Use lagrange multipliers to find the shortest distance, d, from the point (4, 0, −5) to the plane x y z = 9.

zlopas [31]

One function you would be trying to minimize is
f(x, y, z) = d² = (x - 4)² + y² + (z + 5)² 

Your values for x, y, z, and λ would be correct, but 
d² = (20/3 - 4)² + (8/3)² + (-7/3 + 5)² 
d² = (8/3)² + (8/3)² + (8/3)² 
d² = 64/3 
d = 8/sqrt(3) = 8sqrt(3)/3

In a manufacturing plant that produces new computers, a 0.15 probability exists that a computer will be defective. if five compu

Sindrei [870]

The probability that all of them will be defective is 0.0000759375

Explanation

The general Binomial Probability formula is....

$P= ^nC_{r}*p^r*(1-p)^n^-^r$ , where p is the probability of success, n is the total number of trials and r is the desired numbers of trials.

Given, the probability that a computer will be defective is 0.15 , so p = 0.15

Five computers are manufactured and we need to find the probability that all of them will be defective. That means, n = 5 and r = 5

Now according to the above formula....

$P= ^5C_{5}*(0.15)^5*(1-0.15)^5^-^5 \\ \\ P= 1*(0.15)^5* (0.85)^0\\ \\ P=(0.15)^5 =0.0000759375$

So, the probability that all of them will be defective is 0.0000759375
