•$1,000 invested at 5% for 10 years.

simple interest. compound interest

need fast ill give you

$1,628.89 this is if it is compounded once a year

Step-by-step explanation:

Using the formula A=P[1+(r/n)]^(nt)

where

A=the ending amount

P=starting amount

r=interest rate

n=number of times interest is applied annually

t=time (years)

A=1000(1+(0.05/1))^(10)(1)

A=1000(1.05)^10

A=1000(1.62889)

A=1,628.89

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;

the answer is 13/48
