HELP Every year in Delaware there is a contest where people create cannons and catapults designed
to launch pumpkins as far in the air as possible. The cquation y = 15 + 110x- 16x2 can be
used to represent the height, y, of a launched pumpkin, where x is the time in seconds that the
pumpkin has been in the air. What is the maximum height that the pumpkin reaches? How
many seconds have passed when the pumpkin hits the ground? (Hint: If the pumpkin hits the
ground, its height is 0 feet.)
The pumpkin's maximum height is 204.06 feet and it hits the ground after 7.01 seconds.
The pumpkin's maximum height is 3.44 feet and it hits the ground after 7.01 seconds.
The pumpkin's maximum height is 204.06 feet and it hits the ground after 3.44 seconds.
The pumpkin's maximum height is 3.44 feet and it hits the ground after 204.06 seconds.

The parabola y = x² - 4 opens: a.) up b.) down c.) right d.) left

In a sample of 2023 u.s. adults, 373 said franklin roosevelt was the best president since world war ii. two u.s. adults are selected at random from the population of all u.s. adults without replacement. assuming the sample is representative of all u.s. adults, complete parts (a) through (d). (a) find the probability that both adults say franklin roosevelt was the best president since world war ii. the probability that both adults say franklin roosevelt was the best president since world war ii is (round to three decimal places as needed.) (b) find the probability that neither adult says franklin roosevelt was the best president since world war ii. the probability that neither adult says franklin roosevelt was the best president since world war ii is (round to three decimal places as needed.) (c) find the probability that at least one of the two adults says franklin roosevelt was the best president since world war ii. the probability that at least one of the two adults says franklin roosevelt was the best president since world war ii is (round to three decimal places as needed.) (d) which of the events can be considered unusual? explain. select all that apply. the event in part left parenthesis a right parenthesis is unusual because its probability is less than or equal to 0.05. the event in part (b) is unusual because its probability is less than or equal to 0.05. none of these events are unusual. the event in part (c) is unusual because its probability is less than or equal to 0.05.
