400
because you need to divide 36/0.09=400
I think it is 989 or 899
*3 digit number*
*26 sum*
Last two digits are the same

This can be solved by using a standard normal distribution table. The z-score for 34 pounds is 1, the reason being that 34 is one standard deviation above the mean of 28 pounds.
Can use the table to find the cumulative probability for z = 1.00 and post the result? If you do this we can do the next simple steps.
4 is the nearest integer
as a decimal this number would be 3.5, which would round up to 4.
12/15
Divide 12 by 15 and then you should get 0.8
0.8 is obviously equal to 8/10ths or 80%
Hope this helps :)
