<em> </em><em>=</em><em> </em><em>5</em><em>+</em><em>7</em><em>/</em><em>2</em>

<em>=</em><em>1</em><em>2</em><em>/</em><em>2</em>

<em>=</em><em> </em><em>6</em>

<em>c.</em><em> </em><em>summation </em><em>FX=</em><em>5</em><em>2</em>

<em> </em><em> </em><em> </em><em> </em><em>N=</em><em>1</em><em>0</em>

<em>Mean=</em><em> </em><em>summationfx/</em><em>N</em>

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.

Jenny can swim 10 laps In 5 minutes. How many laps should she swim in 1/3 of an hour?
DIA [1.3K]

1/3 of an hour is 20 minutes. If show 10 laps in 5 minutes, just divide 20 by 5, which gives you 4, then multiply 4 times 10. She can swim 40 laps in 1/3 of an hour. Hope that helps. Mark Brainliest if it does. Thank you!
