From the records of a health-insurance companies in Pennsylvania, it is known that 58% of the accounts include dental coverage. A researcher would like to take a random sample of 500 accounts to review. Find the standard deviation of the sample proportion in this situation. Give your answer to 4 decimal places. For help on how to input a numeric answer, please see "Instructions for inputting a numeric response."
Answers
Answer: 0.0221
Step-by-step explanation:
We know that the formula to find the standard deviation of the sample proportion is :
, where p = proportion of success.
n= sample size.
As per given , we have
p=0.58
n= 500
Then, the standard deviation of the sample proportion in this situation would be :
Hence, the standard deviation of the sample proportion in this situation is 0.0221 .

Consider an optimization model with a number of resource constraints. Each indicates that the amount of the resource used cannot exceed the amount available. Why is the shadow price of such a resource constraint always zero when the amount used in the optimal solution is less than the amount available?

Answer:
"all real numbers"
Step-by-step explanation:
The domain is the set of x-values for which the function is defined.
Domain is also the input of the function (graph).
The graph shown has arrows in both directions. It means that the graph goes on in both directions. If we were to think correctly, we would say the graph would go on-and-on in both +ve x and -ve x directions. So there would be values of x for all real numbers (going to infinity and negative infinity)
Hence, the domain is all real number, the last answer choice is right.

Answer:
360 feet
Step-by-step explanation:
Area = 2XY = 2 · 2,700 = 5,400
Perimeter = (2 · 2X) + 3Y = 4X + 3Y
Y = 5,400 / 2X = 2,700 / X
Perimeter = 4X + 8,100/X
P'(x) = 4 - 8,100/X² = 0
4 = 8,100/X²
X² = 8,100 / 4 = 2,025
X = √2,025 = 45
Y = 2,700 / 45 = 60
Perimeter = (4 · 45) + (3 · 60) = 180 + 180 = 360 feet

Graph f(x) = 3x + 4 and h(x) = f(x) +1
Answers
The coordinatepoints to plot on the graph are (0, 5) and (1, 8). The graph for the given functions are plotted below.
The given functions are f(x) = 3x + 4 and h(x) = f(x) +1.
What is the function?
Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Here, h(x)=3x+5
The graph of f(x) = 3x + 4 is as follows:
Graph the line using the slope and y-intercept, or two points.
Slope: 3
y-intercept: (0, 4)
The coordinatepoints to plot on the graph are (0, 4) and (1, 7)

Answer:
t = 40
Step-by-step explanation:
Given the logarithmic expression:
Use the Logarithmic Property (Quotient Rule):
Next, using the Logarithmic Property:
We must determine the possible value oft that can be divided by 5 to produce a quotient of 8 that will make the logarithmic property, , true. In that case, t = 40 divided by 5 results in a quotient of 8.
Therefore, the value oft = 40.
