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

Answer:
Age Group Number of People 18–24 80 25–31 120 32–38 40 39–45 20
The data in each bar is how many people in that group.
So 18-24 has 80 people
25-31 has 120 people
32 -38 has 40 people
39-45 has 20 people
Step-by-step explanation:
Answer:
28/289
Step-by-step explanation:
7 red, 4 blue, and 6 white = 17 marbles
P ( red ) = number of red / total
= 7/17
Replace the marble
7 red, 4 blue, and 6 white = 17 marbles
P ( blue ) = number of blue / total
= 4/17
P (red, replace, blue) = 7/17* 4/17
=28/289
w-4=-12-3w
Add 12 to each side:
w + 8 = -3w
Subtract 1w from each side:
8 = -4w
Divide both sides by -4:
w = 8 / -4
w = -2
