Hall-of-Fame pitcher Bob Gibson of the St. Louis Cardinals was one of the most dominant pitchers during the 1960s. The table shows his age and WHIP (walks + hits per inning pitched) for each year of his career, beginning in 1959. Lower WHIP values are better for pitchers. A) Calculate a quadratic model for these data using age as the explanatory variable.

B) Sketch the scatterplot, along with the quadratic model.

C) Calculate and interpret the residual for his famous 1968 season.

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

this answer is !

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
