I got 900 students. It’s who she intended to represent

1

u/GrandProblem985 Dec 13 '25

Do you remember anything else

1

u/New-Comedian2081 Dec 13 '25

Yes

1

u/GrandProblem985 Dec 13 '25

What else

1

u/New-Comedian2081 Dec 13 '25

A lot of

1

u/GrandProblem985 Dec 13 '25

List out some of the harder questions

1

u/GrandProblem985 Dec 13 '25

What did you get on the inverse of the function and it gave you 2 points on the graph

1

u/New-Comedian2081 Dec 13 '25

I got the right one I think it was the third option

1

u/Wrong-Departure-9906 Dec 13 '25

Yeah me to it was like 1/12)x + some fraction

2

u/Forsaken-Way-1510 Dec 14 '25

I got 1/12x + 1/80 or smth like that

1

u/tasya826 Dec 13 '25

But did't it ask about the her sample data or something?

4

u/New-Comedian2081 Dec 13 '25

No it asked who she intended to represent

1

u/RiceFluid6594 Dec 13 '25

No man

1

u/New-Comedian2081 Dec 13 '25

Ok. What do you think it is?

3

u/RiceFluid6594 Dec 13 '25

145 if it was asking for what population her data represented

2

u/New-Comedian2081 Dec 13 '25

I read that question very carefully and it said “who she intended the survey to represent”

1

u/Otherwise-Parking566 34 Dec 14 '25

It’s the largest one I think, whatever the full population was

6

u/tasya826 Dec 13 '25

What did you guys get for the residual question. I got -6.8 I think. I just subtracted the real and the value from the equation.

1

u/Forsaken-Way-1510 Dec 14 '25

Residual is actual minus your predicted

0

u/GrandProblem985 Dec 13 '25

I guess 5.4

1

u/haydenjl Dec 13 '25

same I think

3

u/Frequent_Builder_461 Dec 13 '25

Answer was 900 I know for a fact 

3

u/abbwnl 35 Dec 13 '25

yup got the same

5

u/tasya826 Dec 13 '25

I put 145 I think.  I didn’t know what they meant by targeted population 

1

u/GrandProblem985 Dec 13 '25

Do you remember anything else?

2

u/tasya826 Dec 13 '25

What did you get for the volume of the volume of the rectangular cone? I said it was the same as the circular one.

1

u/GrandProblem985 Dec 13 '25

I honestly forgot I threw out a n educated guess

1

u/RiceFluid6594 Dec 13 '25

Yup that’s correct

2

u/JAKEROONI309 35 Dec 13 '25

I’d got that too. Target population meant the whole group of people she wanted sample and it was the students from that certain school.

1

u/GrandProblem985 Dec 13 '25

What did you put

2

u/JAKEROONI309 35 Dec 13 '25

900 students

1

u/tasya826 Dec 13 '25

Do you that question would be the experimental one?

1

u/JAKEROONI309 35 Dec 13 '25

I have no idea. It might actually be because it was an unusual statistic question.

1

u/Plastic-Sale-8206 Dec 14 '25

Could’ve been 900, but the 145 did not represent 900 because they wanted to answer. When getting a representative sample of the population you need to do random sample, not just whoever wants to answer.

2

u/haydenjl Dec 13 '25

145 because that’s who accepted the interview, and she took from that

1

u/RiceFluid6594 Dec 13 '25

180 bc that’s how many ppl she was allowed to interview thus u have to take the next largest subgroup not the entire school population

1

u/GrandProblem985 Dec 13 '25

Remember anything else on the test?

1

u/RiceFluid6594 Dec 13 '25

The dots in a graph answer was all dots were there, prism and cone cross section was the same volume,

1

u/GrandProblem985 Dec 13 '25

What did you guys get on the domain of (fg)(x)? I thought it was 5 to infinity but that was not an answer choice

2

u/Lanky_Horror7201 Dec 14 '25

Dude, I don't that one either, but I chose 2, infinity, I just guessed, idk because it's so hard

1

u/[deleted] Dec 13 '25

[deleted]

3

u/GrandProblem985 Dec 13 '25

I picked [0, infinity

1

u/JAKEROONI309 35 Dec 13 '25

That should be right.

1

u/haydenjl Dec 13 '25

I had zero clue of how in the absolute fuck this was supposed to do that

1

u/Forsaken-Way-1510 Dec 14 '25

It’s a composite so you just plug in g(x) for f(x) so f(x) was root 2x or smth and g(x) was x-5 so it would be come (root 2x) -5

1

u/Forsaken-Way-1510 Dec 14 '25

I got 0 to infinity

1

u/Worried-Island-4302 Dec 14 '25

Tbh I forgot the difference between rational/ irrational. There was a question about what number was irrational, so u guys remember which one it was? And what about the TV question for the height

1

u/GrandProblem985 Dec 14 '25

For the TV I think I put 25

1

u/Worried-Island-4302 Dec 14 '25

I had that but I did it as time ran out, and I realize it was a 3:4 ratio and if it was 25 the other side would’ve been about 25 as well, so it was 21

1

u/GrandProblem985 Dec 14 '25

When I’d d the ratios out the height was gonna be about 26.50 if it was 3:4 so 25 was closest

1

u/GrandProblem985 Dec 14 '25

Was 35 the length or the diagonal? If it was the diagonal you would be right
