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

Is this a linear function?
Artemon [7]

Answer:

No

Step-by-step explanation:

No

Because a linear function is the form as

f(x)=ax+b

the highest exponent is one

and the graph is a line in the case of

p(x)=3x^2-4

is a parabola, not a line
