Answer:
An individual who spent 30 minutes weight lifting will burn approximately 142.4768 calories.
Step-by-step explanation:
Given;
yˆ = 8.6067x + 116.6567 ............................... (1)
Where;
yˆ = The average number of calories burned by a 160 lb individual
x = Amount of time spent weight lifting
Since x is amount of time spent weight lifting, this implies that for an individual who spent 30 minutes weight lifting, x = 30
Substituting x = 30 into equation (1), we have:
yˆ = (8.6067 * 30) + 116.6567
yˆ = 25.8201 + 116.6567
yˆ = 142.4768
Therefore, an individual who spent 30 minutes weight lifting will burn approximately 142.4768 calories.
