Answer is: 10
See the workup in photo below.
True answers for data in the plot are
The center is 13
The center is not 14
The Peak is 14.
It has three clusters
It is not symmetric to left or right it is bi-modal.
It is has a range from 10 to 15 most number of data points are 13 to 15.
Total number times Shelly waited is 16 times.
Step-by-step explanation:
- While taking cumulative frequency 56.75 percentage comes in 13%.
- It is the center point of the data.
- The 14 is not the center as it shows 93rd percent.
- It has three clusters 0-2 has one cluster,2-4 has 2nd cluster,5-8 third.
- It is not skewed on the left is has bi modal frequency has two heights.
- The person indeed waited for 16 times adding total dots.
- There was a zero 12 which created bi-modal distribution
Answer: The shortest side is 9ft
Step-by-step explanation: If the longest side is identified as 15 ft, then we already have our hypotenuse (the longest side in a right angled triangle).
If the shortest side is labelled as x, then the third side of the triangle would be labelled as 3x - 15 (15 less than three times the shortest side).
Now we have three sides of a triangle which we can label as 15, x and 3x - 15
By applying the Pythagoras theorem, AC² = AB² + BC²
(Where AC is the hypotenuse and AB and BC are the other two sides)
15² = X² + (3x-15)²
By expansion, (3x-15)² becomes 9x² - 90x + 225
Hence, 225 = X² + 9X² - 90X + 225
225 = 10X² - 90X + 225
Subtract 225 from both sides of the equation
10X² - 90X = 0
Factorize the left hand side of the equation by 10x
10x (x - 9)= 0
Therefore, either
10x = 0 OR
x - 9 = 0
If 10x=0, then x=0. OR
If x - 9 = 0, then x = 9
The length of the shortest side is 9ft.
