Question

Estimate the following using clustering: 21.8 + 20.1 + 19.5 + 19.2 + 19.1 (Points : 1)
99.7
100
95
20

Answer 1

All numbers are clustering around 20.0

So how can you use that?

Answer 2

If each term can be approximated by 20 and you have 5 terms, what is the sum of this approximation?

Answer 3

i dont know sorry

Answer 4

so the answer will be 20

Answer 5

21.8 + 20.1 + 19.5 + 19.2 + 19.1=
(20+1.8)+(20+.1)+(20-.5)+(20-.8)+(20-.9)=
5*20 +(1.8+0.1-0.5-0.8-0.9)

Answer 6

99.7
