Answer:
-4.88692
Step-by-step explanation:
1) You included neihter what Ramesh says nor the statements, then I can you tell some facts about the pattern.
2) The sequence is: 2401, 343, 49, 7, and 1.
3) The first term is 2401
4) The sequence is a decreasing geometric one.
5) The ratio is found dividing two consecutive terms (the second by the first, or the third by the second, or the fourth by the third, or the fifth by fourth):
1/7 = 7 / 49 = 49 / 343 = 343 / 2401.
So, the ratio is 1/7
6) The sum of that sequence is 2401 + 343 + 49 + 7 + 1 = 2801
Given:
8 tasks
5/6 hours total
Unit rate per task:
5/6 hours ÷ 8 tasks = 5/6 * 1/8 = 5/48 or 0.10 hours per task
0.10 hours x 60 minutes/hour = 6 minutes per task.
Unit rate per hour:
8 tasks ÷ 5/6 hours = 8 * 6/5 = 48/5 = 9.60 tasks per hour or rounded to 10 tasks per hour.
The answer is Y=-11 after you plug in -4 for x
