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:

Answer:
The estimated mean number of rockets hits in the region is 533.
Step-by-step explanation:
We are given the following information,
Number of rocket hits | Observed number of regions
0 | 228
1 | 214
2 | 94
3 | 32
4 | 7
5 | 0
6 | 0
7 | 1
We are asked to estimate the mean number of rocket hits in the region.
The mean or expected value is given by

Therefore, the mean number of rockets hits in the region is 533.
Well, "minus 6 x cubed minus y squared minus 3 x y" translates to:

Then, if we insert the values for x and y, we get:

When we distribute and multiply:

And once we combine like terms:
