The three interior angles of any triangle add to 180 degress. Therefore,
180-(120 + 40) = the third angle.
So, 20 is the third angle
Answer:
C
Step-by-step explanation:
Given
(3x² + 5x - 8) + (5x² - 13x - 5) ← remove the parenthesis
= 3x² + 5x - 8 + 5x² - 13x - 5 ← collect like terms
= 8x² - 8x - 13 → C
ΔADC and ΔCDB are similar. Therefore the sides are in proportion:
Substitute:
<em>cross multiply</em>
<em>divide both sides by 4</em>
Answer:
Probability distribution vector =
Step-By-Step Explanation
If is the transition matrix for a Markov chain with two states.
be the initial state vector for the population.
In the long run, the probability distribution vector Xm approaches the probability distribution vector .
This is called the steady-state (or limiting,) distribution vector.
To solve for c:
Subtract 19 from both sides of the equation.
-4c=-2
Then divide -4 on both sides
c= +1/2
