The mean of the distribution of the sampling mean is the same as the mean of the population, 18.6.
All you do is subtract what John is spending from the amount he has. 20.43-15.39= $5.04

- First find the area of the whole circle
The equation is :
πr^2
Substitute the radius in:
π(5)^2
Solve:
Area of full circle = 25π
(Note : leave this answer in terms of 'pi' so it is easier to handle
Next, find the area of the sector
The equation for this is:
(angle/360) x πr^2
Substitute the values in:
(80/360) x π(5)^2
Solve :
Area of sector = (50/9)π
Now, find the area of the triangle:
1/2 absinC
Substitute the values in:
1/2(5)(5) x sin(80) = 12.31009691
Subtract this answer from the area of the sector
Answer = 5.14319607
Subtract this from the area of the whole circle
Answer = 73.39662073
To the nearest tenth, that would be 73.4 cm^2

Answer:
5x-y=50
Step-by-step explanation:
we know that
If two lines are parallel, then their slopes are the same
In this problem
The west edge of the basketball court is located on the line
y = 5x + 2 -----> the slope of this line is m=5
If the east edge cannot intersect with the west edge
then
east edge and west edge must be parallel
so
The east edge could be
5x-y=50
because
y=5x-50 ----> the slope of this line is m=5
