Anormally distributed data set has a mean of 25 and a standard deviation of 2. which percentage of the data falls between 23 and 25?

The answer is %34.13

Step-by-step explanation:

If mean of a normal distributed data set is 25, it will mean %50 of the data is above 25 and %50 of the data is below 25.

Than we need to subtract probability of being less than 23 from %50.

First z value need to be found for 23:

probablity of z=-1 is %15.87

Then 50-15.87=34.13 %34.13 of the data falls between 23 and 25

y-1700=200(x+4)

step-by-step explanation:

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had

answer4 to the second power is 16

and 4 to the third power is 64,
