Just by looking at the table, the equation looks like it is y = -x - 2. This is a linear equation, since the highest power of x is x (rather than x^2, x^3, etc). The answer is A.

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

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.

Answer:

x = 30°, y = 90°

Step-by-step explanation:

$(y + x) + (y - x) = 180 \\ 2y = 180 \\ y = 90 \\$

$2x + y + x = 180 \\ 3x + 90 = 180 \\ 3x = 90 \\ x = 30$
