first, sort the numbers from lowest to highest.

5,5,6,7,8,9,10,*10,12*,14,15,17,18,18,18,20

the median is the number in the middle of the data

average if you need to (10+12 and divide by 2)

Answer:

Step-by-step explanation:

I prefer the equation in this format

$\frac{3 |m - 2 {n}^{2} | }{4}$

substitute -4 for m and 6 for n

$\frac{3 | - 4 - 2( {6}^{2}) | }{4}$

square the 6 then multiply by 2

$\frac{3 | - 4 - 72| }{4}$

solve inside the absolute value then multiply by 3

$\frac{3 | - 76| }{4}$

$\frac{228}{4}$

divide by 4

$57$

Solve using demoivres theorem

pashok25 [27]

It's difficult to make out, but I think the task is to expand

$(\sqrt3-i)^4$

Write the number in polar form first:

$\sqrt3-i=2e^{-i\pi/6}$

By DeMoivre's theorem, you have

$(\sqrt3-i)^4=\left(2e^{-i\pi/6}\right)^4=2^4e^{-i4\pi/6}=16e^{-i2\pi/3}$

and converting back to Cartesian form, this number is equivalent to

$16\left(\cos\dfrac{2\pi}3-i\sin\dfrac{2\pi}3\right)=16\left(-\dfrac12+-\dfrac{\sqrt3}2\right)=-8(1+i\sqrt3)$

A hiking trail down the side of Mt. Tom drops a vertical distance of 60 meters over a horizontal distance of 300 meters. What is

Lady_Fox [76]

Answer:

Step-by-step explanation:

Slope of the trail is expressed as;

Slope = vertical distance/horizontal distance

Given

Vertical distance = 60metres

Horizontal distance= 300metres

Substitute

Slope = 60/300

Slope = 6×10/30×10

Slope = 6/30

Slope = 6×1/6×5

Slope = 1/5

Hence the slope of the trail in reduced fraction is 1/5

In the equation r(65 = .45, p < .05, what are the degrees of freedom?

WINSTONCH [101]

I would suggest that the answer is 65.
Degrees of freedom, in statistics, determines the number of values that can be able to vary. Showing the independent variable factors.
