Answer:
A) 4/15
Step-by-step explanation:
There are 15 total numbers that becomes 15 total possibilities
There are 4 numbers less than 5, so there is a 4 out of 15 chance one of those numbers get picked

Explanation:
An equality can be transformed in a system of equations by making each side equal to a new variable. In this case the variable y was made equal to each side.
See that may find the solution of such system by graphing both functions in a same coordinate system, where the intersection of the functions would show the solution of the system.
I show you that in the attached image. In such graph, the red curve is the function y = x² and the blue function is y = x³ + 2x.
The intersection point is (0,0) meaning that the solution is x = 0, y = 0.
So first, let us say that the inner circle is circle B and the outer circle is circle A. The area of circle A minus the area of circle B gives you the area between them. So, the area of circle A is 14²π = 196π. The circle B's area is 6²π = 36π. Hence, the area is 160π between both of them. Now, the area of the outer circle as we found is 196π, so the probability that I would choose a point between the outer and inner circle is 160π/196π = 40/49.

Answer:
Step-by-step explanation:
The two given angles add to 180 if the 2 angles that look parallel are parallel.
That means that
17x + 14 + 4x - 2 = 180 Combine like terms
21x + 12 = 180 Subtract 12
21x = 180 - 12 Combine
21x = 168 Divide by 21
x = 168 / 21
x = 8
Therefore 17x + 14 is the angle you want.
<B = 17*8 + 14 = 150.
===================
There's another way to do this.
4x - 2 + <B = 180
4*8 -2 +<B = 180
32 -2 + <B = 180
30 + <B = 180
<B = 180 - 30
<B = 150
