NARA [144]

Answer:

percentage of professional professor are 75

Step-by-step explanation:

Given data

academic professors A = 60%

professors  tenured P = 70%

professors at Paracelsus University = 90%

to find out

what percent of the professional professors

solution

we know 90% of the professors are academic professors or tenured or both so we can say percent of academic professors = 60 + 70 - 90 = 40

because here

total = A + P - both

90 = 60 + 70 - both

both = 40

so professors  tenured will be here 70 - 40 = 30

so

percentage of professional professor are = 30 / 40 × 100

percentage of professional professor are 75

Based on the information below, what are the values of x and y of the solution to the system of equations used to create the inf
Alborosie

Answer:

Option D) is correct

That is x=2 , y=-5

Step-by-step explanation:

Given that the |A|=\left| \begin{array}{cc}4&-6\\ 8&-2\end{array}\right|, \left|A_x\right|=\left|\begin{array}{cc}38&-6\\ 28&-2\end{array}\right|, \left|A_y\right|=\left|\begin{array}{cc}4&38\\ 8&26\end{array}\right|

To find their determinants

|A|=\left| \begin{array}{cc}4&-6\\ 8&-2\end{array}\right|

=-8+48

=40

Therefore |A|=40

|A_x|=\left|\begin{array}{cc}38&-6\\ 28&-2\end{array}\right|

=-76+156

=80

Therefore |A_x|=80

|A_y|=\left|\begin{array}{cc}4&38\\ 8&26\end{array}\right|

=104-304

=-200

Therefore |A_y|=-200

To find the values of x and y:

x=\frac{|A_x|}{|A|}\ \textrm{and}\ y=\frac{|A_y|}{|A|}

x=\frac{80}{40} and y=\frac{-200}{40}

x=2 and y=-5

Option D) is correct

That is x=2 , y=-5
