Answer:
Required probability is 0.9748
Step-by-step explanation:
given data
mean 
= 117.7-cm
standard deviation 
= 2.2-cm
sample size n = 29
solution
we consider here random variable which represents here length of rod= x
so get here first z that is express as
put here value with x value 118.5-cm
Z = 1.9582
p value is 0.9748
so required probability is 0.9748

Answer;-1.5238095238
First step; 8/15
8/15 = 0.53 and so on in a repeating form. (0.53333333333)
Divide; 0.53 / -0.35
= -1.5238095238
13 - (x+2) = 8
subtract 13 from both sides
-(x+2) = -5
divide by -1 to get rid of negative
(x+2) = 5
subtract 2 from both sides
x=3
