Answer is 526 because you need to find Area of the Front face multiplied by two area of the side face multiply that by two and then area of the top face and multiply that by two and then add them togetherDid you get an answer of 526. Hope it helps
(2x - 2y)(2y + 8)
2x(2y+ 8) - 2y(2y + 8)
2x(2y) + 2x(8) - 2y(2y) - 2y(8)
4xy + 16x - 4y^2 - 16y
The answer is B.
Hope you understand it and see what I did.
Answer:A)The conditional relative frequency among widowed employees of those widowed working at grade 2 or below= 28/42 = 66.67%
Step-by-step explanation:
In a two way frequency table, conditional relative frequency is it’s a fraction that tells us how many elements of of a group have a certain characteristic.
Here In a study about the relationship between marital status and job level, 8,235 males at a large manufacturing firm reported their job grade (from 1 to 4, with 4 being the highest) and their marital status.
from the given two way frequency table,
Number of widowed employees at grade 1 =8
Number of widowed employees at grade 2=20
∴ Number of widowed employees at grade 2 or below=8+20=28
And the total widowed employees working =42
Now the conditional relative frequency among widowed employees of those widowed working at grade 2 or below=
Therefore, the conditional relative frequency among widowed employees of those widowed working at grade 2 or below= 28/42 = 66.67%
