Aloan of $19,221 was repaid at the end of 17 months. what size repayment check (principal and interest) was written, if a 9.7% annual rate of interest was charged? the amount of the repayment check was $ 45447.53). (round to two decimal places.)

The amount of the repayment check was $21862.29.

Step-by-step explanation:

Principal P = $19221

Rate r = 9.7% = 0.097

Time t = 17 months = years

= $2641.29

The loan repayment is the original principal plus the interest.

= dollars

The amount of the repayment check was $21862.29.

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;

b
