If a dart board was thrown randomly at the dartboard shown below, what is the probability that it will land in the bull’s-eye? T
vampirchik [111]

Answer:

Correct option: C -> 2%

Step-by-step explanation:

To find this probability we just need to divide the area of the bull's-eye circle by the total area of the outer circle.

The area of a circle is given by the equation:

area = \pi * radius^2

The outer radius is 14 cm, so:

outer\ area = \pi * 14^2 = 196\pi\ cm^2

The inner radius is 2 cm, so:

inner\ area = \pi * 2^2 = 4\pi\ cm^2

So the probability is:

inner\ area / outer\ area = 4\pi / 196\pi = 0.02 = 2\%

Correct option: C

What does it mean for a differential equation to be autonomous?
andrew11 [14]
The term "autonomous" refers to an ordinary differential equation that relates the derivatives of the dependent variable as a function *only* of the dependent variable. In other words, the ODE doesn't explicitly depend on the independent variable.

Examples:

y'=y^2-1 is autonomous

y'=y^2-1+x is *not* autonomous
