The Mean Absolute Deviation for the following data: 6, 1, 3, 8, 5, 11, 1, 5 is 2.5
What is mean absolute deviation?The mean absolute deviation of a dataset is the average distance between each data point and the mean.
mean absolute deviation = [tex]\frac{summation|x-mean|}{n}[/tex]
where
n = number of termsTherefore, let's calculate the mean first.
Arrange the data in ascending order.
1, 1, 3, 5, 5, 6, 8, 11
mean = 1 + 1 + 3 + 5 + 5 + 6 + 8 + 11 / 8 = 40 / 8 = 5
Therefore, let's calculate the distance between each dat point and mean.
|1 - 5| + |1-5| + |3-5| + |5-5| + |5-5| + |6-5| + |8-5| + |11-5|
4 + 4 + 2 + 0 + 0 + 1 + 3 + 6 = 20
Hence,
mean absolute deviation = 20 / 8 = 2.5

A car rental company's standard charge includes an initial fee plus an additional fee for each mile driven. The standard charge s (in dollars) is given by the function S= 0.40M + 18.95 , where M is the number of miles driven.
The company also offers an option to insure the car against damage. The insurance charge I (in dollars) is given by the function I = 0.25M + 5.70.
Let C be the total charge (in dollars) for a rental that includes insurance. Write an equation relating C to M . Simplify your answer as much as possible.
C= ?
Answer:
Simplified answer = C = $0.65m + $24.65
Step-by-step explanation:
Add the two initial charges together (from the insurance and the standard charge) and you get $24.65. Then add the two charges together for each mile which is $0.65 per mile. Therefore, the total charge on the car is $24.65 + 65 cents every mile driven.

What is the definition of a Function?A function assigns the value of each element of one set to the other specific element of another set.
A function has to be plot which has the value of f(x) as 3 and -9. Here, 3 and -9 are the solution of the function. Thus,
x=3
x-3=0
The second solution is,
x=-9
x+9=0
Multiply both factor for the function as,
f(x)=(x-3)(x+9)
f(x)=x²+9x-3x-27
f(x)=x²+6x-27
This is the required function. The graph of this function is attached below.
Thus, the equation of the function f with solution 3, -9 is x²+6x-27 and the graph of this equation with the use of drawing tools is attached below.

If the geometric mean of a and 12 is 8root6, find the value of a.
The value of a, when the geometric mean of two numbers a and 12 is 8√6 is equal to the number 32.
How to find geometric mean?Geometric sequence is the sequence in which the next term is obtained by multiplying the previous term with the same number for the whole series.
For Geometric sequence, the value of geometric mean can be found out using the following formula,
[tex]x=\sqrt{ab}[/tex]
Here, (a and b) are the two terms of geometric sequence.
The geometric mean of a and 12 is 8√6. Thus,
[tex]x=8\sqrt{6}[/tex]
[tex]b=12[/tex]
Put this value in formula to find the value of a,
[tex]8\sqrt{6}=\sqrt{a\times12}\\[/tex]
Square both side of equation,
[tex](8\sqrt{6})^2=(\sqrt{a\times12})^2\\64\times6=12a\\a=\dfrac{64\times6}{12}\\a=32[/tex]
Thus, the value of a, when the geometric mean of two numbers a and 12 is 8√6 is equal to the number 32.

the amount of water in a bottle is reduced by 85% to 120 millimeters. how much water was originally in the bottle?
A percentage is a way to describe a part of a whole. The amount of water in the bottle originally is 800 mm.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Let the water in the bottle at the very initial be x.
Given that after reduction the amount of water in the bottle is 120 millimetres, also, the water is reduced by 85%, therefore, the amount of water that will be in the bottle is 15% of the original.
Water in the bottle = 15% of x
120 mm = 0.15 × x
x = 800 mm
Hence, the amount of water in the bottle originally is 800 mm.
