Answer:
area = 26 cm²
Step-by-step explanation:
The formula for the area of a triangle is: area = ![\frac{1}{2}bh](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7Dbh)
Where b = the length of the base and h = height.
In the given problem h = 4 cm and b = 13 cm, so we can plug these values into the equation and multiply:
area =
.
Answer:
the median is 5
hope this helps
have a good day :)
Step-by-step explanation:
It is not a <u>probability distribution</u>, as the sum of the probabilities is more than 1, thus, the correct option is No, considering that:
c) Since the sum of the probabilities is not equal to 1.
-----------------------------------------
For the sequence
representing a probability distribution, it is needed that:
- All probabilities are between 0 and 1, that is, for all values of x,
. - The sum of all probabilities is 1, that is:
![\sum_{i = 1}^n P(x_i) = 1](https://tex.z-dn.net/?f=%5Csum_%7Bi%20%3D%201%7D%5En%20P%28x_i%29%20%3D%201)
In this problem, the sum of the probabilities is:
![\sum_{i = 1}^n P(x_i) = 0.39 + 0.69 + 0.12 = 1.20](https://tex.z-dn.net/?f=%5Csum_%7Bi%20%3D%201%7D%5En%20P%28x_i%29%20%3D%200.39%20%2B%200.69%20%2B%200.12%20%3D%201.20)
<u>Sum is not 1,</u> thus it is not a probability distribution, and the correct option is:
c) Since the sum of the probabilities is not equal to 1.
