A scatterplot is produced to compare the size of a lake to the number of fish that are in it. There are 15 data points, each rep
resenting a different lake. The points are widely dispersed on the scatterplot with no pattern of grouping. Interpret what the results of the scatterplot tell you about the relationship between the two variables.
Since there is no cluster formed in the scatterplot, the two variables are not related. Therefore, based on the data shown in the scatterplot, the number of fish in a lake is not dependent on the size of the lake.
Consider one pyramid Side length of base = 1.5cm and its height is 1 cm Slant height of one of the lateral faces = sqrt(1^2 + 0.75^2) = 1.25 cm Area of one of the triangular faces = 0.5 * 1.5* 1.25 = 0.9375 cm^2
There are 8 of these so the required surface area = 8 * 0.9375 = 7.5 cm^2 Answer
The best correct answer is option E. If two or more polygons are congruent, then rigid transformations can be used to map one polygon onto the other. <span>Two figures are said to be congruent when they have the same shape and
size or if one object is a mirror image of the other object.</span>
