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

denis-greek [22]

Answer:

The greatest rate of change is for <u>school A</u> as it has the greatest ratio of 2.5

Step-by-step explanation:

School A:

Ratio of male to female students, $m_A=5:2=\frac{5}{2}=2.5$

School B:

Male students are related to female students by equation:

$y=2x$

Where, $x$ means number of female students and $y$ means number of male students.

Therefore, the ratio of male to female students is, $m_B=\frac{y}{x}=2$

School C:

Ratio of male to female students is, $m_C=\frac{\textrm{Number of male students}}{\textrm{Number of female students}}=\frac{200}{120}=1.67$

Now, rate of change of male to female students is directly proportional to the ratio of the two.

Hence, the greater the ratio, the greater the rate of change.

So, the greatest rate of change is for school A as it has the greatest ratio of 2.5

Please help me find the area of each shaded segment and round the answer to the nearest tenth :)

Keith_Richards [23]

Hi there!

In order to solve, we need to use the formula for the area of a circle, and the angle given to find the area of the sector. Then, subtract the area of the triangle to find the area of the segment. We would use the equation : A = x/360 (pi * r^2) - 1/2(b * h). We need to plug in 90 for the angle measurement, 8 for the radius, and 8 for both the base and height.

WORK:
A = 90/360 (pi * 64) - 1/2(64)
A = 1/4(64pi) - 32
A = 16pi - 32 = ~ 18.3ft^2

Hope this helps!! :)
