Answer:
7.2
Step-by-step explanation:
Mean is when you add all the numbers together and divide them by the number of values there are in total.
There are 10 numbers, so find the sum of all the numbers and divide by 10.
= 72/10 = 7.2

Step-by-step explanation:
A mathematical model refers to a mathematical function that describes natural phenomena.
Models are used to approximate natural phenomena hence they are not really exact representations of reality. Thus mathematical models are inherently imperfect and so is our understanding of natural phenomena represented by these mathematical models.
The mathematical parameters used in models to represent real processes are uncertain since they are determined from experiment or represent more than one process.
Lastly, the initial and the boundary conditions in a model may not be explicitly established.

To get the common denominator you would multiply the first term by (x-4)/(x-4) and you multiply the second term by (x+4)/(x+4):
<span> (x-4) 4 </span> + <span> x (x+4)</span>
(x-4)(x+4). (x-4)(x+4)
The next step is to distribute the 4 (x-4) and the x (x+4)
so now you have
4x-16 + x^2 + 4x
(x - 4) (x + 4)
now combine like terms and put them in order exponents
<span>x^2 + 8x - 16
</span>(x-4)(x+4)
Since x^2 + 8x - 16 is not factorable you are done. That is your answer:
<span><u>x^2 + 8x - 16</u>
</span>(x-4)(x+4)
Answer:
5 times 12 = 12 times 5
Step-by-step explanation:
You flipped the factors since they were the same. 5 times 12 = 60 when you flip the factors 12 times 5 = 60
