Determine if each statement about the relation {(3,7),(5,1),(6,4),(2,5)} is true or false.
a. The domain of the relationship is {2,3,5,6}.
b. The range of the relation is {1,4,5,7}.
c. The value 5 is a member of both the domain and range.
Answers
Answer:
a. true
b. true
c. True
Step-by-step explanation:
a. The domain of a relation includes all possible set of data that are the x-values. Therefore, the domain of the relationship given would be: {2, 3, 5, 6}.
a is True.
b. The range includes all corresponding y-values. Therefore,
Range would be {1 4, 5, 7}
b is Tire.

The sample of any set would be smaller version of a larger group. It is often a subset that contains some or all the characteristics of the main set, or the larger general population. The usage of samples comes into play in statistics when the population sizes of interest are too large for the test to contain all the needed members for it to take place. So, from this question, the sample size is the 325 questionnaires that were returned in the first place.
2. C
I thin the answer is survey with little bias since the voters know what they want. This is because while answering the survey, the voters know who they want to vote for upfront, and didn't need to gave their mind change by anyone on the survey.

Over the next 17 months you have to read at least 68 books. You have to read x books per month.
The inequality 17x2 68 represents this situation. Solve the inequality to find the number of books
you have to read per month.
Answers
Answer:
You have to read 4 or more books per month.
Step-by-step explanation:
Given that:
Number of months to read the books = 17 months
Number of books to read = 68 at least
Number of books per month = x
The inequality for the situation is;
[tex]17x\geq 68[/tex]
Dividing both sides by 17
[tex]\frac{17x}{17}\geq \frac{68}{17}[/tex]
x ≥ 4
Hence,
You have to read 4 or more books per month.

If a circle has a diameter of 24 inches, which expression gives its area in
square inches?
O A. 12.
O B. 242.17
O C. 24. 1
O D. 122.77
Answers
Answer:
D. 12²•π
Step-by-step explanation:
Area of a circle = πr²
Radius (r) = ½ of diameter = ½*24 = 12 inches
Plug in the value into the area
Area = π * (12)²
Area = π * 12²
Area = 12²•π

A ball is thrown with an initial speed of 17 mph in a direction that makes an angle of 22 degrees with the positive x-axis. Express the velocity vector v in terms of i and j.
Answers
Answer:
The speed of the ball in terms of i and j is (15.76 i, 6.37 j)
Step-by-step explanation:
Given;
velocity of the ball, v = 17 mph
angle of inclination, θ = 22⁰
The horizontal component of the velocity is calculated as;
[tex]V_x = Vcos\theta\\\\V_x = 17cos(22)\\\\V_x = 15.76 \ i[/tex]
The vertical component of the velocity is calculated as;
[tex]V_y = Vsin\theta\\\\V_y = 17sin(22)\\\\V_y = 6.37 \ j[/tex]
Therefore, the speed of the ball in terms of i and j is (15.76 i, 6.37 j)

5/6 = 10/ W+3 solve for W
Answers
Answer:
[tex]\huge\boxed{w=9}[/tex]
Step-by-step explanation:
In order to solve for w here, let's write the proportion.
[tex]\frac{5}{6} = \frac{10}{w+3}[/tex]
To solve for w, we need to get it isolated on one side of the equation. To do this, we can first multiply both sides by 6 and w+3 in order to get rid of the denominators.
[tex]\frac{5}{6} \cdot 6 \cdot w+3 = \frac{10}{w+3} \cdot (w+3) \cdot6[/tex] [tex]5(w+3) = 60[/tex] [tex]5w+15 = 60[/tex] [tex]5w = 45[/tex] [tex]w = 9[/tex]Therefore, w=9.
