Answer:
<BOD = 120°
<EOC = 200°
<AOC = 135°
Step-by-step explanation:
Given:
<DOE = 115
°
<AOB = 60
°
<BOC = 75
°
<AOB + <BOD = 180°
so
<BOD = 180° - <AOB = 180° - 60° = 120°
<EOC = <EOA + <AOB + <BOC
As you know <EOA + <DOE = 180°
so
<EOA = 180° - <DOE = 180° - 115° = 65°
Now you find
<EOC = <AOE + <AOB + <BOC
<EOC = 65° + 60° + 75° = 200°
and
<AOC = <AOB + <BOC = 60° + 75° = 135°
Circumference of Circle=C, =2(pi)(radius)
Radius of Circle=r
Side of square=x
f(x)=area of circle
g(r)=area of square
16 feet=C+4x
C=16-4x
2(pi)(r)=16-4x
2(pi)(r)=2(8-2x)
(pi)(r)=8-2x
r=(8-2x)/(pi)
x=(8-(pi)r)/2
f(x)=(pi)(r^2)
f(x)=(pi)((8-2x)/(pi))^2
f(x)=((8-2x)^2)/(pi)
f(x)=((64-32x+4x^2))/(pi)
g(r)=((8-(pi)r)/2)^2
g(r)=((64-16(pi)r+(pi)^2(r^2))/4
Answer:
7,14,21,28,35,42,49 are all dividible by 7. That are 7 Numbers. However we are looking for All the Numbers that are not a multiple of 7.
So 50-7=43.
There are 43 Numbers which are not a multiple of 7.
So 43/50=0.86
The probability is 0.86 or a 86% chance that the generator will select a Number which is not a multiple of 7.
