A triangle is 180 degrees, so if you do 180-34 is should equal 146, so b + c = 146°
Using it's concept, it is found that the median number of monthly absences is of 13.
The <em>median </em>of a data-set is the <u>value that separates the bottom 50% of the data-set from the upper 50%</u>.
The first step is ordering the data-set, hence:
2, 10, 12, 14, 16, 18
In this problem, the cardinality is of 6, which is a even number.
- Hence, the median is the <u>mean of the 6/2 = 3rd and 4th elements</u>.
Then:
![\frac{12 + 14}{2} = 13](https://tex.z-dn.net/?f=%5Cfrac%7B12%20%2B%2014%7D%7B2%7D%20%3D%2013)
The median number of monthly absences is of 13.

For this case we have a function of the form:
![y = f (x)](https://tex.z-dn.net/?f=y%20%3D%20f%20%28x%29)
Where:
![f (x) = - 4x ^ 2-3x + 2](https://tex.z-dn.net/?f=f%20%28x%29%20%3D%20-%204x%20%5E%202-3x%20%2B%202)
We must find the value of the function when
, that is,
. So:
![g (-2) = - 4 (-2) ^ 2-3 (-2) +2](https://tex.z-dn.net/?f=g%20%28-2%29%20%3D%20-%204%20%28-2%29%20%5E%202-3%20%28-2%29%20%2B2)
We have to:
![- * - = +\\- * + = -](https://tex.z-dn.net/?f=-%20%2A%20-%20%3D%20%2B%5C%5C-%20%2A%20%2B%20%3D%20-)
So:
![g (-2) = - 4 (4) + 6 + 2\\g (-2) = - 16 + 8](https://tex.z-dn.net/?f=g%20%28-2%29%20%3D%20-%204%20%284%29%20%2B%206%20%2B%202%5C%5Cg%20%28-2%29%20%3D%20-%2016%20%2B%208)
Different signs are subtracted and the major sign is placed.
![g (-2) = - 8](https://tex.z-dn.net/?f=g%20%28-2%29%20%3D%20-%208)
Answer:
![g (-2) = - 8](https://tex.z-dn.net/?f=g%20%28-2%29%20%3D%20-%208)
The larger integer has to be at least 16.
Answer:
A
Step-by-step explanation:
A piece wise function involves two or more functions over specific intervals. The equations of the two lines are the following y=-2x+1 and y=-x+2. The line y=-x+2 continues to the right but has an open circle at the end so this point is not included. This means the interval is a greater than than sign but is not equal to. A is the answer.
