-3/8 -1/6
Find the Least Common Denominator (LCD) of 3/8, 1/6. In other words, find the Least Common Multiple (LCM) of 8,6.
LCD=24
Make the denominators the same as the LCD.
- 3x3/8x3 - 1x4/6x4
Simplify. Denominators are now the same
-9/24 - 4/24
Join the denominators
-9-4/24
Simplify
-13/24
Answer:
10 sqrt(269) = c
164.0121947 = c
Step-by-step explanation:
The diagonal is the hypotenuse of the right triangle
The length and width are the legs of the right triangle
We can use the Pythagorean theorem
a^2 + b^2 =c^2
100^2 + 130^2 = c^2
10000+16900 = c^2
26900 = c^2
Take the square root of each side
sqrt(26900) = sqrt(c^2)
sqrt( 269) sqrt(100) = c
10 sqrt(269) = c
164.0121947 = c
The error made while find the mean absolute deviation was: C. When calculating the distances to the mean, the student forgot to take the absolute values.
<h3>What is the Mean Absolute Deviation?</h3>
The mean absolute deviation is simply the average of the sum of the "absolute difference" of the mean and each data point.
In the calculation of the student, after getting the difference of the mean and each data point, the student failed to take the absolute value, and still kept the minus sign included.
Therefore, the error was: C. When calculating the distances to the mean, the student forgot to take the absolute values.
