Answer:
10 Values
Step-by-step explanation:
We would use a set of data for illustration
Given the set of numbers:
1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20
Since we have an even number of data, the median is in between 10 and 11.
(1,2,3,4,5,6,7,8,9,10),(11,12,13,14,15,16,17,18,19,20)
Lower Half: (1,2,3,4,5,6,7,8,9,10)
- The median of the lower half is in between 5 and 6. So
is in between 5 and 6.
Upper Half:(11,12,13,14,15,16,17,18,19,20)
- The median of the upper half is in between 15 and 16. So
is in between 15 and 16.
Therefore, we have the [position of the first and third quartiles as:
1,2,3,4,5,,6,7,8,9,10,11,12,13,14,15,
,16,17,18,19,20
There are 10 values in between the first and third quartiles.
Answer:
The distance you are from the base of plateau =
Step-by-step explanation:
Given:
Height of plateau = 70 m
Angle of elevation to the top of plateau = 35°
To find the distance you are from the base of plateau.
We will construct a triangle ABC to model the given situation. The triangle would be a right triangle for which we know an angle and its opposite side. We need to find the adjacent side of the triangle.
We will apply trigonometric ratio to find the adjacent side.
where represents the angle of reference.
Plugging in the values from the triangle.
Multiplying both sides by AC.
Dividing both sides by
∴
The distance you are from the base of plateau =
