Answer:
Your GPA would be 1.5 If you have 6 periods.
Step-by-step explanation:
A = 4 GPA Points
B = 3 GPA points
C = 2 GPA Points
D = 1 GPA Points
F = 0 GPA Points
With that knowledge you calculate 2 (C) + 4 (A) + 3 (B) + 0 (F) + 0 (F) + 0 (F) assuming you have 6 periods which adds up to 9. You divide by the number of periods (6) totaling to 1.5 GPA Points.
Answer:
And we can find this probability using the complement rule:
And in order to find these probabilities we can use 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 lifetime of a certain type of battery 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 using the complement rule:
And in order to find these probabilities we can use tables for the normal standard distribution, excel or a calculator.
