What is 5/8+3/4? Explain step by step.

11/8 or 1 3/8

Step-by-step explanation:

first you have to change the denominator to 8 in the 3/4, so that means you have to change the numerator too.

that gets you 6/8, so the new equation is

6/8+5/8

you only have to add the numerators, so it gives you 11/8.

to change it to a mixed number, all you have to do is find how many whole numbers (aka 8/8 in this situation) go into your improper fraction, and there is 1 in ours. you set that aside and you get 3/8 left over. You put those together and get 1 3/8

hope this helps! have a nice day!

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;
