​a) What percent of all applicants were​ Asian? The percent of all applicants who were Asian is nothing​%. ​(Round to one decima
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%

Rewrite y = x2 +6x+ 10 in graphing (vertex) form by completing the square. State the VERTEX.
tamaranim1 [39]

Answer:

The vertex is (-3,1)

Step-by-step explanation:

Here, we want to write the given function in the vertex form

Mathematically, we have this as;

y = a(x-h)^2 + k

where the vertex is (-h,k)

Thus, we have

Let us divide the coefficient of x by 2, square and add to both sides ; prior to this, we will equate y to 0

Thus, we have it that;

0 = x^2 + 6x + 10

x^2 + 6x + 10 + 9 = 9

x^2 + 6x + 9 = 9-10

x^2 + 6x + 9 = -1

(x + 3)^2 = -1

(x + 3)^2 + 1 = 0

So the vertex here as represented by (-h,k) is;

(-3,1)
