In a data set, the proportion of items that are in a particular category is called the Relative Frequency
<h3>What is Relative Frequency ?</h3>
Frequency mean how often an event can occur , an relative frequency means how many times that event will occur with respect to the total number of events.
For determining Relative frequency , we need to know the frequency for a particular event and the total number of event.
The proportion of items that are in a particular category is called the <u>Relative Frequency</u>.

Answer:
range = 7.87
X = 62.12, X²= 164.3516
mean = 1.2424
variance = 1.779
standard deviation = 1.33379
coefficient of variation = 107.3559%
Step-by-step explanation:
a.) The range =
highest number - lowest number
= 7.89 - 0.02
= 7.87
b.) from the attachment I solved for X and X²
∑X = 62.12
∑X² = 164.3516
c.)
the mean = ∑x/n
n = 50
= 62.12/50
= 1.2424
variance =
σ² = [∑x²-(∑x)²/n] / n-1
= [164.3516 - (62.12)²/50] / 50-1
= 164.3516 - 77.17788/49
= 87.173712/49
= 1.779
standard deviation = √σ
= √1.779
= 1.33379
d. coefficient of variation
= σ/mean * 100
= 1.33379/1.2424 * 100
= 107.3559
This number tells us that the the standard deviation of the time to failure is larger than the average time. option 3 is the correc4 answer here
We have to write down some values that we can see from the graph. At x=0, the value is 100. At x=1, the y-value is 150 and at x=2 the graph has a value of a little over 200. We see also that this is an exponential graph, so we might assume that there is a specific ratio from each x-value to the next. We get that this ratio is 150/100=1.5. Hence, the quantity increases by 1.5 or 150% every time we add 1 to the x-coordinate. The 2 first sentences are correct. If an amount increases by 50% after a year, at the end of the year there is 150% of it (we need to add the initial capital which is 100%). Thus the graph here has as x-axis years and as y-axis money. The same concept holds for the 2nd sentence. The 3rd sentence is wrong because the value here is not multiplied but added. This would produce a linear graph. Sentence 4 has the wrong ratio; if that was true, then at x=1 we would have 200 oranges, not 150. For the same reason option 5 is wrong; 150*100=15000, not 150.
Answer:
231.7 cm^2
Step-by-step explanation:
We can find the area by adding the area of the rectangle to the area of the 2 triangles.
The rectangle is
7+7+7 by 9
21 by 9
A = length * width
A = 21*9
A = 189
The triangles are identical so we find the area of one of them and multiply by 2
The base is 7 and the height is 6.1
A = 1/2 b*h
but since we have 2 of them
2A = 2*1/2 b*h
2A = b*h
2A = (7* 6.1)
= 42.7
Add the rectangles area to the area of the two triangles
189 + 42.7
231.7 cm^2
A point is an exact location.
It has no length, width, or height.
It has no area or volume.
It has no mass, shape, or other physical properties.
As a model ...
-- you could use the period at the end of a sentence printed on paper.
It looks like this ==> ·
-- You could use the point of a very sharp pencil.
-- You could use the tiny dot that the point of
a very sharp pencil makes on paper.
-- You could use the point of a pin.
-- You could use the tiny hole that the point of
a pin makes in a sheet of paper.
These are all bigger than a real point. They all have a little bit of size,
length, width, height, and you can see them. But they get the idea across.
(They 'make the point'.)
