<u>Answer:</u>

6x^5-10x^4+12x^3-2x^2


<u>Step-by-step explanation:</u>

We are the following expression and we are to expand it by multiplying the term outside the parenthesis with terms inside it:

[ t e x ] - 2 x ^ 2 ( 3 x ^ 3 - 5 x ^ 2 + 6 x - 1 ) [ / t e x]

Multiplying the term [ t e x ] - 2 x ^ 2 [/ t e x ] with each of the terms inside the brackets to get:

6x^5-10x^4+12x^3-2x^2

Note that the exponents are added when multiplied and since each terms has a different exponent so they cannot be added or subtracted.

Answer:

The correct answer is -6x^5 + 10x^4 - 12x^3 + 2x^2

Step-by-step explanation:

The given expression is -2x^2(3x^3-5x^2+6x-1)

Multiply each term by -2x^2, we get

<u>To evaluate  the expression</u>

-2x^2 *3x^3 -(-2x^2)* 5x^2 + (-2x^2)*6x- (-2x^2)*1

-6x^5 + 10x^4 - 12x^3 + 2x^2

Therefore the correct answer is -6x^5 + 10x^4 - 12x^3 + 2x^2

Rayyan made a $3000 first payment of a car The total cost of a car was $7500 he made 36 equal monthly payments to pay the car in
hammer [34]

Answer:

$125/month

Step-by-step explanation:

<em>equation we got:</em>

7500 = 36x + 3000

<em>subtract</em><em> </em><em>3</em><em>0</em><em>0</em><em>0</em><em> </em><em>from</em><em> </em><em>both</em><em> </em><em>sides</em>

4500 = 36x

<em>divide</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>by</em><em> </em><em>3</em><em>6</em><em> </em><em>to</em><em> </em><em>get</em><em> </em><em>x</em><em> </em><em>by</em><em> </em><em>itself</em>

125 = x

x = 125

<em> </em><em>so</em><em> </em><em>rayyan</em><em> </em><em>paid</em><em> </em><em>$</em><em>1</em><em>2</em><em>5</em><em> </em><em>per</em><em> </em><em>month</em>

torisob [31]

Answer:

The answer to the question is

Point Estimate = 1.5

Margin of error = 0.3

Step-by-step explanation:

A point estimate as opposed to an interval estimate, presented in the question which consist of a range of values, is a specific point or single value to describe a given set of collected data. An example of a point estimate is the mean of a range of values hence the point estimate is given as

(1.2 + 1.8) ÷ 2 which is equal to 1.5

The margin of error is used to describe the required allowance in terms of statistical points or percentage points by which a given set of result could vary from the actual sample. It represents the expected error between the actual population and the survey result

In this case the margin of error from the mean  is

1.5 - 1.2 = 0.3

Margin of error formula is z ×σ/√(n)

where z = z-score

σ = standard deviation

n = number of sampled data

Temka [501]
%change=100(final-initial)/initial

%change=100(7498847290-6672678672)/6672678672

%change=12.38%  (to nearest one-hundredth of a percent)

So the world's population increased by 12.38%.
