Answer:
The expression is not factorable with rational numbers.
Step-by-step explanation:
Answer:
c
Step-by-step explanation:
range is the y-axis coordinates
You can translate to:
F ÷ 28 = 24
F/28 = 24 Cross Multiply
F = 28 * 24
F = 672
Answer:
x = -2,0,2
Step-by-step explanation:
9x^3 - 36x = 0
Factor out 9x
9x(x^2 -4) =0
Factor inside the parentheses, which is the difference of squares
(a^2 -b^2 = (a-b)(a+b)
9x (x-2)(x+2) = 0
Using the zero product property
9x =0 x-2=0 x+2 =0
x=0 x=2 x=-2
x = -2,0,2
Answer:
Step-by-step explanation:
Let X be length of life of the participants in the plan.
Given that X is N(68,3.5)
We convert this to standard normal score z using
![z=\frac{x-68}{3.5}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7Bx-68%7D%7B3.5%7D)
a) proportion of the plan recipients that would receive payments beyond age 75=![P(X\geq 75) = P(Z\geq 2)\\= 0.025](https://tex.z-dn.net/?f=P%28X%5Cgeq%2075%29%20%3D%20P%28Z%5Cgeq%202%29%5C%5C%3D%200.025)
b) proportion of the plan recipients die before they reach the standard retirement age of 65=![P(X\leq 65) = P(z\leq -0.86)\\=0.5-0.2764\\=0.2236](https://tex.z-dn.net/?f=P%28X%5Cleq%2065%29%20%3D%20P%28z%5Cleq%20-0.86%29%5C%5C%3D0.5-0.2764%5C%5C%3D0.2236)
c) x for 86% ceased
