<u>Answer:</u>
The correct answer option is E. [83 + 2(79) + 4(88)] × 1/7.
<u>Step-by-step explanation:</u>
We are given the quiz average, test average and final average for Sabra's grades for a class.
Given that her test average counts twice as much as her quiz average and final exam counts twice as much as her test average for her overall average:
÷ 
This can also be written as:
[83 + 2(79) + 4(88)] × 1/7
I know that 20% is out of 100.If I changed this problem to be a fraction problem,I would change that percent to 20/100.55 would be the denominater of the other fraction.Right now we're trying to find the numerator for the denominator of 55 to make this a complete fraction.Secondly,I would try to find a common denominator to get my answer.I'm going to make the common denominator......5500.As my teacher always said what you do to the bottom you do to the top and it goes the other way around too.So, i will times 20*55 to get my numerator.This equals 1100.Now I would divide this fraction by 100 to get my finished answer.The answer is 11 is 20% of 50.
Answer:
r ≈ 26%

Step-by-step explanation:
Total power generated by wind worldwide doubles every 3 years.
In a particular year, the world wind generating capacity was 85 thousand megawatts.
So, the formula for wind generating capacity W (in thousand megawatts) as a function of t. the number of years in the future will be given by
........ (1)
Therefore, for t = 1 year,
thousand megawatts.
Again, for t = 2 years,
thousand megawatts.
As the continuous growth rate is exponential, so, we can write
⇒
⇒ r = 25.99% ≈ 26% (Answer)
