Answer:
True
Step-by-step explanation:
The answer is B.
complementary means adding upto 90 degrees, but they dont unless they're both 45 degrees, so its not A.
they are not supplementary because that means they add up to 180 degrees and they dont unless theyre both 90 degrees, so its not C.
there IS a relationship between the measures of corresponding angles, so its not D.
the relationship between them is that they are always the same, so the answer is B.
I the average score is 750 and standard deviation ( sigma ) is 50 points, then score 700 - 800 is between (750 - 1 sigma) and (750 + 1 sigma).
That is 34.1 % + 34.1 % = 68.2 % of the whole population.
2,000 · 0.682 = 1.364
We expect 1,364 students to score between 700 and 800 points.
P(s) = 45/125 = 0.360
P(A&C) = 38/125 = 0.304
Probability that one is not in Arts and Crafts = 1- P(A&C) = 1-0.304 = 0.696
Therefore,
Probability that the child selected is in swimming when its known they didn't sign for Arts and craft = Probability they signed for swimming * Probability that they didn't sign for Arts and Crafts = 0.360*0.696 = 0.25056
