The area of the shaded region is the square subtract the circle. The radius of the circle is the diameter/2
Area of circle= pi x radius x radius
=3.14 x 5 x 5 = 78.5
Area of the square = side x side
= 10 x 10 = 100
Area of shaded 100 - 78.5 = 21.5
And don’t forget the unit of measurement (meters)
Answer:
Option 4 : 
Step-by-step explanation:
<u>See the attached figure:</u>
To find the vertices of the feasible region, we need to graph the constraints, then find the area included by them, then calculate the vertices which is the intersection between each two of them.
As shown, the shaded area represents the solution of the constraints
So, the vertices of the feasible region are:

Answer:
-3b - 21
Step-by-step explanation:
You have distribute the -3 to both b and 7. So, you would have to multiply the -3 to both b and 7.
Answer:
Step-by-step explanation:
y=x²+4x+4
or y=(x+2)²
or y=(x+2)²+0
vertex Is (-2,0)
Answer:
7.1 weeks to 68.4 weeks
Step-by-step explanation:
Chebyshev's Theorem states that:
75% of the measures are within 2 standard deviations of the mean.
89% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 38.1
Standard deviation = 10.1
Between what two search times does Chebyshev's Theorem guarantee that we will find at least 89% of the graduates
Between 3 standard deviations of the mean.
So from 38.1 - 3*10.1 = 7.8 weeks to 38.1 + 3*10.1 = 68.4 weeks
