The answer is c 16. Square cm
You simply divide 78 by 3, so the answer will be 26.
Answer:
Correct option: c)
radius = 6 inches
Step-by-step explanation:
The complete arc of a circumference has 360 degrees, and the length is 2*pi*radius
Knowing this, we can use a rule of three to solve this problem:
144 degrees - > 15 inches
360 degrees -> 2 * pi * radius
144/360 = 15/(2pi*radius)
2pi*radius = 360 * 15 / 144
radius = 37.5/(2pi)
radius = 5.9683 inches
Rounding to nearest whole number, we have radius = 6 inches
Correct option: c)
Answer:
The probability is 0.1312
Step-by-step explanation:
Here, let us set up a binomial system
From the question, 54% ride a bike
Let p = people that rides a bike
54% = 54/100 = 0.54
p = 0.54
q = 1 - p = 1 -0.54 = 0.46 ( 46% do not ride bikes)
Now, for the binomial system, we have
P(X = 15) = 30 C 15 • p^15•q^15
We have;
30 C 15 * 0.54^15 * 0.46^15
= 0.131200268998
The probability is 0.1312
