Part 1: Collect Data

In order to complete your assignment, you will need to collect some data.

The first five data points have been provided for you.

Age
(years) Number of U.S. States Named in 60 Seconds
5 7
15 42
25 49
35 35
65 50
Take a survey of at least five more people. You need a watch, stopwatch, or timer.
First, record the age of the person you are surveying.
Next, ask the person to name as many U.S. states as possible in 60 seconds. Keep a count, and watch your timer. Record each person’s data next to his or her age.
Repeat this with at least five people, and be sure to survey a range of ages, from young to old.
Part 2: Organize Your Data

Create a table of values using the age and number of U.S. states named in 60 seconds.
A graph is provided with the first five points plotted. Use your table to add your five data points to the scatter plot.

You may create a new graph from scratch, containing all 10 points, print the sample graph and add your data, or save the sample as an image and use a drawing program to add your data to the image. If you choose to print and draw by hand, you need to be able to scan and upload your work at the end of the project.

A coordinate plane is shown. The x axis is labeled age in years and the y axis is labeled number of U.S. States named in 60 seconds. Five data points are already plotted on the graph. These points are located at 5 comma 7, 15 comma 42, 25 comma 49, 35 comma 35, and 65 comma 50.


Draw a line of best fit through your scatter plot. Draw by hand on your printed graph or use a drawing program on your computer to create the line.
Part 3: Drawing Conclusions

How did you decide where to place your line of best fit? Describe your reasoning.
Based on your data, describe the relationship between age and the number of U.S. states a person can name in 60 seconds.
Do you see any areas in your data or points that could be considered clusters or outliers? Explain your answer in complete sentences.

The average speed for the whole trip is required.

The average speed of the car is 100 km/h.

Let [tex]x[/tex] be the total distance of the trip.

Distance traveled for 2nd half

[tex]60\times 1=60\ \text{km}[/tex]

[tex]x-\dfrac{3}{5}x=60\\\Rightarrow \dfrac{1}{5}x=60\\\Rightarrow x=300\ \text{km}[/tex]

Total time

[tex]t=2+1=3\ \text{hours}[/tex]

Average speed is given by

[tex]v=\dfrac{300}{3}\\\Rightarrow v=100\ \text{km/h}[/tex]

The average speed of the car is 100 km/h.

Step-by-step explanation:

Answer:

y = -6x + 2

Step-by-step explanation:

To find the slope, you do rise/run. To get to one point from another, you move one unit to the right, and six units down.

Now to find the y-intercept, you need to identify the point that meets in the y-axis. That would be 2.

Hope this helps!

Answer: y = -6x +2

Step-by-step explanation:

rise/run is 6/1 so slope = 6

D. It describes the distance between 6 and -6 on the number line.

Step-by-step explanation:

A. The absolute value of -6 is 6 because the absolute value is the positive or real number of a negative number.

B. The distance between -6 to 0 is 6.

C. [-6] = 6

D. The distance between 6 and -6 is 12.

-6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6

Answer:

Step-by-step explanation:

1) Check whether the graph is inclusive or exclusive. Inclusive graphs are equal to or greater/less than, whereas exclusive graphs are just greater/less than. A filled circle is inclusive, and a non-filled circle is exclusive. We see that in the graph, the circle is filled meaning it is inclusive. Secondly, we see that the number line goes forever when it is greater than(or equal to) 3. From these two pieces of information, we see that the answer is choice D.

Answer:

1. mean:10 median:11 mode:13

2. mean:30 median:35 mode: 20

Answer:

1. Mean: 10 Median: 11 Mode: 13

2. Mean: 26.7 Median: 20.5 Mode: 20

Step-by-step explanation:

1. Mean: 6+7+11+13+13 = 50 then, 50/5 = 10

Median: 6, 7, 11, 13, 13 in the middle: 11

6- crossed

13- crossed

7- crossed

13- crossed

That leaves 11!

Mode: 13 appears two times. All the other numbers only appear once.

2. Mean: 0+20+20+30+40+70 = 160 then, 160/6 = 26.7 ( rounded to nearest tenth)

Median: 0, 20, 20, 30, 40, 70

0- crossed

70- crossed

20- crossed

40- crossed

20- crossed

30- crossed

They all are crossed, but the last 2 to be crossed are 20 and 30. The middle of those two numbers is 20.5 therefore, the median is 20.5!

Mode: 20 appears twice while the rest only appears once.

I hope this helps, good luck! :)

Answer:

x = 3

Step-by-step explanation:

These angles are vertical angles. Vertical angles equals to on another but on the opposite side. Since they equal to another you do:

(10x + 1) = (12x - 5)

Add 5 on both sides:

10x + 6 = 12x

Subtract 10x on both sides:

6 = 2x

Divide 2 on both sides:

3 = x

Answer:

(10x+1)°=(12x-5)°. [vertically opposite angle]

1+5=12x-10x

6= 2x

3=x

therefore,x=3

Step-by-step explanation:

x+8=10

x−4=22

x÷3=6

7x=28

60=30+30=6+6+6+6+6+6+6+6+6+6

a=a

a=b,thenb=a

60=30+30,then30+30=60

ifa=bandb=c,thena=c

60=30+30

I don't get the question 2

Answer:

y = 2x - 4

Step-by-step explanation:

slope intercept form: y = ax + b

6x - 3y = 12

⇔ 6x - 12 = 3y

⇔ y = 2x - 4

Answer:

Yes it does!

Step-by-step explanation:

Side A: 12 ft

Side B: 14 ft

By the pythagorean theorem: A^2 + B^2 = C^2

so 12^2 + 14^2 = 340

C = sqrt(340) = 18.44 which makes the statement true that the walls form a right triangle!!

Answer: B. Graph of 2 lines that intersect at one point. Both lines are solid. One line passes through (-2,2) and (0,3) and is shaded below the line.

y < = 1/2x + 3...(-2,2)                y < = 1/2x + 3....(0,3)

2 < = 1/2(-2) + 3                        3 < = 1/2(0) + 3

2 < = -1 + 3                                3 < = 0 + 3

2 < = 2 (correct)                        3 < = 3 (correct)

The other line passes through points (0,1) and (1,-2) and is shaded above the line.

y > = -3x + 1...(0,1)            y > = -3x + 1...(1,-2)

1 > = -3(0) + 1                   -2 > = -3(1) + 1

1 > = 0 + 1                         -2 > = -3 + 1

1 > = 1 (correct)                 -2 > = -2 (correct)

Step-by-step explanation:

Answer:

this is hard sorry

Step-by-step explanation:

Answer:

A = (1/2)Pa = Pa/2

You can multiply both sides by 2 to eliminate the fraction on the right side:

2A = 2(Pa/2) = Pa

Then divide both sides by a (or multiply both sides by 1/a) to leave P alone on the right side:

(2A)(1/a) = 2A/a = (Pa)(1/a) = P

Rewriting:

P = 2A/a

You could also have divided by a first then multiplied by 2; which you should do first does not matter in this example.
