Well let's convert 2/3 to fraction of 6ths, by multiplying top and bottom by 2
Answer:
a)
b)
c)
With a frequency of 4
d)
<u>e)</u>
And we can find the limits without any outliers using two deviations from the mean and we got:
And for this case we have two values above the upper limit so then we can conclude that 1500 and 3000 are potential outliers for this case
Step-by-step explanation:
We have the following data set given:
49 70 70 70 75 75 85 95 100 125 150 150 175 184 225 225 275 350 400 450 450 450 450 1500 3000
Part a
The mean can be calculated with this formula:
Replacing we got:
Part b
Since the sample size is n =25 we can calculate the median from the dataset ordered on increasing way. And for this case the median would be the value in the 13th position and we got:
Part c
The mode is the most repeated value in the sample and for this case is:
With a frequency of 4
Part d
The midrange for this case is defined as:
Part e
For this case we can calculate the deviation given by:
And replacing we got:
And we can find the limits without any outliers using two deviations from the mean and we got:
And for this case we have two values above the upper limit so then we can conclude that 1500 and 3000 are potential outliers for this case
Answer:
Hi there!
Your answer is:
81
Step-by-step explanation:
First, simplify within parentheses.
-4-3-2 = -7-2 = -9
(-9)^2
The negative is within the parentheses, so it goes away when squared
(-9)^2 = -9× -9= 81
Hope this helps
Answer:
7.2 units
Step-by-step explanation:
Distance² = (Change in y)² + (Change in x)²
Distance² = (4 - -5)² + (-3 - -7)²
Distance² = 36 + 16
Distance² = 52
Distance = 7.211102551
Rounding off the answer to nearest tenth gives 7.2 units
To find the answer, you would have to count the lines horizontally first, then count the lines vertically starting from the origin (which is the point where all the lines meet in the middle) The point R is 2,3. K is 4,1 and G is 1, -1
I hope this helped! :D
