Correct Answer is : Graph 2

Peak | Elevation (in ft) |

1 | 6641 |

2 | 6660 |

3 | 6641 |

4 | 6680 |

Step: 1

Start at the origin on a scatter plot.

Step: 2

Move 1 unit to the right on the horizontal axis.

[To represent Peak 1.]

Step: 3

Move 6,641 units up from the horizontal axis and plot a point.

[The height of the peak 1 is 6,641 ft]

Step: 4

From the origin move 2 units to the right on the horizontal axis.

[To represent Peak 2.]

Step: 5

Move 6,660 units up from the horizontal axis and plot a point.

[The height of Peak 2 is 6,660 ft.]

Step: 6

From the origin move 3 units to the right on the horizontal axis.

[To represent Peak 3.]

Step: 7

Move 6,641 units up from the horizontal axis and plot a point.

[The height of Peak 3 is 6,641 ft.]

Step: 8

From the origin move 4 units to the right on the horizontal axis.

[To represent the Peak 4.]

Step: 9

Move 6,680 units up from the horizontal axis and plot a point.

[The height of Peak 4 is 6,680 ft.]

Step: 10

Plot 4 is the scatter plot that represents the data given in the table.

Correct Answer is : Plot 4

Hours worked ( | Weekly pay ( |

10 | 50 |

12 | 55 |

14 | 55 |

15 | 60 |

16 | 73 |

18 | 70 |

20 | 75 |

22 | 87 |

23 | 90 |

Step: 1

Construct a scatter plot for the data.

Step: 2

From the scatter diagram, we can say that as the hours worked increases the weekly pay also increases.

Step: 3

So, the relationship is a positive relationship.

Step: 4

Therefore, Graph 1 is the correct answer since it matches the graph plotted.

Correct Answer is : Graph 1, positive relationship

Number of rooms ( | Percentage of number of houses ( |

1 | 2.2 |

2 | 4.8 |

3 | 9.7 |

4 | 16.0 |

5 | 20.9 |

6 | 18.5 |

7 | 12.1 |

8 | 8.1 |

9 | 7.7 |

Step: 1

Plot the scatter diagram for the data.

Step: 2

From the scatter diagram, we can say that the graph does not follow any trend.

Step: 3

So, there is no relationship.

Step: 4

Therefore, Graph 2 is the correct answer since it matches the graph plotted.

Correct Answer is : Graph 2, no relationship

Car Type | Weight (pounds) | miles per gallon |

A | 2750 | 29 |

B | 3125 | 23 |

C | 2100 | 33 |

D | 4082 | 18 |

E | 2690 | 20 |

F | 3640 | 21 |

G | 4380 | 14 |

H | 2241 | 25 |

I | 2895 | 31 |

J | 3659 | 17 |

Pick the appropriate scatter plot for the data.

Step: 1

The values in the table match with Graph 3.

Correct Answer is : Graph 3

Step: 1

There exists a positive relationship between the weight and seeds in papaya if the weight increases with the number of seeds.

Step: 2

Only Graph 2 shows this relation. So, Graph 2 is the correct answer.

Correct Answer is : Graph 2

Grades | Boys | Girls |

8^{th} | 80 | 25 |

9^{th} | 60 | 30 |

10^{th} | 40 | 35 |

11^{th} | 30 | 45 |

12^{th} | 20 | 65 |

Step: 1

The height of each point represent the number of students of a particular gender in a particular grade.

Step: 2

The yellow colored points in the scatter plots represent the number of boys and the blue colored points represent the number of girls in each grade.

Step: 3

Observe the scatter plots for the heights of the points to match with the values in the table.

Step: 4

It can be observed that the scatter plot given in Plot 3 exactly matches the values given in the table.

Step: 5

So, Plot 3 is the appropriate scatter plot graph for the data.

Correct Answer is : Plot 3

Age (in years) | Weight (in pounds) |

2 | 20 |

3 | 20 |

4 | 28 |

5 | 35 |

6 | 35 |

Step: 1

In the scatter plots, the age of the child is taken along the x-axis and his weight is taken along y-axis.

Step: 2

Each point indicates the weight of the child at the particular age.

Step: 3

Observe the graphs to match the heights of the points with the values given in the table.

Step: 4

It is observed that the points in Figure 3 exactly match the values in the table.

Step: 5

So, Figure 3 is the appropriate representation of the values in the table.

Correct Answer is : Figure 3
