For a normal distribution what percentage of data falls within one standard deviation of the mean
3241004551 [841]

Answer:

For a normal distribution 68% of data falls within one standard deviation from mean on both sides of mean

Step-by-step explanation:

A normal distribution's graph is a bell shaped curve that is completely described by its mean and standard deviation. Standard deviation is measured in terms of distance from mean.

34% of data is covered in one standard deviation from mean on one side.

Therefore, for a normal distribution 68% of data falls within one standard deviation from mean on both sides of mean ..

Find the complete factorization of the expression. 48x + 56xy A) 8x(6 + 7y) B) 8x(7 + 6y) C) 8xy(6 + 7) D) 8xy(13)
mel-nik [20]
Hello there!

The expression:48x+ 56xy

We know we can't add them together since 56 is being multiplied by y. We aren't going to combine 48x and 56xy. They will remain separate terms. 

We know that "C" and "D" are not the answers. 

However, we can check the following expressions to see if they match the given expression.

8x(6+7y)= 8x*6= 48x  8x*7y= 56xy <=== "A" is correct

"A" is the correct answer. 

I hope this helps!
