b) Do you notice clusters or outliers in the data? Explain your reasoning. (2 points)








c) How would you describe the correlation in the data? Explain your reasoning. (2 points)








d) What are the independent and dependent variables? (2 points)








Step 2: Evaluating trends of data

Because you want to prepare and serve the healthiest food possible, you monitor the fat and calorie content of items on your menu. Some of the menu items are included in the graph below.



a) Your business partner describes this as a high positive correlation. Is your partner correct? Why or why not? (2 points)






b) Using the drawing tools, draw a trend line (line of best fit) on the graph above. (2 points)




c) Judge the closeness of your trend line to the data points. Do you notice a relationship between the data points? (2 points)






d) Is the trend line linear? If so, write a linear equation that represents the trend line. Show your work. (3 points)










Step 3: Making predictions using data

You and your business partner track the number of customers served and the amount of tips collected per day. The data you gathered is displayed in the chart below.

Servers’ Collected Tips
Customers 54 46 34 67 52 22 49 64 55 80 38 42
Tips ($) $92 $80 $76 $121 $109 $43 $87 $114 $99 $174 $88 $91

a) Create a scatterplot displaying the data in the table. Be sure to include a linear trend line. (2 points)







b) Find the equation of the trend line (line of best fit). Show your work. (2 points)



















c) Predict the amount of tips that would be collected if 100 customers were served at the restaurant on a given day. Explain your reasoning. (2 points)


d) Explain how to use the regression calculator to make a reasonable prediction given a data table. (2 points)

Answer:

Chile you didn´t even try like why so many dang questions

Step-by-step explanation:

A .

b . Yes,I do 1,110 is a cluster because it’s a very large number for 52 degrees and 189 is because it’s a very large number for 16 degrees.

c . There is a negative correlation.

D . The dependent variable is sales and independent variable is the temperature.

A. yes my partner is correct because the line goes diagonally upwards.

B. The trend line lies on the points (0,100) and (15,900)D .

C . Yes do see a relationship. This line move one direction up. notice how the dots move up like an escalator.

Volume entering the small intestine: 9,600 mL
Volume entering the large intestine: 560 mL
Volume leaving the large intestine: 140 mL

Required:
a. What percentage of the water entering the small intestine is absorbed by the small intestine?
b. In contrast, what percentage of the water entering the small intestine is absorbed by the Volume leaving the large intestine: 140 mL large intestine?

Answers

Answer and explanation:

The large and small intestine absorb water but the small intestine absorbs more water than the large intestine. Here the small intestine absorbs 9040 ml of water out of 9600ml while the large intestine absorbs the 560ml and 140ml leaves. To calculate percentage that was absorbed by the large intestine(percentage entering the small intestine) and also leaves, we divide the volume that leaves(140ml) by total volume absorbed(560ml) and multiply by 100.

Volume of water entering the small intestine= 9600 ml

Volume of water entering the large intestine= 560 ml

Volume of water leaving the large intestine = 180 ml

Percentage of water entering the small intestine and absorbed by the small intestine= 9600ml - 560 ml= 9040

=9040/9600*100/1= 94.16%

Percentage of water entering the small intestine and absorbed by the volume leaving the large intestine = 560ml-140ml= 140/560*100/1= 25%

Also percentage of water absorbed by large intestine and doesn't leave the large intestine = 420/560*100/1= 75%

a. The percentage of the water entering the small intestine is absorbed by the small intestine is 94.16%

b. The percentage of the water entering the small intestine is absorbed by the Volume leaving the large intestine 140 mL large intestine is 4.375%.

