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
Answer:
9.3
Step-by-step explanation:
if both travel at same speed they will take equal distance and time to reach the middle and collide.
hence, 27/2 =13.5km
speed=distance/time
time = distance/speed
time= 13.5/87 = 0.15517mm hr
0.15517×60 = 9.31minutes
