The answer is D. It does not satisfy the second equation because 0 is not greater than 1.
D = r• t
reverses the equation so that D and r are on the same side
d/r = t

It is convenient to follow directions. Create a chart with activities as column headings. Since the data is divided according to gender, you would put gender on the row headings. Fill in the given numbers (black), and make the totals come out (blue).
The numbers in the row total column are exactly that: the total of the numbers in the row. (A spreadsheet can do the actual addition or subtraction for you.)
Answer:
(2) (100, 300)
Step-by-step explanation:
One wave can be divided on 4 parts, as show on the picture.
Since a length of one whole wave equals 400, a length of each part is
nanometers.
The height of the wave is decreasing on the second and on the third part, hence over the interval (100, 300).
