Answer:
13.5 mg
Step-by-step explanation:
Here given Cobalt isotope has half life of 5.3 years.
Initial amount is 50 mg.
Given time(10 years) is roughly equals to two half life.
So, after 5.3 year 25 mg of isotope will left further in next half life only around 12.5 mg remains.
Among options 13.5 mg is the best possible
The volume of the oblique prism is 16261 cubic units
<h3>How to determine the volume?</h3>
The given parameters are:
Height = 23
Base area = 707
The volume is calculated as:
V = base area * height
So, we have:
V = 707 * 23
Evaluate
V = 16261
Hence, the volume of the oblique prism is 16261 cubic units

Answer:
Option a) Has an above average price-to-earning ratio
Step-by-step explanation:
We are given the following in the question:
The price-to-earning ratio for firms in a given industry is distributed according to normal distribution.
For a particular firm the ratio x has a standard normal variable has a value,
z = 1
Formula:
Thus, the firm has an above average price-to-earning ratio as the ratio is one standard deviation above the mean.
Option a) Has an above average price-to-earning ratio
