Answer:
71.1
Step-by-step explanation:
correct answer is 5, because f(-5) / g(-5) = -30/-6 = 5
80
8 x 10
2 x 4 x 5 x 2
2 x 2 x 2 x 2 x 5 <===
This means that everybody answered the same number of items. This means that every data value is equal to the mean. This outcome permits us to say that the sample standard deviation of a data set is zero if and only if all of its values are same or identical.
Answer: One 8-cm pipe (Its is greater than the total area of of two 4-cm pipes)
Step-by-step explanation:
The area of a circle can be calculate with this formula:

Where "r" is the radius of the circle.
We need to calculate the area of 8-cm pipe. In this case:

Then, substituting the radius into the formula, we get:

Now we must calculate the area of the two 4-cm pipes.
Since they are two pipes, the formula is:
In this case:
Then, substituting into the formula, we get:

Therefore, since the area of one 8-cm pipe is greater than the total area of of two 4-cm pipes, we conclude that the pipe configuration that can deliver more water to residents is:
One 8-cm pipe
