Find the quadratic regression equation for the relationship of the horizontal distance and the height of the ball.

• y= -18x² + 2.11x + 4.21

• y= -.06x² +1.06x + 7.9

• y= -6x² +1.06x + 79

• y= -.12x² + 2.11x + 4.22

The table shown is comparing a person's foot length to their height in cm. Calculate a linear regression equation.

• y = 25.05x + 5.57

• y = 5.57x + 25.05

• y = -5.57x + 25.05

• y = 5.57x - 25.05

A researcher gathered data to predict the number of new types of plants (y) that will be in a state park after x years.  After making a scatter plot of the data, she determined the equation of a line of best fit to be
y = 0.25x + 8
Based on the equation, what is the number of new types of plants that will be in the park after 24 years?

• 8

• 14

• 32
