Let's say the problem is 4^3 you would write out 4×4×4=64 if the problem is 4×4 then you would write out 4+4+4+4=16. hope this helps
Answer:
Step-by-step explanation:
Step-by-step explanation:
A) opposite sides in a rectangle is always equal
B) 9x+12 = 4x +47
Transpose = 9x - 4x = 47 - 12
solve = 5x = 35
Divide both sides by 5
x = 7
Answer:
AC=96
Step-by-step explanation:
If B is the midpoint of AC then AB is equal to BC there for you can find AC by adding AB and BC (AB+BC=AC) so in this case it would be 48+48=96
Answer:
The probability of receiving reimbursement within 42 days of filing is 0.8849 = 88.49%
Step-by-step explanation:
Let
the probability of being reimbursed in an interval of a to b days, we want 
First, standardize x by doing the change

where
is the mean of our original distribution and
the standard deviation. So

This change transforms the original distribution in a normal distribution N(0,1) with mean 0 and standard deviation 1.
This is done in order to easily compute the area under the normal curve.
Since,

we then have

And we want the area under the normal curve between -7.2 and 1.2. This can be done either by using a table or a computer, and we find this area is 0.8849,
Hence, the probability of receiving reimbursement within 42 days of filing is 0.8849 = 88.49%
