Serhud [2]

Arranging data in ascending order to identify the outlier and calculate the mean

Step-by-step explanation:

Given the data as: [4, 1, 3, 10, 18, 12, 9, 4, 15, 16, 32]

Arrange in ascending order

                               [1, 3, 4, 4, 9, 10, 12, 15, 16, 18, 32 ]

The outlier is 32

Finding the mean;

Mean=sum of data set/number of data set

Sum= 1 + 3+ 4+ 4+ 9+ 10+ 12+ 15+ 16+ 18+ 32=124

Number of data set=11

(3-4i)(-2-21) multiply
evablogger [386]

Answer:

-69 +92 i (here 'i' is imaginary value)

Step-by-step explanation:

step:-

Given (3-4 i)(-2-21)

on multiplication, we get

(3-4 i)(-2-21) = 3(-2) -3(21) - 4 i (-2) +4 i(21)

                    = -6 -63 + 8 i +84 i

                    = -69 +92 i

-69 + 92 i is a complex number.

real part x = -69

imaginary part y = 92
