PLEASE ANSWER REALLY DESPERATE FOR A ANSWER

Answer:

x = 3

x = 0

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation:

2x^2 - 6x = 0

Pull out like factors

2x * (x - 3) = 0

Solve: 2x = 0

Divide both sides of the equation by 2:

x = 0

Solve: x-3 = 0

Add 3 to both sides of the equation:

x = 3

A polling organization announces that the proportion of American voters who favor congressional term limits is 64%, with a 95% c
EastWind [94]

Answer:

Hence when C.I. is 80% then Margin of error will be 1.9591%

Step-by-step explanation:

Given:

1st Margin of error(MOE)=3%

1st C.I.=95%

2nd C.I.=80%

To Find:

MOE at 80%

Solution:

The proportion is 64 % i.e. is constant for both MOE

Proportion is given by (P),

P=x/n

Where x= favors congressional terms

n= total voters or sampled voters.

There values are same or constant.

i.e standard deviation is also constant

Now Formula for MOE is given by

MOE=Z*[Standard devation/Sqrt(n)]

here Z is value for confidence interval

MOE is directly proportional to the Z-value

So

MOE=K*Z-value         ... where k is proportionality constant.

MOE/Z-value              ....ratio is constant

So , for 95 % Z=1.96 and for 80% Z=1.28

MOE(1st)/(Z-value 1st)=MOE(2nd)/(Z-value 2nd)

3/1.96=MOE(2nd)/1.28

MOE(2nd)=(3/1.96)*1.28

MOE(2nd)=1.5306*1.28

=1.9591 %
