1 answer:
Answer:
Step-by-step explanation:
Given that the number of orders received daily by an online vendor of used CDs (say X) is normally distributed with mean 270 and standard deviation 16.
X is N(270, 16)
To find percentage of days will the company have to hire extra help or pay overtime, we can find probability using std normal table
X>302 means
P(Z>2) = 0.25
Thus 25% of days will the company have to hire extra help or pay overtime

As the expression is not equal to zero on x=3, x-3 is not a factor of given expression
Step-by-step explanation:
Given expression is:
We have to check if x-3 is a factor of given expression
In order for x-3 to be a factor of expression, we have to put x-3 = 0 => x=3 in expression.
If the expression is zero at x=3 then x-3 is a factor of expression otherwise not.
So putting x=333 in expression
As the expression is not equal to zero on x=3, x-3 is not a factor of given expression
