Let’s assume the following statements are true: Historically, 75% of the five-star football recruits in the nation go to univers

marishachu [46]

Given:
75% of the five-star football recruits in the nation go to universities in the three most competitive athletic conferences. → 25% goes to other schools.

five-star recruits get full football scholarships 93% of the time, regardless of which conference they go to. → 7% of the 5-star recruits don't get full football scholarships.

a. The probability that a randomly selected five-star recruit who chooses one of the best three conferences will be offered a full football scholarship?
75% * 93% = 69.75%

b. What are the odds a randomly selected five-star recruit will not select a university from one of the three best conferences?
25% of selected five-star recruit will not select a university from one of the three best conferences. I got the number based on the given data. Since, 75% will go, the remaining percent won't go. Total percentage should be 100% of the population.

c. Explain whether these are independent or dependent events. Are they Inclusive or exclusive?
These are independent events. One can still go to different school and still be legible for the full football scholarship.

For question 2, pls. see attachment.

The measures of two angles of pairs of triangles are given. Which pairs of triangles are similar?

morpeh [17]

If the triangles are similar then the angles in both are equal. Let's look at each set individually:

(1) Triangle 1: 25°, 35°
Triangle 2: 25°, 120°
Now it may be hard to tell if the triangles are similar at the moment so we must calculate the third angle in each triangle (The angles in a triangle add up to 180°, therefor the missing angle = 180 - (given angle 1 + given angle 2)
Triangle 1: 180 - (25 + 35) = 120°
Triangle 2: 180 - (25 + 120) = 35°

Now writing out the set of angles again we have:
Triangle 1: 25°, 35°, 120°
Triangle 2: 25°, 120°, 35°

So in fact Triangle 1 and 2 are similar.

Now we can repeat this process for (2) - (5):

(2) Triangle 1: 100°, 60°, 20°
Triangle 2: 100°, 20°, 60°
This pair is also similar

(3) Triangle 1: 90°, 45°, 45°
Triangle 2: 45°, 40°, 95°
This pair is not similar

(4) Triangle 1: 37°, 63°, 80°
Triangle 2: 63°, 107°, 10°
This pair is not similar

(5) Triangle 1: 90°, 20°, 70°
Triangle 2: 20°, 90°, 70°
This pair is similar

Therefor pairs (1), (2) and (5) are similar

A news paper article reports the results of an election between candidates the article says that smith received 60% of the votes

Leokris [45]

If you want some help here, I can tell you!

60% is 60%, since the best way to find out is by converting the two numbers into percents.

You need to find out a decimal first for the second number in order to convert it to a percent. To find a decimal out of a fraction, you put the numerator in the house (I forgot what it was called) and then you put the denominator out. You divide, and you find that 1/3 is actually a repeating decimal, 0.33333333 and so on. You round to 0.34, and that's 34% since 0.34 is 34 out of 100, basically. 34% plus 60% is NOT 100%, and 100% is a whole, so that's why it isn't accurate.
