Answer:
A
Step-by-step explanation:
z = -3 - 5i
z (i) = i (-3 - 5 i)
z (i) = -3i - 5i^2
z (i) = -3i - 5 (-1)
z (i) = -3i + 5
z (i) = 5 - 3i
Therefore, letter A is the correct answer.

Step-by-step explanation:
The random selection of a blue marble is an illustration of probability
You should expected to pull a blue marble 10 times
<h3>How to determine the expected blue marble?</h3>
The given parameters are:
Blue = 16
Red = 12
Green = 12
The total number of marbles is:
Total = 16 + 12 + 12
So we have:
Total = 40
The probability of selecting a blue marble is:
![P(Blue) = \frac{16}{40}](https://tex.z-dn.net/?f=P%28Blue%29%20%3D%20%5Cfrac%7B16%7D%7B40%7D)
When 25 marbles are selected, the expected number of blue is:
![Blue = n * P(Blue)](https://tex.z-dn.net/?f=Blue%20%3D%20n%20%2A%20P%28Blue%29)
So, we have:
![Blue = 25 * 16/40](https://tex.z-dn.net/?f=Blue%20%3D%2025%20%2A%2016%2F40)
![Blue = 10](https://tex.z-dn.net/?f=Blue%20%3D%2010)
Hence, the expected number of blue marbles is 10

Answer:
Parameter
Step-by-step explanation:
Parameter is a value that summarizes the data/information about a population in its entirety while a statistics summarizes the data/information about a small part/sample of the population.
In this context the underlined 25% represents the parameter because the value is a numerical measurement describing a characteristic of a population which are the national high school students.
You can divide 100 by 4 to find out how many lunches you can buy
or multiply 4 by the number of lunches you have had
100 - that number^=money remaining
