Question

the angle of a sector of an outcome in a pie chart is 45°. the ratio of frequency of this outcome to the total frequency is ​

Answer 1

Step-by-step explanation:

The angle of a sector of an outcome in a pie chart = 45°

The ratio of frequency = 45 / 360 ( as the pie chart measures 360° ) = 1 : 8

Answer 2

Answer:

The ratio of the frequency of this outcome to the total frequency is ​1:8

Step-by-step explanation:

Given:

We have been given that the angle of a sector of an outcome in a pie chart is equal to $45$°.

To find:

We have to find out the ratio of the frequency of this outcome to the total frequency.

Solution:

The total frequency would be taken as $360$° because the circle makes a full angle of $360$°.

The ratio will be written as:

$\frac{45}{360} = \frac{1}{8}$

The ratio of the frequency of this outcome to the total frequency is ​1:8

Additional information:

• A circular statistical graphic representation that is divided into various slices and helps to illustrate numerical proportions in a much easier way is known as a pie chart.
• The length of an arc of each slice is proportional to the quantity represented by the commodity in the pie chart.
• The use of pie charts is pretty common when it comes to worldwide business industries and mass media.
• Pie charts are used in these fields because the data can be interpreted much more easily when represented in a diagrammatical fashion.

Final Answer:

Hence, the ratio of the frequency of this outcome to the total frequency is ​1:8
