First subtract the 20 from both sides so it is 3x=2x+4 thens ubtract the 2 so x equals 4
Answer:
0.35 is the mean of the sampling distribution of the proportion.
Step-by-step explanation:
We are given the following in the question:
Percentage of voters who voted for recall = 35%

Sample size, n = 3150
We have to find the mean of the sampling distribution.
Formula for mean of sampling distribution:

Putting values, we get,

Thus, 0.35 is the mean of the sampling distribution of people sampled in an exit poll who voted for the recall.

Step-by-step explanation:
Sqrt (53) = 10 * sqrt (0.53)
0.53 = 64/121
sqrt (0.53) = sqrt (64)/ sqrt (121) = 8/11 = 0.7273
Therefore sqrt (53) = 10 * 0.7273 = 7.27
sqrt (108) = 10 * sqrt (1.08)
sqrt (1.08) = sqrt (676/625) = 26/25 = 1.04
Therefore sqrt (108) = 10 * 1.04 = 10.4
sqrt (128) = 10 * sqrt (1.28)
sqrt (1.28) = sqrt (289/225) = 17/15 = 1.133
Therefore sqrt (108) = 10 * 1.133 = 11.33
