The number of moviegoers who bought tickets for a summer blockbuster can be modeled by the equation , where w represents the number of weeks after the movie's release. Which of the following
statements is true?
f (w) = 9,250,000 (4/5)^w
А
There were 7,400,000 people who bought tickets to the movie the first week it was out.
B
There were 9,250,000 people who bought tickets to the movie the first week it was out.
С
Each week, there was an 80% increase in the number of people who bought tickets to the movie.
D
Each week, there was an 80% decrease in the number of people who bought tickets to the movie.

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;

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.
