Answer:

The area lies to the right of the z-score 0.48 means all the values greater than it. This can be calculated on a graphing calculator using the function normCdf, where

  • Lower bound = 0.48
  • Upper bound = 9999
  • Mean = 0
  • Standard deviation = 1

<u>The result would be normCdf(0.48,9999,0,1) ≈ </u><u>0.315614</u>

<u />

The area lies to the left of the z-score 0.79 means all the values less than it. This can be calculated on a graphing calculator using the function normCdf, where

  • Lower bound = -9999
  • Upper bound = 0.79
  • Mean = 0
  • Standard deviation = 1

<u>The result would be normCdf(-9999,0.79,0,1) ≈</u><u> 0.785236</u>

dybincka [34]

The Law of large numbers.

<h3>What is the Law of natural numbers?</h3>

The law of large numbers plays the main role in probability and statistics. It means that if you repeat an experiment independently so many times and average the result, what you get has to be close to the expected value.

An example of the Law of Large Numbers:

Let's assume that you rolled the dice three times and the outcomes were 6, 6, and 3. Then the average result is 5.

So, according to the law of the large numbers, if we roll the dice a large no. of times, then the average result should be closer to the expected value.

It also states that probability and statistics set a sample size that grows, and the mean of the sample size gets closer to the average of the entire population.

How many hours is 3200 seconds <br><br> 3200 s =_____hrs
dezoksy [38]

Dividing by 3,600

1

Determine the number of seconds you have. This information should be given, or it should be a figure you calculated yourself.

For example, you might be converting 2,400 seconds into hours.

ivide the number of seconds by 3,600. Note that there are 3,600 seconds in one hour.[1] So, if you have more than 3,600 seconds, your conversion will be greater than  hour. If you have less than 3,600 seconds, your conversion will be a fraction of an hour.

3

Convert your decimal to minutes. This step is helpful if you are working with a number of seconds equal to less than an hour, so that you can gauge how long a certain decimal is. To convert the decimal to minutes, multiply it by 60.[2]

3200 seconds = 0.88888889 Hours

(rounded to 8 digits)
