Answer:

Step-by-step explanation:

5(x-3y)+2(4x+y)-(x+y)

5x-15y+8x+2y-x-y

5x+8x-x-15y+2y-y

13x-x-13y-y

12x-14y
explanation:
add 5x and 8x and you get 13x−15y+2y−x−y
then subtract x from 13 x and you get 12x-15y+2y-y
then you add -15y and 2y and you get 12x-13y-y
then you subtract y from -13y and you get 12x-14y (answer).

Amy has 4 pound of ground pork to make meatballs she uses 3/8 pound per meatball to make 9 meatballs.how many 1/8 pound meatball
Studentka2010 [4]

Amy can make 29 meatballs from the remaining beef.

What are mathematics operations?

  • An operation is a function in mathematics that converts zero or more input values (also known as "operands" or "arguments") to a well-defined output value.
  • The operation's arity is determined by the number of operands.
  • Binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive inverse and multiplicative inverse, are the most commonly studied operations.
  • A zero-arity operation, also known as a nullary operation, is a constant.
  • The mixed product is an example of an arity 3 operation, also known as a ternary operation.

Amy has 4 pounds of ground beef to make meatballs and he uses 3/8 pound per meatball to make 9 meatballs

We have to subtract 3/8 from 4

= 4 - 3/8

= 29/8

There are 29/8 pounds of ground beef left

Therefore the number of 1/8 pound meatball that can be produced from 29/8 pounds of ground beef can be calculated as follows;

= 29/8 ÷ 1/8

= 29

Hence Amy can make 29 meatballs

g Suppose I will flip a fair coin until it lands Heads for the first time, and you will receive $2 if the game lasts for 1 round
Anuta_ua [19.1K]

Answer:

Step-by-step explanation:

The main idea is that I would like to pay less than what I'm expecting to win, so in that way, I get a profit out of playing this game. Let X be the number of tosses until I get a Heads. By definition, this is a geometric random variable with parameter p = 1/2.

Let Y the amount I received for playing. So, we want to calculate the expected value of Y.

We can calculate it as follows

E[Y] = 2 P(X=1)+ 4 P(X=2)+ 8 P(X =3)  + \dots  = \sum_{n=1}^infty 2^n P(X=n)

Since X is a geometric random variable, we have that P(X=n) = (\frac{1}{2})^{n-1}\frac{1}{2}

Then,

E[Y] = \sum_{n=1}^\infty 2^{n} (\frac{1}{2})^{n-1} \frac{1}{2} = \sum_{n=1}^\infty 2^{n-1} \cdot \frac{1}{2^{n-1}} = \sum_{n=1}^\infty 1 = \infty

So, we expect to have an infinite amount. Given this, we can pay as much as we want to play the game.

What is the value of (3/10)3
Elenna [48]

Answer:

\frac{9}{10}

Step-by-step explanation:

In this question, one is asked to multiply a fraction by a whole number, first model the question.

\frac{3}{10}(3)

In a situation like this, one multiplies the whole number by the numerator (number) over the fraction.

\frac{3*3}{10}

Simplify,

\frac{9}{10}

A common error that people make is that they will multiply both the numerator and denominator by the whole number, this is the same as multiplying the answer by (1), thus it is incorrect.
