The coordinates below are the three vertices of a rectangle. Identify the fourth coordinate and the area of the rectangle.
Ne4ueva [31]
Answer:
C

Explanation:

C is the most reasonable choice since the rectangle has to have 4 sides with all vertices having a right angle.

Then, after the point (2,2) has been plotted. You can then find the area which is 24 units squared.

A and B are two events. Let P(A) = 0.3, P(B) = 0.9, and P(Aand B) = 0.24. Which statement is true?
gavmur [86]

Answer:

blue one (c), not independent because P(A|B) ≠ P(A)

Step-by-step explanation:

Two events are independent of each other if you can mulitply them to get their intersection

To find the conditonal probability of two independent events you can use the following idea/formula

P(A|B)= (P(A)*P(B))/P(B) which simplifies to P(A) (so the probability of A given B when A and B are independent of each other is just the probability of A)

Now with the numbers we're given let's find P(A|B)

.24/.9= .26666666666667

Because this is not equal to .3 (or P(A)) the answer must be the blue one

What is the distance between the points (–8, –2) and (–7, –2)?
tensa zangetsu [6.8K]
You subtract 7 from 8 and you get 1.
You do not subtract 2 from 2 because they are the same. You have to subtract coordinates that are not the same.
Another way to figure this out would be to plot the points on the coordinate plane and count how many spaces is in between.  

The answer is A.1<span />

Eight identical slips of paper, each containing one number from one to eight, inclusive, are mixed up inside a bag. Subset A of
DochEvi [55]

Answer:  The correct option is (C) A = {1, 2, 3, 4, 5, 7, 8}.

Step-by-step explanation: Given that eight identical slips of paper, each containing one number from one to eight, inclusive, are mixed up inside a bag.

The sample space, S will be

S = {1, 2, 3, 4, 5, 6, 7, 8}.

Subset A of the sample space represents the complement of the event in which the number 6 is drawn from the bag.

Let, 'B' represents the event in which the number 6 is drawn from the bag.

So, B = {6}.

Since 'A' is the complement of 'B', so the set 'A' will contain those element of the sample space 'S' that are not in the set 'B'.

Therefore,

A = B' = {1, 2, 3, 4, 5, 7, 8}

⇒ A = {1, 2, 3, 4, 5, 7, 8}.

Thus, (C) is the correct option.
