Step-by-step explanation:
3(x-6)^4+11=15
3(x-6)^4=15-11
(x-6)^4=4/3
x-6 = +![\sqrt[4]{4/3}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B4%2F3%7D)

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
