Line D and C shows direct variation because the line goes through the origin my good sir or ma'am :)
Answer:
5(pi) (exactly) or 15.7 (approximately)
Step-by-step explanation:
The length of arc of an entire circle is the circumference of the circle.
The length of arc of a semicircle circle is half of the circumference of the circle.
C = pi * d
For a semicircle:
arc length = 0.5 * pi * d
arc length = 0.5 * pi * 10
arc length = 5(pi)
arc length = 15.7
Just type that in your calculator to get 15.158
Answer:
already know that the radius of the circle is 150
Answer:
0.578
Step-by-step explanation:
If you pick three burritos at random, find the probability of the given event. (Round your answer to three decimal places.)
Given that there are 14 orders at the ratio by of:
6 with hot peppers
8 without hot peppers
At most two have hot peppers.
Binomial Problem with n = 3 ; p(hot) = 6/8
P(0<= x <=2) = 1 - P(x = 3)
= 1 - (6/8)^3
= 1 - ( 3/4 )^3
= 1 - ( 27/64 )^3
= 1- (37/64)
= 1 - 0.421875
= 0.578125
= 0.578
