The vet told jake that his dog, rocco, who weighed 55 pounds, needed to lose 10 pounds. jake started walking rocco every day and changed the amount of food he was feeding him. rocco lost half a pound the first week. jake wants to determine rocco’s weight in pounds, p, after w weeks if rocco continues to lose weight based on his vet’s advice. the equation of the scenario is . the values of p must be

answer: i would say b

step-by-step explanation:

with the way the question is worded, i believe b is the answer

typically if you want , you would actually put questions here for us to you. but hey, that's just me. maybe someone will magically answer the questions for you without knowing what they are.

where is the figure

irst, find the z score of a score of 80. this is given by the formula z = (x-u)/o, where x is the score, u is the mean, and o is the standard deviation. this gives

z = (80-78)/12 = 1/6 = .1667

now, find what percentile a z score of 1/6 correlates to in the normal distribution.

a z score of 1/6 = .1667 is equivalent to the 56.36th percentile of the distribution. so the probability a score is over this is 1-.5636 = .4364

the mean of a sample mean is equal to the original mean. however, the standard deviation of a sample mean is equal to the original standard deviation divided by the square root of n (sample size). so the new standard deviation is 12/sqrt(16) = 3.

the new z score is 80-78/3 = 2/3 = .667. this is equivalent to the 74.86th percentile. so the probability that the mean will be greater than this score is 1-.7486 = .2514.
