Answer:

I believe it is: 6n+8+7y+4m

Step-by-step explanation:

You can't do anything about the numbers with variables afterwards, so you just list those and you just add and subtract the numbers without variables.  Since the top and bottom are the same, you just list it once.  Sorry, not the best explanation.  Please let me know if I am wrong.  It's been a while since I had to any type of algebra.

-11w + 7 + 10w = 19 + 2W<br> What does the variable W equal?
Goryan [66]

Answer:

w = -4

Step-by-step explanation:

-11w + 7 + 10w = 19 + 2w

-1w + 7 = 19 + 2w

-1w + 1w + 7 = 19 + 2w + 1w

7 = 19 + 3w

7 - 19 = 19 - 19 + 3w

-12 = 3w

\frac{-12}{3} = \frac{3w}{3}

-4 = w

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 %
