Answer: 12.83
Explanation:
The mean is the average of a data set. So, in order to find the mean, we have to add all he values and in this case, we got 77. Then we divide 77 by he number of values we have, which results in 12.83. Therefore, the mean of these numbers are 12.83.
The equation of line perpendicular to given line is:

Step-by-step explanation:
Given equation is:

First of all, we have to find the slope of the given line
So,

Dividing both sides by 2

As the equation is in slope-intercept form, the co-efficient of x will be the slope of the line

As we know that product of slopes of two perpendicular lines is -1
Let m-2 be the slope of line perpendicular to given line

Slope-intercept form is:

putting the value of the slope

Putting the point (3,1) in the equation

Putting the value of b

Hence,
The equation of line perpendicular to given line is:

Multiply both sides by 30
30(15/18) = y
we then multiply 30*15 = 450
450/18 = y
we then get
y = 25
Answer:
y= z-3x/4
Step-by-step explanation:
4y=z-3x
y=z-3x/4
