We want to find the median for the given density curve.
The value of the median is 1.
Let's see how to solve this.
First, for a regular set {x₁, ..., xₙ} we define the median as the middle value. The difference between a set and a density curve is that the density curve is continuous, so getting the exact middle value can be harder.
Here, we have a constant density curve that goes from -1 to 3.
Because it is constant, the median will just be equal to the mean, thus the median is the average between the two extreme values.
Remember that the average between two numbers a and b is given by:
(a + b)/2
So we get:
m = (3 + (-1))/2 = 1
So we can conclude that the value of the median is 1, so the correct option is the second one, counting from the top.

Answer:
Definition: The enclosing boundary of a curved geometric figure, especially a circle.
Step-by-step explanation:
The age of the van owned = 12 years
The age of the truck owned = 29 years
Step-by-step explanation:
Here, the given question is INCOMPLETE.
Laura takes very good care of her vehicles. She owns a blue van and a red truck. Although she bought them both new, she has owned the truck for 17 years longer than she has owned the van. If the sum of the ages of the vehicles is 41 years, how old is the van and how old is the truck?
Let us assume the number of years Laura has owned the van = S years
So, according to the question:
The number of years she has owned truck = S + 17 years
Now, Sum of the age of ( Truck + Van) = 41 years
⇒ (S + 17 years) + (S years) = 41 years
or, 2 S + 17 = 41
or, 2 S = 4 1 -1 7 = 24
or, S = 24/2 = 12 years
or, S = 12 years
Hence the age of the van owned = 12 years
The age of the truck owned = S + 17 = 12 + 17 = 29 years
14/8 = 1.75
The scale factor is 1.75 because 8* 1.75 = 14
