The final solution is y=-5/3x-10
Answer:
Mr. Roland’s class was more successful because his class’s lower quartile was the same as Mrs. Cai’s class’s upper quartile.
Step-by-step explanation:
From given scatter plot, we see that upper quartile of Mrs. Cai's class = 4
lower quartile of Mr. Roland’s class = 4
Both are equal so that means.
That means Mr. Roland’s class was more successful because his class’s lower quartile was the same as Mrs. Cai’s class’s upper quartile.
Hence last choice is correct.
Let x represent number of wrong questions answered by Aaron.
We have been given that Aaron is taking a multiple choice test with a total of 20 points available. Each question is worth exactly 1 point. We are asked to find Aaron's score (out of 20) if he got 6 questions wrong.
To find Aaron's score, we will subtract number of wrong answers from total score.



Therefore, Aaron's test scores would be 14 out of 20.
To find Aaron's score if he got x questions wrong, we will subtract x from total scores that is
.
Therefore, Aaron's score would be
, if he got x questions wrong.

Using the slope formula the answer would be 1-(-1)/(-1)-6. The slope would be 2/-7. It would be a negative slope.
