Answer:

Rational numbers are numbers that can be written as the fraction of two integers. To multiply rational numbers together, you multiply the tops and bottoms separately to get your answer. If you can simplify your problem before you multiply, your problem will be easier to solve!

Step-by-step explanation:

we know that

<u>Counting backwards</u> is when the numbers are count in reverse sequence

Is also know as 1 less

In this problem the sequence of counting backwards from 5 is equal to

4,3,2,1,0

Evaluate the following expressions giving the functions g(x)= -4x+3 <br> g(10) is the expression

Artemon [7]

Answer:

g(10) = -37

Step-by-step explanation:

g(x)= -4x+3

g(1) means evaluate when x=10

g(10) = -4*10 +3

g(10) = -4*10 +3

g(10) = -40+3

g(10) = -37

Item 1 A bag contains 7 blue cards, 4 green cards, 6 red cards, and 8 yellow cards. You randomly choose a card. a. How many poss

egoroff_w [7]

Answer:

4 possible outcomes

Step-by-step explanation:

we know that

The probability of an event is the ratio of the size of the event space to the size of the sample space.

The size of the sample space is the total number of possible outcomes

The event space is the number of outcomes in the event you are interested in.

so

Let

x------> size of the event space

y-----> size of the sample space

so

$P=\frac{x}{y}$

In this problem

<em>The probability of choose a blue card is </em>

$x=7$

$y=7+4+6+8=25$

substitute

$P=\frac{7}{25}$

<em>The probability of choose a green card is </em>

$x=4$

$y=7+4+6+8=25$

substitute

$P=\frac{4}{25}$

<em>The probability of choose a red card is </em>

$x=6$

$y=7+4+6+8=25$

substitute

$P=\frac{6}{25}$

<em>The probability of choose a yellow card is </em>

$x=8$

$y=7+4+6+8=25$

substitute

$P=\frac{8}{25}$

The sum of the probabilities of the 4 possible outcomes is equal to

$\frac{7}{25}+\frac{4}{25}+\frac{6}{25}+\frac{8}{25}=\frac{25}{25}$ ----> represent the 100%
