Thank you. Appreciated.
Can someone explain the last problem?
I quote myself: any idea on whether the curve may be harsh or lenient? Thanks.
what was the last problem
@potterismylife it was the one about maximum population… i chose c, January every other odd year
@Hope4567 if you graph the given model, then 2nd->Calc for each answer choice you arrive at January every odd year
yeah that’s what I did, the first max was 12 and the first min was 36, so starting from 1990 after one year it hit a max in jan (1991)
what did everyone get for the “for which of these 3 tables is y a function of x” question?
@hsgirl1226 no it’s definitely E. It’s the 10xh+5h^2-2 or something choice
Just do vertical line test
I said all of them bc each x only had one value of y
It was 2 and 3 only cause the first one had two X values of 0 with different y values so it failed the vertical line test.
ah, didn’t notice the double x on the first table
a function is anything that passes the vertical line test
a horizontal line does so it is a function
the first one had two y values at zero so it wasn’t 1
ughhh I missed that double x
polar question I also got (2, 3pi/2)
@soporificpeafowl I put that too. what was D?
@jahnbrown I think it was a graph but everything on the graph was below the x axis
(1, 7pi/4) why would this work?
For the standard deviation = 0 question, did you guys get the graph where every student received a score of 80?
