I ONLY NEED HELP WITH 2 AND 6 TEH REST ARE FOR INFO


Josue and Sara both walk dogs during the week. They each walk 10 dogs in the morning and 10 other dogs in the afternoon. Select one of the groups to see how much the dogs in each group weigh. The heavier dogs usually have more energy and want to take longer walks than the smaller dogs.

Josue's dogs:
Morning:
26, 21, 15, 35, 38, 16, 13, 28, 30, 25
Afternoon:
15, 12, 9, 7, 44, 23, 55, 10, 37, 35 Sara's dogs:
Morning:
39, 21, 12, 27, 23, 19, 19, 31, 36, 25
Afternoon:
15, 51, 8, 16, 43, 34, 27, 11, 8, 39
1. Which dog-walker did you select? Circle one.

Josue

Comparing the Morning and Afternoon Groups
2. Create frequency tables to represent the morning and afternoon dogs as two sets of data. Group the weights into classes that range 10 pounds. (4 points: 2 points for appropriate intervals, 2 points for correctly portraying data)







3. What is the median of the morning (AM) group? What is the median of the afternoon (PM) group? (2 points: 1 point for each answer)

Am group median: 25.5 Pm group median: 19




4. What is the first quartile (Q1) of the morning (AM) group? What is the first quartile (Q1) of the afternoon (PM) group? (2 points: 1 point for each answer)


Am group first Quartile = 16 Pm group first Quartile = 10



5. What is the third quartile (Q3) of the morning (AM) group? What is the third quartile (Q3) of the afternoon (PM) group? (2 points: 1 point for each answer)
Am group third Quartile = 30 Pm group third Quartile = 37





6. Create a comparative box plot for the morning and afternoon dogs, and label each with its five-number summary. (6 points: 3 points for the correct form of plot, 3 points for appropriate labels)

7. What is the interquartile range (IQR) of the morning (AM) group? What is the interquartile range (IQR) of the afternoon (PM) group? (2 points: 1 point for each answer)

Am group Interquartile Range = 14 Pm group Interquartile Range = 27





8. The average weights of the dogs are the same for the morning and afternoon groups. But based on your comparative box plot and the IQRs of the two groups, which group of dogs do you think would be easier to walk as one group? Why? (2 points: 1 point for answer, 1 point for justification)


Am group because its Interquartile gruop is smaller than the Pm group

Answer: Doctor A: 751.6   Doctor B: 755.2   Doctor B has an average of 3.6 more patients wearing corrective lenses than Doctor A.

Step-by-step explanation:

To find the mean for corrective lenses, add up all of the numbers and divide by the number of data points.

Doctor A's mean:

Add up the data points: 745+726+769+765+756+742+747+748+770+738 = 7516. Count the number of data points to get 10. Divide 7516 by 10. 7516/10 = 751.6.

Doctor B's mean:

Add up the data points: 763+736+735+759+748+756+765+761+768+761 = 7552. Divide by 10. 7552/10 = 755.2

Difference:

755.2-751.6 = 3.6

Answer:

Doctor A: 751.6 Doctor B: 755.2 Doctor B has an average of 3.6 more patients wearing corrective lenses than Doctor A.

[tex]-\displaystyle\frac{1}{2} :1\frac{3}{4}[/tex]

First , convert the mixed number (the fraction we are dividing by in the given maths problem) into an improper fraction .

Multiply the whole part (1) times the denominator (4) and add the numerator . The result is the numerator of our fraction , and the denominator stays the same .

So now our maths problem looks as follows :

[tex]-\displaystyle\frac{1}{2} :\frac{7}{4}[/tex]

Now turn the fraction you are dividing by over :

[tex]-\displaystyle\frac{1}{2} *\frac{4}{7}[/tex]

Now multiply the numerator of the first fraction times the numerator of the second fraction :

4

Perform the same operation with the denominators :

-4/14

So the result is :

[tex]-\displaystyle\frac{4}{14}[/tex]

Since the above fraction is not in it's simplest form , we divide the top and bottom by 2 (a common factor of both 4 and 14) :

Answer:

-2

Step-by-step explanation:

and don't care about handwriting

Answer:

14 - 9x + 12 + x

This is an expression (not an equation), therefore it can't be solved.

