A litter of puppies consists of black puppies and white puppies. A
BartSMP [9]

We want to see if the first selection is dependent on the second selection, we will see that no, the first selection can not depend on a selection that <u>did not happen yet.</u>

So the situation is:

We have a group of puppies, some are black, some are white.

Let's say that there are N puppies in total, n₁ are black, n₂ are white, such that:

n₁ + n₂ = N

Now we have that the first selection, event A, is a black puppy. The probability is just the quotient between the number of black puppies and the total number of puppies:

q = n₁/N

Then now we have:

  • N - 1 puppies in total.
  • n₁ - 1 black puppies
  • n₂ white puppies.

Now for the second selection, event B, the probability of selecting a white puppy is:

P = n₂/(N - 1)

Notice that because there are fewer black puppies than before (because we took one) the denominator decreases, thus, the probability of getting a white puppy increases.

So clearly event B depends on event A.

Now the question is:

Is A dependent on B?

No, A can not depend on event B, because event A happens first. The probability of the first event is always q = n₁/N.

A group of friends spent 1, 0, 2, 3, 4, 3, 6, 1, 0, 1, 2, and 2 hours online last night. What are the 1st and 3rd quartiles for
Ostrovityanka [42]

Arrange the numbers from smallest to largest:

0,0,1,1,1,2,2,3,3,4,6

Split the data in the middle, since there is an odd amount of numbers take an even amount on each side:

0,0,1,1,1,2,2,3,3,4,6

Lower half: 0,0,1,1,1

Higher half: 2,3,3,4,6

1st quartile is the middle value of the lower half: 1

3rd quartile is the middle value of the higher half: 3

A rectangle has a height of 7x^27x 2 7, x, squared and a width of 3x^2+8x+73x 2 +8x+73, x, squared, plus, 8, x, plus, 7. Express
abruzzese [7]

The expression 21x⁴ + 56x³ + 49x² represents the area of the entire rectangle.

<h3>What is the area of the rectangle?</h3>

It is defined as the area occupied by the rectangle in two-dimensional planner geometry.

The area of a rectangle can be calculated using the following formula:

Rectangle area = length x width

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

The area of the rectangle = length x width

= (3x² + 8x + 7)(7x²)

\rm =7x^2\cdot \:3x^2+7x^2\cdot \:8x+7x^2\cdot \:7

= 21x⁴ + 56x³ + 49x²

Thus, the expression 21x⁴ + 56x³ + 49x² represents the area of the entire rectangle.

seems to be the reverse distributive property
normally written as
a(b+c)=ab+ac
we can see the similarity
a(x'+y)=ax+ay
