At Oakton, Midlothian, and Jefferson high schools, the long jumpers employ different strategies for competition. At Oakton high

school, the jumpers are very conservative. They are always very careful not to fault, which would result in a jump of 000. But as a result they all jump similar short distances. At Midlothian, the jumpers are very aggressive. They jump as far as they can, but they risk faulting. About half the jumpers get a score of 000 and half jump long distances. (A "long distance" is about twice as far as a "short distance".) At Jefferson, the jumpers strike a balance. They are fairly aggressive, but also careful. As a result, most jump medium distances, while one or two of them fault and jump 000. At Oakton, the median jump will likely be the mean. Suppose 777 out of 151515 jumpers faulted at Midlothian. At Midlothian, the median jump will be the mean. At Jefferson, the median jump will likely be the mean.

Answer:

x = 14

Step-by-step explanation:

f(x) = 10 -  \frac{9}{2} x \\  \\ plug \: f(x) =  - 53 \\  \\  - 53 = 10 -  \frac{9}{2} x \\  \\ \frac{9}{2} x  = 10 + 53 \\  \\ \frac{9}{2} x  = 63 \\  \\ x = 63 \times  \frac{2}{9}  \\  \\ x = 7 \times 2 \\  \\ x = 14
