Answer:
And we can find this probability with the following difference:
And in order to find these probabilities we can find tables for the normal standard distribution, excel or a calculator.
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the variable of interest of a population, and for this case we know the distribution for X is given by:
Where
and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability with the following difference:
And in order to find these probabilities we can find tables for the normal standard distribution, excel or a calculator.
Answer:
The answer is 4 to 5
Step-by-step explanation:
The ratio 36 to 45 simplified is 4 to 5
36 divided by 9 = 4
45 divided by 9 = 5
3/4 x=576
x=576 x 4/3=2304/3=$768 price of laptop. $768 x .06 tax=46.08 add to 768=$814.08 for the total cost of the laptop
