For each function f(x,y,z), determine whether its gradient points radially outward from the origin, radially inward toward the o

rigin, radially outward from the z-axis, or radially inward toward the z-axis.
a. f(x, y, z) = 1/x^2+y^2
b. f(x, y, z) = x^2 +y^2
c. f(x, y, z) = 1/ x^2 +y^2 + z^2
d. f(x, y, z) = x^2 + y^2 + z^2

Answer:

Mean = 48.6364

s^2 = 331.8545 -- Sample Variance

s = 18.2169 --- Sample Standard Deviation

Step-by-step explanation:

Given

n = 11

Data: 24, 41 ,25 ,68 ,53 ,83 ,43 ,63 ,56 ,34 ,45

Solving (a): The sample mean

Mean = \frac{\sum x}{n}

So:

Mean = \frac{24 +41 +25 +68 +53 +83 +43 +63 +56 +34+ 45}{11}

Mean = \frac{535}{11}

Mean = 48.6364

Solving (b): Sample variance (s^2)

This is calculated as:

s^2 = \frac{\sum (x - \bar x_i)^2}{n - 1}

Where:

\bar x = 48.6364

So:

s^2 = \frac{(24 -48.6364)^2 +(41  -48.6364)^2 +......................+( 45 -48.6364)^2}{11-1}

s^2 = \frac{3318.54545456}{10}

s^2 = 331.8545

Solving (c): Sample Standard Deviation (s)

This is calculated as:

s = \sqrt {s^2

s = \sqrt{331.8545

s = 18.2169