Factor the expression

Collect like terms:  

⇒ 14 + 12 - 9x + x

Combine like terms:  

⇒ -8x + 26

Find the highest common factor of 26 and 8

Therefore, the highest common factor is 2

Factor out -2 from -8x + 26:

⇒ -2(4x + 13)

Alternatively, factor out 2 from 26 - 8x:

⇒ 2(13 - 4x)

Answer:

0.201

Step-by-step explanation:

Answer:

0.0201

Step-by-step explanation:

Okay so first you ignore the decimal places. That way your equation is set up like this

.67

x .03

Multiply as normal and add the 2 products together as such

201

+ 000

Then, you need to move the decimal depending on the amount of decimal places. In this case there are 4, so you would move the decimal over 4 times.

Answer:

The mean for Doctor A's set of contacts is 107.7 and the mean for Doctor B's set of contacts is 118.6. I'll let you do the rest :)

A little reminder about mean: mean is when you add up all the numbers then divide by how many numbers there are, hoped this helped (*^▽^*)

Answer: Doctor A's set of contacts is 107.7 and the Mean for Doctor B's set of contacts is 118.6. 

Step-By-Step Explanation:  Upon further examination of the data sets, it is interesting to note that the age groups represented in the first and second sets differ significantly. The first set had a higher percentage of individuals aged 40 and above, while the second set had a higher percentage of individuals aged 20-30. This information could provide valuable insights into age-related trends in eye care practices and could potentially lead to the development of more targeted treatment options for different age groups.

Furthermore, it is important to consider other factors that may influence the wearing of contact lenses, such as geographical location and occupation. It would be interesting to analyze data sets from different regions and industries to identify any patterns or trends that may emerge.

In conclusion, the analysis of data sets related to eye care practices can provide valuable insights into different aspects of our lives. It is essential to continue exploring and analyzing such information to make informed decisions and improve the quality of eye care for those who wear contact lenses.

Answer:

52

Step-by-step explanation:

since HI and JK are parallel lines, angle K is congruent to angle I.

Now that you know that, we just need to know that a triangle's angles always add up to 180 degrees which means that x is 180-62-66

Answer:

Angle x = 52

Step-by-step explanation:

Angle HIA = Angle JKI = 63

This is because both angles are corresponding angles HI//JK

Angle x = 180 - 66 - 62

             = 52

Answer: x = 2

Step-by-step explanation:

[tex]$$Solve for $x$ :$$\frac{x+4}{3}=\frac{x+6}{4}$$Multiply both sides by 12 :$$\frac{12(x+4)}{3}=\frac{12(x+6)}{4}$$$$\begin{aligned}&\frac{12}{3}=\frac{3 \times 4}{3}=4 \\&4(x+4)=\frac{12(x+6)}{4}\end{aligned}$$$$\begin{aligned}&\frac{12}{4}=\frac{4 \times 3}{4}=3 \\&4(x+4)=3(x+6)\end{aligned}[/tex]

[tex]$$Expand out terms of the left hand side:$$(4 x+16)=3(x+6)$$Expand out terms of the right hand side:$$4 x+16=(3 x+18)$$Subtract $3 x$ from both sides:$$(4 x-3 x)+16=(3 x-3 x)+18$$$$\begin{aligned}&4 x-3 x=x: \\&x+16=(3 x-3 x)+18\end{aligned}$$[/tex]

[tex]\begin{aligned}&3 x-3 x=0: \\&x+16=18\end{aligned}$ \\\\\ Subtract 16 from both sides:$$\begin{aligned}&x+(16-16)=18-16 \\&16-16=0: \\&x=18-16\end{aligned}$$$$18-16=2$$Answer:$$x=2$$[/tex]

4(x+4) = 3(x+6)

4x + 16 = 3x + 18

4x - 3x = 18 - 16

x = 2

Answer:

234 in.2

Step-by-step explanation:

To find the area of the composite figure divide it into 3 shapes.

A large rectangle which is 10 by 20 so the area is 200.

A smaller rectangle which is 2 by 14 so the area is 28.

Finally, a small triangle which is 2 by 6 so the area is 6.

Add the areas together and the total area is 200 + 28 + 6 = 234.
