B:180 degrees because a circle is 360 degrees and half of 360 is 180. I'm learning this too lol
Answer:
x1=3 x2=-5
BUT x1=3 is not an answer because it doesnt respects the range on the original ecuation, so x2=-5 is the solution
Step-by-step explanation:
From the circle geometry theorem, a tangent to a circle makes 90° angles with the radius of the circle.
RQ is perpendicular to QP
Triangle RQP is a right-angled triangle
by Pythagoras theorem

units (rounded to one decimal place)
Answer:
The true mean
it probably could be larger, smaller, or equal to 22
Step-by-step explanation:
False.
By definition the sample mean is defined as:

For this case the value for the sample size is n =190 and the calculated sample mean is
. This value represent the sample and for this case we can't assume that this value represent at all the population as the population mean
since we probably have variability from the data of the students at City College.
So we can conclude that the true mean
it probably could be larger, smaller, or equal to 22
