Bond are the answers.

Answer/Step-by-step explanation:

Given/Solve:

------------------------------------------------------------------------------------------------------------

1. What is the simplified form of - ( x - 4 ) ?

A. - x - 4

B. - x + 4

C. x +4

D. x - 4

- ( x - 4 ) [ - · x = -x ] [ - · -4 = + 4 ]

= -x + 4

------------------------------------------------------------------------------------------------------------

2. Which phrase can you use to represent, m - 4?

A. m less than 4

B. 4 less than m

C. m plus 4

D. 4 less m

------------------------------------------------------------------------------------------------------------

3. Which property is illustrated by the following statement?

3 + x = x + 3

A. Associative Property of Addition

B. Commutative Property of Multiplication

C. Inverse Property of Addition

D. Commutative Property of Addition

Associative property of addition is he sum of numbers remains the same regardless of how the numbers are grouped.

Example:

a + b = b + a

1 + 4 = 4 + 1 .

------------------------------------------------------------------------------------------------------------

4. To which set of real numbers does the following number belong? ( the number is below)

A. rational

B. irrational

C. whole

D. imaginary

The given number, √3 cannot be expressed in the form of p/q. Hence, it irrational.

Suppose that a regression line for some data transformed with logarithms predicts that when x equals 4, log(y) will equal 3.331.

deff fn [24]

Option D

The regression line predicts that at x = 4, y equals 2143

Solution:

Given that when x equals 4, log(y) will equal 3.331

To find: Find y when x equals 4

Since we have given that,

When x = 4,

$\text{ log } y = 3.331$

We need to find the value of 'y' when x = 4

$log_{10}y = 3.331$

Since it is logarithmic function with base 10, Raise to power of 10 on both sides,

$10^{log_{10}y} = 10^{3.331}\\\\\text{10 power log base 10 cancels, we get }\\\\y = 10^{3.331}\\\\y = 2142.89$

On rounding to nearest whole number, we get 2143

Thus Option D is correct

What is the interquartile range of the data? With the numbers 2,3,3,4,5,7,8,8,8,10,10, and 12

harina [27]

Answer:

The interquartile range = 5.5

Step-by-step explanation:

Given the data

2 3 3 4 5 7 8 8 8 10 10 12

As we know that

The interquartile range is the difference between the third and first quartiles.

The first quartile is the median of the bottom half of the numbers.

So, to find the first quartile, we need to place the numbers in value order and find the bottom half.

2 3 3 4 5 7 8 8 8 10 10 12

So, the bottom half is

2 3 3 4 5 7

The median of these numbers is 3.5.

The third quartile is the median of the upper half of the numbers.

So, to find the third quartile, we need to place the numbers in value order and find the upper half.

2 3 3 4 5 7 8 8 8 10 10 12

So, the upper half is

8 8 8 10 10 12

The median of these numbers is 9

so

The third quartile is 9.

The first quartile is 3.5.

The interquartile range is the difference between the third and first quartiles.

The interquartile range = 9 - 3.5 = 5.5

Therefore, the interquartile range = 5.5

Find the factors of f(x) given that x = −3 is a zero.

Rus_ich [418]

$x^3+12x^2+47x+60\\\\=x^3+3x^2 +9x^2+27x+20x+60\\\\=x^2(x+3) + 9x(x+3)+20(x+3)\\\\=(x+3)(x^2+9x+20)\\\\=(x+3)(x^2 + 4x +5x +20)\\\\=(x+3)[x(x+4)+5(x+4)]\\\\=(x+3)(x+4)(x+5)$
