Answer:

(x^4y^6+1)(x^8y^{12}-x^4y^6+1)

Step-by-step explanation:

We have been given an expression x^{12}y^{18}+1 and we are asked to factor our given expression.

We will use sum of cubes formula to factor our given expression.

a^3+b^3=(a+b)(a^2-ab+b^2)

Upon using power rule of exponents a^{bc}=(a^b)^{c}, we can write:

x^{12}=(x^4)^3

y^{18}=(y^6)^3

We can write 1 as 1^3 as 1 raised to any power equals 1.

Now we are ready to apply sum of cubes formula.

(x^4y^6)^3+1^3=(x^4y^6+1)((x^4y^6)^2-x^4y^6+1^2)

Upon simplifying right side of our equation we will get,

(x^4y^6)^3+1=(x^4y^6+1)(x^{4*2}y^{6*2}-x^4y^6+1)

(x^4y^6)^3+1=(x^4y^6+1)(x^8y^{12}-x^4y^6+1)

Therefore, after factoring our given expression we get (x^4y^6+1)(x^8y^{12}-x^4y^6+1).

lbvjy [14]
The numbers DO differ by 10 if they are

- 1 and 11
- 2 and 12
- 3 and 13
- 4 and 14
- 5 and 15

Each outcome technically has two ways of occurring, but since we're taking two marbles at a time, that would be the same as saying, for instance, that drawing 1 and 11 is the same as drawing 11 and 1. We only count such an event once.

So the answer is (a) 5.

There are 5 pens in a container on your desk. Among them, 3 will write well but 2 have defective ink cartridges. You will select
Norma-Jean [14]

Answer:

Kindly check explanation

Step-by-step explanation:

Total Number of pens = 5

Number of defective pens = 2

Number of non-defective pens = 3

A.) number of defective pens selected :

X : {0, 1, 2}

It is possible that no defective pen will be selected ; 1 defective will be chosen or both pens are defective.

2.)

Defective as Success (since selecting a defective pen is the point of interest.

3.)

Since selection is done without replacement

Probability of success per selection is different for each selection ;

Number of defective = 2

Number of observations = 5

P(success on first selection) = 2/5

P(success on second selection) = 1/4

Hence, X is not well approximated by a binomial random variable.

4.) if selection is done with replacement ; then then the probability of success per selection will be the Same for each selection made. Hence, X will be well approximated by a binomial Random variable.

5.) If sampling is done without replacement, then the the hypergeometric function will be a more effective approximation.
