Question

An electronics store placed an ad in the newspaper showing five flat-screen TVs for sale. The ad says, "Our flat-screen TVs average $\$ 695 . "$ The prices of the flat- screen TVs are $\$ 1200, \$ 999, \$ 1499, \$ 695, \$ 695, \$ 1100, \$ 1300,$ and $\$ 695 .$
As a consumer, which measure would you want to see advertised? Explain.

the number 18 is still using the information from number 16. So we have the mean TV price was $1047 the median price was $1049 the mod TV price was 6 95 And so the question for 18 is thinking on a different perspective. So if I&#x27;m a buyer and the price in the paper is saying, 6 95 is the average price, but that&#x27;s not the case. In fact, if you look at the mean or the median, the they&#x27;re pretty similar. They&#x27;re very closer to their only, you know, a little less than $2 off of each other. So, um, I would suggest either one would be acceptable because they&#x27;re both representing the center of the data. So that we&#x27;re trying to figure out is what&#x27;s gonna be better like if I&#x27;m going in and I&#x27;m buying? I&#x27;m going to see that 6 95 I&#x27;m gonna go in and then I&#x27;m going to see that the majority of the TV&#x27;s are not 6 95 They are more closer towards $1000 and I&#x27;m gonna be a little upset, probably that I was misled as a buyer, so I could see why. As a as an advertiser or business owner, you&#x27;re going to try and promote the cheaper price. But really, you&#x27;re going to want to know what&#x27;s gonna be the average price. And if the average price is the 1047 nuts right down the middle, that&#x27;s an acceptable answer. And even the median is still somewhat acceptable. So I would say with this reasoning that I just stick the median or I think would be acceptable as your answer.

So 17 Number 17 is what we&#x27;re on now. And so, um, it is asking us to use the answers we got in number 16 to be able to answer this question. So this TV store is trying to promote a price, and they&#x27;re saying the $695 is there. Is there selling typical selling point for these TVs? And so we&#x27;re asked, like so, which one did they use? And since the mode was the 6 95 that means the advertisers or the store is easing them based off of their ad.

so the next couple problems are going to be talking about TVs and starts with number 16. But we are asked to calculate the mean. The meeting in the mode of a stores set of different TV says that they have in their prices. And so we&#x27;re going to add up all the numbers. As you can see, we have them already listed. So I&#x27;m just going to write ad, uh oh numbers just to save some room and then remember, when we&#x27;re finding the mean or the average of the same thing. Or there&#x27;s we also call X Bar a czar symbol. When we do that, we&#x27;re dividing by the number that was in that list originally. So we&#x27;ve got 12345678 different sets of TV prices. And so we&#x27;re gonna go ahead and add up the 6 95 plus the 6 95 plus the 8 95 plus 9 +99999 plus 1100 plus 1200 plus 1300 plus 14 99. And I get 8000 383 evident about eight. And remember, we&#x27;re dealing with money, so you&#x27;re gonna want to make sure you around your money to the nearest two sets. So two decimal places. So the average cost of the TVs is $1047 round 2 88 sets. That&#x27;s the average. So then our task is to look at our list and find the media so that you look at your list and order from smallest to largest, largest to smallest, simply matter, and you&#x27;re going to start on the outside so the 6 95 of the 14 and nine and work your way into the middle. So ah, 6 95 of the 1300 work away in again 8 95 100 and then you&#x27;ll notice that it goes rectangle between the 99 999 and 1100 so that whenever that happened, you take those two numbers and you&#x27;re basically finding the average of those two numbers. So I&#x27;m gonna take 909 plus 1100 divided by two, and that&#x27;s going to get us 999 plus 1100 is 2000 90 nine. Divided by two is gonna put us at 1000. Okay, make that look a little bit nicer. 1000 49 dollars and 50 cents. And remember to fund a calculator. Add that zero to make it look nice because we&#x27;re talking about money. And then the last thing we need doesn&#x27;t involve really any math. It&#x27;s just looking at your list and determining which numbers, if any, occur the most. So 695 if you figure, um, shows up the most, so $695 is our mode.

and this question, or give it where this question were given S, which is a function of Pierre s is the sales of a product. P is the price of the product and a is the amount spent on advertising. Now I highlighted a because A is the about thousands of dollars. So in first part for a, uh, does f&#x27;s f sub p positive or well, let&#x27;s think about this. If the price of the product goes up logically, we know that they&#x27;re seals. Go down, right? Because people, generally speaking, don&#x27;t want to spend a lot of money when the problem Sorry when the price goes up. So peace for price on the price goes up. Sales now Part B were asked to explain the meaning of F sub. A comma 12 equals 100. Well, basically, what that means is that if the product, if the price of the product is a doors and 12,000 dollars has had have been spent on advertising, well, why did we say 12,000 will remember? And now a is in thousands of the price of a product is $8 well, 1000 had been spent on advertising. It&#x27;s 1000 more dollars, for an additional $1000 have been spent on advertising. Well, then the sales would go up by 150 uh, units.

If someone could sell 2400 minus P televisions at p dollars per television, the price that will maximise will be found by multiplying the price times the number that you&#x27;re going to sell. And that&#x27;s equal to negative keys. Where plus 2400 p the, um maximum will happen at the Vertex. The Vertex is found by negative be over to a comma. C minus. B squared over four A. In this case, a is negative. One B is 2400 and see is zero. So we have negative B over to a comma, C minus. B squared over for a or night, 2400 divided by a negative two, which is 1200 and then zero minus 24 hundreds. Weird over negative for just 1,440,000. So what price will maximize the revenue? This would be the price. $1200. Her television

So for this example, we&#x27;re gonna find the straight line depreciation equation for the TV and a Craigslist ad, and the ad tells us that&#x27;s a three year old, 46 inch TV that really has nothing to do with it. Three years old is important, nor it also has surround sound and picture in picture, but we don&#x27;t really care about that. It was purchased for 717 $51,750 new and they&#x27;re asking $800 so we know our initial value. That&#x27;s $1750 that&#x27;s gonna be RB and are sold. Intercept equation. Wife was an explosive. We are starting amount. What we don&#x27;t know is there slope. So to find Slope, we can use the changing Why over change in X equation and in this case, that would be changing money over changing time. And so the TV went from a value of 17 58 100 which is a change of $950 and it&#x27;s also negative, and that happened in a three year period so we can go ahead and change that into a unit rate. And so that&#x27;s about negative $316.67 per year. So now I know my slope and my y intercept of 17 50. So I can write a straight line equation, which would be, why equals negative. 316.67 x plus 17 50 Now, if you kept yourself as a fraction, you might just have this as negative 9 50 over.
