Answer:
y =
<em>x</em> + 70
or
y = 70 
(They're both the same equation, whichever one you prefer you can use!)
-1/4
- for a negative slope
rise over run
rises 1
runs 4
Answer:
I.
A is a 4 x 5 matrix => A: U -> V, dim U = 5, dim V = 4
Null space is exactly two dimensional plane
dim null (A) = 2
II.
Rank A = dim U - dim Null A = 5 - 2 = 3
III.
Number of linearly Independent columns of A is the rank of A = 3
IV.
Yes, The system Ax = b has no solution sometimes as range of A \neq V
V.
Yes,Sometimes Ax = b has a unique solution
VI.
Yes, sometimes Ax = b has infinitely many solutions
Answer:
Step-by-step explanation:
Given that:
X(t) = be the number of customers that have arrived up to time t.
... = the successive arrival times of the customers.
(a)
Then; we can Determine the conditional mean E[W1|X(t)=2] as follows;




Now 
(b) We can Determine the conditional mean E[W3|X(t)=5] as follows;

Now; 
(c) Determine the conditional probability density function for W2, given that X(t)=5.
So ; the conditional probability density function of
given that X(t)=5 is:

Answer:
- 2 < x < 16
- 3 < x < 19
- 14 < x < 18
- 4 < x < 16
- 13 < x < 47
- 0 < x < 10
- 1 < x < 7
Step-by-step explanation:
The minimum third side is the difference of the given sides; the maximum third side is their sum.
If you like, you can have a spreadsheet calculate these for you. That seems like more work than just doing them in your head.
