Answer:
X is discrete random variable
Step-by-step explanation:
Consider the provided information.
Horses are housed in pasture, pipe pens, or barn stalls at a local horse barn.
Let X be the number of horses that are housed in the pasture, pipe pens, or barn stalls.
Discrete random variable: If the number of values is finite then C is discrete in nature.
Random variable; If the variable can take any value between two defined value then X is called continuous in nature.
Here the number of horses are finite and we can count them easily.
Thus, X is discrete random variable.

Answer:
Volume of a sphere is 4/3(pi r ^3)
You were given d = 10 so r = 5
Answer:
If two figures are similar, then the correspondent sides are related by a constant factor.
For example, if the base of one side of one of the figures has a length L, then the correspondent side of the other figure has a length k*L where k is the scale factor.
Let's start with the two left triangles.
In the smaller one the base is 5, and the base of the other triangle is 15.
Then we will have:
15 = k*5
15/5 = k = 3
The scale factor is 3.
Then we will have that:
a = scale factor times the correspondent side in the smaller triangle:
a = k*3 = 3*3 = 9
a = 9
For the other two triangles, the base of the smaller triangle is 12, while the base of the larger triangle is 20.
Then we will have the relation:
12*k = 20
k = (20/12) = 10/6 = 5/3
The scale factor is 5/3
This means that the unknown side b is given by:
b*(5/3) = 15
b = (3/5)*15 = 3*3 = 9
b = 9.
