Convenience samples a. are typically not representative of the entire population. b. take place at 7-11, Stop & Go, or other convenience stores. c. take place at convenience stores and are nonprobability samples. d. are nonprobability samples. e. are nonprobability samples and are typically not representative of the entire population

it is b)

hope this : )

step-by-step explanation:

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.
