Point A = 0.62Point B = 7/9Point C = 10/9===================================================
Explanation:
Using a calculator, we get the following decimal approximations
1/3 = 0.3332/3 = 0.6677/9 = 0.77810/9 = 1.111Based on that, we see that 0.620 is between 0.333 and 0.667
We can say 0.333 < 0.620 < 0.667
which is the same as 1/3 < 0.62 < 2/3
So, 0.62 is between 1/3 and 2/3
0.62 will be placed at point A.
--------------
Since 7/9 = 0.778 is between 2/3 = 0.667 and 1, this means,
7/9 will go to point B.
--------------
Since 1.111 > 1, this means 10/9 > 1
Therefore 10/9 will go to point C

27.5% of US adults are college graduates.
A) Use StatKey or other technology to generate a sampling distribution for the sample proportion of college graduates using a sample size of n = 5. Generate at least 1000 sample proportions. Give the center of the sampling distribution and give the standard error.
B) Repeat part (a) using a sample size of n = 500.
C) If we took many samples of size 50 from the population of all inductees and recorded the proportion who were performers for each sample, what shape do we expect the distribution of sample proportions to have where do we expect it to be centered?
Answers
Complete Question
The complete question is shown on the first uploaded image
Answer:
a
center is 0.275
[tex]SE = 0.063[/tex]
b
center is 0.275
[tex]SE = 0.020[/tex]
Step-by-step explanation:
considering question a
From the question we are told that
The sample size is n = 50
The proportion of US adults are college graduates is p = 0.275
Generally the center is equivalent to the proportion so the center is 0.275
Generally the standard error is
[tex]SE = \sqrt{\frac{p * (1- p)}{ n} }[/tex]
=> [tex]SE = \sqrt{\frac{0.275 * (1- 0.275)}{ 50} }[/tex]
=> [tex]SE = 0.063[/tex]
considering question b
The sample size is n = 500
The proportion of US adults are college graduates is p = 0.275
Generally the center is equivalent to the proportion so the center is 0.275
Generally the standard error is
[tex]SE = \sqrt{\frac{p * (1- p)}{ n} }[/tex]
=> [tex]SE = \sqrt{\frac{0.275 * (1- 0.275)}{ 500} }[/tex]
=> [tex]SE = 0.020[/tex]
In the sampling distribution, the center of the sampling distribution is 0.275 and the standard error is 0.063.
What is sampling distribution?A sampling distribution simply means the probability distribution that is gotten from a larger number of samples that are drawn from a population.
In this case, the center of the sampling distribution is 0.275 and the standard error is 0.063. The standard error will be:
= [p × (1 - p)]/n
= [0.275 × (1 - 0.275)]/50
= 0.0039875
= ✓0.0039875
= 0.063
Also, when the sample is 500, the center of the sampling distribution is 0.275 and the standard error is 0.020.

In a certain chemical, the ratio of zinc to copper is 3 to 17. A jar of the chemical contains 799 grams of copper. How many grams of zinc does it contain?
Answers
Answer:
let's see what to do buddy...
Step-by-step explanation:
[tex] \frac{zinc}{copper} = \frac{3}{17} \\ \\ \frac{zinc}{799} = \frac{3}{17} [/tex]
Multiply the sides of the equation by 799
[tex]zinc = \frac{3}{17} \times 799 \\ \\ zinc = \frac{3}{17} \times 17 \times 47 \\ \\ zinc = 3 \times 47 = 141 [/tex]
So A jar of the chemical contains 141 grams of zinc.
And we're done.

Albuterol is used to calm bronchospasm. It has a biological half-life of 7 hours and is normally inhaled as a 1.25 mg dose. (Note: Use the concepts of half-life or doubling time. The biological half-life of a substance is the amount of time it takes for the physiologic or radiologic activity of that substance to reduce by half.)
Required:
a. Find a model for the amount of albuterol left in the body t hours after an initial dose of 1.25 mg.
b. How much albuterol is left in the body after 24 hours?
Answers
Answer:
a. N(t) = 1.25 (1/2)^t/7
b. 0.1160933038mg.
Step-by-step explanation:
The formula for half life =
N(t) = No(1/2)^t/t½
Where N(t) = Amount of Substance left
No = Initial amount not Substance
t = time after t years
t½ = Half life of the substance
From the question:
No = 1.25mg
t½ = 7 years
a. Find a model for the amount of albuterol left in the body t hours after an initial dose of 1.25 mg.
N(t) = No(1/2)^t/t½
No = 1.25mg
t½ = 7 years
N(t) = 1.25 (1/2)^t/7
b. How much albuterol is left in the body after 24 hours?
Using the model in the above question
N(t) = 1.25 (1/2)^t/7
N(t) = 1.25(1/2)^24/7
N(t) = 1.25(0.5)^3.4285714286
N(t) = 0.1160933038mg
Therefore, the quantity of albuterol left in the body after 24 hours is 0.1160933038mg.

Answer:
(A)
N(T(t)) = 416t² - 242.4 - 135.16
(B)
Time = 27.30 hours
Step-by-step explanation:
Given
N(T) = 26T² - 123T + 25
T(t) = 4t + 1.2
Solving for the composite function.
Substitute T for 4t + 1.2 in N(T)
N(T(t)) = 26(4t + 1.2)² - 123(4t + 1.2) + 25
N(T(t)) = 26(4t+1.2)(4t + 1.2) - 123(4t + 1.2) + 25
N(T(t)) = 26(16t² + 9.6t + 1.44) - 492t - 147.6 + 25
N(T(t)) = 416t² + 249.6t + 37.44 - 492t - 172.6
N(T(t)) = 416t² + 249.6t - 492t + 37.44 - 172.6
N(T(t)) = 416t² - 242.4 - 135.16
Solving for time.
We have that
N(T) = 16044
N(T) = 26T² - 123T + 25
This gives
16044 = 26T² - 123T + 25
26T² - 123T + 25 - 16044 = 0
26T² - 123T - 16019 = 0
Solve by quadratic, we have.
T = 27.299506396472
Or
T = -22.568737165703
Since time can't be negative
T = 27.299506396472
T = 27.30 (approximately)

What is the equation of a line passing through two points?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
Let the equation of the line pass through (x₁, y₁) and (x₂, y₂). Then the equation of the line is given as,
[tex]\rm (y - y_2) = \left (\dfrac{y_2 - y_1}{x_2 - x_1} \right ) (x - x_2)[/tex]
Taking only two points from the table will be (4, 6) and (12, 8). Then the equation of the line is given as,
(y - 6) = [(8 - 6) / (12 - 4)](x - 4)
y - 6 = 1/4(x - 4)
y - 6 = (1/4) x - 1
y = (1/4)x + 5
The y-intercept and slope of the line described by these points will be y = (1/4)x + 5.
