What is the standard deviation of the following data? If necessary, round your answer to two decimal places. 82, 44, 67, 52, 120

Dominik [7]

Number of values = 5 (There are 5 values given)

Mean = (82 + 44 + 67 + 52 + 120)/5 = 73

Variance = (1/5) [(82-73)^2 + (44-73)^2 + (67-73)^2 + (52-73)^2 + (120-73)^2] = 721.6

Standard deviation = sqrt (721.6) = 26.86

For problems 12 - 14, Determine whether each sequence appears to be an

marshall27 [118]

Step-by-step explanation:

⇒12)It is an arithmetic sequence.

d=2-1=3-2=4-3=1

a(n) = a +(n-1)d

a(n) = 1+(n-1)1

The next three terms:

a(6) = 1+(6-1)1=6

a(7) = 1+(7-1)1=7

a(8) = 1+(8-1)1=8

⇒13)It is an arithmetic sequence.

d=0-3=-3-0=-6+3=-3

a(n) = a +(n-1)d

a(n) = 3+(n-1)-3

The next three terms:

a(5) = 3+(5-1)-3=-9

a(6) = 3+(6-1)-3=-12

a(7) = 3+(7-1)-3=-15

⇒14)It is not an arithmetic sequence.

⇒15) a(50) = 10 +(50-1)5

=255

anastassius [24]

Answer:

so what you do is you divide 30 by 4.5 then when you get the density you divide that by the 10 pennies so you get the density of 1 penny
