In your class, 7 students do not receive a weekly allowance, 5 students receive $3, 7 students receive $5, 3 students receive $6, and 2 students receive $8. what is the mean weekly allowance?
( this is how you would answer it)
the mean weekly allowance is dollars.

The mean weekly allowance is 3.5 dollars

Step-by-step explanation:

Given: Number of students receive no amount =7

Number of students receive $3=5

Then, total amount 5 students receive =

Number of students receive $5=7

Then, total amount 7 students receive =

Number of students receive $6=3

Then, total amount 3 students receive =

Number of students receive $8=2

Then, total amount 2 students receive =

Now, the total amount all students receive=

The total students =

Now, Mean=

Hence, The mean weekly allowance is 3.5 dollars.

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! : )
