The sweater Ingrid wants to buy is $30. It is on sale for 33% off. If the sales tax is
7%, what is the total cost of the sweater?
Round to the nearest cent, if necessary.

Sweater will be $21.51

Step-by-step explanation:

cost of sweater $30.00

Sale of 33% off comes to $9.90/off ($30 × 33% = $9.90)

$30.00 - $9.90 =$20.10

Sale cost of sweater is $20.10

$20.10 × 7% sales tax = $1.41

$20.10 + $1.41 = $21.51

it will be a cylinder. with a diameter of 8 and 4 single pieces high

step-by-step explanation:

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;
