Consider each of the following relationships. Which school shows the greatest rate of change between male and female students?

ratelena [41]

Answer:

The school C shows the greatest rate of change between male and female students

Step-by-step explanation:

Let

x -----> the number of female students

y ----> the number of male students

we know that

The ratio of male students to female students is

$\frac{y}{x}$

we have

<em>School A</em>

$\frac{y}{x}=\frac{4}{1}=4$

<em>School B</em>

$\frac{y}{x}=\frac{4}{3}=1.33$ ----> the slope of the linear equation

<em>School C</em>

$\frac{y}{x}=\frac{1,260}{280}=4.5$

so

$4.5 > 4 > 1.33$

therefore

The school C shows the greatest rate of change between male and female students
