32 boxes of orange juice and 56 boxes of apple juice each shelf in the cupboard can hold 8 boxes of juice. What is the least number of shelves needed for all the juice boxes?

11

Step-by-step explanation:

First you add both of the boxes of juice. 32 + 56. Which you should get the total of 88 boxes. You then divide 88 by 8 which you get 11.

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;
