Answer:

B.  0.9

Step-by-step explanation:

Since here as the value of X axis is get increased, the value of Y axis is also increasing.

Thus, here Positive correlation is exist.

Also the slope of line is slant.

Slope is not near to horizontal, thus Correlation Coefficient will be greater than 0.5

Also, by the point we see here that the value of X is more get increased as compare to value of Y. So 1 is also not possible.

Hence the correlation coefficient for the given scatter plot is 0.9

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.

Vika [28.1K]

Answer: He had 14 more touchdowns than he did fumbles.

Step-by-step explanation:

Step 1. Ok, so we need to see how many times 9 will divide into 18.

18/9=2.

Step 2. So now that we know that 9 goes into 18 two times and we know he has two fumbles for every 9 touchdowns we can multiply 2 by 2 to find out how man fumbles he had.

2*2=4

Step 3. Now to find out how many more touchdowns than fumbles he had we need to subtract his fumbles from his touchdowns.

18-4= 14. So, now we know he had 14 more touchdowns than he did fumbles.

Hope this helps!
