Answer: A) 13
<u>Step-by-step explanation:</u>
Mean - 1 SD: 20.2 - 2.4 = 17.8 --> (18)
Mean + 1 SD: 20.2 + 2.4 = 22.6 --> (23)
Now, find the values on the histogram for 18 through 23:
2 + 3 + 4 + 3 + 1 + 1 = 13
Answer:
9
Step-by-step explanation:
-3/4*(-12)
3/4*12
3*3=9
Answer:
-5/2 or -2.5.
Step-by-step explanation:
The remainder theorem states that if the polynomial f(x) is divided by (x - a) then the remainder is f(a).
To find the remainder we put x = -3/2 ( by solving 2x + 3 = 0).
The remainder = 4(-3/2)^3 + 6(-3/2)^2 + 3(-3/2) + 2
= -27/2 + 27/2 - 9/2 + 2
= -9/2 + 4/2
= -5/2.
