Answer:
Composite area is 400+157=557
or 400 + 50pi
Step-by-step explanation:
First find the area of the square
A=s*s A= 20*20
Area of the square portion is 400
then find the area of the semicircle- we know the diameter of the circle is 20, so the radius is 10.
so
Composite area is 400+157=557
or 400 + 50pi
Your answer is B. This is because the mode is the number that is repeated the most amount of times. In this data set, $650 is repeated while the other numbers are only said once.
Slope = -1, hope this helps :)
