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

the answer is 5636.7

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i
