now, if that value is less than 100, then the fellow is "undernourished", otherwise, is overfed.

By greater if you mean faster, then you are comparing the fractions 11/10 and 7/6. Finding a common denominator, which is thirty, we get the fractions 33/30 and 35/30. We can see that 35>33, making Song B faster.

Suppose that the number of worker-hours required to distribute new telephone books to x% of the households in a certain rural co
Ad libitum [116K]

Answer:

a) Domain = (-\infty,400)\cup (400,\infty)

b) x \in [0,100]

c) 53.03 worker hours

d) 83.33 worker hours

e) 83.33 worker hours

Step-by-step explanation:

We are given the following in the question:

W(x) = \dfrac{250x}{(400-x)}

where W(x) is the number of worker-hours required to distribute new telephone books to x% of the households in a certain rural community.

a) Domain of function.

The domain is the all the possible values of x that the function can take.

Domain = (-\infty,400)\cup (400,\infty)

b) Values of x

Since x is a percentage in reference to context, it can only take value upto 100. Also it cannot take any negative value.

So domain n reference to context will be

x \in [0,100]

c) worker-hours were required to distribute new telephone books to the first 70% of the households

W(70) = \dfrac{250(70)}{(400-70)} = 53.03

53.03 worker hours were required to distribute new telephone books to the first 70% of the households.

d) Worker hour for entire community

For entire community, x = 100

W(100) = \dfrac{250(100)}{(400-100)} = 83.33

83.33 worker hours were required to distribute new telephone books to the entire households.

e) Percentage of the households in the community for 3 worker hours

3 = \dfrac{250x}{(400-x)}\\\\1200-3x = 250x\\253x = 1200\\\\x = \dfrac{1200}{253} = 4.74\%

Thus, 4.74% of the households in the community had received new telephone books by the time 3 worker-hours had been expended.
