The answer would be 7/24
You can start by finding a common denominator. Since the lowest common denominator 3 and 8 have in common is 24 then that would be your denominator.
Then you can cross multiply 3*3= 9 and 2*8=16
16-9= 7
7/24
Then you are left with your answer:
is already in reduced terms.

Answer:
Step-by-step explanation:
In the normal distribution curve, we will have 5% below 10 months [horizontal axis] and 75% below 13 months [horizontal axis].
We need to find z-score using z-table [normal table] that corresponds to
5% = 0.05
and
75% = 0.75
Zscore formula:
Where mu is mean and sigma is standard deviation [these are the 2 parameters we are seeking]
So, 0.05 corresponds to z = -1.64, and
0.75 corresponds to z = 0.67
Now we put both of these into z-score formula and solve both equations for mu and sigma.
and
The first equation becomes:
Now, simplifying 2nd equation and putting this in:
Now finding mu:
These two MU(mean) and SIGMA(standard deviation) are the 2 parameters.
