Nata [24]3 years ago
4 0

Answer:

- 4096

Step-by-step explanation:

There is a common ratio between consecutive terms of the sequence.

r = - 4 ÷ 2 = 8 ÷ - 4 = - 2

This indicates the sequence is geometric with n th term

a_{n} = a r^{n-1}

where a is the first term and r the common ratio

Here a = 2 and r = - 2 , thus

a_{12} = 2 × (-2)^{11} = 2 × - 2048 = - 4096

(4x^5-15x^3-10x^2)-(2x^5-5x^3-2x^2)

So, the first thing we will do is add like terms. But before that, lets get rid of both parenthesis. We'll just get rid of the first pair, and for the second pair, we will multiple everything in the second parenthesis by -1

4x^5-15x^3-10x^2-2x^5+5x^3+2x^2

Now, we will add like terms.

2x^5-10x^3-8x^2

Now, there's a common factor that all of these terms share; it's 2x^2. 2x^5 can be divided by 2, as well as -10x^3 and -8x^2 (these are the coefficients, number found in front of the variable.) So, we'll distribute 2

2x^2(x^3-5x-4)    (we take the 2x^2 out by dividing all terms by 2x^2)

So, our answer would be

2x^2

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..
