Answer:

1) 1/10

2) 1/2

3) 1/5

Step-by-step explanation:

1)

1 favorable outcome and 10 total outcomes.

$P(3) = \frac{1}{10}$

2)

5 favorable outcomes and 10 total outcomes

$P(even) = \frac{5}{10} = \frac{1}{2}$

3)

2 favorable outcomes and 10 total outcomes

$P(multiples\ of\ 5) = \frac{2}{10} = \frac{1}{5}$

What is the factored form of x^12y^18+1

Black_prince [1.1K]

Answer: The required factored form of the given expression is

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

Step-by-step explanation: We are given to find the factored form of the following algebraic expression:

$E=x^{12}y^{18}+1.$

We will be using the following formula:

$a^3+b^3=(a+b)(a^2+ab+b^2).$

Now, we have

$E\\\\=x^{12}y^{18}+1\\\\=(x^4y^6)^3+1^3\\\\=(x^4y^6+1)\{(x^4y^6)^2-x^4y^6\times1+1^2\}\\\\=(x^4y^6+1)(x^8y^{12}-x^4y^6+1).$

Thus, the required factored form of the given expression is

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

Answer:

HL

Step-by-step explanation:

the shared hypotenuse and congruent legs of the triangle means it is congruent by HL

you might think that SSA is also doable because there is a right angle in both triangles but it is not

a way to remember this is that "there are no donkeys in geometry" because SSA backwards is another word for donkey
