Answer:
Step-by-step explanation:
ok for the first one
the angle measurement of AE which is a straight line is 180
and the Angle measurement of ABC is 50 and because of vertical angles i know that the measurement of FBE is also 50 so all you do it
180 - 50 = 130
so you answer is C

now for the second one
it would be The corresponding angles Theorem which is option A

Answer:
A function is going to be a line graphed on a coordinate plane. It has 1 or more variables. A function can be a straight line, a parabola, etc. however a function cannot have a repeating x-value.
Answer:
Probability that the sample mean score is less than 522 = 0.0166 .
Step-by-step explanation:
We are given that in 2010 the mean mathematics SAT score was 555, and the standard deviation was 125 i.e.;
Mean,
= 555 and Standard deviation,
= 125
Also, Z =
~ N(0,1) where, X bar = sample mean
n = sample size
Now, Probability(X bar < 522) = P(
<
) = P(Z < -2.1284)
= P(Z > 2.1284) = 0.0166
The above probability is calculated using z table.
Therefore, the probability that the sample mean score is less than 522 is 0.0166 .
