Venita is factoring the expression 32ab - 8b. She determines the GCF and writes the factored expression as 8b(4a - 0). Which best describes Venita's error? A. She incorrectly determined the GCF.

B. She subtracted the GCF from the second term in the expression instead of dividing.

C. She divided the GCF into the first expression instead of subtracting.

D. She divided each piece of the expression by different factors.

Proving the congruent supplements theorem

Arandom sample of size n 64 is taken from a population with population proportion p 0.38 describe the sampling distribution of p. draw a graph of this probability distribution with its a. mean and standard deviation. b. what is the probability that the sample proportion is greater than 0.5? what is the probability that the sample proportion is less than 0.3? d. what is the probability that the sample proportion is between 0.35 and 0.45?

Arandom sample of 15 observations is used to estimate the population mean. the sample mean and the standard deviation are calculated as 172 and 63, respectively. assume that the population is normally distributed. a. with 99 confidence, what is the margin of error for the estimation of the population mean? b. construct the 99% confidence interval for the population mean. c. construct the 95% confidence interval for the population mean. d. construct the 83% confidence interval for the population mean. hint: you need to use excel function =t.inv.2t to find the value of t for the interval calculation.
