The wall street journal reported that approximately 25% of the people who are told a product is improved will believe that it is, in fact, improved. the remaining 75% believe that this is just hype (the same old thing with no real improvement). suppose a marketing study consists of a random sample of seven people who are given a sales talk about a new, improved product. compute the mean and standard deviation of this probability distribution

14

step-by-step explanation:

14 x 3 = 42

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula

a c

step-by-step explanation:

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
