Find the median for the following set of scores: 2,7,9,4,5, 3, 0, 6

4.5

Step-by-step explanation:

First, you have to put them in order from least to greatest

0,2,3,4,5,6,7,9

Now we start crossing out the ends on both sides until we get to one in the middle.

2,3,4,5,6,7

3,4,5,6

4,5

Now, we will add these two and then divide them by 2

4+5=9

9÷2=4.5

step by step resolutions

1) n+n+1+n+2=51

3n+3=51

3n=48

n=16

the three numbers are 16, 17 and 18.

2) x+15=4x

3x=15

x=5

3) the two digits are x and y.

y=3x

(10x+y)+(10y+x)=88

y=3x

11x+11y=88

y=3x

x+y=8

x+3x=8

x=2

the original number can be either 28 or 82.

4) n+(n+2)+(n+4)=48

3n+6=48

3n=42

n=14

the numbers are 14, 16 and 18.

5) y=x+3

10y+x+10x+y=143

y=x+3

11x+11y=143

y=x+3

x+y=13

x+x+3=13

2x=10

x=5

the original number can be 57 or 75.

hope this !
