Likurg_2 [28]

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%

Dara invests $800 at 12.5% per
VARVARA [1.3K]

Answer:

By the end of the first year Dara will have $903.125 in his account.

Step-by-step explanation:

Since this a compounded interest formula, it means that the amount invested grows exponentially overtime. In order to calculate the total of money over a period of time we must use the following formula:

M(t) = M(0)*(1 + r/n)^(n*t)

Where M(t) is the amount of money in "t" years, M(0) is the amount invested, r is the anual interest rate, n is the compound period over a year and t is the time elapsed in years.

In this problem the amount is compounded half-yearly, this means that for every year that passes the money is compounded twice, therefore n is equal to 2. Applying the data from the problem to the formula, we have:

M(1) = 800*(1 + 0.125/2)^(2*1)

M(1) = 800*(1.0625)^(2)

M(1) = 800*(1.0625)^(2) =903.125

By the end of the first year Dara will have $903.125 in his account.
