Answer:
18 ft^2
Step-by-step explanation:
This quadrilateral is a parallelogram.
Area = base × height
= 6 × 3
= 18 ft^2
Answer:
the slope is undefined
Step-by-step explanation:
x=-1
Answer:
Please add a picture!
Step-by-step explanation:
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.

Frankly, substitution is almost always a better method. Graphing is a very precise and time consuming process where you have to calculate several..
