Answer:

60 degrees

Step-by-step explanation:

If each side of the triangle WRD is 3 inches long, then WRD is an equilateral triangle, meaning all angles are the same size. Since there are 180 degrees in a triangle, 180/3 = 60 degrees.

jenyasd209 [6]

Answer:

y+6=\frac{-4}{3}(x-6)

Step-by-step explanation:

Slope intercept form is y-y1=m(x-x1).

A city council consists of eight Democrats and eight Republicans. If a committee of six people is selected, find the probability
saw5 [17]

Answer:

39.16% probability of selecting three Democrats and three Republicans

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question, the order in which the people are selected is not important. So we use the combinations formula to solve this question.

Combinations formula:

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)!}

Desired outcomes:

3 Democrats, from a set of 8.

3 Republicans, from a set of 8.

D = C_{8,3}*C_{8,3} = (C_{8,3})^{2} = (\frac{8!}{3!5!})^{2} = 56^2 = 3136

Total outcomes:

6 people from a set of 16.

T = \frac{16!}{6!10!} = 8008

Probability:

p = \frac{D}{T} = \frac{3136}{8008} = 0.3916

39.16% probability of selecting three Democrats and three Republicans
