To find the percent of the tiles in HI! that are in the H, first find either a fraction or a decimal written hundredths, since percent is a number out of 100. Then convert the hundredths to a percent your answer

Step-by-step explanation:

As we can see in the image below, the number of tiles that form the word HI!, is ; this represents the or the total.

Now, if we count the number of tiles in H, this number will be . So, we have to find what percent this number represents by a Rule of Three:

If:

----

----

Then:

This is the percent of tiles in H.

24+x=y

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;
