60 + 90
GCF = 30
(30 * 2) + (30 * 3) = 30(2 + 3) <== the correct way
The mistake Axial made was he did not pick the greatest common factor...he picked 3 instead of 30.
its <span>a numerical or constant quantity placed before and multiplying the variable in an algebraic expression</span>
<span>so 3,6,1</span>
This would be 2 and 12/17
Answer:
the probability is 0.0202
Step-by-step explanation:
The computation is shown below:
Given that
The Average life span = 17 hours
Standard deviation = 0.8 hours
Sample = 30 batteries
Sample mean = 16.7 hours
Now based on the above information
The probability is
![P (\bar x \leq 16.7) = P (\frac{\bar x - \mu}{(\frac{\sigma }{\sqrt{n} } )} \leq (\frac{16.7 - \mu}{(\frac{\sigma }{\sqrt{n} } )}\\\\= P(z\leq \frac{16.7-17}{\frac{0.8}{\sqrt{30} } } )\\\\= P(\leq -2.05)\\\\= 0.0202](https://tex.z-dn.net/?f=P%20%28%5Cbar%20x%20%5Cleq%2016.7%29%20%3D%20P%20%28%5Cfrac%7B%5Cbar%20x%20-%20%5Cmu%7D%7B%28%5Cfrac%7B%5Csigma%20%7D%7B%5Csqrt%7Bn%7D%20%7D%20%29%7D%20%5Cleq%20%20%28%5Cfrac%7B16.7%20-%20%5Cmu%7D%7B%28%5Cfrac%7B%5Csigma%20%7D%7B%5Csqrt%7Bn%7D%20%7D%20%29%7D%5C%5C%5C%5C%3D%20P%28z%5Cleq%20%5Cfrac%7B16.7-17%7D%7B%5Cfrac%7B0.8%7D%7B%5Csqrt%7B30%7D%20%7D%20%7D%20%29%5C%5C%5C%5C%3D%20P%28%5Cleq%20-2.05%29%5C%5C%5C%5C%3D%200.0202)
Hence, the probability is 0.0202
