Answer: option d.
Step-by-step explanation:
You have the following formul given in the problem:
You know that:
The number of customers serviced in an hour by the technical support representative is 6 costumbers, therefore:
As the problem asked for the probability that a costumber will be on hold less than 30 minutes, we know that:
Substitute the values above into the formula.
Then, you obtain:
or 95%
It is equal to 21/2 which is a rational number

</span>The restaurant is making 22 ¾ cups of chowder.
Each cup of chowder holds 7/8 of a cup.
Then the restaurant charges 2.95 dollars per bowl. Let’s find out how much
money will the restaurant earned.
Solutions:
=> 22 ¾ = 22.75 cups of chowder
=> 7/8 = 0.88 cup of chowder it can holds.
Let’s solve to get the correct answer:
=> 22.75 / .88 = 25.85 cups in all.
Then, let’s multiply this with the amount
=> 25.85 * 2.95 = 76.26 dollars.
SO the restaurant earned 76.26 dollars for the chowder.</span>
The greatest common factor of the two terms is 33a^3.
With the numbers 66 and 99, the greatest common factor is 33. It is the largest number that divides evenly into both.
For the variables, the most that is in common in both is a^3.
