And the one with the varies inversely 150 and 3 what was the answer
can someone explain why the sd wouldn’t change?? i thought it would decrease regardless of whether there’s and odd/even #
What was the spheres one was it all 3
Can someone please answer my question?
Towards the end of the test I had 4 blank. If I guessed C on each of the ones I left blank (I remember the last two questions I guessed C), would I be alright?
What about for the question on sin B? I put that you cannot determine the answer based on the information that they give you… You cannot prove that it was a right triangle, therefore it doesnt matter whether Sin A = 1/2? I put A at first, but then I changed it because i ddint think that it was right.
the absolute value question with tan= 20?
@elmstreetking I think so. That’s what I put
And also for the question about the two surface of sphere intersecting… Like or say if you got that it would make a point, circle, and sphere.
@luckykansasmath use law of sine
Yes!!!
Standard deviation means the average difference of a data point from the mean. You square and square root it so it’s not technically that, but still close enough. By adding a value that’s the same as the mean, the average difference from the mean is a bit smaller, and hence the standard deviation decreases.
It was 2 and 3
You split the triangle into two right triangles. I got 1/4 as an answer.
What was the two spheres question? I put that it could be both a point or a sphere.
@luckykansasmath it gave you enough info to use law of sines bc you had the sin of one angle and 2 side measures, including the one opp of the angle given
The saner for the pizza toppings was 92 right
@goldennuggets Yep, idk why more than 1/2 the people put stayed the same…
i put point and circle
My calculator can do Excel stuff so I quickly put down a series of numbers and when I added one the stdev decreased?
