Aconvenience store manager wants to find out

what type of music customers would like to hear

while they shop. the manager decides to survey

every twentieth person who enters the store in

one day.

is the type of

sampling method used.

a. simple random sampling

b. systematic random sampling c. stratified sampling d. cluster sampling

hi!

i believe that john has 55 pieces of candy left.

!

b. x + 1

step-by-step explanation:

i'am smart

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
