Solution:
The description about the graph is:
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 Sweaters Sold. Dots are made at the ordered pairs 0, 12 and 2.5, 10 and 2.5, 11 and 5, 10 and 7.5, 9 and 7.5, 10 and 10, 7 and 12.5, 6 and 12.5, 8 and 15, 4 and 15, 7 and 17.5, 5 and 20, 1 and 20, 3 and 22.5, 9 and 25, 1 and 27.5, 1.
Part A: The relationship between the temperature of the city and the sale of sweaters in the city can be found by drawing the line of best fit.
If you will draw line through , (12.5,6) and (15,4), it will best represent line of best fit, because most of points on same and opposite side of line are equidistant from each other.
Equation of line passing through two points,[tex](x_{1},y_{1}),(x_{2},y_{2})is, \frac{y-y_{1} }{x-x_{1} } = \frac({y_{2} - y_{1}})({x_{2}-x{1} })[/tex]
Equation of line passing through (12.5,6) and (15,4) is given by
[tex]\frac{y-6}{x-12.5} = \frac{6-4}{12.5-15}[/tex]
[tex]2x-25=-2.5+15[/tex]
[tex]2x+2.5y=40[/tex]
[tex]20x+25y= 400[/tex]
[tex]4x+5y=80[/tex]
Part B: Description of line of best fit
A line of best is the line which passes through all or some points or only through a single point, which describes the relationship between x and y values of data set. The line passes through (12.5,6), (15,4),and (7,10) that is three points.
(C) 4 x + 5 y=80
5 y= - 4 x +80
[tex]y=\frac{-4x}{5}+16[/tex]
Slope [tex]= \frac{-4}{5}[/tex], Y- intercept = 16

Which space mission from Earth traveled to the moon at a faster pace, Apollo 11 or Luna I?
Apollo 11 - 8.35 * 10^1 kilometers/minute
Luna l - 1.76 * 10^2 kilometers/minute
Answer:
Apollo 11 - 8.35 * 10^1 kilometers/minute
Step-by-step explanation:
The primary objective of Apollo 11 was to complete a national goal set by President John F. Kennedy on May 25, 1961: perform a crewed lunar landing and return to Earth.
Additional flight objectives included scientific exploration by the lunar module, or LM, crew; deployment of a television camera to transmit signals to Earth; and deployment of a solar wind composition experiment, seismic experiment package and a Laser Ranging Retroreflector. During the exploration, the two astronauts were to gather samples of lunar-surface materials for return to Earth. They also were to extensively photograph the lunar terrain, the deployed scientific equipment, the LM spacecraft, and each other, both with still and motion picture cameras. This was to be the last Apollo mission to fly a "free-return" trajectory, which would enable a return to Earth with no engine firing, providing a ready abort of the mission at any time prior to lunar orbit insertion.
Answer:
The average speed of Luna I was 1.76 x 10^2 kilometers/minutes. The average speed of Apollo 11 was 8.35 x 10^1.
The average speed of Luna I was greater than the average speed of Apollo 11. So, Luna I traveled at a faster pace than Apollo 11.
Step-by-step explanation:
Ruby's water bottle holds 1 9/10 liters of water. Noland's water bottle holds 2 3/5 liters of water. Noland says that his bottle holds about 1/2 liter more water than Ruby's. Round to the nearest fourth, 1 9/10 is closest to ------- and 2 3/5 is closest to -------- . The difference between the bench mark is --------- , so Nolan's estimate is ----------.
Answer: 2, 2 1/2, 1/2, correct
Step-by-step explanation: the first fraction is equal to 1 36/40, so it is closer to 1 40/40 than 1 30/40. The second fraction is equal to 2 12/20, so it is closer to 2 10/20 than 2 15/20.

Find the Area of the Shape pls help
Answer:
G. 1560 ft^2
Step-by-step explanation:
formula for area of a trapezoid=h/2(b1+b2)
split the trapezoid into two triangles first, and identify the two bases plus the height.
height:30 ft
base 1=68
base 2=36
**note, the 34 is basically irrelevant
30/2(68+36)
15(104)=1560
PLS HELP BRAINLIEST FOR CORRECT ANSWER+20 POINTS
Answer:
120 blocks total
Step-by-step explanation:
All of the little cubes have side length 2" Thus, the 11" height of the box cannot be used entirely: we waste the top 1" because the five layers of little cubes reach only to 10" from the bottom.
Start at the bottom of the box. The dimensions of the bottom are 12" by 8". Along the longer side we can lay 6 blocks (which add up to 12" and are 2" wide. We can add 3 more such rows to fill the available 8" width of the box bottom. That's 6*4, or 24 blocks.
We can add 4 more 6 block by 4 block layers before we have the maximum 5 layers stacked in the box.
5 layers times 24 blocks per layer comes to 120 blocks total.

What is the area of triangle i? Show your calculation
please dont use me for points
Answer:
3 square centimeters.
Step-by-step explanation:
The measurements are 4 cm by 1.5 cm, so you can use the formula for area of a triangle (area = 1/2 * base * height) to figure it out.
Plug in base = 4, height = 1.5:
area = 1/2* 4 * 1.5 = 2 * 1.5 = 3.
The area is 3 sq. cm.

Help please 6th grade math
Answer:
A and C
Step-by-step explanation:
By letting x = 0 she is eliminating the terms in x , rather than simplifying
A
9x - 3x - 4 ← collect like terms
= 6x - 4
B
12x - 4 ← already in simplest form
C
5x + x - 4 ← collect like terms
= 6x - 4
Thus A and C are equivalent expressions

In one paragraph, using your own words, describe a commercial you have seen recently and tell what the commercial was selling and what the hidden message was in it.
Answer:
A commercial I have seen recently was the Grub Hub commercial. The commercial was advertising all the types of food you could possibly buy with Grub Hub. It seems their point in this commercial was to bring consumers (people who buy the food) in and purchase their food using the Grub Hub app. Grub Hub did this by making jokes and trying to be funny with the commercial. The people in the commercial were dancing and smirking while they smacked on the "delicious" food and apparently the food was so good and tasty that even a PREGNANT woman did the splits. So basically it was not a normal commercial it was... really special. The hidden message was that it's "better" than Uber.

Using Abdul's simulation, what is the probability of rolling a 2 on the number cube and the coin landing heads up? (5 points)
Answer:
450/10000
Step-by-step explanation:
Probability of rolling a 2 : 10/100
Probability of getting heads up : 45/100
Probability of both together : 10/100 * 45/100 = 450/10000

The figure is the net for a rectangular prism.
What is the surface area of the rectangular prism represented by the net?
please help
TωT
Answer:
544 cm^2
Step-by-step explanation:
You can see that the figure is made of 6 different rectangles, which would become the sides of the prism if it was 3D.
The top rectangle has a length of 16 cm and a width of 8 cm. 16 x 8 = 128 so this side has an area of 128 square cm
The one directly below that has the same length (16 cm) and a width of 6 cm. 16 x 6 = 96 so its area is 96 square cm
On either side of the previous one there is a 6 by 8 rectangle. 6 x 8 = 48. Remember, there are two sides with an area of 48 cm^2
Below that we have another 16 by 8 rectangle and then another 16 by 6 rectangle.
So your total surface area would be 128 + 96 + 48 +48 + 128 + 96
or 544 square cm
