Answer: a.   Consumption is increasing at a rate of 5 calories per year.

Step-by-step explanation:

Given: The scatter-plot shown includes the (blue) least-squares regression line, whose equation is y = .975 + .005x, where y is calories (in thousands) and x is years after 1960.

Here, the slope of the line = 0.05 thousand=0.005\times1000=5

We know that the slope of the line tells about the rate of change of function y with respect to x (independent variable).

Since, the slope of the given line is positive then the dependent variable increase with respect to the independent variable.

Therefore the consumption of calories is increasing at a rate of 5 calories per year.

The scatterplot shown includes the (blue) least-squares regression line, whose equation is y = .975 + .005x, where y is calories (in thousands) and x is years after 1960. Choose the correct statement.

Answer: In the given regression equation, the calories are in thousands. Therefore, the slope 0.005 (0.005 x 1000 =5 calories)  means the consumption is increasing at a rate of 5 calories per year.

Hence the option a. Consumption is increasing at a rate of 5 calories per year. is correct

The answer would be 25 because all of the others are prime numbers, meaning they can only be divided by themselves and 1. So it would be C.
