Answer:
I THINK 96
Step-by-step explanation:
11x11=121
5x5=25
121-25=96
To find the range subtract from the biggest to the lowest, so it would be 86 - 13 which equals to 73.
Your lower or first quartile would be 42 and your upper or third quartile would be 74.
Hundredths: 8.98
Tenths: 9 whole
ones: 9 whole
tens: there is none
So to find percent error you want to take the estimated time minus the actual time or, 32 - 40. You get -8. Now take the absolute value of -8, or 8, and divide that by the actual time, 40. 8 ÷ 40 = 0.2. You want to take your decimal, 0.2, and multiply it by 100. 0.2 * 100 = 20. Finally, add the percent sign and you have your percent error: 20%
