Answer: 2.14 %
Step-by-step explanation:
Given : pH measurements of a chemical solutions have
Mean : ![\mu=6.8](https://tex.z-dn.net/?f=%5Cmu%3D6.8)
Standard deviation : ![\sigma=0.02](https://tex.z-dn.net/?f=%5Csigma%3D0.02)
Let X be the pH reading of a randomly selected customer chemical solution.
We assume pH measurements of this solution have a nearly symmetric/bell-curve distribution (i.e. normal distribution).
The z-score for the normal distribution is given by :-
![z=\dfrac{x-\mu}{\sigma}](https://tex.z-dn.net/?f=z%3D%5Cdfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D)
For x = 6.74
![z=\dfrac{6.74-6.8}{0.02}=-3](https://tex.z-dn.net/?f=z%3D%5Cdfrac%7B6.74-6.8%7D%7B0.02%7D%3D-3)
For x = 6.76
![z=\dfrac{6.76-6.8}{0.02}=-2](https://tex.z-dn.net/?f=z%3D%5Cdfrac%7B6.76-6.8%7D%7B0.02%7D%3D-2)
The p-value =![P(6.74](https://tex.z-dn.net/?f=P%286.74%3Cx%3C6%2C76%29%3DP%28-3%3Cz%3C-2%29)
![P(z](https://tex.z-dn.net/?f=P%28z%3C-2%29-P%28z%3C-3%29%3D0.0227501-%200.0013499%3D0.0214002%5Capprox0.0214)
In percent, ![0.0214\times=2.14\%](https://tex.z-dn.net/?f=0.0214%5Ctimes%3D2.14%5C%25)
Hence, the percent of pH measurements reading below 6.74 OR above 6.76 = 2.14%
The answer is 2670.57 and yes im sure this is right i just finished my quiz! (Please make the answer the brainliest!)
Make the denominator the same, so multiple 3/10 by 2, which produces 6/20. Take 6/20 and subtract 7/20 because adding a negative number is the same as subtracting a positive number. the Answer is -1/20.
Answer:
It is C. 233 because if you multiply 5x5x5 thats 125
If you multiply 12x3x3, its 108. So add 108+125 and that will be your final answer. Hope this helps and if so then please mark as brainliest. Remember that volume= length x width x height.
