What is the MAD?
Group of answer choices
6.92 (in thousands of dollars) or $6,920
7.84 (in thousands of dollars) or $7,840
4.35 (in thousands of dollars) or $4,350
8.96 (in thousands of dollars) or $8,960
Answer:
Step-by-step explanation:
To calculate the Mean Absolute Deviation (MAD) for a set of data, follow these steps:
1. Find the mean (average) of the data set by adding up all the values and dividing by the total number of values. In this case, the sum of the values is:
85 + 91 + 93 + 99 + 99 + 99 + 102 + 108 + 110 + 115 = 1001
Dividing 1001 by 10 (the number of values) gives us the mean:
1001 / 10 = 100.1
2. Subtract the mean from each value in the data set and take the absolute value of the result. This gives us the deviation of each value from the mean. For example, the deviation of the first value (85) from the mean (100.1) is:
|85 - 100.1| = 15.1
Repeat this step for all the values in the data set.
3. Calculate the average of these deviations to find the Mean Absolute Deviation. Add up all the deviations and divide by the total number of values. In this case, the sum of the deviations is:
15.1 + 8.9 + 6.9 + 0.9 + 0.9 + 0.9 + 1.9 + 7.9 + 9.9 + 14.9 = 77.1
Dividing 77.1 by 10 (the number of values) gives us the Mean Absolute Deviation:
77.1 / 10 = 7.71
Therefore, the correct answer is not listed among the given options. The MAD for the given data set is approximately 7.71 (in thousands of dollars) or $7,710.

Answer:
24 cars
Step-by-step explanation:
By using 11 cars and AED 79.75, you can find out the cost of washing 1 car.
(AED 79.75)/(11 cars) = AED 7.25 / car
Now we divide AED 174 by AED 7.25/car to find the number of cars.
(AED 174) / [(AED 7.25)/car] = (174/7.25) cars = 24 cars
Answer: 24 cars
