Answer:
B. 44°
Step-by-step explanation:
Central angle = 3x + 10°
Inscribed angle = 2x - 17°
Now
Central angle = 2 * inscribed angle
( Central angle is double of the inscribed angle standing on same arc)
3x + 10° = 2 ( 2x - 17°)
3x + 10° = 4x - 34°
4x - 3x = 34 ° + 10°
x = 44°

Answer:
The probability of a dart hitting the target in the yellow zone is 0.16 or 16%
.
Step-by-step explanation:
Given:
Four concentric circles.
Radius of center circle, r = 4/2 = 2 cm
Radius of the yellow circle, R = 2+4 =6 cm
We have to find the probability that it will hit a point in the yellow region.
Formula to be used:
Probability (P) :
⇒
So,
Lets find the area of the yellow zone;
⇒ Area (yellow zone), = Area of yellow circle - Area of the black circle
⇒
⇒
⇒
⇒
⇒
⇒ cm^2
Now,
⇒ Area of the entire target, A1:
⇒
⇒ <em> ...R1=14 cm</em>
⇒ cm^2
Probability:
⇒
⇒
⇒
⇒
In terms of percentage it is
The probability of a dart hitting the target in the yellow zone is 0.16 or 16%
