The square root of 95 is 5 of5
<u>ANSWER</u>: 110
<u>EXPLANATION</u>:
Let these five numbers be a, b, c, d and e.
Then "<span>arithmetic means of 5 numbers is 100" implies
(a + b + c + d + e) / 5 = 100
>> a + b + c + d + e = 500
</span>And "arithmetic means of 2 of these numbers (suppose a and b) is 85" implies
(a + b) / 2 = 85
>> a + b = 170
Using these two equations, we have
(a + b) + c + d + e = 500
>> (170) + c + d + e = 500
>> c + d + e = 500 - 170
>> c + d + e = 330
So "t<span>he mean of the other 3 numbers (c,d and e)" is
</span>(c + d + e) / 3 = 330 / 3 = 110
Answer:
3.14
Step-by-step explanation:
The difference between her score and the mean is:
20 − 31 = -11
The number of standard deviations that equals is:
-11 / 3.5 ≈ -3.14
Her score is approximately 3.14 standard deviations below the mean.
Ok?? What about it? Dhehheehhs
