Multiplicative Inverse of rational number:
When we multiply a rational number and its multiplicative inverse, we get 1

Now,multiply this with (3/-17)

So, -5 2/3 is the multiplicatice inverse of 3/-17
30/54 in simplest form is 5/9
Answer: a) 0.6141
b) 0.9772
Step-by-step explanation:
Given : Mean : 
Standard deviation : 
The formula for z -score :

a) Sample size = 1
For x= 63 in. ,

The p-value = 

Thus, the probability is approximately = 0.6141
b) Sample size = 47
For x= 63 ,

The p-value = 

Thus , the probability that they have a mean height less than 63 in =0.9772.
