The 3 inside angles of a triangle need to equal 180

you have 80 +60 = 140

so 51+x has to equal 180-140 or 40 degrees

51+x = 40

subtract 51 from each side
x = 40 - 51
x = -11

Just add up all 60 + 80 + 51 = 191.

191 - (-11) = 180 which is the number we would want to get.

(-11) would then because your answer as we do 180 + (-11) it would equal the sum of 191 which would be all the angles together.

Your answer: = (-11)

Let x and y be independent each uniformly distributed on {1,2,...,n} find p(x < y )
bulgar [2K]
If we draw the contingency table of x (vertical) against y (horiz.), we have a square.
For n=4, we have   (legend:  < : x<y   = : x=y   > : x>y

y      1  2  3  4
x
1      = <  <  <
2      > =  <  < 
3      >  >  = <
4      >  >  >  =

We see that there are n(n-1)/2 cases of x<y out of n^2.
Therefore, 
p(x<y)=n(n-1)/(2n^2)=(n-1)/(2n)

However, if the sample space is continuous, it will be simply p(x<y)=1/2.

The distance, y, in miles, traveled by a car for a certain amount of time, x, in hours, is shown in the graph below:
Kazeer [188]
Answer: The correct answer is the last choice.

In the first segment of the trip, the car goes from 0 to 2 hours and the line is moving up. Therefore, it traveled for 2 hours.

In the second segment, the line went straight horizontal for 1 hour. That means the distance didn't change, in other words it didn't move.

In the last segment, it moved up again for 2 hours.
