If you order 3 pizzas, you will get 30 slices of pizza. How many slices are there in one pizza?

There are 10 slices in one pizza.

Step-by-step explanation:

30 ÷ 3 = 10

10 slices

Step-by-step explanation:

30÷3=10 meaning every pizza will have 10 slices and 2 pizzas will have 20.

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;

x=0
