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%
sergij07 [2.7K]

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 : \dfrac{\text{Difference between the Weight of 0.20 and Weight of 0.15 }}{\text{Weight of 0.15}}\times100

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

=\dfrac{0.05}{0.15}\times100\\\\=\dfrac{5}{15}\times100\\\\ \dfrac{100}{3}\%\approx33\%

Hence, the weight of 0.20 is 33% more important than a weight of​ 0.15.

ryzh [129]

Joanna deposited $132000 and her interest amount is $359730.35

<u>Step-by-step explanation:</u>

Monthly deposit = $275

Interest = 5.6%

Time = 40 years

After 40 years her account balance = $491730.35

If she deposit $275 monthly then after 40 years she will have deposited ,

= 275 x 12 x 40

= $132000

The remaining is her interest amount.

Interest amount = 491730.35 - 132000

= $359730.35

Joanna deposited $132000 and her interest amount is $359730.35
