Using exponent laws please answer this
hram777 [196]

Answer:

  see below

Step-by-step explanation:

In addition to the exponent rule ...

  (a^b)^c = a^(bc)

it is helpful to know the first few powers of some small integers.

  5^3 = 125

  9^2 = 81

  4^3 = 64

  2^6 = 64

__

  1. 125^3 = (5^3)^3 = 5^(3·3) = 5^9
  2. 81^7 = (9^2)^7 = 9^(2·7) = 9^14
  3. (1/64)^3 = ((1/4)^3)^3 = (1/4)^(3·3) = (1/4)^9
  4. (1/64)^3 = ((1/2)^6)^3 = (1/2)^(6·3) = (1/2)^18

Ede4ka [16]

Answer:

xbar=14.3421

s=18.7920

Step-by-step explanation:

sample mean

xbar = ∑x/n = (0.20 + 0.73 + 0.99 +1.29 + 2.84 + 3.34 + 4.07 + 4.69 + 4.86 + 6.53 + 7.45 + 8.07 + 8.21 + 12.39 + 31.67 + 32.53 + 33.92 + 36.00 +72.72)/19=14.3421

where n stands for the size of the sample

sample deviation

s= \sqrt{}(∑(x_i - x bar )^2/(n-1)) = \sqrt{}(∑x_i^2 - n*xbar^2)/(n-1)) = \sqrt{}(0.20^2 + 0.73^2 + 0.99^2 +1.29^2 + 2.84^2 + 3.34^2 + 4.07^2 + 4.69^2 + 4.86^2 + 6.53^2 + 7.45^2 + 8.07^2 + 8.21^2 + 12.39^2 + 31.67 ^2+ 32.53^2 + 33.92^2 + 36.00^2 +72.72^2-19*14.3421^2)/(19-1)) = 18.7920
