1 answer:
Vinil7 [7]3 years ago
7 0

Answer:

96

Step-by-step explanation:

To find this answer, I just did a bit of guess and check. I took 71+65+x (random numbers in the general area of those numbers). Then I divided that by 3 to find the average of the three numbers. So, (71+65+96)/3=77.(3). (95 is too small because its exactly 77 when the average is found.) Hope this helped!

16% of a number is 60. What is that number?<br><br> A375<br> B 432<br> C 456<br> D753
Vlad1618 [11]

Answer:

Its A: 375

Because, if you take 26.6 you have to round it. So, the 6 behind the decimal is over 5 so make the other 6 in front of the decimal a 7. So, the 7 will add 1 to the 2 to make it 3. And i forgot how to get the 5, but trust me dis is right. :3

A population has a mean µ = 6 and ∑x = 48. How many scores are in the population?
maks197457 [2]

Answer:

8

Step-by-step explanation:

Recall the formula for the population mean of a data set:

\mu=\frac{\sum x}{N}

We already know that μ is 6 and the sum is 48. Substitute:

6=\frac{48}{N}

Divide both sides by 48:

\frac{1}{8}=\frac{1}{N}

Reciprocal of both sides:

N=8

Thus, there are 8 scores in the population size.

And we're done!
