1. A paper weight shaped like a triangular prism is shown in the picture. The height of the paper weight is 9 cm, and the volume of the pencil holder is 153 cm?.
What is the area of the base of the paper weight in square centimeters?

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed

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;
