Distance feet X 0 2 6 9 12 13 15
Height (feet) Y 4 8.4 12.1 14.2 13.2 10.5 9.8
(a) Write the quadratic regression equation mal models the data Letx=distance in feet and let y= height in feet Round all numbers to the nearest hundredth
(b) Use the equation to estimate the height of basketball when shot from 20 feet. Show your work.​

Answer 1

Answer:

a) $y = 0.118x^{2} +2.112x+4.215$

b)height = 896.2 feet

Step-by-step explanation:

for b, substitute 20 in place of x in the first equation.
