The number of students enrolled in math courses at Portland Community College has grown over the years. The formulas
M = 0.32x + 5.3
W = 0.5x + 5.6
N = 0.03x +0.2
describe the numbers (of thousands) of men, women, and gender-non-binary students enrolled in math courses at PCC x years after 2005. (Note this is
an exercise using randomized numbers, not actual data.) Give a simplified formula for the total number T of thousands of students at PCC taking math
classes x years after 2005. Be sure to give the entire formula, starting with T=

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;

96 39 cause 135 -96=39 im smart (i used a calculater)

y=sec x is the correct answer
