Simple Random Sample of Size 25:
Chances are, since you are studying AP Statistics, you plan to earn at least a bachelor's degree from college. According to the U.S. Census Bureau, 29% of Americans age 25 years or older have already earned a bachelor's or more advanced degree. You decide to randomly select 58 adults over the age of 25 to ask if they have earned at least a bachelor's degree. Describe the sampling distribution of the proportion of respondents who have earned at least a bachelor's degree.
Answer:
By the Central Limit Theorem, it is approximately normal with mean 0.29 and standard deviation 0.0596
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]
According to the U.S. Census Bureau, 29% of Americans age 25 years or older have already earned a bachelor's or more advanced degree.
This means that [tex]p = 0.29[/tex]
You decide to randomly select 58 adults over the age of 25 to ask if they have earned at least a bachelor's degree.
This means that [tex]n = 58[/tex]
Describe the sampling distribution of the proportion of respondents who have earned at least a bachelor's degree.
By the Central Limit Theorem, it is approximately normal with mean [tex]\mu = p = 0.29[/tex] and the standard deviation is [tex]s = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.29*0.71}{58}} = 0.0596[/tex]

help :( math for 8th
Answer:
She should add 10x to both sides
Step-by-step explanation:
Answer:
Step-by-step explanation:
x² - 10x - 2 = 0 {Add 2 to both sides}
+2 = +2
x² - 10x = 2
Now to find what to add both sides, divide the co-efficient of x by 2
10/2 = 5
Add 5² to both sides
x² - 10x + 25 = 5²
(x - 5)² = 5²
Take square root both sides,
x - 5 = ± 5
x- 5 = 5 ; x - 5 = -5
x = 5+5 ; x = -5 + 5
x = 10 ; x = 0

special right triangle desmo
9514 1404 393
Answer:
x = 15√3
y = 30
Step-by-step explanation:
In a 30°-60°-90° "special" triangle, the ratios of side lengths are ...
1 : √3 : 2
Your diagram shows the short side is 15, so the other sides can be found by multiplying the above ratio numbers by 15.
1 : √3 : 2 = 15 : x : y = 15 : 15√3 : 30
x = 15√3
y = 30
Identify the lateral area and surface area of a right cone with radius 7 cm and slant height 15 cm.
Answer:
lateral area is 329.7 and the surface area is 483.56
Step-by-step explanation:
Lateral area = [tex]\pi (7)(15) = 105\pi = 329.7\\[/tex]
Surface area = lateral area + base area
Base area= [tex]\pi r^{2}[/tex] = [tex]\pi (7)^{2}[/tex] = [tex]49\pi[/tex]
Surface area = 105[tex]\pi + 49\pi = 154\pi = 483.56[/tex]

Chile anyways so the equation to the problem is 3(x+5) =20. And all you have to do is split the (x+5) into three parts on the tape diagram and it would all equal 20.
What is the solution to the following equation?
5(2x –6) + 20 = 10
Answer:
Step-by-step explanation:
Simplifying
5(2x + -6) + 20 = 10
Reorder the terms:
5(-6 + 2x) + 20 = 10
(-6 * 5 + 2x * 5) + 20 = 10
(-30 + 10x) + 20 = 10
Reorder the terms:
-30 + 20 + 10x = 10
Combine like terms: -30 + 20 = -10
-10 + 10x = 10
Solving
-10 + 10x = 10
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '10' to each side of the equation.
-10 + 10 + 10x = 10 + 10
Combine like terms: -10 + 10 = 0
0 + 10x = 10 + 10
10x = 10 + 10
Combine like terms: 10 + 10 = 20
10x = 20
Divide each side by '10'.
x = 2
Simplifying
x = 2
Answer:
x=2
Step-by-step explanation:
Let's solve your equation step-by-step.
5(2x−6)+20=10
Step 1: Simplify both sides of the equation.
5(2x−6)+20=10
(5)(2x)+(5)(−6)+20=10(Distribute)
10x+−30+20=10
(10x)+(−30+20)=10(Combine Like Terms)
10x+−10=10
10x−10=10
Step 2: Add 10 to both sides.
10x−10+10=10+10
10x=20
Step 3: Divide both sides by 10.
10x
10
