Anna007 [38]

Answer:

a) 83%

b) 0.892

Step-by-step explanation:

percentage that attends class on friday = 74%

percentage that pass because they attend class on friday = 88%

percentage that pass but did not go to school on friday = 20%

a) percentage of students expected to pass the course

= (74% x 88%) +(88% x 20%)

= 0.6512 + 0.176

= 0.8272

= 83%

b) If a person passes the course, what is the probability that he/she attended classes on Fridays

= 74% divided by 83%

= 0.892

The answer is: [A]: " -53 " .
_______________________________________________________
Explanation:
_______________________________________________________
Given:

" Let f(x) = -2x − 7 and g(x) = -4x + 3. Find (f o g)(-5) " ;
_______________________________________________
First, find g(-5) . g(x) = -4x + 3.

g(-5) = -4*(-5) + 3 = 20 + 3 = 23 ;
_______________________________________________
Now find f (g(-5) to get the answer; that is f(23);
_______________________________________________
Find f(23). f(x) = -2x − 7 .

f(23) = (-2*23) − 7 = -46 − 7 = -53 ; which is "Answer choice: [A]" .
