thats why i got 2x-3. I chose the x^2 one that was positive because it was x^2/x and that the top function would grow infinitely large with huge numbers while the bottom would remain small basically mirroring a quaratic. I think im wrong about that
What other answers do you guys remember?
Also just wondering, if you’ve taken any P/SAT math tests before what did you get on them? I got a 730/760 on the PSAT math section and a 760/800 on the normal SAT I math section
I got a 700 on the PSAT math and a 780 on the actual math portion of the SAT 1
Havent taken actual sat but I got a 35 on ACT math
That test was scary T^T
whats the best math 2 curve you guys have ever heard of ? Hahahaha
@sangrialeaf i skipped like 4 but i knew the answer for 2 of them after I finished. Everything seemed pretty doable
1/X was the only one correct for the symmetrical about origin, right?
Does anyone know what the curve will be?
What about the Standard Deviation question?
@Muhammad I said that it would get smaller because more numbers would bring the grouping in more.
Does the curve change every year?
@please122 how about the horizontal asymptote. It should be 3
@qwertyqwaf99 it should be the same. If the mean is 30, I can assume that everyone has to age of 30. If just another 30 year old man joins, the standard deviation doesn’t change. Did the question say anything about the first standard deviation?
Standard deviation decreases I tested in my calculator 4 different examples an even # of people w mean 30 an odd # of people with mean 30 and the same with an added person who is 30 all cases standard deviation decreased
It’s a circle and a point intersecting spheres are a set of points that when intersection only form 2 dimensional objects. If they were tangent that’s where the point would be. Circle is clear if you think about it one in front of the other draw a large circle and a smaller one the smaller is the intersection of the sphere the larger is the circumference of the sphere
I know. But, if people have all age of 30 and another person with age of 30 joins, the standard deviation doesnt change. When people have all age of 30, the mean is still 30.
You’re adding a term so the calculation is the sum of the square of the difference over n-1 since n increases then the standard deviation decreases
The square root of the entire expression sum of differences squared over n-1
