Answer:
And we can find this probability with this difference:
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 temperatures 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 this difference:

The answer would be 27.6 that is my answer
The area of the first rectangle would be 18cm² and the area of the second rectangle would be 12cm².
<h3>How to calculate the area of a rectangle?</h3>
To calculate the area of a rectangle we must apply the following mathematical formula:
According to the above, to calculate the area of the rectangles we must multiply the length of the side by the base as shown below. We must also take into account the table that will give us the value of X that we do not know:
- 3cm × 6cm = 18cm²
- 2cm × 6cm = 12cm²
Finally, to know how much the area of both rectangles adds up, we add both values:
12cm² + 18cm² = 30cm²

Answer:
I dont think this question is formated correctly. i does not equal to -1. However, If you are wondering about i^-3. it is -i. Otherwords it is D. Hope this helped.
