3) 113.1 = Area
4) You would need to adjust how many number places of pi you use for how huge the number you need to calculate for.
5) To write an exact number for an irrational expression you need to calculate then round to the nearest hundredths after you get the number for either radius, diameter, or area. To find the approximate value you only use the minimum numbers such as 3.14 instead of 3.14159...
6) How this helped me better estimate the value of an irrational expression is by using more numbers for every extra number place the circle has in the diameter.

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
Answers
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]

Part B
What is the total length of 13 rods?
Answers
Answer
65 feet long
Step-by-step explanation:
15x5 is 65
Answer:
Step-by-step explanation:
5 feet ÷ 8 = 5/8 of a foot for each rod.
(In inches that would be 5/8 × 12 inches = (5 × 12)/8 inches = 60/8 inches = 15/2 inches = 7 1/2 inches.)
13 rods would be 13 × 5/8 feet = (13 × 5)/8 feet = 65/8 feet = 8 1/8 feet

Answers
Answer:
sinQ=cosR
Step-by-step explanation:
First we need to find out the measure of ∠R.
The sum of all the angles in a triangle add up to 180. Therefore:
∠Q+∠R+∠S=180
66+∠R+90=180
∠R=180-156
∠R=24°
Since ∠Q≠∠R, sinQ≠sinR. So the first option is incorrect - let's try the second one.
sinQ=cosR
sin66=cos24
0.9135454576=0.9135454576
So the second equation is the correct relation.

Answers
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
