How many solutions does the nonlinear system of equations graphed below
have?
a. one
b. two
c. four
d. zero

Putting two or more equations in a system means to find the set of variables that satisfies all the equations at the same time.

Moreover, the points that satisfy an equation are the points that lay on the graph described by the equation.

So, putting everything together, solving a system means to lay on all the graphs at the same time. In other words, the solutions of a system are the points of intersection between the graphs that represent the functions involved in the system.

In this case, the line and the circumference have two points of intersection, and they are the two solutions of the system.

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
