Consider x+4=x+8. What values could be substituted for x to make this a true number sentence?

Schach [20]

This looks unusual but let's try it.

x+4=x+8

Let's move the x vales to the left and numbers to the right.

x-x=8-4

0=-4

Hm. This doesn't work, does it?

This equation has no solution. If you believe you typed it wrong, correct it in the comment seciton.

What is the term in sequence is the value 191..... an=2+7(n-1),

Alekssandra [29.7K]

Answer:

28th

Step-by-step explanation:

Put that value into the formula and solve for n.

191 = 2 +7(n -1)

(191 -2)/7 = n-1 . . . . . . . subtract 2 and divide by 7

27 +1 = n . . . . . . . . . . . .add 1

191 is the 28th term in the sequence.

Assume that there is a 8% rate of disk drive failure in a year. a. If all your computer data is stored on a hard disk drive wit

romanna [79]

Answer:

0.9936 = 99.36% probability that during a year, you can avoid catastrophe with at least one working drive

Step-by-step explanation:

For each disk, there are only two possible outcomes. Either it works, or it does not. The probability of a disk working is independent of any other disk, which means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

Assume that there is a 8% rate of disk drive failure in a year.

So 100 - 8 = 92% probability of working, which means that $p = 0.92$

Two disks are used:

This means that $n = 2$

What is the probability that during a year, you can avoid catastrophe with at least one working drive?

This is:

$P(X \geq 1) = 1 - P(X = 0)$

In which

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 0) = C_{2,0}.(0.92)^{0}.(0.08)^{2} = 0.0064$

$P(X \geq 1) = 1 - P(X = 0) = 1 - 0.0064 = 0.9936$

0.9936 = 99.36% probability that during a year, you can avoid catastrophe with at least one working drive
