Answer:
What ever it is, it should be minus. a = - 2
Step-by-step explanation:
Givens
v1 = - 2
v2 = - 10
t = 4 seconds
formula
a = (vf - vi)/t
Solution
a = (-10 - (-2)) / 4
a = (-10 + 2) / 4
a = (-8)/4
a = -2 m/s^2

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
Step-by-step explanation:
x is the number.
(x + 5) - 2x : the sum of the number and 5 decreased by twice the number.
or simplified without the brackets
x + 5 - 2x = 5 - x
it is not clear if you need the general expression showing both conditions (the first up there), or the then simplified result
5 - x
