Answer:
4a^2-19ab-5b^2
Step-by-step explanation:
What you do is the FOIL process.
F=First. The first thing that you do is times 4a and a together to get 4a^2.
O=Outer. You multiply the outer numbers 4a and -5b together to get -20ab.
I=Inner. You multiply the inner numbers b and a together to get ab.
L=Last. You multiply the last numbers b and -5b together to get -5b^2.
Put it all together to get 4a^2-19ab-5b^2 as your answer.
Circle graphs are used to display the relationship between variables using a complete circle
The angle measures of the sections are 180 degrees, 72 degrees, 72 degrees and 36 degrees, respectively.
The count of the animals are given as:
- Squirrel = 25
- Rabbit = 10
- Deer = 10
- Raccoon = 5
The total count of animals is:


The angle measure of each section is then calculated using:

So, we have:

Simplify the numerator

Divide


Simplify the numerator

Divide


Simplify the numerator

Divide

Lastly, we have:

Simplify the numerator

Divide

Hence, the angle measures of the sections are 180 degrees, 72 degrees, 72 degrees and 36 degrees, respectively.

Answer:
The answer is "Option 2".
Step-by-step explanation:
Please find the complete question in the attached file.
When there is a mean value k in a set of data. Otherwise, we will assert with certainty that at least one of the values is k. They can't say anything at all about the maximum or even the minimum using knowledge only. Nevertheless, we know that certain numbers cannot be over and that all numbers cannot be below than mean. Mean also no value throughout the data set must be equal.
