sorry if is not the answer
Hi there!
Part A: Those groups of points that are circled and labeled A are called a correlation. In this case, the group of points represent negative correlation. The point that is labelled B is called an outlier, because it falls outside of the range of the other points. Point B may have been present like that, because while a person may spend a lot of time on social media, they might have understood the information very fast, or maybe they studied a bit on a different occasion.
Part B: Going back to part A, the graph represents a negative correlation. In this case, the more time spent on social media, the lower the test scores.

And,what is the question so that i can help u??
The value of the constant k when the value of x and y is 7 and 3 respectively in the equation xy=k is 21.
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The value of the constant k when the value of x and y is 7 and 3 respectively in the equation xy=k can be written as,
Hence, the value of the constant k when the value of x and y is 7 and 3 respectively in the equation xy=k is 21.

Answer:
The solution is 8=r
Step-by-step explanation:
When the question states, "What is the distance from the edge of the dart board to the exact center of the bullseye (to the nearest inch)," it is basically asking to find the radius rounded to the nearest whole number given the circumference quantity.
Thus, we need to substitute the numbers already given into the radius equation.
53.3=2 x 3.14 x r
Now, divide both sides by 3.14.
16.97=2r
Again, use division property of equality and divide both sides of the equation by 2.
8.4=r ... then rounding to the nearest inch... 8=r
All things said, the solution is 8=r
I hope this helped!!
