Write a ratio for the situation in three ways, comparing the first quantity to the second quantity. in largo city, about one in every nine homes contains four televisions.

Step-by-step explanation:

1/9

(1*4) / (9*4) = 4/36

(1*4) / (9*4) = 5/45

The first one is the ratio as it is stated in the problem.

The second one multiplies top and bottom by 4

The third one multiplies top and bottom of the top ratio by 5.

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;
