The correlation coefficient represents a moderate negative correlation is -0.64.
<h2>We have to determine</h2>
Which correlation coefficient represents a moderate negative correlation?
<h3>According to the question</h3>
The correlation coefficient is a measure of the strength of the linear relationship between two variables and is denoted by r.
The values between 0.3 and 0.7 indicate a moderate positive (negative) linear relationship.
The values between -0.3 and -0.7 indicate a moderate negative linear relationship.
The only value of r in the option is r= -0.64 lies in a given interval of the moderate negative linear relationship.
Hence, the correlation coefficient represents a moderate negative correlation is -0.64.

<u>Given expression:</u>
To simplify the expression, we can apply the following rule: 
. This is known as the Quotient of Powers Property, which states that when dividing two powers with the same base, the exponents are subtracted.

For every 140 miles, Trey uses 4 gallons:
140:4
We can simplify this ratio to 1 gallon by dividing each side by 4
35 miles : 1 gallon
1) To find out the miles travelled in 6 gallons, we multiply ea b side by 6
35*6 = 210miles : 1*6 = 6gallons
So it is false.
2) For 5 gallons, we multiply each side by 5
35*5 = 175miles : 1*5 = 5gallons
Once again, it is false
3) We modify the ratio for price
35 miles : 1 gallon
35 miles : 3.45 dollars
And then we work in reverse - instead of multiplying the ratio to reach a certain number, we divide a certain number by the ratio
$27.6/3.45 = 8
For the question to be true, each side has to become
260 miles : 27.6 dollars when multiplied by 8
However, 35*8 = 280, not 260, so the statement is false.
