Question

Meghan measures the heights and arm spans of the girls on her basketball team. She plots the data and makes a scatterplot comparing heights and arm spans, in inches. Meghan finds that the trend line that best fits her results has the equation y=x+2 . if a girl on her team is 64 inches tall, What should Meggan expect her span to be?

Answer 1

EXPLANATION

Let's see the facts:

The equation is given by the following expression y= x + 2

---> 64 inches tall

As we can see in the graph of arm span versus height, and with the given data the arm span should be:

arm span = y = 64 + 2 = 66 inches

So, the answer is 66 inches. [OPTION C]
