Step-by-step explanation:
Since we have given that
Total number of members in a sports club = 38
Number of women in the club = 14
Number of women play tennis =10
Number of men play tennis = 8
Since they all play either squash or tennis.
Total number of men in the club is given by
So, number of men playing squash is given by
Number of women playing squash is given by
so, the table is shown below :
Men Women Total
Tennis 16 4 20
Squash 8 10 18
Total 24 14 38
A. 12*x + 2*y = 90
6*x + 2*y = 60
To write system of equation you just need to sum all solo and ensemble acts and make it equal to how much they will last for.
B. Here we can multiply second equation with negative 1 and add it to first equation.
6x = 30
x = 5
now we replace x in any of 2 equations to get y.
30+2y = 60
2y = 30
y=15
Solo acts are 5 minutes long and ensemble acts are 15 minutes long
Answer: Your answer is the third one, a function assigns to each input exactly one output.
If you have a true function, there will only be one output for each input, if you had more than one, it isn't a function.
