Answer:

2(4 + 2z) = 8 + 4z

or

2(4 + 2z) = 0

z = -2

Step-by-step explanation:

How to solve:

2(4 + 2z)

Distribute:

2(4 + 2z)

2(4) + 2(2z)

Multiply:

2(4) + 2(2z)

8 + 4z

8 + 4z is the simplified expression.

How to solve:

2(4 + 2z) = 0

Distribute:

2(4 + 2z) = 0

2(4) + 2(2z) = 0

Multiply:

2(4) + 2(2z) = 0

8 + 4z = 0

Subtract 8 on both sides:

8 + 4z = 0

-8          -8

4z = -8

Divide by 4 on both sides:

4z = -8

/4      /4

z = -2

z = -2 is the answer if 0 is on the other side of the equal sign

consider a population of voters. suppose that that there are n=1000 voters in the population, 30% of whom favor jones. identify
Drupady [299]

Answer:

P(B)=0.30

Step-by-step explanation:

Out of 1000 Voters, 30% favor Jones.

Event S=Favors Jones on First Trial

Event B=S occurs on Second Trial

P(S)=0.30

P(S')=1-0.30=0.70

Event B could occur in two ways

  1. The first two trials are a success
  2. The first trial is a failure and the second trial is a success.

Therefore,

P(B)=P(SS)+P(S'S)

=(0.3X0.3)+(0.7X0.3)

=0.09+0.21

=0.3

Therefore, the probability of event B(that event S occurs on the second trial), P(B)=0.30.

5. Solve the equation. 8/x+3 = 1/x+1
Helga [31]

Answer:

x = -5/7

Step-by-step explanation:

8               1

---------- = ----------

x+3           x+1

Using cross products

8 (x+1) = 1 (x+3)

Distribute

8x+8 = x+3

Subtract x from each side

8x-x +8 = x-x+3

7x+8 =3

Subtract 8 from each side

7x +8-8 =3-8

7x = -5

Divide each side by 7

7x/7 = -5/7

x = -5/7
