What is 0.25x20 show and explain your answer

5

Step-by-step explanation:

0.25 x 20 = 5

To make it easier we can make the decimal 0.25 into the fraction 1/4. In this case, we would also make 20 into a fraction. Which would give us 20/1. Now we would multiply the numerators (1 and 20) together and we get 20. Then we would multiply the denominators (4 and 1) to get 4. From there we can write the fraction (or the division problem) as 20/4. We can divide both sides by four to get 5/1. Which gets us our answer of 5.

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;
