Answer:
Probability is 64%
Step-by-step explanation:
Given the smaller circle which is shaded whose radius is denoted by r and the largest circle whose radius is denoted by R
r = 3 inches
R = 5 inches
Step 1 : To calculate the area of shaded region.
Area of circle = 
⇒ Area =
=
square inches
Step 2 : To calculate the area of larger circle.
Area of circle = 
⇒ Area = 
=
square inches
Step 3 : Calculate the probability that a point chosen from shaded region
Probability = Area of shaded region/Area of larger circle.
=
/ 
= 
= 0.36 = 36%
Step 4 : calculate the probability that a point chosen inside the larger circle is not in shaded region.
Probability = 1 - 0.36
= 0.64 = 64%
Hence the probability is 64%
Answer:
-21
Step-by-step explanation:
Substitute -3 in place of the x
4(-3)-9
-12-9
=-21
The correct answer would be 1.
Answer:
13 hours and 5 minutes is right
<span>Lines c and d must be parallel. This is because angles 10 and 14 are congruent (i.e. the magnitude of their angles is the same). Both angles share line a, which is intersected by line c (which makes up the other side of angle 10, and line d (which makes up the other side of angle 14).</span>
