Z score is a statistical that corresponds to the standarization of the regular score to a normal dsitribution

The formula for Z score is Z = [X - mean ]./ (standar deviation)

Here X = 930.00; mean = 900.00; and standard deviation = 15.00

Then, Z = [930.00 - 900.00] / 15.00 = 30.00 / 15.00 = 2.00

zloy xaker [14]

Multiplying both sides of this equation by 3, to eliminate the fraction, we get:

9 + m = 6.

Next, we subtract 9 from both sides to isolate m:  m = 6 - 9 = -3

Then m = -3.

Check:  Subst. -3 for m in this equation:

9 - 3       6

------- = ------ = 2 (as expected).  Thus, m = -3 is correct.

  3          3



Problem #10:

4n - 9 = -9     Add 9 to both sides:  4n = -9 + 9 = 0.

Divide both sides by 4:  n = 0.

Check:  Substitute 0 for n:  4(0) - 9 = -9  is true.

Which of the following graphs could be the graph of the function f(x)=-0.08x(x^2-11x+18)?
MariettaO [177]

Answer:

option C

Step-by-step explanation:

f(x)=-0.08x(x^2-11x+18)

Factor the parenthesis and find out the x intercepts

(x^2-11x+18)

We find out two factors whose product is 18 and sum is -11

-9  and -2 gives us product 18

-9  -2 gives us sum -11

(x^2-11x+18) =(x-9)(x-2)

f(x)=-0.08x(x^2-11x+18)

f(x)= -0.08x(x-9)(x-2)

set f(x) =0  and solve for x

-0.08x(x-9)(x-2) =0

-0.08x =0, so x=0

x-9 = 0 , so x=9

x-2 =0 , so x=2

x intercepts are (0,0) (2,0)  and (9,0)

x intercepts are not repeating

so the graph crosses x -axis at x=0, 2,9

option C is correct

The graph is attached below4
