Calculating and interpreting residuals A group of young adults reported their average number of hours of exercise per week and measured their resting
heart rates. An approximate least-squares regression line was used to predict the resting heart rate from a given
number of hours of exercise per week.

the one that has a slope of 1/2 and is positive.

step-by-step explanation: 2 buckets 1 trip ; 4 buckets 2 trips and so on.

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
