The other possibilities include that she chooses at least one book that is not a mystery; this means the complement is not choosing all mysteries.

<h3>What is the probability?</h3>

Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

P(E) = Number of favorable outcomes / total number of outcomes

Mariah is randomly choosing three books to read from the following: 5 mysteries, 7 biographies, and 8 science fiction novels.

The complement of an event is the remaining possibilities.

Our event is Mariah choosing 3 mysteries.

The other possibilities include that she chooses at least one book that is not a mystery; this means the complement is not choosing all mysteries.

F(x)=x2+8x+6. What is the value of f(4)?
dezoksy [38]

When it says f(4) that means x=4

So you then just fill in all the x’s with 4’s and solve as normal

The steps to convert 18 over 8 to a decimal are shown below: Division is shown with divisor 8 and quotient 2.35 and dividend 18.
natka813 [3]

Answer:

Step 2

18 over 8 to a decimal is 2.25

Step-by-step explanation:

Step 1, 20, subtract 16 labeled as

Step 2, 40 labeled as

Step 3, subtract 40, and 0 labeled as Step 4.

Divisor = 8

Divided = 18

Quotient = 2.25

2.25

8 √18

- 16

2 0

- 16

4 0

- 40

0

The first error is at step 2

18 over 8 to a decimal is 2.25

What was the equation of the graph below before it was shifted to the right 1.5 units?
Ira Lisetskai [31]

Answer:

 B is correct.

{tex]G(x)=x^3-x[/tex]

Step-by-step explanation:

We are given a graph of cubic polynomial after shift 1.5 unit right.

Equation of given graph is

G(x)=(x-1.5)^3-(x-1.5)

For right and left shift, change in x value or horizontal translation.

If we shift "a" unit left then change in x

x\rightarrow (x+a)

If we shift "a" unit right then change in x

x\rightarrow (x-a)

Here, we need to shift 1.5 unit left to get original function.

G(x)=(x-1.5)^3-(x-1.5)

Shift 1.5 unit left

F(x)=(x-1.5+1.5)^3-(x-1.5+1.5)

F(x)=x^3-x

Hence, B is correct function.
