First you need to get rid of the power of 2 by square rooting both sides. And that is it. The answer is: 0.089

**Answer:**

5.6

**Step**** ****by-step explanation:**

3h - 5 = 12

3h = 12 + 5

h = 17/3 = 5.6

**Answer:**

Binomial probability

**Step-by-step explanation:**

For each computer, there are only two possible outcomes. Either they fail, or they do not. The probability of a computer failing is independent from the probability of other computers failing. So we use the binomial probability distribution to solve this problem.

**Binomial probability distribution**

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

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

And p is the probability of X happening.

**In this problem we have that:**

**To find the probability that exactly 20 of the computers will require repair on a given day, one will use what type of probability distribution**

**Answer:**

Range is {3,-1, 15}

**Step-by-step explanation:**
