Question

11 Points given (I dont have any left :( )

The first four points in this table have been plotted on the scatter graph. Species 1 2 1 2 1 Length (cm) 6.8 7.8 5.8 6.6 6.3 Wingspan (cm) 9.9 8.8 8.6 8.0 9.2 a) Which of the points A-D shows where the last point should be plotted? b) What shape should the last point be? Length and wingspan of two butterfly species 10- Wingspan (cm) 9- co 5 O O Ax xB CD + 6 Length (cm) 7 co Key Species 1 ■ Species 2​

Answer 1

C, circle

Explanation:

You want to find the point on the graph that has coordinates (6.3, 9.2) and the symbol for Species 1.

Graph

The horizontal axis is labeled "Length (cm)", so the desired point will have a horizontal coordinate of 6.3. The minor grid lines have a spacing of (1 cm)/5 = 0.2 cm. This means the desired point will be located 0.3/0.2 = 1.5 minor grid lines to the right of the one marked 6 cm. Points A and C are in that location.

The vertical axis is labeled "Wingspan (cm)", so the desired point will have a vertical coordinate of 9.2. The minor grid lines have a spacing of (1 cm)/5 = 0.2 cm, so the desired point will be 0.2/0.2 = 1 minor grid line above the one marked 9 cm. Point C is in that location.

(a) Point

The last point will be plotted at location C.

(b) Symbol

The last point in the table has a "Species" of "1", so will be plotted with a dotted circle.
