Name Sales Patrick 8 Jeffrey 12 Robin 7 Sally 15 Manuel 4 Ming 10 Jesse 12 Mark 17 Jenna 16 The owner of a car dealership keeps track of the monthly car sales for the salespeople at the dealership. What is the median number of cars sold?

Median of number of cars sold is 12.

Step-by-step explanation:

Given:

Name  Patrick    Jeffrey  Robbin  Sally  Manuel  Ming  Jesse  Mark Jenna

Sales    8                12        7             15        4         10        12        17       16

We need to find the median number of cars sold.

Solution.

First we will arrange the sales in ascending order.

We get;

Sales of car in ascending order = 4,7,8,10,12,12,15,16,17

Given:

Number of data in the sets = 9

Now to find the median.

Median is equal to number of data in the sets plus 1 divided by 2 term.

framing in equation form we get;

median =

n ⇒ Number of data in the sets.

median =

Hence the fifth data in the set is the median of the number of cars sold.

So we can say that;

Median of number of cars sold is 12.

no ,sorry if you needed it but you can ask and try to see if any one will anwser ,

step-by-step explanation:

by good luck mark me as brainliest

have a nice day

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
