13 ESSA É A RESPOSTA CORRETA DA SUA PERGUNTA.
Answer:
a) p=0.2
b) probability of passing is 0.01696
.
c) The expected value of correct questions is 1.2
Step-by-step explanation:
a) Since each question has 5 options, all of them equally likely, and only one correct answer, then the probability of having a correct answer is 1/5 = 0.2.
b) Let X be the number of correct answers. We will model this situation by considering X as a binomial random variable with a success probability of p=0.2 and having n=6 samples. We have the following for k=0,1,2,3,4,5,6
.
Recall that
In this case, the student passes if X is at least four correct questions, then

c)The expected value of a binomial random variable with parameters n and p is
. IN our case, n=6 and p =0.2. Then the expected value of correct answers is 
Y+4=2/3(x+3)
(-3,-4)(3,0)
1.find the slope
m=y2-y1/x2-x1
m=0-(-4)/3-(-3)
m=4/6
m=2/3
y-(-4)=2/3(x-(-3))
y+4=2/3(x+3) point-slope form
Answer:
True
Step-by-step explanation:
anything over 9 that is not 9 is a repeating decimal
