use a graphing calculator to perform the regression for the best-fit equation.

i came up with:

y= ax ²+bx+c
y=(-15.90)x^2+110.49 x+3.01

a= -15.90 b = 110.48; c= 3.01

i need with these:

determine the initial velocity of the baseball and the height of the ball when hit. round to
the nearest hundredth.

calculate how many seconds an outfielder has to position himself for the catch if he
intends to catch the ball 6 feet above the ground. show your work and round to the
nearest hundredth

1) letter c.

2) 4 square root of 9

hope this

step-by-step explanation:

0 and 5 minutes

step-by-step explanation:

given that one morning eight buses arrive late by the number of minutes given below:

0 8 2 6 9 2 0 7 8

write these in ascending order

0   0 2 6 7 8 8 9

in the afternoon two more buses arrive at the bus stop say by x and y minutes late.

total number of buses = 10

median = average of 4th and 5th after arranging in ascending order

since 4th entry is 6, the values of x and y should be below 6

also given 0 is the mode so either x or y or both should be 0 because then only 0 gets the maximum frequency and hence mode

thus we have

0 0 0 2 6 7 8 8 9 and another unknown entry which is below 6.

since median is 3.5, we have the unknown entry to be 5 only because then only median =( 2+5)/2

thus the after noon buses were late by 0 and 5 minutes.
