7^2 x 3.14 = 154 inches^2
Answer: D) The linear model shows a strong fit to the data
The actual strength of the relationship is unknown unless we have the actual values of each data point (so we can compute the correlation coefficient r), but the residuals are randomly scattered about both above and below the horizontal axis. This means we have a fairly good linear fit. If all of the points were above the line, or all below the line, or all residuals fit a certain pattern (eg: parabola), then it wouldn't be a good linear fit.

the probability of the event choosing a yellow marble is 2/9 .
<u>Step-by-step explanation:</u>
Here we have , to choose a marble from a jar. The jar contains 4 red
marbles, 10 blue marbles, 7 green marbles, and 6 yellow marbles. We need to Find the probability of the event choosing a yellow marble . Let's find out:
According to question question we have following parameters as :
Red marbles = 4
Blue marbles =10
Green marbles = 7
Yellow marbles = 6
Now , Probability to chose a yellow marble is :
Favorable outcomes = 6(Number of yellow marbles )
Total outcomes = 4+10+7+6 = 27( Total marbles )
Hence ,
⇒ 
⇒ 
Therefore , the probability of the event choosing a yellow marble is 2/9 .
