of a regression equation is:

Here,
<em>y</em> = dependent variable
<em>x</em> = independent variable
<em>a</em> = intercept
<em>b</em> = slope
The regression equation representing the relationship between hours of TV watched per day (<em>x</em>) and number of sit ups a person can do (<em>y</em>) is:

Compute the number of sit ups a person who watches 8.5 hours of TV can do as follows:


Thus, a person who watches 8.5 hours of TV can do 30.4 sit ups.
Answer:
volume = lenght x width x height
v= 12x20x14
v=3,360 in³
Slope is rise over run. Go up 1 unit, right 4 units to get to the next point.
the slope is 1/4
