Answer:
174.50
Step-by-step explanation:
first order the numbers from least to greatest then find the middle digit. if there are two, add them together, then divide them by 2. if there's only one, that is your median.
 
        
             
        
        
        
Answer:
Step-by-step explanation:
This is a pretty basic related rates problem. I'm going to go through this just like I do in class when I'm teaching it to my students.
We see we have a snowball, which is a sphere. We are talking about the surface area of this sphere which has a formula of
 
 
In the problem we are given diameter, not radius. What we know about the relationship between a radius and a diameter is that
d = 2r so
 Now we can have the equation in terms of diameter instead of radius. Rewriting:
 Now we can have the equation in terms of diameter instead of radius. Rewriting:
 which simplifies to
 which simplifies to
 and a bit more to
 and a bit more to
 (the 4's cancel out by division). Now that is a simple equation for which we have to find the derivative with respect to time.
 (the 4's cancel out by division). Now that is a simple equation for which we have to find the derivative with respect to time.
 Now let's look at the problem and see what we are given as far as information.
 Now let's look at the problem and see what we are given as far as information.
The rate at which the surface area changes is -3.8, and we are looking for  , the rate at which the diameter is changing, when the diameter is 13. Filling in:
, the rate at which the diameter is changing, when the diameter is 13. Filling in:
 and solving for the rate at which the diameter is changing:
 and solving for the rate at which the diameter is changing:
 and divide to get
 and divide to get
 Obviously, the negative means that the diameter is decreasing.
 Obviously, the negative means that the diameter is decreasing. 
 
        
             
        
        
        
Scientific notation is used so that the order of the number is known in first glance. The value of the given number in scientific notation is given by: Option B: 
<h3>How does scientific notations work?</h3>
The number is written in the form  where we have
 where we have 
The number b shows the order, which is the most important figure for which scientific notation is used. It tells us how much order large or small a value is in powers of 10. We can for a time, ignore the value of 'a' for two comparable quantities and only compare their orders(this type of comparison is useful when difference is too big, like size of human to size of a star etc sort of comparisons).
Scientific notations have some of the profits as:
- Better readability due to compact representation
- Its value in terms of power of 10 is known, which helps in easy comparison of quantities differing by a large value.
For the given case, the number in consideration is 0.0000069 
Rewriting it in fraction form, we get:

(we used two facts: first that : 
and second that: 
Thus, the value of the given number in scientific notation is given by: Option B:
