Answer:
D is correct
Step-by-step explanation:
A graph of that sort will make a perfectly mirrored "V" shape, and with no offset, the bottom point will be on the y axis. This means that the first equation will intercept the y axis at zero, the second will intercept the y-axis at -15.
"A" may seem correct also, as the second graph will intercept the x-axis at -15, but it is not complete, as it will intercept that axis at +15 as well.
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:




In general, a solution of a system in two variables is an ordered pair that makes BOTH equations true. In other words, it is where the two graphs intersect, what they have in common. So if an ordered pair is a solution to one equation, but not the other, then it is NOT a solution to the system
