A friend of yours, a senior, took the Graduate Record Exam in September and scored in the 99th percentile. InFebruary, your frie
Alecsey [184]

Answer:

"differential selection"

Step-by-step explanation:

If your friend took the test twice and passed both times with a score above 90% then the minor difference in price is most likely due to "differential selection". The first test had  questions that he had a little more experience in solving, while the second time he was most likely given a couple questions that he wasn't as prepared for as he was the first time. This is most likely the cause for the difference in percentiles.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

svetoff [14.1K]

Answer:

C. 5 goes into 100 twenty times, and 1 times 20 is 20

Step-by-step explanation:

Since, we know that when we multiply both numerator and denominator of a fraction by a same number then we obtain an equivalent fraction,

Here, the given fraction,

\frac{1}{5}

By the above statement,

\frac{1}{5}=\frac{1\times 20}{5\times 20}=\frac{20}{100}

Now,

a\%=\frac{a}{100}

\implies \frac{20}{100}=20\%

Hence,

\frac{1}{5}=20\%

Option C is correct.
