Answer:
-1
f (x) = -3(x + 5)
Step-by-step explanation:
1) in f(x) = 1/3x-5, replace f(x)= with y= as follows: y = (1/3)x - 5
2) interchange x and y, obtaining: x = (1/3)y - 5
3) solve this result for y: (1/3)y = -x - 5, or -(x + 5). Next, multiply both sides by 3 to eliminate the fraction (1/3): y = -3(x + 5)
4) replace y with the symbol for "inverse of f(x);
-1
f (x) = -3(x + 5)
I think it should be x(ax +b) + c. Not sure though.
Answer: Trapezoidal prism
A figure with 4 sides and a parallel side is called a trapezoid, this is a 3 dimentional trapezoid which is called a trapezoidal prism.

The probability that the randomly selected student chose running is; 12/57
<h3>Solving Probability Questions</h3>
Total number of students = 57
Total number of boys = 24
Total number of girls = 33
Number of Girls that chose football = 17
Number of boys that chose football = 14
Number of students that chose Tennis = 14
Now, number of students that chose running will be;
Number of students that chose running = 57 - (31 + 14) = 12
Thus, probability that a randomly selected student chose running = 12/57
