If the wheel has a diameter of 15 inches, its radius is half that, or 7.5 inches then.
a full turn, or a full cycle around the wheel, namely around the circle is 360° or 2π radians.
now, in one turn or cycle, it covered an angle of 2π, in 2 cycles it covered 2(2π), in 3 it did 3(2π) and in 4 of course 4(2π).
so, what is the arc's length, whose radius is 7.5 and its central angle is 8π?
well.... you already know that s = rθ, therefore then, s = (7.5) (8π).
Answer: the standard deviation is 2.4
Step-by-step explanation:
The formula for standard deviation is expressed as
s = √npq
Where
p = probability of success
q = probability of failure
n = number of samples
From the information given,
The probability of success, p is given as 0.2. It means that the probability of failure, q will be 1 - p = 1 - 0.2 = 0.8
There were 35 attempts. This means that total number of samples, n is 35
The standard deviation becomes
√35×0.2×0.8 = √5.6 = 2.366
Approximately 2.4
Answer:
0.96
Step-by-step explanation:
Let x = 0. What do you get for y?
This gives you one point.
Then let x = 1. What do you get for y.
This gives you a second point.
