The two 3s have different place values. The 3 on the left is in thousands place while the 3 on the right is in the ones place. we can also look at this vc by separating each digit ( 3000 + 400 + 50 + 3)
while the digits are the same, their place determines the value
All the components in the state vector need to sum to 1. You're given that component corresponding to state 1 is 0.2, and that the component for state 3 is 0.
That leaves states 2 and 4, for which you're told that the component for state 2 is four times as large. If

is the component for state

, then you have

which means

. So the state vector is

.
It looks a little less than 1/2 or 4/8, so probably 3/8 of the gas is left.
You put 3 shapes together I believe
Answer:
right triangle
Step-by-step explanation:
We know that the total angles of the triangle are 180 degrees:
(x) + (4x-10) + (2x+15) = 180
7x - 10 + 15 =180
7x + 5 = 180
7x = 180 - 5
7x = 175
x = 175÷ 5 = 25
Now we calculate each angle
x=25
4x-10= (4*25) -10=100-10=90
2x+15=(2*25)+15=50+15=65
Because we have a right angle, then the triangle is right triangle
