Answer: 127 cookies

Step-by-step explanation:

1. If you look back to the text you will see that 12 is 1 in 1:3:4 and you multiply that by 2. 12 * 2 = 24.

2. Divide 24 by 3 and that gives you 8 than times it by 5 for it to give you 40

3. Divide 36 by 4 and that equals to 9 than multiply it by 7 which that gives you 63

4. Add 24, 40, and 63 for it to give you 127

Thank you for following these steps if it is correct and this is my first time so if I am incorrect I will look upon my mistake and correct and help many of you people who need help

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.
