@ss1231 I agree, plus if you graphed both the one over n would decrease as the years, or n, increased, which wouldn’t make much sense
For the spinner, i picked it is likely NOT unfair, as 6 failed to show up in about 20% of the cases. I’m fairly certain that’s the right answer
I got NOT unfair as well for the spinner but I chose 4 as the reasoning, uh oh
What did u guys get for the cubed root of x times the square root of x
I got x 5/6 but I don’t know
X^5/6
Yeah that’s what I thought
For the AC one was it 3 or 4 becuz both had over n
Is it me or was the short answers on this test fairly easy it was just the multiple choice that got a bit tricky
It was x^5/6
Change the cube root of x to x^1/3, and square root of x to x^1/2. Get exponents to common denominator (2/6 and 3/6) and add them
What did you guys put for 100(1.039)^x? The one about since 2010 the population of NYC and it gave 2 options?
Option 2 only I think
I just chose choice 2, because it was 3.94, which is about 3.9% but today meant 2017 so 1 had to be wrong
Option 2 was correct
Does anyone know if the answers got leaked. Last year the geometry got leaked at 6
I said neither:
Assuming that today is 2017, the population today obviously is not 100
Also, the probably actually something like 100e^(.03922x) so this can be written as 100(1.0399)^x, which means that technically it is not 3.9% approximately but rather 4.0%. The answer may be 2 (the 3.9% only) but I think that it is approximately 4.0%.
It would be “algebraically” if I solved the system of equations using row operations… right?
Was the probabitly of jogging a 2 credit or 4 credit question?? What number was it? My remembrance was 32 but I’m not sure
Yes. You could use matrices or just keep multiplying each equation by various constants to eliminate variables. I believe I got x=0 y=2 and z=-1 or something
I do not believe you could solely graph it either since you would need to use a 3d graph and see where planes intersect lol. I was a bit mad of how they had logarithm in base 2 for one of the part 3 because with a ti-83 you cannot just type in a logarithm of another base and would have to type in something like y=(ln(x+3))/(ln(2)-5
