Aset of data with a mean of 45 and a standard deviation of 8.3 is normally distributed. find the value that is +3 standard deviations away from the mean. 48.0 78.9 20.1 69.9

D. 69.9

Step-by-step explanation:

We have been given that a set of data with a mean of 45 and a standard deviation of 8.3 is normally distributed. We are asked to find the value that is +3 standard deviations away from the mean.

To find the value that is 3 standard deviation away from mean, we will multiply 3 by standard deviation and ad the result to mean.

Therefore, 69.9 is 3 standard deviation away from mean of or given data set and option D is the correct choice.

side xy = 10

sin(x) = 4/5

cos(x) = 3/5

tan(x) = 4/3

step-by-step explanation:

76%

step-by-step explanation:

24% are dogs and the remaining is 76% because 100-24=76
