The number of ways there are to move from (0, 0) to (7, 7) in the coordinate plane with movements of only one unit right or one unit up accordingly is; 49 while that such that y =x is; 7.
<h3>
How many ways are there to get from (0, 0) to (7, 7) in the coordinate plane with pmovements of only one unit right or one unit up?</h3>
It follows from the task content that the movement intended on the coordinate plane is; from (0, 0) to (7, 7).
The number of ways to move such that movements of only one unit right or one unit up is; 7 × 7 = 49.
The number of ways for which y= x is therefore is; 7 as the movement is diagonal.

M = (y₂ - y₁) / (x₂ - x₁)
Multiply each side by (x₂ - x₁): M/(x₂ - x₁) = (y₂ - y₁)
Add y₁ to each side: y₂ = M/(x₂ - x₁) + y₁
Answer:
---- At least 5 from marketing departments are extroverts
---- All from marketing departments are extroverts
---------- None from computer programmers are introverts
Step-by-step explanation:
See comment for complete question
The question is an illustration of binomial probability where


--- marketing personnel
--- proportion that are extroverts
Using the complement rule, we have:

So, we have:






So, we have:


Recall that:



--- approximated

--- marketing personnel
--- proportion that are extroverts
So, we have:





---------- computer programmers
--- proportion that are introverts
So, we have:




A general polynomial of one variable could have any number of terms. If this is what you were asking for then I hope this helps!
First we swap our x and y variable, so we get
x = 3y + 2
Then, we solve for y
We can first subtract 2 on both sides
x - 2 = 3y
Then we can divide by 3 on both sides to get
x/3 - 2/3 = y
So our final equation is
y = x/3 - 2/3
