Answer:
The value is 
Step-by-step explanation:
From the question we are told that
The sample size is n = 500
The population proportion is p = 0.47
Generally given that the sample size is sufficiently large , the mean of this sampling distribution is mathematically represented as

Generally the standard deviation of the sampling distribution is mathematically represented as

=>
=>
Gnerally the probability that the proportion of voters in the sample of Region A who support the ballot measure is greater than 0.50 is mathematically represented as


=> 
From the z table the area under the normal curve to the left corresponding to 1.3453 is

So

3/8 = 0,375
0,375 * 100% = 37,5 %
Answer:11.9090909
Step-by-step explanation:
20% x 50 =(20 / 100) x 50 = (20 x 50) / 100 = 1000 / 100 = 10
answer is 10
Ok so the answer is 160/32
