Answer:
Step-by-step explanation:
We have been given an equation:
y=5x+3
The above equation is the equation of line
If we compare the given equation with general equation of line which is y=mx+c
Where. m is the slope of line.
Here on comparing we get
m=5 and c=3
To find x-intercept put y=0
Its x-intercept is (-0.6,0)
To find y-intercept put x=0
Its y-intercept is (0,3)
Solution :
a).
Now, if X = Y, then :
Then, E[X|Y] = x = y
So,
= 0
Therefore, this statement is TRUE.
b). If X = Y , then Var (X) = Var (Y)
And as Var (X|Y) = 0, so Var (X|Y) ≠ Var (X), except when all the elements of Y are same.
So this statement is FALSE.
c). As defined earlier,
So, this statement is also TRUE.
d). The statement is TRUE because .
e). FALSE
Because,
Answer:
Step-by-step explanation:
GCF = Greatest common factor.
For example: 6 is the GCF of 12 and 18.
The given expression:
It can be written as
Taking out common factor , we get
Hence,
<em>Find the domain by finding where the function is defined. The range is the set of values that correspond with the domain.</em>
<em>Domain: (−∞,∞),{x|x∈R}</em>
<em>Range: [3,∞),{y|y≥3}</em>
