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

School A

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

School B

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

School C

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

$4.5 > 4 > 1.33$

therefore

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

A right triangle has side 10 and hypotenuse 26. Use the Pythagorean Theorem

alekssr [168]

Answer:

Step-by-step explanation:

The Pythagorean Theorem states that $a^{2} +b^{2} =c^{2}$ where a and b are the legs in a right triangle and c is the hypotenuse. Therefore, just substitute the values a = 10 and c = 26 into the equation to get b = 24

Hope this helps :)
