Mathematics
1 answer:
Katen [24]3 years ago
7 0

Answer:

7

Step-by-step explanation:

The external angle of a triangle is equal to the sum of the opposite interior angles

18x+9 = 5x-5 + 105

Combine like terms

18x+9 = 5x +100

Subtract 5x from each side

18x-5x +9 = 5x+100-5x

13x +9 = 100

Subtract 9 from each side

13x +9-9=100-9

13x= 91

Divide by 13

13x/13 = 91/13

x = 7

22. 48.6% of the North Dakota population over 18 years old is female.
Anna11 [10]

Answer:

32% probability that a randomly selected adult in North Dakota will be a female who has enrolled in college.

Step-by-step explanation:

We have these following probabilities:

48.6% probability that a randomly selected adult in North Dakota is a female.

If a randomly selected adult in North Dakota is over 18, 65.9% probability that they have enrolled in college at some point in their lives.

These events are independent.

This means that to find the probability that a randomly selected adult in North Dakota will be a female who has enrolled in college, we can just multiply these probabilities.

P = 0.486*0.659 = 0.32 = 32%

32% probability that a randomly selected adult in North Dakota will be a female who has enrolled in college.
