(15 pts) A store finds that its sales decline after their ad campaign ends. The rate at which the daily sales decline is given as S'(t) = 225e -0.250 - 210, where t is the
number of days since the ads quit running. Suppose that their daily sales are 3700 units
at the time the campaign ends (t = 0). Find:
a. The function that describes the total daily sales, or S(t).
b. What the daily sales will be 7 days after the ads stop running.

step-by-step explanation:

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.

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;
