Answer:

m = 70°, n = 55°, p = 25°

Step-by-step explanation:

Start of with the 25 degree angle. It and angle p are vertical angles, and vertical angles are equal to each other. Now that we know the value of p we can solve for n. The 100° angle, n, and p are supplementary angles, meaning their total value equals 180 degrees. By subtracting p and 100 from 180, we get the value for n.

To find m, observe that the 110 degree angle and m also are supplementary angles. Simply subtract 110 from 180 to get the answer.

Suppose that 62 percent of the graduates from your high school go on to four-year colleges, 15 percent go on to two-year college

inn [45]

Answer:

b) .474

Step-by-step explanation:

If 62% go to a four-year college, that means that those who don't represent 38% of the high-school graduates.

You pick up someone who is NOT going to a four-year college (so, he's among the 38%)... what's the chance he's in the 18% of the whole high-school graduates population that found a job?

To calculate that probability, we have to divide 18% by 38%.

P = 18% / 38% = 0.4736, so 0.474

Since we are sure he doesn't go to a four-year college, there's 47.4% of chances he finds a job.

Miriam is picking out some movies to rent, and she is primarily interested in comedies and foreign films. She has narrowed down

Keith_Richards [23]

Answer:

There are 795 combinations.

Step-by-step explanation:

The number of ways or combinations in which we can select k element from a group of n elements is given by:

$nCk=\frac{n!}{k!(n-k)!}$

So, if Miriam want to choose 3 movies with at least two comedies, she have two options: Choose 2 comedies and 1 foreign film or choose 3 comedies.

Then, the number of combinations for every case are:

1. Choose 2 Comedies from the 10 and choose 1 foreign film from 15. This is calculated as:

$10C2*15C1=\frac{10!}{2!(10-8)!}*\frac{15}{1!(15-14)!}$

$10C2*15C1=675$

2. Choose 3 Comedies from the 10. This is calculated as:

$10C3=\frac{10!}{3!(10-3)!}=120$

Therefore, there are 795 combinations and it is calculated as:

675 + 120 = 795

8d + 1 = 5d + 10 can someone please explain how to solve this?

spayn [35]

Add '-1' to each side of the equation. 1 + -1 + 3d = 10 + -1 Combine like terms: 1 + -1 = 0 0 + 3d = 10 + -1 3d = 10 + -1

Combine like terms: 10 + -1 = 9 3d = 9

Divide each side by '3'. d = 3 Simplifying
