Given:Sample mean= 57
Standard Deviation= 9
score of 59
we go to our standard formula:
(score - mean) / sd = z
(59 - 57) / 9 = z
2/9 = z
0.2222 = z
Failing score cutoff would be equal to Mean - 2SD = 67 - 2(9) = 48 is failing score cutoff.
She had to make a 90 flat
hope this helps (;

To multiply 13.26 times 23, we first have to set it up vertically.
13.26
x 23
--------
3978
2652
----------
30498
Adding in the decimal, we get 304.98, because the total amount of decimal numbers in the equation, is 2. Therefore, the answer will have 2 decimal numbers. I hope this helps! :D But, if you don't understand how to multiply, tell me. I'm pretty sure that you do, but you know, just in case!
