Answer:
i think the answer is B because 3/4 is more than 2/3
Answer: D. Ordinal
Step-by-step explanation:
There are four levels of measurements scales of a variable :-
- Nominal scale : Used for categorical data on the basis of the characteristic like sex, religion color, etc.
- Ordinal scale : Used to order the attributes as per their ranks such as First ,Second , Third and so on.
- Interval scale : Used when the difference between any two values can be calculated and has meaning such as Fahrenheit scale to measure temperature.
- Ratio scale : It accommodates all the qualities of the 3 measures and in addition a "true zero" point. For example : Age.
<em>Positions of runners in a race comes in ordinal scale because we need to order them with their respective rank</em>.
So, the correct option is D. Ordinal
Answer:
the y-intercept is where u start on a graph like where it crosses through the middle line and the slope it the rise and run so rise is how much it goes up and run is how much u go over.
hope this helps.
Answer:
The equation of the circle is (x - 3)² + (y + 2)² = 9
Step-by-step explanation:
The form of the equation of a circle is (x - h)² + (y - k)² = r², where
- h is the x-coordinate center of the circle
- k is the y-coordinate of the center of the circle
- r is the radius of the circle
∵ The center of a circle is (3, -2)
∴ x-coordinate of the center is 3
∴ y-coordinate of the center is -2
∴ h = 3 and k = -2
∵ The radius of the circle is 3
∴ r = 3
→ Substitute them in the form of the equation above
∵ (x - 3)² + (y - -2)² = (3)²
∴ (x - 3)² + (y + 2)² = 9
∴ The equation of the circle is (x - 3)² + (y + 2)² = 9
