Answer:
7. (7^2)(4^2) or 49 * 16
8.18^5
Step-by-step explanation:
7. You can do that or simplify the exponents.
8. When dividing two exponents you can subtract the exponentes. *(note i didn't simplify 18^5 because it said expression, and a simplified number is not an expression.)
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%
Amount using compound interest = 2400(1 + 0.034)^5 = 2400(1.034)^5 = 2400(1.1820) = $2,836.70
Amount using simple interest = 2400(1 + 5 x 0.034) = 2400(1 + 0.17) = 2400(1.17) = $2,808
Difference = $2,836.70 - $2,808 = $28.70
Therefore, <span>he will earn $28.70 more interest in 5 years if the interest were compounded annually</span> .
The error Alex made while simplifying the expression 7+(3x 1. 4)+5+2+(5x1. 4) is "he found the perimeter of the figure instead of the area".
<h3>How to find area of an object?</h3>
The area of an object is the product of the length and width of the objects.
Alex added the dimensions of the grid instead of multiplying them.
7+(3x 1. 4)+5+2+(5x1. 4)
For instance,
- Area of a rectangle = length × width
- Perimeter of a rectangle = 2(length + width)
Therefore, Alex found the perimeter of the figure instead of the area".
