Quadrant 2 contains the vertex of f(x)=-2x^2-8x+11
Answer:
i don't know, you need to tell us what we need to do
Step-by-step explanation:
Problem 1) Line n is the line of symmetry (not line o) because we can fold the lower half to match up with the upper half. The folding line is over line n.
Problem 2) I agree. Nice work on getting the correct answer. The folding line is a vertical line through the center
Problem 3) It's hard to say for sure, but I think the top left corner is NOT reflective over any line of symmetry no matter how you rotate it. So I would uncheck that box. I agree with your other choices though. Great job with those.
Answer:
And rounded up we have that n=1068
Step-by-step explanation:
We have the following info given:
the confidence level desired
represent the margin of error desired
The margin of error for the proportion interval is given by this formula:
(a)
The confidence level is 95% or 0.95, the significance is
and the critical value for this case using the normal standard distribution would be 
Since we don't have prior information we can use
as an unbiased estimator
Also we know that
and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
And replacing into equation (b) the values from part a we got:
And rounded up we have that n=1068
Answer:
It has an infinite amount as the decimal keeps going to over 1 million digits and beyond.
