Answer:
correct anwer=27
Step-by-step explanation:
the anwer for this equation comes out to be 27. As simple as it becomes on applying paranthesis to this equation therefore we get
8+(30/2)+4=27
we need to apply the paranthesis using the method of BODMAS.
which favours division over addition.
therefore,correct anwer is 27 and not 13
Answer: (C) 0.1591
Step-by-step explanation:
Given : A manufacturer of radial tires for automobiles has extensive data to support the fact that the lifetime of their tires follows a normal distribution with


Let x be the random variable that represents the lifetime of the tires .
z-score : 
For x= 44,500 miles

For x= 48,000 miles

Using the standard normal distribution table , we have
The p-value : 

Hence, the probability that a randomly selected tire will have a lifetime of between 44,500 miles and 48,000 miles = 0.1591
