all of them
Step-by-step explanation:
Answer: D. range
Step-by-step explanation:
To measure the center of the tendency we use Mean , median or mode depends on the type of data.
But when we discuss about the distance between the initial point and the final point in a data , we use 'range' as term for this.
Range= distance between initial and final point.
here, range = distance between the starting point and the point where water-skiing accident occurs.
Hence, the correct option is D. range
Answer:
2 1/5 ---- 1/10 = 21

Step-by-step explanation:
The length of the ladder is 34.33 feet if the electrician leans an extension ladder against the outside wall of a house so that it reaches an electric box 33 feet up. The ladder makes an angle of 74° with the ground.
<h3>What is a right-angle triangle?</h3>
It is defined as a triangle in which one angle is 90 degrees and the other two angles are acute angles. In a right-angled triangle, the name of the sides are hypotenuse, perpendicular, and base.
We have:
An electrician leans an extension ladder against the outside wall of a
house so that it reaches an electric box 33 feet up. The ladder makes
an angle of 74° with the ground.
The ladder, wall, and ground makes a right angle triangle.
From the sin ratio;
![\rm sin74 = \dfrac{33}{X}](https://tex.z-dn.net/?f=%5Crm%20sin74%20%3D%20%5Cdfrac%7B33%7D%7BX%7D)
Here is X is the length of the ladder.
We know sin74 = 0.961
After putting, we will get:
X = 34.329 ≈ 34.33 feet
Thus, the length of the ladder is 34.33 feet if the electrician leans an extension ladder against the outside wall of a house so that it reaches an electric box 33 feet up. The ladder makes an angle of 74° with the ground.
