Answer:
405 Problems
Step-by-step explanation:
- One student in class has 15 problems.
- There are 27 students in the class.
Let's <u>multiply</u> 15 by 27.

<em>In all, there would be 405 problems assigned to the whole class.</em>
 
        
             
        
        
        
The correct answer would be D, the median 86.5.
In this set of data most of the values are in the 80's or 90's. There is only 1 number that is outside of this range, that is the value 0. It is an outlier. 
When we have an outlier, the median generally gives us the better measure of central tendency.
        
             
        
        
        
Answer:
We can use the sample about 42 days.
Step-by-step explanation:
Decay Equation:



Integrating both sides


When t=0, N= = initial amount

130 days is the half-life of the given radioactive element.
For half life,

,   days.
 days.
we plug all values in equation (1)






We need to find the time when the sample remains 80% of its original.
 







We can use the sample about 42 days.
