The number of data set (n) is equal to 40

Data Given;

  • sum of the data set = 800
  • mean = 20
  • number of data set = ?

<h3>What is Mean</h3>

This is the average of a particular data set.

To solve this problem, we would apply the formula of calculating mean.

x = \frac{sum}{n}

substitute the values and solve for the number of data set

20 = \frac{800}{n}\\ n = \frac{800}{20}\\ n = 40

From the calculations above, the number of data set here is 40.

What is the height of this isosceles triangle?
erastova [34]

Answer:

height ≈ 11.9 units

Step-by-step explanation:

Construct a perpendicular bisector from the vertex to the base, thus splitting the triangle into 2 right triangles.

Using the sine ratio in one of these right triangles, then

sin48° = \frac{opposite}{hypotenuse} ( the opposite is the height h )

sin48° = \frac{h}{16} ( multiply both sides by 16 )

16 × sin48° = h , thus

h ≈ 11.9 ( to the nearest tenth )
