a) In how many games were zero
goals scored?
Number of games
b) Altogether, how many goals did
the team score in the 18 games?
c)What was the median number
of goals that the
team scored?
Answer:
a) 1 game
b) 41 goals
c) median = 2
Step-by-step explanation:
a)
As we can see in the line graph, where we have the 0 for the number of goals scored, the graph indicates only 1 in the number of games, so we have only 1 game where no goals were scored.
b)
To find the total number of goals scored, we multiply the goals scored by the number of games for that score, and then sum them all:
total goals = 1*0 + 4*1 + 5*2 + 6*3 + 1*4 + 1*5 = 41 goals
c)
To find the median, we put all the goals in crescent order, and then find the value in the middle. As we have 18 games, the middle value will be an average of the 9th and 10th terms.
We have 1 number 0, 4 numbers 1 and 5 numbers 2 in the beginning, so for these 10 numbers, the 9th and the 10th are the score 2, so the median is 2.
a) One game
b) The total goal scored in the games is 45
c) The median goal is 3
A line graph is a type of chart that displays data points using straight line segments. It is often used to illustrate trends or changes in data over continuous intervals.
a) One game
b) Total goals all together
4*1 + 5*2 + 6*3 + 1*4 + 1*5
= 4 + 10 + 18 + 4 + 9
= 45 goals
c) Median is the middle goal when arranged in increasing or reducing order.
Median = n + 1/2
Where
n is total number of event, in this case in 45
median = 45 +1/2
= 46/2
= 23rd goal
When counted from the least goal to the highest goal, the 23rd goal is 3

The value of 8n is 16.
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations that are formed according to rules which are dependent on the context.
n=2
8n
Substitute the value of n is 8n,
Therefore, the value of 8n is 16.
