To find an average you add all numbers together then divide by the amount of numbers that you added. So if there are 4 numbers you would divide by 4. By going backwards you can find the answer. Multiply 5 by 4 and you get 20, which is the answer.

Which statement correctly describes the end behavior of y = 3x8 + 5x2 +2x - 1
Usimov [2.4K]
The end behavior of functions with exponents is quite simple when you realized that as x approaches infinity that the function will act as if the highest exponent term is the only one which exists...

In this case 3x^8 is the highest order term, so y approaches +oo as x approaches +oo or -oo.  Or in other words y increases without bound as x approaches ±oo

canada has a population that is about one tenth as large as the united states. if canada's population is about 32 million about
trapecia [35]
In this problem it states that one tenth or only 10% is Canada’s population to the United States. Hence with the steps we can identify the population of the United States.
<span><span>1.       </span>10 % = 32 million or 0.1 = 32 million</span>
<span><span>2.       </span>Then 32 million / 0.1 = 320, 000, 000 million</span>

Therefore there are 320, 000, 000 million living in the United States
Adding one zero. Why the zeroes? It is the result because of the power of 10 in a hundred percent population coming from the Canada’s population. Take note that 100% = 320, 000, 000 million of the USA while 10% of it is Canada so we divide it by 0.1 which is 32, 000, 000 (the power of ten)
