ANSWER

P(X=4 or X=1)=0.2

EXPLANATION

From the table, the probability that X=4 is P(X=4)=0.15

and the table, the probability that X=1 is P(X=1)=0.05

We want to find P(X=4 or X=1)

Recall that

P(X=4 or X=1)=P(X=4)+P(X=1)

We substitute the given probability values to obtain:

P(X=4 or X=1)=0.15+0.05

P(X=4 or X=1)=0.2

Which ordered pairs are solutions to the inequality 2x+y>−4?

alexgriva [62]

Answer:

The ordered pairs are (5,-12), (-1,-1).

Step-by-step explanation:

Given : Inequality $2x+y>-4$

To find : Which ordered pairs are solutions to the inequality ?

Solution :

We put the given options the point which satisfied the equation is the solution.

Inequality $2x+y>-4$

1) (5,-12)

$2(5)+(-12)>-4$

$10-12>-4$

$-2>-4$

It is true.

2) (-1,-1)

$2(-1)+(-1)>-4$

$-2-1>-4$

$-3>-4$

It is true.

3) (-3,0)

$2(-3)+(0)>-4$

$-6+0>-4$

$-6>-4$

It is false.

4) (4,-12)

$2(4)+(-12)>-4$

$8-12>-4$

$-4>-4$

It is false.

Therefore, The ordered pairs are (5,-12), (-1,-1).

Answer:

$\displaystyle \frac{8}{18} = \frac{4}{9}\ ,\ \displaystyle \frac{12}{27} = \frac{4}{9}$

Step-by-step explanation:

<u>Equivalent Fractions</u>

Two fractions are equivalent if they represent the same rational number, regardless of their expression. For example, the fraction 2/5 is equivalent to 10/25 since they both represent the number 0.4

To find if a given fraction is equivalent to another given fraction, we can simplify or amplify it until an equivalence is found or not. We can also simply perform the division and compare the results.

We must find out if the four choices are equivalent to the fraction 4/9. Let's start with the first one

$\displaystyle \frac{20}{36} =\frac{5}{9}$
