Answer:

<em>X </em>is equal to 2

Step-by-step explanation:

90 = 13x + 34 + 10x + 10

Combine Like Terms:

90 = 23x + 44

Subtraction Property of Equality:

90 - 44 = 23x + 44 - 44 ---> 46 = 23x

Division Property of Equality:

46 ÷ 23 = 23x ÷ 23 ---> 2 = x

<h3>Check Your Work:</h3>

90 = 13x + 34 + 10x + 10

Fill In Variables:

90 = 13(2) + 34 + 10(2) + 10

90= 26 + 34 + 20 + 10

90 = 60 + 30

90 = 90

Answer:

x = 2

Step-by-step explanation:

Set the two equations 13x+34 and 10x+10 together to add up to 90 on the right which should look like this 13x + 34 + 10x + 10 = 90.  Combine the two x-values to get 23x and the two other numbers to get 44.  Your equation should now be 23x + 44 = 90.  Subtract 44 on both sides to get this equation 23x = 46.  Divide 23 on both sides to get your x value which is 2.

a pollster wishes to estimate the proportion of united states voters who favor capital punishment. how large a sample is needed
olasank [31]

The sample size must be 543 so the sample proportion is will not differ by 5%

We are given the following in the question:

Margin of error = 5%

Confidence interval:

p ±z√(p'(1 - p')/n)

Margin of error =

p = ±z√(p'(1 - p')/n)

Since no particular proportion is given, we take

p' = 0.5

Z critical at α 0.02 is ± 2.33

Putting values, we get,

p = ±z√(p'(1 - p')/n)

2.33 x √(0.5(1 - 0.5)/n)

√n = 2.33x 0.5/0.05

n = 542.89 = 543

Thus, the sample size must be 543 so the sample proportion is will not differ by 5%
