The list below shows the ages of the first 20 fans to arrive at a professional basketball game. display the fan age data on this stem-and leaf plot.

Step-by-step explanation:

First we will arrange the ages of fans of the basketball game in the increasing order.

9, 11, 14, 14, 16, 25, 25, 27, 28 30, 33, 35, 35, 37, 38, 39, 42, 46, 47, 60

Part A. Now we will make stem-and-leaf plot

0  |  9

1   |  1, 4, 4, 6

2  |  5, 5, 7, 8

3  |  0, 3, 5, 5, 7, 8, 9

4  |  2, 6, 7

5  |

6  |  0

Part B.

Frequency table

Age           Number of Fans

0 - 9                  1

10 - 19               4

20 - 29             4

30 - 39             7

40 - 49             3

50 - 59             0

60 - 69             1

what’s the question?

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
