In a math class with 27 students, a test was given the same day that an assignment was due. There were 17 students who passed th

timama [110]

Answer:

The probability that a student who completed the homework failed the test is 0.211.

Step-by-step explanation:

The probability of an event E is the ratio of the favorable number of outcomes to the total number of outcomes.

$P(E)=\frac{n(E)}{N}$

The conditional probability of an event A given that another event B has already occurred is:

$P(A|B)=\frac{P(A\cap B)}{P(B)}$

Denote the events as follows:

P = a student passes the test

F = a student fails the test

X = a student completes the assignment

Y = a student does not completes the assignment

From the information provided the summary table is as follows:

P F Total

X 15 4 19

Y 2 6 8

Total 17 10 27

Compute the probability that a student completed the assignment and failed the test as follows:

$P(X\cap F)=\frac{n (X\cap F)}{N}=\frac{4}{27}$

Compute the probability that a student completed the assignment as follows:

$P(X)=\farc{19}{27}$

Compute the probability that a student failing the test given that the student completed the assignment as follows:

$P(F|X)=\frac{P(X\cap F)}{P(X)}=\frac{4/27}{19/27}=\frac{4}{19}=0.21053\approx 0.211$

Thus, the probability that a student who completed the homework failed the test is 0.211.

Find the midpoint of the line segment whose endpoints are (-2, 5) and (4, -9).

daser333 [38]

Solving for the midpoint can be done by looking for the average of each of the given x-coordinates and y-coordinates. The 2 obtained averages are the new x-coordinate and y-coordinate. This shown below:

Midpoint = ( (-2 + 4)/2 , (5 + -9)/2 )
Midpoint = (1,-2)

Therefore, the new midpoint is (1,-2)
