Maybe it could've been:
3x = 32. Find the value of x.
Hence, you'd do 32 divided by 3 to find the value of x.
The area under the graph of the continuous uniform distribution is 1.
a. The probability that the value will be between 5 and 7 is the area between 5 and 7.

b. The probability that the value will be between 2 and 3 is the are between 2 and 3.
c. The mean is given by:

d. The variance is given by:

The standard deviation is:

Answer:
Step-by-step explanation
Substitute 2y-1 for x in the second equation:
7x + 5y = -66
7(2y-4) + 5y = -66
then solve for y:
14y - 28 + 5y = -66
19y = -38
y = -2
Substitute -2 for y in the first equation:
x = 2y - 4
x = 2(-2) - 4
x = -8
The lines intersect at (-8,-2)
You will need to find the equations of the perpendicular bisector of the two sides and then find the intersection of those two lines. Choose two sides and use midpoint formula to find their midpoints.
