The additional cost per month of a sunroof, spoiler and stereo is represented by three consecutive even integers, respectfully.

lesya [120]

Answer:

Step-by-step explanation:

First of all, I think it was "respectively", not "respecfully", =))). A noticeable point.

From the problem, three item's costs are represented by three consecutive even integer.

Thus, we can call cost of spoiler is x, sunroof is x-2, stereo is x + 2. It is conditioned that x is an even number.

Since the sum of the three is 48, we have

(x-2) + x + (x+2) = 48

x+x+x -2 +2 = 48

3x =48

x=16

So the spoiler is 16; thus, the sunroof is 14 and the stereo is 18

Exercises 1–5

Degger [83]

Answer: The estimated value for population mean rating based on these ten sampled ratings is 7.3 .

Step-by-step explanation:

Given : A random sample of size ten produced the following ratings in the computer games rating example in the last lesson:

12, 5, 2, 4, 1, 4, 18, 10, 1, 16.

Let x denotes any value in the above data.

${\sum_{i=1}^{10}x_i}{10}=73$

We know that the sample mean $(\overline{x})$ is the best estimate to the population mean $(\mu)$ .

Sample mean= $\overline{x}=\dfrac{\sum_{i=1}^{n}x_i}{n}$

Here , n= 10

$\overline{x}=\dfrac{\sum_{i=1}^{10}x_i}{10}$

$\overline{x}=\dfrac{73}{10}=7.3$

Therefore , the estimated value for population mean rating based on these ten sampled ratings= 7.3
