Answer:

  1.3363

Step-by-step explanation:

The basic idea here is to find an expression for the direction vector between a point on L1 and a point on L2. Then, solve for the points on L1 and L2 that make that vector perpendicular to both lines L1 and L2. (The dot product of direction vectors is zero.) The distance between the points found is the shortest distance between the lines.

__

Let P be a point on L1. Then the parametric equation for P is ...

  P = (6t, 0, -t) . . . . . . origin + t × direction vector

Let Q be a point on L2. The direction vector for L2 is given by the difference between the given points. It is (4-1, 1-(-1), 6-1) = (3, 2, 5). Then the parametric equation for Q is ...

  Q = (3s+1, 2s-1, 5s+1) . . . . (1, -1, 1) + s × direction vector

The direction vector for PQ is ...

  Q -P = (3s+1-6t, 2s-1, 5s+1+t)

The dot product of this and the two lines' direction vectors will be zero:

  (3s+1-6t, 2s-1, 5s+1+t)·(6, 0, -1) = 0 = 13s -37t +5 . . . perpendicular to L1

  (3s+1-6t, 2s-1, 5s+1+t)·(3, 2, 5) = 0 = 38s -13t +6 . . . perpendicular to L2

The solution to these equations is ...

  s = -157/1237

  t = 112/1237

Then (Q-P) becomes (94, -1551, 564)/1237, and its length is ...

  |PQ| = √(94² +1551² +564²)/1237 ≈ 1.3363

The distance between the two lines is about 1.3363 units.

If copies of all your computer data are stored on four independent hard disk​ drives, what is the probability that during a​ yea
Natasha2012 [34]

Answer:

P(Atleast\ 1) = 0.9999992

Step-by-step explanation:

Given

p = 3\% --- rate of hard disk drives failure

n = 4 --- number of hard disk drives

<em>See comment for complete question</em>

Required

P(Atleast\ 1)

First, calculate the probability that the none of the 4 selected is working;

P(none) = p^4

P(none) = (3\%)^4

P(none) = (0.03)^4

Using the complement rule, the probability that at least 1 is working is:

P(Atleast\ 1) = 1 - P(none)

This gives:

P(Atleast\ 1) = 1 - 0.03^4

P(Atleast\ 1) = 0.9999992

The sum of √30 + √50 lies between 12 and 13.

<h3>What is the sum of the numbers?</h3>

The square root of a number can be described as number that when multiplied with itself yields that number.

√30 = 5.48

√50 = 7.07

5.48 + 7.07 = 12.55

The consecutive integers are 12 and 13
