B) 6c + 12 CD = 192

Adding the equations we get

0 + 6 CD = 72

$144+81=c^2$
$225=c^2$
$15=c$

Therefore the perimeter is 12 + 9 + 15 = 36 in. (B)

Answer:

Follows are the solution to this question:

Step-by-step explanation:

The missing data is defined in the attached file please find it.

Given:

Admission Status

$\left\begin{array}{ccccc}Ethnography &Acceptable \ Approval &Waitlisted & Turned \ Away & Total\\\\ Hispanic/ Black & 51 &206&143 & 400 \\Asia &57&289&100&446\\White& 62&222&145&429\\ Total & 170& 717& 388& 1275\end{array}\right \\\\\\$

In point A:

The overall percent of applicants, which is Asia:

$= \frac{446}{1275} \\\\ = 0.3498039 \approx 34.98 \%$

In point B:

The overall percent of the students, who admitted to Asia:

$P(accepted\ Asian) = P( \frac{Placcepted \ Asian}{Asian})$

$= \frac{\frac{57}{1275}}{\frac{446}{1275}} \\\\= \frac{57}{1275} \times \frac{1275}{446} \\\\= \frac{57}{446} \\\\= 0.1278027\approx 12.78 \%$

In point C:

The Asian percentage approved:

$P(Asian/accepted) =\frac{P(accepted, Asian)}{P(accepted)}\\$

$=\frac{\frac{57}{1275}}{\frac{170}{1275}} \\\\= \frac{57}{1275} \times \frac{1275}{170} \\\\= \frac{57}{170} \\\\= 0.3352941\approx 33.52%$

In point D:

The number of all students admitted:

$=\frac{170}{1275}\\\\= 0.13333 \\\\= 13.33%$
