The pe clasd has 12 boys and 8 girls what is the maximum number of teams that the teacher can divide the class into so that each team has an equal number of boys and girls the greatest common factor of the numbers of girls and boys

4

Step-by-step explanation:

We are given that a PE class has 12 boys and 8 girls. The teacher needs to divide in maximum number of teams so that each team has an equal number of boys and girls.

For this, we will factors of 12 and 8 and their greatest common factor.

12 = 4 × 3 = 2 × 2 × 3

8 = 4 × 2 = 2 × 2 × 2

The greatest common factor is 4, therefore the maximum number of teams with equal number of boys and girls is 4.

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.

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
