Answer:

The underlying probability distribution can't be determined  with certainty in this case from the given data, but if we have to take one it would be most preferably the 'Normal Distribution'.

Step-by-step explanation:

The distribution is most probably 'Normal Distribution' as we know that it is the most general and common distribution of all and from the central limit theorem if there is a large sample from any  probability distribution with finite mean and variance, the sample mean approaches a suitable normal distribution and for most of the distributions when the parameters tend to a certain value or may be that is ∞ , the resulting distribution tends to a suitable normal distribution , but the underlying probability distribution can't be determined with certainty in  this case from the given data.

1st: split the 1 shape into 2 shapes. (spit across to where you see one right angle(top), and a trapezoid(bottom)

2nd: now what i did was fill that gap to where the total height is 9 and the total length is 7. ( if you don't want to do that it is fine )

3rd: for the top do 5 times 2 = 10

4th: for the bottom do 4 times 5 = 20

5th: add 10 (top) and 20 (bottom) = 30

Use compass directions to describe the Direction of a vector. The diagram is not drawn to scale
vekshin1
Using compass directions we simply describe the direction using the angle relative to N, S, E & W.

So in this case, the vector is travelling south west at an angle "41 degrees South of West."

Two pillars have been delivered for the support of a shade structure in the backyard. they are both ten feet tall and the cross
BartSMP [9]

The steps to determine whether the pillars have the same volume are;

First, we must know that the volume of an object of uniform surface area is the product of its Area and height.

The uniform area of each pillar is then evaluated and if equal;

Both pillars can be concluded to have the same volume.

We must first recall that for various shapes, the volume of the shape is a function of its height.

For example: a A cylinderical pillar and a rectangular prism pillar;

Volume of a cylinder = πr²h

Volume of a Cuboid = l × w × h

Since h = h.

Therefore, for both pillars to have the same volume; their Areas must be equal.

πr² = l × w

Solve for the roots in the equation below. In your final answer, include each of the necessary steps and calculations.
Nostrana [21]
x^3-27i=0
x^3=27i
x^3=27e^{i\pi/2}
x=\left(27e^{i\pi/2}\right)^{1/3}
x=3e^{i(\pi/2+2\pi k)/3}
x=3e^{i\pi(4k+1)/6}

where k\in\{0,1,2\}. This means you have

x=3e^{i\pi/6}=\dfrac32(\sqrt3+i)
x=3e^{i5\pi/6}=\dfrac32(-\sqrt3+i)
x=3e^{i9\pi/6}=-3i

as the solutions to the original equation.
