PLEASE HELP ME! Drag the expressions into the boxes to correctly complete the table.

Kamila [148]

The polynomials are:

$x^4+3x^3-5x^2-7x+20$

$x^3-2x^2+x-12$

$x^2+3x^5-6x+12x^3$

Not a polynomial are:

$4\sqrt[3]{x} -\sqrt{x} -20$

$\frac{5}{x^3}-\frac{1}{x^2}+\frac{8}{x}-40$

$x^{-3}-x^{-2}-6x^{-1}+8$

Solution:

Polynomial is an expression with variables and coefficients,

Which involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables

Option 1

$4\sqrt[3]{x} -\sqrt{x} -20$

Polynomial does not include roots

This is not a polynomial equation

Option 2

$x^4+3x^3-5x^2-7x+20$

This is polynomial expression involving addition and subtraction between terms with non-negative integer exponents of variables

Option 3

$\frac{5}{x^3}-\frac{1}{x^2}+\frac{8}{x}-40$

This is not a polynomial. This equations involves negative integer exponents of variables

Option 4

$x^3-2x^2+x-12$

This is a polynomial involving addition and subtraction between terms with non-negative integer exponents of variables

Option 5

$x^{-3}-x^{-2}-6x^{-1}+8$

This is not a polynomial. This equations involves negative integer exponents of variables

Option 6

$x^2+3x^5-6x+12x^3$

This is a polynomial involving addition and subtraction between terms with non-negative integer exponents of variables

It gets cut off but it says ' Write the number marked with an arrow on the number line below as an improper (top-heavy) fraction

Anit [1.1K]

Answer:

1.2

Step-by-step explanation:

it's 1.2 because

the marked parts on the number line represent a fraction of the whole

so in writing this

it will be decimals

and wen the marked lines between 0 and 1 are counted it is 4

so starting each marked line represent 2

so

0.2,0.4,0.6,0.8,1,1.2,1.4,......

so from 1 the next marked part is 1.2

so the answer is 1.2

Suppose that a student who is about to take a multiple choice test has only learned 40% of the material covered by the exam. Thu

Umnica [9.8K]

Answer:

There is a 52% probability that she will get it right.

Step-by-step explanation:

We have these following probabilities:

A 40% probability that the student knows the answer to a question.

A 60% probability that the student does not know the answer to a question.

If the student does not know the answer to a question, a 20% probability of getting the question right guessing.

If we choose a question at random from the exam, what is the probability that she will get it right?

40% probability that she knows the answer

60% that she has to guess, when there is a 20% probability of getting it right. So

$P = 0.4 + 0.6*0.2 = 0.52$

There is a 52% probability that she will get it right.
