According to a poll, 30% of voters support a ballot initiative. hans randomly surveys 5 voters. what is the probability that exactly 2 voters will be in favor of the ballot initiative? round the answer to the nearest thousandth.

Answer with explanation:

Number of voters who support ballot initiative = 30 %=0.30

Number of voters who does not support this initiative

                                                                     =0.70

Number of voters selected for Surveying =5

Probability that exactly 2 voters will be in favor of the ballot initiative is given by ,if P denotes Success and Q denotes failure

If we round up to nearest thousandth, Required Probability = 0.309

you never say the total so we cant find the percentage used for petrol

step-by-step explanation:

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
