34.25

Step-by-step explanation:

4.5 + 19.75 = 24.25

Step-by-step explanation:

Plug in 5 at the bottom fpr the answer because we know we don't have to add anything else to that. Now move to 7 and blank. Since its addition we knkw we have to make it to were we carry a number since we can't get 2 any other way. So 7+5 equals 12 so carry your one over. 9+4+1 equals 14 and then from there you carry the one over again. Since you know you already have one therw and you are trying to get two that blank space will be a one as well since 1+1 equals 2.

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;
