<span>5b–2=18, This is correct because you have to take 5 times Ben's number of goals, subtract 2 and that equals Rea's goals, 18. </span>

2. In a given country, records show that of the registered voters, 45% are Democrats, 35% are Republicans, and 20% are independe

Answer:

P(R) = 0.14

P(I) = 0.16

P(D) = 0.315

Step-by-step explanation:

Let Democrat = D

Republican = R

Independent = I

If 45% are Democrats, 35% are Republicans, and 20% are independents, then

Total registered voters = 100

In an election, 70% of the Democrats, 40% of the Republicans, and 80% of the independents voted in favor of a parks and recreation bond proposal. That is,

D = 0.7 × 45 = 31.5

R = 0.4 × 35 = 14

I = 0.8 × 20 = 16

If a registered voter chosen at random is found to have voted in favor of the bond, what is the probability that the voter is

a Republican:

P(R) = 14 /100 = 0.14

an Independent

P(I) = 16/100 = 0.16

a Democrat

P(D) = 31.5/100 = 0.315

A circle has a radius of 5 centimeters. What is the area?

schepotkina [342]

Answer:

$25\pi$

Step-by-step explanation:

The formula for the area of a circle is $A=\pi r^{2}$ , r is your radius, A is your area, and π is pi (3.1415...). You plug in your radius, or 5 into r, square it, 25, and multiply it by pi. You may be asked to use a certain number of digits of pi, and in that case you multiply for example 3.14 by 25, however $25\pi$ is the exact answer.
