Answer: 9 meters</h3>
===========================================
Work Shown:
- side a = 8
- side b = 5
- angle C = 88 degrees
Applying the law of cosines
c^2 = a^2 + b^2 - 2*a*b*cos(C)
c^2 = 8^2 + 5^2 - 2*8*5*cos(88)
c^2 = 64 + 25 - 80*cos(88)
c^2 = 86.2080403
c = sqrt(86.2080403)
c = 9.2848285
c = 9
Technically he needs 10 meters of rope because of the extra 0.28 portion, but I'll stick with 9 meters since your teacher said to round to the nearest whole number.
To do this problem, add up all the numbers and divide by the amount of numbers:
1.01+1.03+.98+.99+1.01+1.02+.98+1.05+.97+.98
10.02
Now divide by 10 (the amount of samples)
10.02/10
1.002
The Mean of the Data Set is 1.002
Hope this helps!
