(x)(x)= x^2
(-8)(x)= -8x
(x)(1)= 1x
So, (-8)(1)=8
A+b=32
a-b=8
let's subtract bottom equation from the top:
a+b-(a-b)=32-8
2b=24
b=12
Then a=20
This statement in the article is wrong because $2.69 is not the mean price ($2.81)
<h3>How to determine what is wrong with the data?</h3>
The prices from 5 gas stations surveyed are given as:
$2.79, $2.99, $2.69, $2.89, and $2.69.
There are no outliers in the dataset
So, the dataset can be summarized by the mean
The mean is
Mean = Sum/Count
So, we have
Mean = ($2.79+ $2.99+ $2.69+ $2.89+$2.69)/5
Evaluate
Mean = 2.81
The article quoted $2.69 as the typical price
This statement in the article is wrong because $2.69 is not the mean price ($2.81)
