Answer:

- 0.62 + 8.35 + 3.9h =  - 6.55 + 1.1h \\  \\ 3.9h - 1.1h = - 6.55 + 0.62 - 8.35 \\  \\ 2.8h =  - 14.28 \\  \\ h =  \frac{ - 14.28}{2.8}  \\  \\ h =   \frac{ - 142.8}{28}  \\  \\ h =  - 5.1

I hope I helped you^_^

Given the following expressions:
Tamiku [17]

Step-by-step explanation:

Step 1:

A .    5 with an exponent of 3 times 5 with an exponent of -4

= 5^{3} * 5^{-4}  = 5^{3-4}= 5^{-1} = 1/5

B .   (1/4) with an exponent of 3 times (1/4) with an exponent of 2

= (1/4)^{3}  * (1/4)^{2} = (1/4)^{3+2} = (1/4)^{5} = 1/1024  

C. Same as above

D.  \\\frac{(-7)^{5} }{(-7)^{7} }  =  (-7)^{5-7}  =  (-7)^{-2}  =1/7^{2} = 1/49

Step 2 :

All the above expressions have a value between 1 and 2

Find the standard deviation of 21, 31, 26, 24, 28, 26
Vesnalui [34]

Given the dataset

x = \{21,\ 31,\ 26,\ 24,\ 28,\ 26\}

We start by computing the average:

\overline{x} = \dfrac{21+31+26+24+28+26}{6}=\dfrac{156}{6}=26

We compute the difference bewteen each element and the average:

x-\overline{x} = \{-6,\ 5,\ 0,\ -2,\ 2,\ 0\}

We square those differences:

(x-\overline{x})^2 = \{36,\ 25,\ 0,\ 4,\ 4,\ 0\}

And take the average of those squared differences: we sum them

\displaystyle \sum_{i=1}^n (x-\overline{x})^2=36+25+4+4+0+0=69

And we divide by the number of elements:

\displaystyle \sigma^2=\dfrac{\sum_{i=1}^n (x-\overline{x})^2}{n} = \dfrac{69}{6} = 11.5

Finally, we take the square root of this quantity and we have the standard deviation:

\displaystyle\sigma = \sqrt{\dfrac{\sum_{i=1}^n (x-\overline{x})^2}{n}} = \sqrt{11.5}\approx 3.39
