Use the graph to approximate each answer. At what time on January 20 was low tide at Maalaea? What was the height then?

So if we look at the chart way confined the average of before the feet change by adding up all the blue numbers. And since there's 10 members divided by 10 so that average is 42.7, and we can also do the same for the after by adding all those up and dividing by 10. Mhm. So the question did ask about the average daily milk yield of the cow, so it looks like the feed increased it. But we're also asked to use a box and whisker plot to support her answer. So let's just do it at the before numbers. And let's put them in order from the smallest to the largest. So have to 30 nines. Ah, 40. Another 40 2 40 twos. 43 44 and then 47 and 51. Mhm. Okay, so the median we'll go in five right there. So the meeting is 40 to the lower court. Ellis 40. The upper quartile is 44 the lowest 39 in the high 51. Now let's do the same with E after numbers, and then we'll make that's getting there. So our lowest is a 39 And then next we have 44. 46 2 40 nines. 50 51. What's another 50 than a 51? Okay, then a 52 and a 53. So what kind of five? For the median. So the meeting is 49.5. The lower court owes 46 opera quartile 51. Well, it was 39 the highest 53. Yeah. So we're gonna make a box and whisker plot for each of these using one number line. Mm. To go from said 35 2 55. Mhm. It's fixes. Okay, so the for the blue, the low 39 in the high 51 median 42 the work Wartelle 40 upper quartile 44. And then we have for the after 39 by a 53. 49.5 and then 51 and then 46. Let's do this. Okay. So you can see the median has definitely changed. Highlight that pink from there to there, and you could see that 50% of the data the middle 50% is a lot higher in the after effects to even though the lows air the same and the highest aren't that different? You could see like the middle section has definitely shifted for improvement.

Okay. So I'll use this graph. Okay. To find at what time on January 20 was a low tide at Kahului Louis. Okay. And what was the height so of January 20? The low tide was at Around six p.m. And The heart was around zero two. Okay. Okay.

Over here In this question, we've been provided the equations for whole milk and the reduced so ws for whole milk and artist for reduced May. The question is asking us to find a point ready parabolas I intake intersecting each other. So for that, see the parabolas will invade intersect Only at that point where the musical toe asked that means the consumption off Coldwell will become equal to the conventional reduced me. So for that, what we'll do just quit Budisa questions. But W is equal to add So you will be getting zero point 32 p square minus seven point 69 p less 43.3 equal to zero. Okay, solve this equation. So this quadratic equation using the quadratic formula, you'll get the X values put The X values in one of the equations will get the corresponding why value and that represent those two points at crystal parabolas when intersect each other. So see as I say, just use the quadratic formula. What is the quadratic formula was two point karadic formalistic will do say he is goingto minus b less minus and the Ruto be square minus four. Is he upon the way they would these values over here in the protracted formula. That's really very simple. Uh, we've already discussed this sample of paint before in a previous questions also, so we'll be giving the values off key, as if one value will be nine point 005 On the other, value will be 15 point 0 to 6. I think something around. Yes, As I said, just put These are used in any off the equation on Cal critic Corresponding value by. So let's say I just put the value in a w. So what? They what? I'll get valuable. So for 9.5 corresponding value off five will be 74.355 35 months Mickey on for when you put physical to 15.26 we get why is equal to 55.5 to 3. We fight 23 So the required point that representative uh, you can see part the W is equal to one over. The calculus are intersecting at 9.5 Uh huh, coma. Same people, 0.351 This is one ordered pick on the other one will be 15 point 0 to 6. Goma 5. 55 points. Fight 23 Okay. Also, the question was asking you to explain what does this point to present? So this will represent just the party and see just the instinct way. The consumption off Foreman will become equal to the consumption of the reduced.

In problem 71. The information is given that we can interpret the point on the graph 0 124 to be the number of farms in 1997. So in this case, are variable X is the number of years after 1997 and are variable. Why is the number of farms? So when we look at part A and we, we we begin to start writing an equation. We know that our be value is 124 leaving us on Lee to find the n value or the slope. In order to write or linear equation, we can use the 0.0, 124 and 1 117 to assault for the slope. Why? To 117 minus y 1 124 over acts 21 minus zero leaves us with a quantity of negative 7/1. So our slope is negative. Seven. Now we can write the linear equation Negative seven ax plus 124 equals. Why? So here we are, with our linear model for this equation Next in part B, we want to explain the meaning of the slope. Well, the slope in this case we have identified as the Value negative seven. In this case, we're talking about the number of funds so we can interpret the slope to be number of farms we eliminated each year. Bastar 1997. In other words, there are seven less farms Fiji approximately because this is just a model, so that's important to keep in mind. Finally, in part C, we want Teoh. Figure out the number of farms in 2004. Well, 2004 is seven years after 1997. So we're looking at an X value of seven. We can substitute this value into our equation. Negative seven times seven plus 124 equals Why, which will give us the number of farms in the year 2004 Negative 49 plus 124 will equal why and thus there should be approximately 75 farms in the year 2004. So we have our solution 75 farms and there you have a B and C of problem number 71
