@spf924 I had the one sibling being more likely to run than both

But idk

i got like 3 diff from u yay

The questions based on the 95% confidence interval, the part 2 part of it, why didn’t they continue the new procedure? I said 1/10= 1% which is less than 5%

@spf924 I said as x approach -3 y approach minus infinity

I mean 1/100**

Who got 69 for number 26 lol

I got 69

@kimclan1 what did u get for the jogging kne

One

2 siblings was more likely because the proportion 1 sibling jogs was like .18 and for 2 siblings job was like .22

Agreed kimclan1

And I put the solution to the one with f(x)=g(x) because I figured solutions were always coordinates but I may be wrong and for the AC I didn’t put it over n

They were not coordinates. I know this because if they were then 3 and 4 were correct.

for the AC one it had to be over N in order to determine the cost per year. The function gave you the total cost, dividing by n would give cost per year
as for the f and g problem, we may just have to wait until a key comes out to determine that one.

Ok. Does anyone know the answer for sure for the spinner?

I could not be over n, it gave you the cost of 3 months per year and asked for yearly profits. You can confirm this by simply graphing it and you would see that you get a rational function.

It said average cost per year so it would be over n.
The answer for spinner I think is 3 (not unfair since 20% got 0) since it would be within the 95% interval.

@ss1231 it’s true it’s a rational function, but the piece of the function that you found was the total cost to run for n years. To find the cost per year (think of it like average) you had to divide by the number of years
For example: if you were trying to find out your average grade for the quarter, you’d add all your test grades, and divide by the number of tests to get the average
The piece about 3 months out of the year was irrelevant
