Please, you need to help yourself by looking up the meaning of these terms:  mean, median, mode, range FIRST.  How else will you know what you're looking for?

Example:  Find the mean of the integers 34 33 35 33 32 35 34 32.  To do this, just add them up, count how many you have, and then divide your sum by that count.  

Example:  Find the median of the integers 34 33 35 33 32 35 34 32.  First, arrange these integers in ascending order:  32 32 33 33 34 34 35 35.  Second, count them:  I see 8 integers.  Third, find the median:  It's the average of the middle two integers:  (33+34)/2 = 33.5

For z = 2cis 60°, find z4 in rectangular form.
a_sh-v [17]
By DeMoivre's theorem,

z=2\mathrm{cis}60^\circ\implies z^4=2^4\mathrm{cis}(4\times60)^\circ=16\mathrm{cis}\,240^\circ
z^4=16(\cos240^\circ+i\sin240^\circ)
z^4=16\left(-\dfrac12-i\dfrac{\sqrt3}2\right)
z^4=-8-i8\sqrt3

What is the recursive formula for this arithmetic sequence 6, -24, 96, -384
Artemon [7]

Answer:

Option A. a_{1} =6  a_{n}= a_{n-1}(-4)

Step-by-step explanation:

The given sequence in the question is 6,-24,96,-384.......n

and we have to give the recursive formula for this arithmetic sequence.

We can re write the sequence to make it more simpler

6,6(-4),(-24)(-4),(96)(-4).......n terms

Now we can say a_{1} = 6

and a_{n}= a_{n-1}(-4)

Therefore the recursive formula of the sequence is a_{1} = 6

a_{n}= a_{n-1}(-4)

At East Middle School, there are 585858 left-handed students and 609609609 right-handed students. The numbers of left- and right
lisabon 2012 [21]

Answer: C. Left-handed: 48 Right-handed: 504

E. Left-handed: 30 Right-handed: 315

Step-by-step explanation:

Here is the completed question:

At East Middle School, there are 58 left-handed students and 609 right-handed students. The numbers of left- and right-handed students at West Junior High are proportional to the numbers at East Middle School. Which of the following could be the numbers of left-handed and right-handed students at West Junior High?

A. Left-handed: 42 Right-handed: 483

B. Left-handed: 28 Right-handed: 378

C. Left-handed: 48 Right-handed: 504

D. Left-handed: 56 Right-handed: 560

E. Left-handed: 30 Right-handed: 315

Since it's direct proportion, we have to calculate the constant of proportionality which will simply be:

= 609 / 58 = 10.5

A. Left-handed: 42 Right-handed: 483

Constant = 483/42 = 11.5

Incorrect

B. Left-handed: 28 Right-handed: 378

Constant = 378/28 = 13.5

Incorrect

C. Left-handed: 48 Right-handed: 504

Constant = 504/48 = 10.5

Correct

D. Left-handed: 56 Right-handed: 560

Constant = 560/56 = 10

Incorrect

E. Left-handed: 30 Right-handed: 315

Constant = 315/30 = 10.5

Correct

Therefore, the correct options are C and E.