Calculation of the percentage:

(a)

Volume leaving the small intestine should be

= 9600 - 560

= 9040

Now the percentage should be

[tex]= 9040 \div 9600[/tex]

= 94.16%

(b) Water absorbed by large intestine should be = 560 - 140 = 420 ml

Now the percentage should be

[tex]= 420 \div 9600[/tex]

= 4.375%

A.3/5
B.3/2
C.2/3
D.2/5

Answers

The fractions will let her find the x-coordinate for point C is 2/5

How to calculate the midpoint of coordinates

The formula for calculating the midpoint of coordinates is expressed as:

[tex]M(x,y) = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

Substitute the given coordinate into the formulas:

[tex]M(x,y) = (\frac{3(2)+3(6)}{2+3},\frac{2(2)+3(11)}{2+3}) \\M(x,y) = (\frac{24}{5},\frac{37}{5}) \\M(x,y) = (4.8,7.4)[/tex]

From the calculation, we can see that the fractions will let her find the x-coordinate for point C is 2/5

Classify the function as linear or quadratic and identify the quadratic, linear, and constant terms. y= (3x+4)(- 5x - 6)

Answers

Answer:

x1= -4/3 x2= -6/5

Step-by-step explanation:

y= (3x+4)(-5x-6)

now first we replace y with a zero 0

0=(3x+4)(-5x-6)

now we put the 0 to the right

(3x+4)(-5x-6)=0

when the product of factors 0, at least one of the factors is 0 so we do this:

3x+4=0

-5x-6=0

now we solve 3x+4=0 and it leads to:

x=-4/3

after that we do the same for -5x-6=0:

x2=-6/5

Read the story.Racing to RaceCarlo stopped to rest for a minute and tried to catch his breath. Hed been running for so long that he had pains in his side and his legs were beginning to hurt. He hunched over and tried to expand his lungs, but it was like trying to suck air out of a bicycle tire. His body was too exhausted to even allow him to take a deep breath, and he started to wheeze again.Great, he thought, let me just add asthma to my expanding list of ailments. I cant believe that I cant even jog two miles without completely collapsing! He finally gave in to his aching body and laid down on the grass to recuperate. He closed his eyes and tried to imagine himself running on the school track in the 1,600-meter race. He pictured himself running steadily toward the finish line, running effortlessly like a cheetah in the jungle. He was so lost in thought that he didnt even hear Meiya approach.Hey sleepyhead, what are you doing napping on Seans lawn in the middle of the day? Meiya asked playfully.Carlo quickly sat up, breathing normally now and feeling a little embarrassed. I am trying to get in shape to try out for track, but I cant even run two miles, he said dejectedly.Wait, how many months are you out of surgery? Didnt you just finish rehab last week? Meiya asked. You cant expect to run two miles the first day.It had been six months since Carlos surgery and he specifically remembered the doctor telling him he could start running after six months. But he thought about what Meiya had said and realized she had a good point. After his surgery, the doctor did say rehab would be crucial to his recovery but that it would take time for him to gain back full use of his leg. He thought about how a baby had to learn to walk before it could run. He remembered when his nephew was learning to crawl; within days it seemed like he was walking. Running didnt come right away, Carlo remembered. He realized it was the same with his therapy. The maximum he had run in the past month was one mile on the treadmill, so he realized that Meiya was probably right. He would have to work at building up his endurance and set more realistic goals for himself. As he thought about what he had already accomplished, he started to smile and felt like a weight was being lifted off his shoulders. He realized that he had run almost a mile and a half before his body started to protest and if he kept working hard, he could get back to where he was before his accident.Since when did you get so smart, Dr. Meiya? he teased. Do you want to race to the next mailbox?Youre on! she challenged and took off running at full speed.Question 1Part AWhat is a central theme of Racing to Race?A close friend is good medicine.Running a race is not always about winning.Good things always come to those who wait.Recovery from a setback takes time and patience.Question 2Part BWhich statement best shows how the theme identified in Part A is developed in the story?Carlo realizes that he may not be able to compete on the school track team but also discovers that, with time, he will still be able to participate in a sport he loves.Carlo pictures himself winning a big race on the school track team but then he realizes he may have developed asthma.Meiya knows that she is faster than Carlo, so she does her best to encourage him and also lets him win a race between them to boost his spirits.Carlo is discouraged that he has to rest after running a short distance, but Meiya reminds him that he has only just finished rehab.
