Answer:
10000 options
Step-by-step explanation:
There are 10 options of digit from 0 to 9. It means there are 10 options for the first slot, 10 for the 2nd slot, 10 for the 3rd slot, and 10 for the last slot of each of the 4 slots of the password. For all 4 passwords the total amount of choices would be

Since 12% of them are damaged, that means the percentage of them that aren't 88%.
The easiest way to do it is to divide 88 from 1,144, written as 1,144<span>÷88.
That's 13. So, then you would multiply 13 by 100. To get the total amount of onions. That'd be 1,300.</span>
Answer:
0.525 = 52.5%
Step-by-step explanation:
Moment generating function ( Mx(t) ) = ( 4 / 4-t)^3
Reimbursement by Insurer = 70%
<u>Determine the expected reimbursement by insurer for policyholder</u>
d/dx (Mx(t) ) = d/dt ( 4 / 4-t)^3 = d/dt (1 - t/4 )^-3
= 3/4 ( 1 - t/4 )^-4 = 3/4
as t → 0
Given that the insurer reimburses 70% = 0.7
expected reimbursement = 0.7 * 3/4 = 0.7 * 0.75 = 0.525
