An automotive manufacturer wants to know the proportion of new car buyers who prefer foreign cars over domestic. Step 1 of 2: Su

AVprozaik [17]

Answer:

0.249 is the required proportion.

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 822

Number of people who preferred foreign cars over domestic, x = 205

We have to find the proportion of new car buyers who prefer foreign cars.

Formula:

$\hat{p} = \dfrac{x}{n}$

Putting values, we get,

$\hat{p} = \dfrac{205}{822}\\\\\hat{p} = 0.249$

Thus, 0.249 is the proportion of the new car buyers who preferred foreign over domestic cars..

(-4,5) and (4,0) find the distance between each pair of points

aleksklad [387]

Answer:

9.4339 units

Step-by-step explanation:

Here we are given with two coordinates and asked to determine the distance between them.

Here we are going to use the distance formula, which is given as under

$D=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}$

Where

$(x_1,y_1) = (-4,5)$

$(x_2,y_2) = (4,0)$

Replacing these values in the distance formula

$D =\sqrt{(-4-4))^2+(5-0)^2}$

$D =\sqrt{(-8)^2+(5)^2}$

$D =\sqrt{64+25}$

$D =\sqrt{89}$

$D= 9.4339$

Hence the distance is 9.4339 units

Answers:

5) product is $35ax^2 - 42axy + 7y^2$

6) product is $-a^6b^2 - 8a^5b - 5a^4$

7) product is $12x^5y + 6x^4y^2 + 21x^3y^3$

8) product is $3x^3y^2 - 6x^3y + 3x^5y - 3x^4y$

9) product is $x^{3n} + 7x^{n+1} - 3x^n$

=============================================

Explanation:

For each of these questions, you'll multiply the term outside by each term inside the parenthesis. I'm using the distributive property.

In problem 5, we multiply the outer 7a by the following terms inside like so

$7a(5x^2-2xy+y^2-4xy)\\\\7a(5x^2-6xy+y^2)\\\\7a(5x^2)+7a(-6xy)+7a(y^2)\\\\35ax^2-42axy+7ay^2\\\\$

The other problems will have similar steps.

--------

A useful rule to keep in mind is that $a^b*a^c = a^{b+c}$

For example, $x^2*x^3 = x^{2+3} = x^5$
