Please answeer these x

Answer 1

to find the mean add the numbers up and divide by the number of numbers

[sqrt (27) + sqrt(48) + sqrt(75)]/3=

[sqrt(9)sqrt(3) + sqrt(16)sqrt(3) + sqrt(25) sqrt(3)]/3=

[3sqrt(3) +4sqrt(3) +5sqrt(3)]/3=

[12sqrt(3)]/3=

4 sqrt /3

12 cos 30 + 2 tan 60

12 (sqrt(3)/2) + 2(sqrt(3))

6sqrt(3) +2sqrt(3)

8sqrt(3)
