The school hired a guest speaker to come and talk to the students for an evening presentation. The school advertised the presentation to all community members and guaranteed the speaker that attendance would be at least 1,000 people. The school is selling student tickets for $4 and non-student tickets for $6. If the school also guaranteed the total ticket sales would be at least $4,800, what is the minimum income the speaker can make and how many of each type of ticket was sold? Assume the speaker will receive $2.50 for every student ticket sold and $4.50 for every non-student ticket sold.

the student tickets would sell for 45K which is also 45,000 dollars, its easy multiplication using the butterfly method.

Step-by-step explanation:

i am confused on how the speaker would get anymore than 2.50 since they did not give a time, so there is one answer for you, i am sorry i can not solve one part of your equation, but i hope this helps!

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
