I honestly didn’t think it was that bad but I was stressing over the stupidest question. What the one ab the TV shows a combination or permutation?

3

4

I put permutations and multiplication, because it said “number of different ways”. I’m wondering too though

5

What was the answer to the question that talked about students and their scores?

6

I got 5.27 for standard deviation, then 17 students for the next part

7

How many triangles did you get for the short answer response? What did you also get for the product of the roots?

8

1 triangle and k/3 I believe

9

1 triangle and k/3

10

Also I got 5.17 for the standard deviation and 21 students? Idk I was confused with the rounding

11

I got 5.17 and 21 students as well…

12

Does anyone remember the answer for last multiple choice? It had something to do with the 2015 and 2010?

13

Also: What was the answer for the multiple choice that asked for the inverse of the log?

14

I think 68 or something like that

15

27 was 49

the tv one was a combination
the log was 4^x

16

Do you remember which answer choice was 27? Which choice was 49?

17

Can someone please explain how they found the standard deviation for the short answer response that talked about the students and their score? I found that the deviation was 5.17, which would make the answer be 21 students. However, some people are saying that is was 5.27? What is right?

18

For the part 4 I got 66.4 180 and 293.6

19

Can someone also explain the question that had to do with subtracting the x,y, and i. I got that it was -xy. But I’m not sure??

20

5.27 is right because it asked for the population deviation not just the standard
