Answer:
8, 7.92, 2.81
Step-by-step explanation:
For each Social Security recipient, there are only two possible outcomes. Either they are too young to vote, or they are not. The probability of a Social Security recipient is independent of any other Social Security recipient. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:
The variance of the binomial distribution is:
The standard deviation of the binomial distribution is:
In this problem, we have that:
So
Mean:
The variance of the binomial distribution is:
The standard deviation of the binomial distribution is:

Answer: The solution of the system of equations is (1,7).</h3>
Step-by-step explanation: Given system of equations
y = 5x + 2 and
3x = –y + 10.
Substituting y= 5x+2 in second equation, we get
3x = -(5x+2) +10.
Distributing minus sign in (5x+2), we get
3x= -5x-2+10.
3x = -5x + 8.
Adding 5x on both sides, we get
3x+5x = -5x+5x +8
8x = 8.
Dividing both sides by 8, we get
8x/8 = 8/8
x = 1.
Plugging x=1 in first equation, we get
y = 5(1) +2
y = 5+2=7.
<h3>Therefore, the solution of the system of equations is (1,7).</h3>
