There are a lot of questions and work here, I can help you get started in the right direction.
On the left, you have the heights for Soil A. On the right, you have the height for Soil B. Looking at the overlap, there are a lot of heights in the 60's and 70's for both.
To calculate the mean, add up all the values and divide by the total.
For the MAD, you have to subtract each value from the mean. Then, take the absolute value of it. Finally, find the mean of those values.
The one with the higher MAD is more variable.
Answer:
f(x) = 10500sin(π/6(x -3)) +39500
Step-by-step explanation:
The average of the maximum and minimum revenue is the vertical offset of the function, parameter D.
D = (50,000 +29,000)/2 = 39,500
The amplitude of the function is the difference between the maximum and the offset.
A = 50,000 -D = 50,000 -39,500 = 10,500
The horizontal scale factor B is a number that will be equal to 2π when x-C = 12:
12B = 2π
B = π/6 . . . . . . divide by 12
The horizontal offset is such that revenue is neutral and increasing at the value x=C. That will be in the month of March, when x=3, so C=3.
Now we have all the parameters, so we can write the equation:
f(x) = 10500sin(π/6(x -3)) +39500
Multiplying 20 by 320% is the same thing as multiplying 20 by 3.2, or 20(3.2)=64. Hope this helped!
Answer:
Each of the legs of isosceles right triangle is 5
Step-by-step explanation:
Watch the attached figure for the isosceles right angled triangle
Looking at the figure we see that AB=5√6 and BC=CA
According to the Pythagorean theorem the square of the hypotenuse is equal to the sum of the squares of the other two sides of a right triangle.
1) Applying the Pythagorean theorem to the isosceles right triangle, we have

2) Let BC=a and CA=a as they both are equal
So,

=> 
=> 
=>
(since √6*√6 = (√6)²= 6)
=> 
3) Dividing both sides by 2, we get

4) Cancelling out the 2's on the left, we get
= 75
5) Taking the square root on both sides, we have

=> a = 5
So,
Each of the legs of isosceles right triangle is 5
