Answer:
a)59.125, b)67.5, c)None
Step-by-step explanation:
Mean = All values added up and divided by the number of values

Median = Put all numbers in order from least to most and use the middle one, if there are two, use the mean of those two
. The middle ones are 60 & 75 so 
Mode = The number that repeats more times. In this case none of them repeat.
Answer:
Step-by-step explanation:
your answer is 4,561.593
First we join the two endpoints of the semicircle and that will be the diameter.
And to find the length of the diameter, we have to use distance formula, with one endpoint (3,2) and the other is (-4,-2) .
SO we get

Radius is half of diameter, so the radius is

Formula of area of circle is

So the area of semicircle is

And the other figure is a triangle, with


Therefore, total area is the sum of area of semicircle and area of triangle,
And we will get

Correct option is the third option .
if you show the triangle on the graph i can figure it out, or give me the coordinates of the original triangle, can't really do it without those things
- for line B so the set of equations to have no solutions bc. x+y=2 and so y=2-x
so from x+y=4 will result y=4-x
so this is the right equation for line B so the set of equations has no solutions
