Answer:
- The means for both data sets are equal.
- The range of the number of pages Lionel read is greater than the range of the number of pages Aaron read.
- The range of the number of pages that Lionel read is 75.
Step-by-step explanation:
Given
Lionel
90, 45, 30, 25, 15
Aaron
55, 19, 40, 16, 75
in the first case; For Lionel;
Mean = (90+45+30+25+15
)/5 = 41 and
Range = (90-15)=75
The second case; Aaron
Mean = (55+19+40+16+75)/5 = 41 and
Range = (75-16)= 59
Therefore;
Both data sets have the same mean but different range.
The range of the number of pages Lionel is 75, which is greater than the range of the number of pages Aaron read, which is 59.
Absolute deviation is 92.40
Rearrange numbers from least to greatest to avoid confusion.
108, 112, 122, 145, 160
Mean = (108 + 112 + 122 + 145 + 160) / 5
= 647 / 5
= 129.40
Absolute deviation : (number - mean)
*absolute means that a number is always treated as a positive number contrary to its actual value
108 - 129.40 = 21.40
112 - 129.40 = 17.40
122 - 129.40 = 7.40
145 - 129.40 = 15.60
160 - 129.40 = <u> 30.60</u>
total absolute deviation 92.40
Mean absolute deviation = 92.40 / 5 = 18.48
Bernardo travels the same distance at 25mph as he does at 50mph. However, since 25mph is only half of 50 mph, he must travel twice as long at 25mph. If you call the time he traveled 50mph "t", then
<span>t+2t=3 </span>
<span>3t=3 </span>
<span>t=1 </span>
<span>This means he traveled 1 hour at 50mph. In this time, he traveled 50 miles. He traveled the same distance at 25mph, so his total distance was </span>
<span>50miles+50miles=100miles </span>
<span>so the round trip was 100 miles.</span>

√136 ≈ 11.66
Therefore, the two whole numbers where 11.66 will be located in between are 11 and 12.
