The least value is 2 while the maximum value is 9. The scale to be used must accommodate all these values. The scale can thus begin from 0 to 10. Choice A is incorrect since the values 7 and 9 will not be accommodated in the graph.
The y variable represents the number of pages read;
50, 100, 125, 175, 225
The least value is 50 while the maximum value is 225. The scale to be used must accommodate all these values. The scale can thus begin from 0 to 250. Both choices C and D are incorrect since none of the values will be accommodated in the graph.
A^2 + b^2 = c^2....a and b are the legs and c is the hypotenuse 2^2 + b^2 = 4^2 4 + b^2 = 16 b^2 = 16 - 4 b^2 = 12 b = sqrt 12 <=== square root of 12 units
