Answer:
Step-by-step explanation:
1. - 3x + 32 = - x - 12
-3x + x = - 12 - 32
-2x = - 44
x = 44/2 = 22
2. 8x + 16 = x + 9
8x - x = 9 - 16
7x = - 7
x = - 7/7
= - 1
3. 3x + 2 = 2x - 55
3x - 2x = - 55 - 2
x = - 57
Answer: 0.47
Step-by-step explanation:
Given that
n = 100, probability of rolling 1 = 1/6
binomial approximation
np = 100 ( 1/6) = 16.667
standard deviation = √ 100 × 1/6 ×5/6 = 3.7627
P ( 9 ≤ X ≤ 16 )
= P ( 8.5 < X < 16.5 )
so,
= P ((8.5 - 16.6667) / 3.7627 < Z < (16.5 - 16.6667) / 3.7627
= P ( -2.17 < Z < -0.04 )
= 0.484 - 0.015
= 0.47
Therefore the approximate probability that you will roll between 9 and 16 ones is 0.47
Answer: neither
Explanation:
x^3 can be either even or odd
Ex: x = 2 then 2^3 = 8 = even
Ex: x = 3 then 3^3 = 27 = odd
x^2 can also be either even or odd
Ex: x = 2 then 2^2 = 4 = even
Ex: x = 3 then 3^3 = 9 = odd
Since both can be even and odd
Even/Odd + Even/Odd = Even/Odd
So the result will be either even or odd
The answer is 102060 because if you multiply 54000 by 1.89 you get 102060
