A. 1 (or 1x or x in the equation)

B. 1 (or (0, 1) on the graph)

C. y=x+1

Step-by-step explanation:

The formula for slope is rise over run, or rise/run. This means that you take the amount a line rises (or decreases) between 2 points. The run is the distance on the x-axis (___ looking line) that separate the two points. The y-intercept is going to be the point that is on the y-axis, the vertical line (| looking line). To find the equation, you take the slope, multiply that to x, and add the y-value of the y-intercept.

The number of goals scored by 7 players in a soccer season was 8, 6, 4, 8, 3, 1, and 5.
Find the mean number of goals scored by the 7 players.

The mean number of goals is ___.

Answers

the answer is 5. If you need help remembering how to find the mean, you add up all the numbers given and then divide it by how many numbers there are so for example

8+6+4+8+3+1+5= 35

35 divided by 7

=5

The mean number of goals scored by the 7th player is 5 goals.

What are mean, median, and mode?

The three main methods for identifying the average value of a set of integers are mean, median, and mode.

Adding the numbers together and dividing the result by the total number of numbers in the list yields the arithmetic mean.

The middle value in a list that is arranged from smallest to greatest is called the median.

The value that appears the most frequently on the list is the mode.

Given, The number of goals scored by 7 players in a soccer season was 8, 6, 4, 8, 3, 1, and 5.

Therefore the mean no. of goals scored by the 7th player is the sum of all the goals scored by 7 players divided by the no. of player which is,

= (8 + 6 + 4 + 8 + 3 + 1 + 5)/7.

= 35/7.

= 5.

So, the mean no. of goals scored by the 7th player is 5.
