Angie baked 100 cookies and 20 brownies. she wants to split them into equip groups for the bake sale. each group must have the same number of cookies and brownies, with none left over. what is the greatest number of groups she can make?

She baked;

100 cookies and 20 brownies.

Each group must have the same number of cookies and brownies.

Here we find the greatest common divider (GCD) of 100 and 20

The GCD is 20

Greatest number of groups is 20 and each group will have 1 brownie and 5 cookies.

step-by-step explanation:

f

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;
