Step-by-step explanation:
We have the following functions:
and
First we find
To find we must add the function f(x) with the function g(x)
Now we find
To find we must subtract the function f(x) with the function g(x)
Answer: D
Step-by-step explanation:
Standard Deviation σ2 =
Σ(xi - μ)2/N
=(1 - 5.3)2 + ... + (9 - 5.3)2/10
=68.1/10
= 6.81
σ = √6.81
= 2.60959767014
B) σ2 =
Σ(xi - μ)2/N
=(3 - 61.7)2 + ... + (99 - 61.7)2/10
=58414.1/10
= 5841.41
σ = √5841.41
= 76.429117488036
C) (1 - 11.4)2 + ... + (1 - 11.4)2/10
=8758.4/10
= 875.84
σ = √875.84
= 29.59459410095
D) (79 - 79)2 + ... + (79 - 79)2/10
=0/10
= 0
σ = √0
= 0

Answer:
True
Step-by-step explanation:
Your Domain is the x value and if x repeats it should only be written one.
Your domains are (0,3,4,4)
So your answer would be (0,3,4)
How many friends are their without the number of friends you cant answer it so the answer is unknown
