Omar is painting a 24-square-foot wall. the wall is divided into squares that each measure 1 /4 square foot. how many squares is the wall divided into?

  96 squares

Step-by-step explanation:

The number of squares is ...

  (wall area)/(square area) = (24 ft²)/(1/4 ft²) = 24×4 = 96 . . . . squares

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;
