In order to win the fall election, Joe Biden has decided to start a rumor about the presidents. He figures if he tells a certain number of people this rumor, and they intern tell the same number of people, eventually every person in the country will have heard it by election day.

Assume that if he tells five people, each of those five people will tell 5 more, etc.

Joe has seven days to spread the rumor, how many people will he need to tell so that everyone will have her there by the seventh day? Make sure you were able to back up your answer with math.

There are currently 255 million Americans were old enough to vote.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

step-by-step explanation:

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
