2. Is the mean of the age distribution closer to 15, 20, or 25 years? Explain your answer.
1 answer:
Answer:
the mean of the age distribution is 20
Step-by-step explanation:
Question is
A local utility company wanted to gather data on the age of air conditioners that people have in their homes. The company took a random sample of 200 residents of a large city and asked if the residents had an air conditioner, and if they did, how old it was. Below is the distribution in the reported ages of the air conditioners.
the graph is attached below
find the mean of the age distribution closer to 15, 20, or 25 years
In the given graph the distribution is centered at 20
So the mean of the age distribution is 20

Answer:
Refer the attached figure.
Step-by-step explanation:
Given : System of equation
To find : Which graph represents the solution to the given system?
Solution :
Equation plotted with a red line passing through (-1,0) and(0,4).
Equation plotted with a blue line passing through (0,-3) and(0.75,0).
As their slopes are equal i.e. m=4.
So, the equation of lines are parallel.
There is no solution of the equations.
Refer the attached figure of the equations.
