Answer: 0.8490
Step-by-step explanation:
Given : The population of lengths of aluminum-coated steel sheets is normally distributed with a mean of 30.0 inches and a standard deviation of 0.9 inches.
i.e. and
Let x denotes the lengths of aluminum-coated steel sheets.
Required Formula :
For n= 36 , the probability that the average length of a sheet is between 29.82 and 30.27 inches long will be :-
∴ Required probability = 0.8490
The correct solution graph to the inequalities are
→ C
→ A
→ B
(NOTE: The graphs are labelled A, B and C from left to right)
For the first inequality,
First, clear the brackets,
Then, collect like terms
Now divide both sides by 12
∴
For the second inequality
First, clear the fraction by multiplying both sides by 3
Now, open the bracket
Collect like terms
Divide both sides by 6
∴
For the third inequality,
First, clear the brackets
Collect likes terms
Divide both sides by 1.6
∴
Let the graphs be A, B and C from left to right
The first graph (A) shows and this matches the 2nd inequality
The second graph (B) shows and this matches the 3rd inequality
The third graph (C) shows and this matches the 1st inequality
Hence, the correct solution graph to the inequalities are
→ C
→ A
→ B
