The data from 200 endothermic reactions involving sodium bicarbonate are summarized as follows: calculate the probability mass f
In-s [12.5K]
Given the table below which contains data from 200 endothemic reactions involving <span>sodium bicarbonate:

\begin{tabular}&#10;{|c|c|}&#10;Final Temperature Conditions&Number of Reactions\\[1ex]&#10;266 K&48\\&#10;271 K&60\\&#10;274 K&92&#10;\end{tabular}

We find the probability distribution function as follows:

Let X denote the final temperature, then
</span>
<span>P(X = 266) =  \frac{48}{200} =0.24\\ \\ P(X = 271) =  \frac{60}{200} =0.3\\ \\ P(X = 274) =  \frac{92}{200} =0.46</span>

What is 3.3(x-8)-x=1.2
11Alexandr11 [23.1K]
Multiply 3.3 by everything in the parenthesis.

3.3x - 26.4 - x = 1.2

Combine like terms.

2.3x - 26.4 = 1.2

Add 26.4 to both sides.

2.3x = 27.6

Divide 2.3 on both sides.

x = 12

Hope this helps!
