The equation y=6.3x + 67.4 is a linear model for data comparing the ages of boys between ages 2 and 10 years old (x) and their average heights in centimeters (y). what is the average height of a 8 year old boy? rob found that the coefficient of determination between the lengths of essays submitted to a teacher (x) and the score the teacher gave the essay (y) was about 0.661. what can we conclude?

2.56 is the width of the garden

step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
