Meg plotted the graph below to show the relationship between the temperature of her city and the number of people at a swimming pool:

Main title on the graph is Swimming Pool Population. Graph shows 0 to 30 on x axis at increments of 5 and 0 to 12 on y axis at increments of 1. The label on the x axis is Temperature in degree C, and the label on the y axis is Number of People at the Pool. Dots are made at the ordered pairs 2.5, 1 and 5, 2 and 7.5, 2 and 7.5, 3 and 7.5, 4 and 10, 5 and 10, 6 and 12.5, 6 and 15, 7 and 15, 8 and 17.5, 5 and 17.5, 7 and 20, 9 and 22.5, 7 and 22.5, 9 and 25, 11 and 27.5, 12.

Part A: In your own words, describe the relationship between the temperature of the city and the number of people at the swimming pool. (5 points)

Part B: Describe how you can make the line of best fit. Write the approximate slope and y-intercept of the line of best fit. Show your work, including the points that you use to calculate slope and y-intercept. (5 points)

Answers

Answer:

As the temperature increases, the number of people at the pool increases.

Part B: I think the line best fit can be one that starts at (0,0), and goes up until (28,12). The approximate slope would be 0.42, and the y-intercept is 0.

SLOPE:

(28,12)

y / x = m

12 / 28 = 0.42

Y-INTERCEPT:

​(0,0)

= 0

2. Lara collects shark's teeth. She has 72 teeth. She wants to put them in special cases. Each case can hold 10 teeth. How many cases should Lara buy? Draw a picture to find the answer. Then explain how you know your answer is correct.​

Answers

Answer:

Lara should buy 8 boxes

Step-by-step explanation:

To start we would need to do

72/10

since 72 isn't a multiple of ten we can round it down to 70, then do

70/10=7

since we still have two teeth, we can put them in their own box so

7+1=8

A circular wheel has a diameter of 42 cm. How far will it roll in 5
revolutions?​

Answers

Answer:

3.142

Step-by-step explanation:

Answer:

659.75 cm

Step-by-step explanation:

First, find the circumference with the formula C = 2[tex]\pi[/tex]r

The diameter is 42 cm, so the radius will be 21 cm

Plug in the radius into the equation and solve for C

C = 2[tex]\pi[/tex]r

C = 2[tex]\pi[/tex](21)

C = 131.95

Find how far it will roll by multiplying this by 5

131.95(5)

= 659.75

So, in 5 revolutions, it will roll 659.75 cm

help me pleaseee. I don’t understand why this wrong so it would be great if you could help?

Answers

Answer:

-4x + 5y = 40

Step-by-step explanation:

- move the expression to the left, so you want to get y - 4/5x = 8

-  multiply both sides so you get 5y - 4x = 40

- reorder the terms so you get -4x + 5y = 40

personally, I would change the signs afterwards to get 4x - 5y = -40, but the last thing I wrote was what was shown in that picture you sent. hope this helped :)

no. of lunches=total weight/weight of each lunch

=75/(3/2)

=75*2/3

Step-by-step explanation:

You need to divide 75 lb by 1 1/2 lb.

[tex] 75 \div 1 \frac{1}{2} = 75 \div \dfrac{3}{2} = \dfrac{75}{1} \times \dfrac{2}{3} = \dfrac{150}{3} = 50 [/tex]

What is the unit rate for the ratio 4/7: 8/21?

Answers

Answer:

The unit rate is 1.5

Step-by-step explanation:

Given

[tex]Ratio = 4/7 : 8/21[/tex]

Required

Determine the unit rate

To do this, we need to express the ratio as:

[tex]Ratio = m : 1[/tex]

Where m is the unit rate

[tex]Ratio = 4/7 : 8/21[/tex]

Express as fraction

[tex]Ratio = \frac{4/7 }{ 8/21}[/tex]

Solve

[tex]Ratio = \frac{4}{7} * \frac{21}{8}[/tex]

[tex]Ratio = 1.5[/tex]

Express as ratio

[tex]Ratio = 1.5 : 1[/tex]

Hence, the unit rate is 1.5

Yet this strangest of all things that ever came to earth from outer space must have fallen while I was sitting there, visible to me had I only looked up as it passed. Some of those who saw its flight say it travelled with a hissing sound. I myself heard nothing of that. Many people in Berkshire, Surrey, and Middlesex must have seen the fall of it, and, at most, have thought that another meteorite had descended. No one seems to have troubled to look for the fallen mass that night.
