Karen has 7/8cup of ice cream. how many 1 / 3cup servings can she make? a. 7 / 24 b. 8/21 c. 1 5/24 d. 2 5 /8

D- 2 5/8

Step-by-step explanation:

7/8 ÷ 1/3

= 7 × 3/8 × 1

= 21/8 OR 2 5/8

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;

answer: i believe the answer is e
