Mean of 14,18, 15 17, 5, 14, 13

13.7142

Step-by-step explanation: The mean of a data set is equal to the sum of the set of numbers divided by how many numbers are in the set.

So to find the mean of the data set shown here,

let's begin by adding the numbers.

So we have 14 + 18 + 15 + 17 + 5 + 4 + 13 which is equal to 96.

86 will be divided by the number of numbers in the set which is 7.

So,  96 divided by 7 is equal to 13.7142.

So the mean of the data set is 13.7142.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
