In 2009 a survey of Internet usage found that 79 percent of adults age 18 years and older in the United States use the Internet. A broadband company believes that the percent is greater now than it was in 2009 and will conduct a survey. The company plans to construct a 98 percent confidence interval to estimate the current percent and wants the margin of error to be no more than 2.5 percentage points. Assuming that at least 79 percent of adults use the Internet, which of the following should be used to find the sample size (n) needed?
a. 1.96 â0.5/n = 0.025
b. 1.96 â0.5(0.5)/n = 0.25
c. 2.33 â0.5(0.5)/n =0.05
d. 2.33 â0.79(0.21)/n= 0.025
Answer:
[tex]0.025 = 2.33\sqrt{\frac{0.79*0.21}{n}}[/tex]
Option d.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error is:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
79 percent of adults age 18 years and older in the United States use the Internet.
This means that [tex]\pi = 0.79[/tex]
98% confidence level
So [tex]\alpha = 0.02[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.02}{2} = 0.99[/tex], so [tex]Z = 2.33[/tex].
Which of the following should be used to find the sample size (n) needed?
We have to find n for which [tex]M = 0.025[/tex]
So the equation is:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.025 = 2.33\sqrt{\frac{0.79*0.21}{n}}[/tex]
Option d.

(-3,-8)
(-3,8)
(3,-8)
Answer:
(3,8)
Step-by-step explanation:
THIS IS AN EXAMPLE FOR ANY PROBLEM!!
Get the equation in the form y = ax2 + bx + c.
Calculate -b / 2a. This is the x-coordinate of the vertex.
To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y. This is the y-coordinate of the vertex.

Option76 4
Answer:
78
Step-by-step explanation:
The range is the difference between the highest and lowest number:

You are making sandwiches for a large party. Each sandwich has two slices of bread, one slice of turkey, two slices of cheese, three slices of tomato and 5 slices of cucumber. How many sandwiches will you get from ... 10 slices of bread and 20 slices of cucumber
Question:
You are making sandwiches for a large party. Each sandwich has two slices of bread, one slice of turkey, two slices of cheese, three slices of tomato and 5 slices of cucumber. How many sandwiches will you get from 10 slices of bread and 20 slices of cucumber? assuming you have plenty of everything
Answer:
4 sandwiches
Step-by-step explanation:
Given
1 Sandwich contains:
[tex]Bread = 2\ slices[/tex]
[tex]Turkey = 1\ slice[/tex]
[tex]Cheese = 2\ slices[/tex]
[tex]Tomato = 3\ slices[/tex]
[tex]Cucumber = 5\ slices[/tex]
Required
Number of sandwiches from 10 slices of bread and 20 slices of cucumber?
Since we are to assume that every other thing is in abundance, we will only consider the unit amount of bread and cucumber
[tex]Bread = 2\ slices[/tex]
[tex]Cucumber = 5\ slices[/tex]
Express as ratio
[tex]Bread : Cucumber = 2 : 5[/tex]
When the ratio is multiplied by 5, the slice of cucumber (25) will exceed the available slices (20).
So, we multiply by 4
[tex]Bread : Cucumber = 2*4 : 5*4[/tex]
[tex]Bread : Cucumber = 8 : 20[/tex]
This implies that:
8 slices of bread and 20 slices of cucumber are used
Hence:
4 sandwiches can be made

4
hours on Wednesday. Next week Andres will practice with his band for the same number of hours
on Monday, Tuesday, and Wednesday.
What is the total number of hours Andres will practice with his band over these 6 days?
Answer:
[tex]Total = 104\ hrs[/tex]
Step-by-step explanation:
Given
[tex]Monday = 15\ hrs[/tex]
[tex]Tuesday = 13\ hrs[/tex]
[tex]Wednesday = 24\ hrs[/tex]
Required
Determine the hours of practice over 6 days
First, we calculate the hours for the given 3 days.
[tex]Hours = Monday + Tuesday + Wednesday[/tex]
[tex]Hours = 15\ hrs + 13\ hrs + 24\ hrs[/tex]
[tex]Hours = 52\ hrs[/tex]
The hours of practice for the other three days is also 52 hours.
So, the total is:
[tex]Total = 52\ hrs + 52\ hrs[/tex]
[tex]Total = 104\ hrs[/tex]

(4,18); (6,22); (8,26)
Step-by-step explanation:
Plug in the numbers 4, 6, and 8, in for d using the equation.
c=2d+10
c=2(4)+10
c=8+10
c=18
(4,18)
c=2d+10
c=2(6)+10
c=12+10
c=22
(6,22)
c=2d+10
c=2(8)+10
c=16+10
c=26
(8,26)
Answer:
14
18
22
26
Step-by-step explanation:
c = 2d + 10
1st one: substitute 2 for d
c = 2 x 2 + 10
c = 14
2nd one: substitute 4 for d
c = 2 x 4 + 10
c = 18
3rd one: substitute 6 for d
c = 2 x 6 + 10
c = 22
4th one: substitute 8 for d
c = 2 x 8 + 10
c = 26
