I'm not really the one to ask for help but...PLEASE HELP!!!
1. Rosa, Roberto, Andrea, and Inno find an estimate for 10 . Who has proposed the best
solution?
(1 point)
Rosa: “Use 9 and 25 to estimate.”
Roberto: “I will use 4 and 9 .”
Andrea: “It should be 11 and 12 .”
Inno: “Use 9 and 16 to find the estimate.”
To determine who proposed the best solution, we need to compare the estimates given by each person and see which one is the closest to 10.
Rosa proposed using 9 and 25 to estimate. We can find the average of these two numbers by adding them together and dividing by 2:
(9 + 25) / 2 = 34 / 2 = 17
Roberto proposed using 4 and 9 to estimate. Again, we find the average:
(4 + 9) / 2 = 13 / 2 = 6.5
Andrea proposed using 11 and 12 to estimate. Once again, we find the average:
(11 + 12) / 2 = 23 / 2 = 11.5
Inno proposed using 9 and 16 to estimate. Find the average:
(9 + 16) / 2 = 25 / 2 = 12.5
Now, let's compare these estimates to the number 10. We need to see which estimate is closest to 10:
- Rosa's estimate: 17
- Roberto's estimate: 6.5
- Andrea's estimate: 11.5
- Inno's estimate: 12.5
Out of these options, Andrea proposed the estimate of 11.5, which is the closest to 10. Therefore, Andrea has proposed the best solution.
