Yea something is not right.if y=6 then you cant solve the system because you end up with x^2-4x-1
Answer:
The rate of sales tax is 6%.
Step-by-step explanation:
First you must subtract 12.50 from 13.25
This brings you to .75
Then, divide .75/12.50 to get 0.06 which is equivalent to 6 percent.

<h2>Answer</h2>
<u>Strong, negative correlation.</u>
<h2>Explanation</h2>
So with correlations, they have two categories that they fall under.
Firstly, they either fall under <u>positive</u> or <u>negative</u> correlation. It's as it seems: positive correlation coefficients are positive numbers, negative correlation coefficients are negative numbers. In this case, our correlation is <u>negative</u>.
Next, they either fall under <u>weak</u> or <u>strong</u> correlation. If the absolute value of the correlation coefficient is closer to zero, then it's considered a weak correlation. However, if the absolute value of the correlation coefficient is closer to one, then it's considered a strong correlation. In this case, the absolute value of -0.91 is 0.91, and since that is closer to 1 this means our correlation is <u>strong</u>.
