Mr. lang must give each child 4/6 of a cup of juice. how much juice does mr. lang have to buy for 4 children?

Mr. Lang must buy 8/3 cups of juice.

Step-by-step explanation:

In order to find this, multiply the amount of juice each kid gets by the amount of kids.

4/6 * 4 = 16/6

This fraction can be reduced.

16/6 = 8/3

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;
