Answer:

1. Range: take the difference between the highest and lowest values in a set of numbers. In this case it's 2 and 45.

2. Mean: Mean is the average of the numbers. This is pretty easy just add up all the numbers you see and divide by how many there are.

3. Median: The median is basically taking your numbers and organizing then. Then you go through and cross off every number until you get to the one number in the middle. If you have 1 answer, then that's your answer..But if you have two numbers in the middle add them up and divide by 2.

4. Mode: Mode is the value that appears most often. In this case it would be 16 and 3.

Larger (upper) and lower quartile: if you have a calculator this might help a lot when finding what you are looking for. But anyways this is for TI-84 plus calculator. Go to stat, press 1. edit, then enter your numbers, press start again, move right to calc, and press 1 again. Scroll down and press calculate, then scroll all the way down and find Q1 (lower) and Q3 (upper)

Step-by-step explanation:

Range: 45-2 = ? (I will let you solve this part yourself)

Mean: 5 + 16+ 45 + 12 + 11 + 9+ 16 + 21 + 2 + 3 + 8 + 3 + 7 + 2 + 5 = ? ÷ 15 (I believe that how many numbers there are, I can't tell)

Median: 2, 3, 3, 5, 7, 8, 9, 11, 12, 16, 16, 45, in this case you will be left with two numbers. So once you cross off the numbers and get to the middle remember to add together the middle numbers and divide by 2.

Mode: 16 and 3

Larger and lower quartile: Q1: 3 and Q3: 16

(if this isn't it try minx: 2 and maxx: 45)

I think they should help explain what you are doing and get you started. Sorry I couldn't be much more help. :)

Answer: Their equations have different y-intercept but the same slope

Step-by-step explanation:

Since, the slope of the line passes through the points (2002,p) and (2011,q) is,

$m_1 = \frac{q-p}{2011-2002} = \frac{q-p}{9}$

Similarly, the slope of the line asses through the points (2,p) and (11,q) is,

$m_2 = \frac{q-p}{11-2} = \frac{q-p}{9}$

Since, $m_1 = m_2$

Hence, both line have the same slope.

Now, the equation of the line one having slope $m_1$ and passes through the point (2002,p) is,

$y - p = \frac{q-p}{9}(x-2002)$

Put x = 0 in the above equation,

We get, $y = \frac{2000(p-q)}{9}+p$

The y-intercept of the line one is $(0, \frac{2000(p-q)}{9}+p)$

Also, the equation of second line having slope $m_2$ and passes through the point (2,p)

$y-p=\frac{q-p}{9}(x-2)$

Put x = 0 in the above equation,

We get, $y = \frac{2(p-q)}{9}+p$

The y-intercept of the line one is $(0, \frac{2(p-q)}{9}+p)$

Thus, both line have the different y-intercepts.

⇒ Third option is correct.

The revenue of a company that makes backpacks is given by the formula R = 34.S0x, where x represents the number of backpacks sol

alexgriva [62]

Answer:

Revenue = 1380

Step-by-step explanation:

Given:

Revenue means the sales or turnover of a company when it sells its products. In other words, it is nothing but the income of a company on selling the products.

Here, the company is selling backpacks. So, revenue is the amount earned by the company on selling 'x' backpacks. The linear model to represent the same is given below.

The revenue received from selling 'x' backpacks is given as:

$R=34.50x$

Number of backpacks sold (x) = 40

Now, in order to find the revenue received on selling 40 backpacks, we need to plug in 40 for 'x' in the equation above and solve for the revenue, 'R'.

On plugging 40 for 'x', we get:

$R=34.50\times 40\\\\R=1380$
