Firstly, let’s assume the the whole capacity the work requires is 1.

Then, let’s see how 1 man can do in 50 days: 1/5.

Further, let’s see how 1 man can do in 1 day : 1/(5×50) = 1/250.

Similarly, let’s see how 1 woman can do in 1 day: 1/(10×50) = 1/500.

Now, we have 8 men, and they can do 8*1/250 in 1 day, which is 4/125.

Besides, we have 4 women, and they can do 4×1/500 in 1 day, which is 1/125.

Therefore, all people we have can do 4/125 + 1/125 of the work in 1 day, which is 1/25.

As a result, the work takes 1/(1/25)= 25 days.

Draw a line representing the "rise" and a line representing the "run" of the line. State the slope of the line in simplest form.

m_a_m_a [10]

Answer:

Line of "rise": (0, 3) to (0, 0) ==> -3 units

Line of "run": (0, 0) to (1, 0) ==> 1 unit

Slope: rise/run ==> -3/1

Step-by-step explanation:

Slope is basically a ratio of changes in the y-value to changes in the x-value. What I mean by that is the slope shows how much the line goes up or down compared to how much the line goes left or right. In this case, the line goes right one unit for every 3 units the line goes down. Taking a look at the portion of the line in Quadrant 1 (top right quadrant), the line starts at (0, 3) and ends at (1, 0). I guess that's another way to figure out slope, too: line up the two coordinates (the leftmost one above the rightmost one), and add or subtract.

Like this:

(0, 3)

+1 -3

Since the formula for slope is rise/run (y-difference/x-difference), the slope is therefore -3/+1, or simply -3/1. (You don't include plus signs.)

See the attached picture. You'll find a tree with four branches at level 1 (each of the four sectors of the spinner). Each of these branches is divided in four sub-branches: the possible results of tossing two coins (HH, HT, TH, TT).

So, there are 16 possible outcomes (numbered below each leaf).

If you want to roll an odd number, you have to take branch 1 or 3 at first level.

Then, for each of those, you have to toss exactly one head, so you have to take HT or TH.

The good outcomes are thus 2, 3, 10 and 11, leading to a probability of 4/16=1/4=25%.
