Answer:
Many of the rocks in Earth's crust and interior undergo this process of radioactive decay . This process produces subatomic particles that zip away, and later collide with surrounding material inside the Earth. Their energy of motion is converted to heat.
Answer:
It's division because to get x by itself, you need to divide both sides. X = 9
Step-by-step explanation:
6x = 54
Divide both sides by 6
54/6 = 9

Answer:
25.5 days
Step-by-step explanation:
Mean number of days (μ) = 22 days
Standard deviation (σ) = 6 days
Z-score for the 72nd percentile (according to tabulated values) = 0.583
The z-score for any number of days, X, is determined by:
![z=\frac{X-\mu}{\sigma}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7BX-%5Cmu%7D%7B%5Csigma%7D)
The value of X that is greater than 72% of the trial times is:
![0.583=\frac{X-22}{6}\\ X=25.5\ days](https://tex.z-dn.net/?f=0.583%3D%5Cfrac%7BX-22%7D%7B6%7D%5C%5C%20X%3D25.5%5C%20days)
Therefore, 72% of all of these types of trials are completed within 25.5 days.
