During the 2004 senatorial campaign in a large southwestern state, illegal immigration was a major issue. One of the candidates

argued that illegal immigrants made use of educational and social services without having to pay property taxes. The other candidate pointed out that the cost of new homes in their state was 20–30% less than the national average due to the low wages received by the large number of illegal immigrants working on new home construction. A random sample of 5,500 registered voters was asked the question, "Are illegal immigrants generally a benefit or a liability to the state’s economy?" The results were as follows: 3,500 people responded "liability," 1,500 people responded "benefit," and 500 people responded "uncertain."
a. What is the population of interest?
b. What is the population from which the sample was selected?
c. Does the sample adequately represent the population?
d. If a second random sample of 5,000 registered voters was selected, would the results be nearly the same as the results obtained from the initial sample of 5,000 voters? Explain your answer.

Answer:

a

   The population of interest is the registered voters , this is because  it is the population from which the sample size is selected from.

b

The  population is the registered voters of the  large southwestern state

c

Well this does not adequately represent the population because this sample where selected from only the registered voters of the  large southwestern state  and not the whole country

d

   Yes the result will be nearly the same because

  1.    Both samples are selected from the same population
  2.    The size of the  sample selected is sufficiently large to approximate      the population

Step-by-step explanation:

From the question we are told that

   The sample size is  n =  5,500

Considering question a

 What is the population of interest

   The population of interest is the registered voters , this is because  it is the population from which the sample size is selected from.

Considering question b

What is the population from which the sample was selected    

  The  population is the registered voters of the  large southwestern state  

Considering question c

    Does the sample adequately represent the population

Well this does not adequately represent the population because this sample where selected from only the registered voters of the  large southwestern state  and not the whole country

Considering question d

   Yes the result will be nearly the same because

  1.    Both samples are selected from the same population
  2.    The size of the  sample selected is sufficiently large to approximate      the population

If x=9 and y=−3, evaluate the following expression:7(2x−3y)​
LuckyWell [14K]

Answer:

189

Step-by-step explanation:

You can replace the values of x with 9 and the values of y with (-3).

7(2x-3y) = 7(2 × 9 - 3 × -3)

             = 7(18 - -9)

             = 7(18+9)

             = 7 × 27

             = 189

Three times as many children as adults attended a concert on Saturday. An adult ticket cost $7 and a child’s ticket cost $3. The
Ierofanga [76]

For this case we propose a system of equations:

x: Let the variable representing the number of children in the concert

y: Let the variable representing the number of adults at the concert

According to the assistance we have:

x = 3y

According to the cost we have:

3x + 7y = 6000

Substituting the first in the second equation we have:

3 (3y) + 7y = 6000\\9y + 7y = 6000\\16y = 6000\\y = \frac {6000} {16}\\y = 375

Thus, the concert was 375 adults.

On the other hand we have:

x = 3 (375) = 1125

Thus, the concert was 1125 children.

In total they were:

375 + 1125 = 1500 people

ANswer:

The concert was 1500 people
