Looks like 14.4 because you have to add them all together and divide by the total numbers
(20+22+10+5+15)/ 5

Answer:
- $52
- this estimate is a little low
Explanation:
a) I might choose 6 1/2 hours and $8 per hour, so the estimated earnings would be ...
6(8) +(1/2)(8) = 52 dollars . . . . estimated earnings
These values are purposely chosen so that one is a little high and the other is a little low, hopefully producing a closer estimate than if both numbers were high (as 7 hours, $8, for example).

b) Using 800 instead of 790 means the pay estimate is about 1/80 = 1.25% high.
Using 6 1/2 instead of 6 3/4 means the hours estimate is about 1/27 ≈ 3.7% low.
So, we expect the product of these values to be slightly low, perhaps by about 2.5%.

<em>Comment on estimating</em>
If you can estimate the error in the estimate with some reasonable accuracy, you can use that to adjust the estimate to a pretty close value.
CO = AO = 32 (Are rays.)
BO = BC + CO = 98 + 32 = 130
AB ⊥ BO
⇒ ΔAOB is a rectangular triangle.
We use Pitagora's theorem.
Given:
Consider the given expression is
To find:
The simplified form of the given expression.
Solution:
We have,
It can be written as
![[\because \log_ax+\log_ay=log_a(xy)]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Clog_ax%2B%5Clog_ay%3Dlog_a%28xy%29%5D)
![[\because \log_ax-\log_ay=log_a\dfrac{x}{y}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Clog_ax-%5Clog_ay%3Dlog_a%5Cdfrac%7Bx%7D%7By%7D%5D)
Therefore, the simplified form of the given expression is 
.
