How many of the 3271 subjects used at least one prescription medication? Round to the nearest integer asneeded.)
Answer:
2902
Step-by-step explanation:
Let the total number of adults within the mentioned age bracket be n=3271
The proportion of adults who used at least one prescription medication be p=88.7%=0.887
The point estimate of population is given by
where x is number of individuals in the sample with the specified characteristics and n is the sample size.
Let x be the adults who used at least one prescription medication
Do you need to solve for a certain variable?
Answer:
karen walked a total of 12 and 1/30 miles.
Step-by-step explanation:
The original are would be 48.
Since we know that the length and width are two consecutive even integers, we can model them as follows:
Width = x
Length = x + 2
This works because no matter what even number is put in for x, the length will also be even.
Now we know if we subtract 3 from the width, we have a new rectangle that gives us an area of 24 inches. Therefore, our new triangle has the following:
Width: x - 3
Length: x + 2
Area: 24
And we can plug this into the equation.
Length* Width = Area
(x + 2)(x - 3) = 24
x^2 - x - 6 = 24
x^2 - x - 30 = 0
This is not a quadratic that we can factor to show the following:
(x - 6)(x + 5) = 0
This gives us the answers of x = 6 and x = -5. Since a side can't be negative, we throw out the x = -5 and the answer is x = 6.
So if we go back to the original rectangle, we know:
Width = x = 6
Length = x + 2 = 8
Area = 6*8 = 48
Answer:
C
Step-by-step explanation:
As you can see, the dot on the line is the starting point and it is open.
An open dot means less than or more than. An closed dot means less than or equal to / more than or equal to.
The line is going right starting from -5, so it is more than 5.
