Median: 2 goals

Mean: 2 goals

Step-by-step explanation:

Let's go over the definitions of the terms "median" and "mean",

Median: The number in the middle of the data; the value in the middle of a range of values

Mean: The average number between all values in a range of values

To find the median, let's first look at all the numbers in the data. We're trying to find the median conceded goals, so the numbers are:

0

1

2

3

4

Now, let's find the middle number. Cross off 0 and 4, 1 and 3, and we are left with 2. 2 is the median.

To find the mean, or the average, we must add all of the numbers together, and then divide that number by the amount of terms. There are 5 terms. Let's review them again.

0

1

2

3

4

Add them together to get 10. Then, since there are 5 values, divide by 5. 10/5 = 2. So, the mean is 2.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
