Answer:
B: 10
Step-by-step explanation:
The angle measures are all multiplied by 2.
Answer:
588 square centimetres
Step-by-step explanation:
42*28/2=588
F(x)=x/x²+2
So... f(x)=1/x+2
Therefore:
f(-x)=1/(-x)+2=-1/x+2
Answers:
x = 20
angle A = 65 degrees
angle B = 55 degrees
==============================================
Work Shown:
A+B = 120
(3x+5) + (2x+15) = 120
5x+20 = 120
5x = 120-20
5x = 100
x = 100/5
x = 20
Use this to find both angles
angle A = 3x+5 = 3(20)+5 = 65 degrees
angle B = 2x+15 = 2(20)+15 = 55 degrees
Then note how A+B = 65+55 = 120 to help confirm our answers.
Answer:
Ordinal Variables
Step-by-step explanation:
Ordinal level of variable measurement is the level of measurement that depicts high level of ordered relationship among the variable’s observations.
The ordinal level of measurement indicates an ordering of the measurements.
This type of variable have a meaningful order to them. An example is class grade (with possible values of Excellent, Very Good, Good, Credit, Fair and Poor).
Another example is the education level (with possible values of high school, undergraduate degree, and graduate degree).
