The relative frequency approach to probability uses long term relative frequencies, often based on past data.

Mathematics
1 answer:
xenn [34]3 years ago
4 0

Answer:

True

Step-by-step explanation:

Relative frequency is the ratio of the occurrence of a singular event and the total number of outcomes. This is a tool that is often used after you collect data. You can compare a single part of the data to the total amount of data collected.

For example, if a particular machine produces 50,000 widgets one at a time, and 5,000 of those widgets are faulty, the probability of that machine producing a faulty widget is approximately 5,000 out of 50,000, or 0.10.

If the length of each side of the right triangle shown on the grid is measured in cm, find the area of the triangle.
Rus_ich [418]

The area of the given triangle is 25 square cm.

Step-by-step explanation:

Step 1:

First, we plot the coordinates of the triangle.

The right bottom end of the triangle is at (15, 5).

The bottom left end of the triangle is at (10, 5).

The top left end of the triangle is (10, 5).

The area of a triangle is given by half the product of its base length and the height of the triangle.

Step 2:

The area of a triangle= \frac{1}{2} (base)(height).

The base is the distance between the bottom two points. The base length= 15 -10 = 5 cm.

The height is the distance between the two left points. The height= 15 - 5 = 10 cm.

The area of the triangle = \frac{1}{2} (5)(10) = 25.

The area of the given triangle is 25 square cm.
