The surface is parameterized by

and the normal to the surface is given by the cross product of the partial derivatives of
:

It looks like you're given

Then the normal vector is

Now, the point (2, 2, 0) corresponds to u and v such that

and solving gives
, so the normal vector at the point we care about is

Then the equation of the tangent plane is



Answer:
B. -7 + 8n
Step-by-step explanation:
-3.5(2 + -3n) + -2.5n = 0
(2 * -3.5 + -3n * -3.5) + -2.5n = 0
(-7 + 10.5n) + -2.5n = 0
0.5n + -2.5n = 8n
-7 + 8n
The probability is 7/10 or 70% that a randomly selected student does not receive some form of government-sponsored financial aid
Total number of students in the small private college = 800
Number of students who receive some form of government-sponsored financial aid = 240
Number of students who did not receive government-sponsored financial aid = 800 - 240 = 560
Computing the probability using the formula, we get the following:
The probability that a randomly selected student did not receive government-sponsored financial aid = Number of students who did not receive financial aid/Total number of students in the college
= 560/800 = 7/10 or 70%
