Sonja and Jake just got married. They received $4500 in gift money and deposited it into a savings account that pays 2.85% simple interest. How much will they have in savings after 3 years?

Group of answer choices

A. $9,000.00

B. $4,884.75

C. $384.75

D. $38,475.75

c. $384.75

Step-by-step explanation:

if the interest is calculated yearly, then 2.85% of $4500 is $128.25

times 3 years is $384.75

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;
