I just need point tbh so thanks !!
Subtract 7.8 points by 4.8 and you get 3.4 !!
Answer:
$11.50. Each CD cost $11.50.
Step-by-step explanation:
When trying to determine how much each CD cost, we need to know our total cost, $57.50, and how many CDs were bought, 5.
Since 5 CDs cost $57.50, we can divide our total cost by the number of CDs purchased to find the cost of each CD. 57.50 / 5 = 11.50
Answer:
David took 16 oranges.
Step-by-step explanation:
We are given the following in the question:
Total number of oranges = 48
Oranges rotten =
Number of oranges rotten =
There were 16 rotten oranges.
Number of good oranges left =
These are equally divided among Ben and David.
Number of oranges each Ben and David get =
Thus, David took 16 oranges.
Answer:
2.6
Step-by-step explanation:
The Mean Absolute Deviation (MAD) is the average amount that each point is from the overall average of the data set.
So, first find the overall average (also called the mean):
avg = (1 + 1 + 2 + 3 + 5 + 7 + 9) / 7
= 28 / 7
= 4
The average (mean) is 4, so now you calculate how far each point is from 4 and average those numbers:
Note: Remember to use absolute values, since distance can't be negative.
4 - 1 = 3
4 - 1 = 3
4 - 2 = 2
4 - 3 = 1
4 - 5 = |-1| = 1
4 - 7 = |-3| = 3
4 - 9 = |-5| = 5
And finally, average (or find the mean) the new data set:
avg = (1 + 1 + 2 + 3 + 3 + 3 + 5) / 7
so 18 / 7 is the MAD of the data set.
Finally, round it to the nearest tenth:
18 ÷ 7 = 2.57142857143 ≈ 2.6
