A survey of 65 customers was taken at a bookstore regarding the types of books purchased. The survey found that 40 customers purchased mysteries​, 32 purchased science fiction​, 22 purchased romance novels​, 17 purchased mysteries and science fiction​, 12 purchased mysteries and romance novels​, 9 purchased science fiction and romance novels​, and 4 purchased all three types of books. ​a) How many of the customers surveyed purchased only mysteries​? ​b) How many purchased mysteries and science fiction​, but not romance novels​? ​c) How many purchased mysteries or science fiction​? ​d) How many purchased mysteries or science fiction​, but not romance novels​? ​e) How many purchased exactly two types of​ books?

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
