During one game, the dallas cowboys punter was called upon to punt the ball eight times. on one of these punts, the punter
struck the ball at his own 30-yard line. the height, h of the ball above the field as a function of time, t, in seconds can be partially
modeled by the following table:
10.6
28.56
1.2
43.10
46.12
37.12
17.60
use your graphing calculator, to obtain a quadratic regression function for these data. round the values of a, b, and c to four
decimal places.
a. h(t) --15.97521° +52.8875++ 2.5536
c. h(t) - 15.975212 + 52 8875+ + 2.5536
b. h(t) = -15.975272 +52.8875+ + 2.5536
d. h(t) = -15.975272 - 52.8875+ + 2.5536

In a test for esp (extrasensory perception), the experimenter looks at cards that are hidden from the subject. each card contains either a star, a circle, a wave, a cross or a square.(five shapes) as the experimenter looks at each of 20 cards in turn, the subject names the shape on the card. when the esp study described above discovers a subject whose performance appears to be better than guessing, the study continues at greater length. the experimenter looks at many cards bearing one of five shapes (star, square, circle, wave, and cross) in an order determined by random numbers. the subject cannot see the experimenter as he looks at each card in turn, in order to avoid any possible nonverbal clues. the answers of a subject who does not have esp should be independent observations, each with probability 1/5 of success. we record 1000 attempts. which of the following assumptions must be met in order to solve this problem? it's reasonable to assume normality 0.8(1000), 0.2(1000)%30 approximately normal 0.8(1000), 0.2(1000)% 10 approximately normal srs it is reasonable to assume the total number of cards is over 10,000 it is reasonable to assume the total number of cards is over 1000

If you double the input of a function and it results in half the output, and if you triple the input and it results in a third of the output, what can be guessed about the function? check all that apply.
