Answer:

100 degrees

Step-by-step explanation:

The three angles inside a triangle always add up to 180

so, 180-43-57 is 80

But that's the angle inside the triangle. notice that that angle (ACD) and BCA make a straight line.  That means they add up to 180. Therefore, 180-80=100 degrees.

What does X equal? 14x+24=18x-32
exis [7]

Answer:

x =14

Step-by-step explanation:

14x+24=18x-32

Subtract 14x from each side

14x-14x+24=18x-14x-32

24 = 4x -32

Add 32 from each side

24+32=4x-32+32

56 = 4x

Divide each side by 4

56/4 = 4x/4

14=x

Answer:

0.0803 = 8.03% probability that the number who have a high school degree as their highest educational level is exactly 32.

Step-by-step explanation:

For each adult, there are only two possible outcomes. Either they have a high school degree as their highest educational level, or they do not. The probability of an adult having it is independent of any other adult. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

30.4% of U.S. adults 25 years old or older have a high school degree as their highest educational level.

This means that p = 0.304

100 such adults

This means that n = 100

Determine the probability that the number who have a high school degree as their highest educational level is a. Exactly 32

This is P(X = 32).

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 32) = C_{100,32}.(0.304)^{32}.(0.696)^{68} = 0.0803

0.0803 = 8.03% probability that the number who have a high school degree as their highest educational level is exactly 32.
