In an EFE Matrix, how much more important is a weight of 0.20 than a weight of 0.15? A. 50% B. 33% C. 25% D. .05% E. 5.0%
1 answer:
Answer: B. 33%
Step-by-step explanation:
- In Mathematics , a percentage is basically a process of dividing the numerator by the denominator , then multiply the answer by 100.
We use Mathematical Formula :
Since , Difference between the Weight of 0.20 and Weight of 0.15 = 0.20-0.15=0.05
Then, substitute the value in formula , we get
Hence, the weight of 0.20 is 33% more important than a weight of 0.15.

Given
Area of the regular pentagon is 6.9 cm².
Find out the perimeter of a regular pentagon
To proof
Formula
Area of regular pentagon is
As given in the question
area of regular pentagon = 6.9 cm²
now equating the area value with the area formula.
Now put
√5 = 2.24 ( approx)
put in the above equation
thus
a² = 4.01
a = √ 4.01
a = 2.0 cm ( approx)
As perimeter represented the sum of all sides.
i.e regular pentagon have five sides of equal length.
Thus
perimeter of the regular pentagon = 5 × side length
= 5 ×2.00
therefore the perimeter of the regular pentagon = 10cm
option c is correct
Hence proved
