The box plot summarizes the number of people enrolling in fitness classes each month during one year at the city gym. The mean o
f the data is 163.75, and the mean absolute deviated (MAD) of the data is 65. In January of the next year, 400 people enroll in fitness classes at the gym. How does the MAD change if the data include January’s enrollment? Use the drop-down menus to explain. Click the arrows to choose an answer from each menu. A MAD of 65 means that the monthly enrollment counts were an average of 65 from the (CHOOSE). An enrollment of 400 has a deviated value that is (CHOOSE) the MAD. The data will have (CHOOSE) variability when January’s enrollment is included. This will result in a new MAD that is (CHOOSE) 65.

The error rate has decreased after changing the painting process.
<u>Step-by-step explanation:</u>
Abdulla knows that 20 percent of the parts have an error in their painting. After suggesting changes in painting process, he wants to know whether the error rate has changed.
Number of parts in the random sample=400400400
Number of parts that had an error=606060
We have to determine what percentage of 400400400 is 606060
After changing the painting process 0.15% of parts have error.
The previous percentage was 20.Hence the error rate has clearly changed.
Answer:
The new rate should be $56.67 per day
Step-by-step explanation:
Proportion states that the two fractions or ratios are equal.
As per the statement:
Normal rate per day = $45
To find the new rate:
Let new rate be x per day
By definition of proportion:
By cross multiply we have;
Divide both sides by 100 we get;
Simplify:
x = $56.7
Therefore, the new rate should be $56.7 per day
Answer:
ft/min is the rate of changing of width
Step-by-step explanation:
Given -
The area always remain constant i.2 2 square feet.
Height of the rectangle = 2 feet
Rate of changing of height = 6 feet per minute
Since area is constant
2 sq ft = (2 * 6) ft/min * 1 * x ft/min
x = ft/min
