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:
3 h(x) = 4 sin(2x + π) + 3
Step-by-step explanation:
Y=mx+c
1) FIND M
Perpendicular lines formula
m1 x m2 = -1
- gradient of the lines multiplied together equals to -1
Substitute
m1 x m2 = -1
12 x m2 = -1
m2 = -1/12
m2 = -0.083
2) FIND C
Now we know m, y and x, so we can find c.
(x,y) -> (10,-5)
y=mx+c
-5=-0.083*10+c
-5=0.83+c
-5-0.83=c
c=-5.83
So the equation would be
y=-0.08x+5.83
In the attached diagram you can see the graph of the function 
As you can see graph is:
1. increasing from x = −2 to x = −1
2. decreasing from x = 0 to x = 1
3. decreasing and then increasing from x=1 to x=2
4. increasing from x=2 to x=4.
Answer: correct choice is B.
I believe that it’s the first one
