Answer: 17297828288+516-5166617 = 17292662187
Step-by-step explanation:
Clarissa jumped 2 3/8 below the qualifying height, while Anika jumped 1 5/6 above.
To solve, note that Clarissa's is - 2 3/8, while Anika's is 1 5/6, and that Anika is more
Subtract
1 5/6 - (-2 3/8)
Change each into improper fraction
1 5/6 = 6/6 + 5/6 = 11/6
2 3/8 = 16/8 + 3/8 = 19/8
11/6 - (-19/8)
Note that two negatives = one positive
11/6 + 19/8
Find common denominators. In this case, use 24
11/6(4/4) = 44/24
19/8(3/3) = 57/24
Combine like terms
44/24 + 57/24 = 101/24
Simplify
101/24 = 4 5/24
4 5/24 inches is how much higher Anika's jump was compared to Clarissa's.
hope this helps
Answer:
2.4
Step-by-step explanation:
We have to find the mean first
Now we have to find deviations.
Note that the deviations are calculated by subtracting the mean from the value. The distance is always positive so the deviations will be positive
Value Deviation
2 2-4.5 = |-2.5| = 2.5
4 4-4.5 = |-0.5| = 0.5
7 7-4.5 = 2.5
2 2-4.5 = |-2.5| = 2.5
3 3-4.5 = |-1.5| = 1.5
7 7-4.5 = 2.5
9 9-4.5 = 4.5
3 3-4.5 = |-1.5| = 1.5
1 1-4.5 = |-3.5| = 3.5
7 7-4.5 = 2.5
The last step is to find the mean of deviations.
The mean absolute deviation of given data set is 2.4 ..
Yes you have the right answer
