The variable 'T' equals -20.
Cheryl drove at a speed of 65 mph for 1 minute, drove at a constant speed for 5.5 minutes, and then drove at a speed of 45 mph for 2.5 minutes.Option C is correct.
<h3>What is a graph?</h3>
A diagram depicting the relationship between two or more variables, each measured along with one of a pair of axes at right angles.
Cheryl traveled at a steady pace for 5.5 minutes, then 45 mph for 2.5 minutes after traveling at 65 mph for a minute.
Statement C best describes Cheryl's commute.
Hence option C is correct.

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.
