## Which graph shows that a population is growing over time?

Answer: The first graph because the population increase as time increased.

## What type of graph represents population growth?

When the population size, N, is plotted over time, a J-shaped growth curve is produced. Exponential population growth: When resources are unlimited, populations exhibit exponential growth, resulting in a J-shaped curve. When resources are limited, populations exhibit logistic growth.

## What graph is used for population?

Comparing Line Graphs, Pie Charts, and Bar Graphs Bar graphs are especially useful when comparing quantities. For example, if you are studying the populations of different countries, as in Figure 5, bar graphs can show the relationships between the population sizes of multiple countries.

## Can we draw pie chart in Graph book?

The total value of the pie chart is always 100%. Each portion in the circle shows a fraction or percentage of the total. Pie chart is a circular graph which is used to represent data….Construction of Pie Chart.

Activity | No. of Hours | Measure of central angle |
---|---|---|

Study | 4 | (4/24 × 360)° = 60° |

T. V. | 1 | (1/24 × 360)° = 15° |

Others | 3 | (3/24 × 360)° = 45° |

## How do you turn data into a pie chart?

How to make a pie chart

- Then click to the Insert tab on the Ribbon. In the Charts group, click Insert Pie or Doughnut Chart:
- In the resulting menu, click 2D Pie:
- Once you’ve clicked that, your pie chart will appear!

## What is the formula of pie chart?

The pie diagram formula is given as = ( given data / total value of data ) x 360. Pie Chart Definition: A type of graph in which a circle is divided into sectors that represent a proportion of the whole.

## How do you convert data into a pie chart?

Excel

- In your spreadsheet, select the data to use for your pie chart.
- Click Insert > Insert Pie or Doughnut Chart, and then pick the chart you want.
- Click the chart and then click the icons next to the chart to add finishing touches:

## Does a pie chart have to equal 100?

Not doing the math correctly is a common mistake that makes your pie chart useless. Pie charts are designed to show parts of a whole, so any sum below or above 100% doesn’t represent the entire picture. Finally, when it comes to legends, pie charts don’t generally need one. It’s cleaner to label your data directly.

## How do I make a pie chart with two sets of data in Excel?

Click on the first chart and then hold the Ctrl key as you click on each of the other charts to select them all. Click Format > Group > Group. All pie charts are now combined as one figure. They will move and resize as one image.

## How many degrees does one person represent?

To find out how many degrees represents each adult, you do 360 ÷ 120 = 3 degrees per person.

## How many degrees are in a circle?

360

## How do you convert percentage to degrees?

Explanation: A full circle has 360 degrees, which means that 100% of the circle is 360 degrees. First convert into a decimal. If you multiply 360 by 0.20, you get the degree measure that corresponds to the percentage, which is 72.

## What is the central angle of a pie chart?

A pie chart is made up of a number of sectors and helps to represent different quantities. A protractor is a simple example of a sector with a central angle of 180º. Central angle can also be defined as the angle formed by an arc of the circle at the center of the circle.

## Which sector has the greatest angle?

major sector

## How do you find the angle in a pie chart?

Measure the angle of every segment in the pie chart. Keep the straight 0° line marked on the protractor on one of the straight sides of a segment and read the degrees marked on the protractor on the other straight side of the segment. The answer is the angle of the segment or the slice.

## How do you describe a pie chart in statistics?

A pie chart (or a pie graph) is a circular statistical graphical chart, which is divided into slices in order to explain or illustrate numerical proportions. In a pie chart, centeral angle, area and an arc length of each slice is proportional to the quantity or percentages it represents.

## What can I do if I don’t have a protractor?

However, if you don’t have a protractor handy, you can determine the size of an angle using the basic geometric principles of triangles. You’ll need a scientific calculator to solve the equations. Most smartphones are equipped with them, but you can also download a free app or access a free calculator online.

## How do you find the angle of elevation on a calculator?

Find the angle of elevation of the plane from point A on the ground.

- Step 1 The two sides we know are Opposite (300) and Adjacent (400).
- Step 2 SOHCAHTOA tells us we must use Tangent.
- Step 3 Calculate Opposite/Adjacent = 300/400 = 0.75.
- Step 4 Find the angle from your calculator using tan-1

## How do you find an angle with two sides and one angle?

“SAS” is when we know two sides and the angle between them. use The Law of Cosines to calculate the unknown side, then use The Law of Sines to find the smaller of the other two angles, and then use the three angles add to 180° to find the last angle….In this triangle we know:

- angle A = 49°
- b = 5.
- and c = 7.
