Answer:
c) 62.
Step-by-step explanation:
Let x represent number of customers came in on the fifth day.
We have been given that the mean number of customers for those four days is 52. So total number of customers on 4 days would be 4 times 52 that is 208 customers.
We know that mean of a data set is equal to sum of all data points divided by number of data points.
Total number of customers on 5 days would be
and total number of days is 5.
Since we need a mean of 54, so we can set mean of 5 days equal to 54 as:

Multiply both sides by 5:




Therefore, 62 customers must come in on the fifth day to make the five-day mean 54 and option 'c' is the correct choice.
I believe the answer is C
Answer:
The number generator is fair. It picked the approximate percentage of red lollipops most of the time.
Step-by-step explanation:
The other answer choices represent various misinterpretations of the nature of the experiment or the meaning of the numbers generated.
___
A number generator can be quite fair, but give wildly varying percentages of red lollipops. Attached are the results of a series of nine (9) simulations of the type described in the problem statement. You can see that the symmetrical result shown in the problem statement is quite unusual. A number generator that gives results that are too ideal may not be sufficiently random.
Answer:
The answer is 100.5
.
Step-by-step explanation:
To solve for the volume of the cylinder, use the cylinder volume formula, which is V =
.
Next, plug in the information given from the problem, and the formula will look like V =
.
Then, solve the equation, and the answer will be 100.5
