Tutor: Hi! I am now working on your question and you will soon see me writing on your drawing board.
Tutor: Hi, how are you?
Student: Good
Student: Is the question clear
Tutor: Aye, it is..
Student: Ok
Student: Cool
Tutor: There you go!
Tutor: That's our resultant matrix
Student: Thanks
Tutor: No prob
Student: Would u happen to know this one
Student: Use a Venn diagram to answer the question.
A survey of 137 college students was done to find out what elective courses they were taking. Let A = the set of those taking art; B = the set of those taking basket weaving; and C = the set of those taking canoeing. The study revealed the following information:
n(A) = 45; n(B) = 55; n(C) = 40;
n(A ∩ B) = 12; n(A ∩ C) = 15
Tutor: Sure, I know it... but the question does not seem to be complete
Student: N(B ∩ C) = 23;
n(A ∩ B ∩ C) = 2.
How many students were not taking any of these electives?
Student: Thats the rest
Tutor: Ok, got it...
Tutor: There's a direct formula.. i shall use that.. or would you like me to show you how it's done using Venn diagrams?
Student: Just checking answer
Student: I got 10
Tutor: Alright... just a min please
Tutor: Ans ----> 45
Student: Ok
Tutor: Oh sorry... one min
Tutor: Yup, 45 it is..
Tutor: Need the work?
Student: No
Tutor: K
Student: Find the value(s) of the function, subject to the system of inequalities.
Find the maximum and minimum of subject to:
0 ≤ x ≤ 5, 0 ≤ y ≤ 8, 4x + 5y ≤ 30, and
Student: Z=10x-24y
Student: Is after the subject to:
Student: And the and is 4x+3y<20
Student: Is that clear?
Tutor: Ok, I am to find the max n min value of which function??
Tutor: Z = 10x - 24y, right?
Student: Yes
Student: I got 50,-144
Student: Find the value(s) of the function, subject to the system of inequalities
Tutor: I need a min please..
Student: Ok
Tutor: So, there are 4 conditions?
Student: Ok
Student: Yes
Tutor: -144 is the min value... that part is true..
Student: And 0?
Tutor: With x=0,y=6, we satisfy all conditions...
Student: Ok
Tutor: 50 will not be true am afraid...
Student: Very cool mate thanks
Student: Student has ended this session. This question is automatically marked as done.
Tutor: Because with x=5,y=0, we get z=50 but here the condition 4x + 3y < 20 will not be satisfied
Tutor: Hi, how are you?
Student: Good
