The best estimate for this correlation would be B) 0.9.
We can see that the number is constantly going up, which would throw out the D answer.
We can also see that for every time the x goes up 1, the y goes up a little less than one. We can see that in the ordered pairs that exist on the graph such as (3, 2), (8, 6) and (2.1, 1.9).
Since the y values are just lower than the x, the correlation would be just under one. Therefore, 0.9 is an accurate estimation.
The equation we use here is:

x is for the number of games he played on first day, y is the games on second day. The coefficients are the decimal form of percentages.
Simplify:

To find x we need to use the ratio. We have 85/100 as the first day's ratio and because the games needs to be whole, we can simplify this as 17/20. So in first day, he played at least 20 games and won 17 of them.
When we plug the 20 into the equation as x:

So he needs to play at least 30 games in order to get his score to 94%.
Answer:
25
Step-by-step explanation:
Here we are supposed to find the distance between two coordinates ( 4,10) and (-3,-14).
Let us do this step by step with detailed explanation.
We will use distance formula in order to find the distance between them. The distance formula is given as

Here we have

Replacing them in the formula we get

Hence our distance is 25 units
