Armans age : x
Aregs age: y

X = 5y
(15 - 12) = y. They said narek is 12 years older than areg so you deduct 12 years from nareks age which is 15.

So therefore y = 3. So Areg is 3 years old.

Since we know that y = 3
X = 5(3)
X = 15

So therefore Arman is 15 years and Areg is 3 years.

A random variable is a function that assigns numerical values to the outcomes of a random experiment. True or false?
Alex787 [66]

Answer:

FALSE

Step-by-step explanation:

A random variable is a variable whose outcome depends on random criteria, such as a lottery game in which any number can be drawn randomly. That way, a randomized experiment will have random results that are not predetermined. For example, if the lottery has 80 numbers, the random variable function can achieve any result, which will depend on random criteria such as the luck of the player.

IgorC [24]

Factoring is a common mathematical process used to break down the factors, or numbers, that multiply together to form another number. Some numbers have multiple factors.

<u>Explanation:</u>

Factoring polynomials involves breaking up a polynomial into simpler terms (the factors) such that when the terms are multiplied together they equal the original polynomial. Factoring helps solve complex equations so they are easier to work with. Factoring polynomials includes: Finding the greatest common factor.

Factoring (called "Factorizing" in the UK) is the process of finding the factors: Factoring: Finding what to multiply together to get an expression. It is like "splitting" an expression into a multiplication of simpler expressions.
