Answer:
<u>The French restaurant did not use cream this year, due to a menu update.</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Amount of cream used by a French restaurant last year = 92.870 ounces
Amount of cream used by the French restaurant this year = 100% less
2. How much cream did the restaurant use this year?
The answer is zero and we calculated it this way:
92,870 - 100% (92,870) = 92,870 - 92,870 * 1 = 92,870 - 92,870 = 0
<u>The French restaurant did not use cream this year, due to a menu update.</u>
20x(5/100)=1
That is the interest after one year
Add to the principal:20+1=21
Let's come up with variables to substitute and make an equation.
T = total number of minutes
P = number of minutes used by each person in the phone plan
R = remaining minutes per month
R=T-3P
Now that we have an equation, we can substitute the numbers we are given in the problem to find the final solution.
R= 675- 3(250)
R= 675- 750
R= -75 minutes
There are no remaining minutes, and in fact, the people on the phone plan have used 75 extra minutes than provided for in their phone plan.
The probability that a randomly selected customer takes more than 10 minutes will be 8.38%
<em><u>Explanation</u></em>
The average or mean
is 8.56 minutes and standard deviation
is 1.04 minutes.
<u>Formula for finding the z-score</u> is: 
So, the z-score for
10 minutes will be.....

Now, according to the standard normal distribution table,
. So.....

So, the probability that a randomly selected customer takes more than 10 minutes will be 8.38%
