1. a football is kicked at ground level with an initial velocity of 64 feet per second. i. 2 y tt =− + 16 64 iv. ii. ( ) 2 y t =− − + 16 2 64 iii. y tt =− − 16 4 ( ) a. the maximum height of the football is b. the height after 3 seconds is c. the time when the football hits the ground is d. an estimate of the time when the football is 40 feet high is

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

hope i

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
