Attached the solution. It is important to know the 30-60-90 and 45-45-90 special right triangles.
Mean absolute deviation (MAD) of the data set indicates the average distance of all elements from mean of the data set.
MAD of the data represented by dot plot in the picture will be Option A.
Elements in the given dot plot are,
3, 4, 5, 5, 5, 5, 5, 5, 6, 7
Steps to be followed for the mean absolute deviation of this data set.
- Find the mean of the data set
- Find the absolute distance of each element from the mean
- Find the average distance of all the elements which will be MAD of the data set.
Step - 1 :
Mean of the data set =
=
=
(As shown on the dot plot)
Step - 2 :
Absolute distance of each element from the mean of the data set,
3 - 5 = |-2| = 2
4 - 5 = |-1| = 1
5 - 5 = 0
5 - 5 = 0
5 - 5 = 0
5 - 5 = 0
5 - 5 = 0
5 - 5 = 0
6 - 5 = 1
7 - 5 = 2
Step - 3 :
Average of the absolute distance =
=
= 0.6
Therefore, Option A will be the correct option.

Answer:
Triangular pyramids find the volume by using the equation V=(1/3)AH
Where A = area of base (hint: cut in half and treat like a right triangle knowing the hypotenuse and 1 side)
And H = height

Answer:
That's the symbol for pi
Step-by-step explanation:
0.5 x 10^5 = 50,000
0.05 x 10^5 = 5,000
5. When you multiply by a power of 10, the decimal point moves (4) places to the (right) for every power of 10. In the expression 8.0 x 10^4, the power of 10 is (4). To multiply 8.0 x 10^4, the decimal point needs to move (4) places to the (right). The product of 8.0 x 10^4 is (80,000). Jayla is incorrect.
