![(8a^{-3})^\frac{2}{3}=(8 \cdot \frac{1}{a^3})^\frac{2}{3}=(\frac{8}{a^3})^\frac{2}{3}=\sqrt[3]{(\frac{8}{a^3})^2}=\sqrt[3]{\frac{64}{a^6}}=\frac{\sqrt[3]{64}}{\sqrt[3]{a^6}}=\frac{4}{a^2}](https://tex.z-dn.net/?f=%288a%5E%7B-3%7D%29%5E%5Cfrac%7B2%7D%7B3%7D%3D%288%20%5Ccdot%20%5Cfrac%7B1%7D%7Ba%5E3%7D%29%5E%5Cfrac%7B2%7D%7B3%7D%3D%28%5Cfrac%7B8%7D%7Ba%5E3%7D%29%5E%5Cfrac%7B2%7D%7B3%7D%3D%5Csqrt%5B3%5D%7B%28%5Cfrac%7B8%7D%7Ba%5E3%7D%29%5E2%7D%3D%5Csqrt%5B3%5D%7B%5Cfrac%7B64%7D%7Ba%5E6%7D%7D%3D%5Cfrac%7B%5Csqrt%5B3%5D%7B64%7D%7D%7B%5Csqrt%5B3%5D%7Ba%5E6%7D%7D%3D%5Cfrac%7B4%7D%7Ba%5E2%7D)
It doesn't equal any of the answers A, B, C.
The answer is D.
$25. 25 x 3 is 75. Plus the 100 is 175. 200 - 175 is $25
Answer:
To find the mean, you have to add all numbers together and divide them by the number of data points.
let me show what I mean:
The heights of the dogs are 600,470,170, 430,300.
Step-by-step explanation:
600+470+170+430+300.
1970.
Now we have to divide 1,970 by 5 ( because we are given 5 data points)
The mean is:
1970/5=394
Variance: First, arrange the data from least to greatest.
s2 = 27130
Standard Deviation: 164.71187
