Answer:
x = 28
Step-by-step explanation:
21/
= 6/8
cross multiply: 21 x 8 = 6 x
Combine like terms: 168 = 6
Divide both sides by 6: 28 =
Answer:
10%
Step-by-step explanation:
Answer:
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.
Subtract three from both sides to get:
Square both sides to get:
Subtract r to get:
Factor to get:
(r-9)(r-4)=0
The solutions to this equation are 9 and 4.
