How do I use the subtraction theorem to write equivalent expressions?
Andreas93 [3]
The subtraction theorem states that for all real numbers, a and b, a-b=a+(-b).
(To subtract, we can add the inverse.)
Thus, we can have the these two equivalent expressions.

3 - 2 = 3 + (-2) = 1\\ \\ 5 - (-2) = 5 + 2 = 7

g The downtime per day for a computing facility has mean 4 hours and standard deviation 0.9 hour. What assumptions must be true
Sedaia [141]

Answer:

To obtain a valid approximation for probabilities about the average daily downtime, either the underlying distribution(of the downtime per day for a computing facility) must be normal, or the sample size must be of 30 or more.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean \mu and standard deviation \sigma, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \mu and standard deviation s = \frac{\sigma}{\sqrt{n}}.

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean \mu = p and standard deviation s = \sqrt{\frac{p(1-p)}{n}}

In this question:

To obtain a valid approximation for probabilities about the average daily downtime, either the underlying distribution(of the downtime per day for a computing facility) must be normal, or the sample size must be of 30 or more.

Stereo has a list price of $150 but is on sale for 20% off the list price what is the sale price of the stereo???
8_murik_8 [283]

Answer:

The correct answer is option A.120

Step-by-step explanation:

Let's start by analyzing the information they have given us.

We know that the stereo has a list price of $ 150, but at the time of payment, we are told that it has a 20% discount.

Now we must find out what the discount was applied to know the final price of the stereo.

One way to calculate the percentage would be multiplying 150 by 0.20

150.0.20 = 30

The discount applied is $ 30, so now we just have to subtract that amount from the original price:

150-30 = 120

Therefore, the correct answer is option A.
