Answer:
120
Step-by-step explanation:
so we have 16 teams and we are chosing two

Answer:
See Explanation
Step-by-step explanation:
We see that . We can use this to find that .
Let the number of professors be x.
Hence, number of students = 16x
Professors + students = 17000
x + 16x = 17000
17x = 17000
x = 1000
Thus,
Number of professors = 1000
Number of students = 1000 * 16 = 16000
Since the line is horizontal (flat) the gradient, m, is zero (0). c is the y-intercept and in this case -4.
Equation of a line: y = mx + c
since m = 0 then,
y = c = -4
therefore y = -4 ...is the equation.
