Step-by-step explanation:
Median age is the age that divides a population into two numerically equally sized groups - that is, half the people are younger than this age and half are older. It is a single index that summarizes the age distribution of a population.
There are a various of ways solve this expression. We can choose to do completing the square method or to use the quadratic formula. In this case, I will choose to do completing the square. We do as follows:
<span>x^2 - 7x = -13
</span><span>x^2 - 7x + 49/2= -13 + 49/2
(x - 7/2)^2= 23/2
</span>√[(x - 7/2)^2]= √(23/2)
x-7/2 = √46 / 2
x = √46 / 2 + 7/2
Hope this answers the question. Have a nice day.
So to find the answers for each of these, divide the first dog's amount mentioned by the second dog's amount mentioned. For instance, the first one would be 45 over 60, also equal to 3/4. So Bailey ate 3/4 cup for every cup fido ate. Repeat this same process with all the other questions and you can get the following answers:
Fido ate 1 1/3 cup for each cup Bailey ate.
Gunner ate 2 1/2 cups for each cup Spot ate.
Spot ate 2/5 cup for each cup Gunner ate.
Hope this helps!
