Answer:
-10.5
Step-by-step explanation:
Pick two points that the line overlaps. We can see the points are on (0,63) (2,42) and (4,21). Lets use (2,42) and (4,21). To find the rate of change (m) the formula needed is y^2 - y^1 divided by x^2 - x^1. 21-42=-12 over 4-2=2. So we get -10.5 for the rate of change.
Answer:
rate of change is -10.5

Answer the written question only : Explain the meaning of both values in the context of the situation.
Slope and Y-intercept and what they both mean!
Answers
Answer:
see below
Step-by-step explanation:
Slope: The slope is [tex]\frac{rise}{run}[/tex], and this means that depending on how many students are increased, then the total number of flags also increases.
Y-intercept: When x=0, when there are 0 students, how many flags are already made.
The slope is
[tex]\frac{y2-y1}{x2-x1}[/tex]
[tex]\frac{44-8}{12-0}\\ =\frac{36}{12}\\ =3[/tex]
The y intercept is (0,8)
In this context, the slope represents that for every 3 students, 1 flag string is made. The y-intercept represents that when no students had made their own flag string, 8 flag strings had already been pre-made.
To answer the very last question (even though you didn't ask for it), the equation would be:
y=3x+8
Hope this helps additionally! :)
Answer:
The y-int=8 and the slope=3
Step-by-step explanation:
y-int in this situation means that they start with 8 flags.
slope means that each time there are 3 more students then there is 1 more flag. (I think)

In the data set below, what is the interquartile range?
23 58 58 64 76 87
Answers
Answer: IQR= 18
Step-by-step explanation:
First, you need to put the numbers in order from least to greatest, which they already are.
23, 58, 58, 64, 76,87
then, you draw an imaginary line down the middle of the numbers (between 58 and 64), and then you find the number in the middle of these. The Q1 is 58, and the Q3 is 76. In order to find the Interquartile range (IQR), you simply subtract the two.
76-58= 18
And you have your answer
Hope this helps!
Answer:
44
Step-by-step explanation:
First, we need to find the median in the data set.
It's between 58 and 64. To find the median, we add those two numbers and then divide by 2.
58 + 64 = 122
122 ÷ 2 = 61 (Mark this point in between the numbers on the data set)
median = 61
23, 58, 58, | 64, 76, 87
Now that we have the median, we have to find the upper quartile and the lower quartile in order to find the interquartile range.
Lets find upper quartile first. In order to do that, add up all the numbers to the right of the data set from the median point, then divide by 2.
64 + 76 + 87 = 227
227 ÷ 2 = 113.5
The same goes for the lower quartile (to the left).
23 + 58 + 58 = 139
139 ÷ 2 = 69.5
Lastly, to find the interquartile range, simply subtract the lower quartile from the upper quartile.
113.5 - 69.5 = 44
Therefore interquartile range = 44.

Step-by-step explanation:
According to the information, we can infer that some coordinates of this quadratic equation are: (-2, -3), (-1, -0.75), (0, 0), (1, -0.75), and (2, -3)
How to solve the quadratic equation?To solve the quadratic equation, we need to set the equation equal to zero:
-0.75x^2 = 0Now, we can divide both sides by -0.75 to isolate x^2:
x^2 = 0/(-0.75)x^2 = 0Taking the square root of both sides, we get:
x = 0Therefore, the solution to the quadratic equation s(x) = -0.75x^2 is x = 0.
According to the previous information, we can infer that the equation s(x) = -0.75x^2 represents a downward facing parabola. Here are 5 possible coordinates on this curve:

Step-by-step explanation:
3 feet on either end + 6 feet on either side + circumference of the circle
3 + 3 + 6 + 6 + circumference of the circle
18 + circumference of the circle
You can find the circle's diameter by subtracting 6 from 12. You get 6. You can find the radius by dividing the diameter by 2. You get 3.
The formula for circumference is 2·π·Radius
2 · π · 3 = 6 · π = 6 · 3.14 ≈ 36.85

The length of a cell phone is 1.4 1.4 inches and the width is 4.2 4.2 inches. The company making the cell phone wants to make a new version whose length will be 1.75 1.75 inches. Assuming the side lengths in the new phone are proportional to the old phone, what will be the width of the new phone?
Answers
If the side lengths of the new phone are proportional to the old phone, then we can set up a proportion:
1.4/4.2 = 1.75/x
Solving for x, we get:
x = 5.25 inches
So the width of the new phone will be 5.25 inches.

In the diagram of a fan below, CA = 9.5 in. this is the distance from the center to a point on the fans blade. what is the distance point A travels in one rotation of the fans blade
Answers
Answer:
About 59.66 inch
Step-by-step explanation:
To find the circumference you first have to find the diameter which is the double the radius. Since 9.5 is the radius of this circle, the diameter is, 9.5x2=19.
With the diameter of 19, you multiply the 19 with pie which is approximately 3.14. The answer is 19x3.14=59.66
C = 2 * pi * r
C = 2 * pi * 9.5
C = 59.69 in.
So point A travels a distance of approximately 59.69 inches in one rotation of the fan's blade.

Answers
Using the point-slope form: y - y₁ = m(x - x₁)
Plug in the values: y - 3 = -2(x - (-1))
Simplify: y - 3 = -2(x + 1)
Now, we can find the y value of the point:
y - 3 = -2(-1 + 1)
y - 3 = 0
y = 3
So, the y value of the point is 3.

Step-by-step explanation:
Box and Whisker Plot
box plot
Description
A Box and Whisker Plot (or Box Plot) is a convenient way of visually displaying the data distribution through their quartiles.
The lines extending parallel from the boxes are known as the “whiskers”, which are used to indicate variability outside the upper and lower quartiles. Outliers are sometimes plotted as individual dots that are in-line with whiskers. Box Plots can be drawn either vertically or horizontally.
Although Box Plots may seem primitive in comparison to a Histogram or Density Plot, they have the advantage of taking up less space, which is useful when comparing distributions between many groups or datasets.
Here are the types of observations one can make from viewing a Box Plot:
What the key values are, such as: the average, median, 25th percentile, etc.
If there are any outliers and what their values are.
If the data is symmetrical or not.
How tightly is the data grouped.
If the data is skewed and if so, in what direction.
Two of the most commonly used variation of Box Plot are: variable-width Box Plots and notched Box Plots.
let's say I start something at 10:20 pm on the 18 of April and I finish that thing at 12:06 am 19th of April. How much time did I spend doing that thing (Would like a explaination)
Answers
First, let's convert the start time to 24-hour format, which is 22:20. Then, we can subtract 22:20 from 00:06 (12:06 am).
00:06
- 22:20
____
01:46
Therefore, you spent 1 hour and 46 minutes doing that thing.
1 hour is 60 minutes, at 11:00 pm you would have spent 40 minutes doing what you had started so from 10:20pm to 11:00pm 40 minutes passed. Then you would add 60 minutes from 11:00pm to 12:00am.
( although 12:00 is marked as we know that 12:00 am marks the earths rotation of a day which means at 12:00am the sun has begun to reach your point of rotation on earth) from 12:00am to 12:06am it has past 6 minutes
40mins + 60mins+6mins=106mins
1 hour goes into 106mins so
106-60= 46
You spent 1 hour and 46mins
