We want to factor the following expression: 9x^6 + 6x^3y + y^2

Which pattern can we use to factor the expression?
U and V are either constant integers or single-variable expressions.

Choose 1
A. (U+V)^2 or (U-V)^2
B. (U+V)(U-V)
C. We can't use any of the patterns.

People end up tossing 12% of what they buy at the grocery store. assume this is the true population proportion and that you plan to take a sample survey of 540 grocery shoppers to further investigate their behavior. a. calculate the mean and the standard error for the sample proportion p. b. describe the sampling distribution of p in part a. draw a graph of this probability distribution with its mean and standard deviation. what is the probability that your survey will provide a sample proportion more than 15%? c. d. population proportion? what is the probability that your survey will provide a sample proportion within + 0.03 of the
