The ages of the employees at Solar Systems, Inc. is normally distributed with a mean of 32.7 years and a standard deviation of 1

svetoff [14.1K]

Answer:

6.7% of employees at Solar Systems, Inc. are younger than 30 years old

Step-by-step explanation:

The mean of ages of the employees at Solar Systems is 32.7 years

Mean = $\mu = 32.7$

Standard deviation = $\sigma = 1.8 years$

We are supposed to find What percentage of employees at Solar Systems, Inc. are younger than 30 years old i.e.P(x<30)

So, $Z=\frac{x-\mu}{\sigma}$

$Z=\frac{30-32.7}{1.8}$

Z=-1.5

Refer the z table for p value

So,p value = 0.0668

So P(x<30)=0.0668= 6.68% = 6.7%

So, 6.7% of employees at Solar Systems, Inc. are younger than 30 years old

Carbon-14 has a half-life of 5730 years. In a plant fossil, you find that the 14C has decayed to 1/8.00 of the original amount.

drek231 [11]

Note that 8.00 = (2.00)^3, that implies that a decay to 1/8.00 means that the Carbon-14 has passed 3 half-life. (1 to decay to 1/2, other to decay to 1/4, and other to decay to 1/8). And, three half-life is 3 * 5730 years = 17,920 years. So,<span> the answer is that the plant was alive 17,920 years.</span>
