Answer:
x = 1
Step-by-step explanation:
4x + 6 - x = 7 + 2x
3x + 6 = 7 + 2x
3x - 2x = 7 - 6
x = 1
Altho' 2 is a factor of both 8 and 64, we cannot "find the value of 2" because that's already given.
I believe you may have meant "<span>Find the value of z in the following equation: 8z=64".
We can solve that equation for z: z = 64/8, or z = 8 (answer).</span>
V = 4/3 * pi * r^3
V = 4/3 * 3.14 * 21^3
Simplify exponent:
V = 4/3 * 3.14 * 9261
Multiply:
V = 38772.72
Y ~ Po (λ)
P(Y < 2) = P(Y ≤ 1) = 0.04
Plug into the pdf for Po(λ), and solve for λ
After that, use your answer to find P(Y > 5)
0.06 or you can just put 6.
Basically, you have to multiply 30% x 20.
Glad I could help☺️
