Just need to take partial derivatives of the function with respect to x and y then plug in the point coordinates
dT/dx = -38x/(2 + x^2 + y^2)^2dT/dy = -38y/(2 + x^2 + y^2)^2 (only difference is the y in the numerator)
so at point 1,2dT/dx = -38/49 = -0.7755dT/dy = -76/49 = -1.551
Solution: The given problem is a binomial distribution.
The probability that a team member receives a scholarship is 
Therefore, the given problem follows binomial with n = 5 and p = 0.6667
Now the probability that 4 of 5 players selected are on scholarship is:



Therefore, the probability that 4 of 5 players selected are on scholarship is 0.329
Answer:
22%
Step-by-step explanation:
x/100 * 160=35
160x=3500
21.875
hence to the nearest percent: 22%
