What is the additive inverse of the complex number 13-2

Svet_ta [14]

Answer:

-13 + j*2

Step-by-step explanation:

The additive inverse of a complex number x = a +j*b

is a number y, such that

x + y = 0

This means that

y = -x = - a - j*b

Therefore

The additive inverse of 13 - j*2 is equal to

-(13 - j*2) = -13 +j*2

Answer:

So, the interquartile range is IQR=22.5.

Step-by-step explanation:

Let us write the numbers in ascending order:

34, 37, 38, 40, 44, | 46, 50, 51, 55, 56, |

57, 61, 62, 65, 65, | 68, 68, 72, 73, 76.

We calculate quartile 1:

$Q_1=\frac{44+46}{2}=45$

We calculate quartile 2:

$Q_2=\frac{56+57}{2}=56.5\\$

We calculate quartile 3:

$Q_3=\frac{65+68}{2}=67.5\\$

We calculate the interquartile range:

$IQR=Q_3-Q_1\\\\IQR=67.5-45\\\\IQR=22.5$
