Twenty people get into an elevator in a hotel with seven floors, and all of them get off at some point. How many different possi

bilities exist for how the people could get off the elevator? (you can treat the people as indistinguishable for this problem, i.e., for example, if two people get off on the 4th floor, we don’t care which two people they are.)

Katarina [22]

Answer:

5/6

Step-by-step explanation:

The sides numbered 1,2,5 are green and 2,4,6 are even  

We cannot count the 2 twice, so there are 5 unique possibilities of getting either a green or an even

There are 6 total possibilities when rolling the die  1,2,3,4,5,6

P (green or even) = green or even/ total

                             = 5/6

Y= 4/5 x-7 what are the y and x intercepts?
solmaris [256]

The x intercept is (8.75, 0) and y - intercept is (0, -7)

<em><u>Solution:</u></em>

Given that we have to find the x and y intercepts

Given equation is:

y = \frac{4}{5}x - 7

The x intercept is the point where the line crosses the x axis

The y intercept is the point where the line crosses the y axis

<em><u>Finding x - intercept:</u></em>

To find the x-intercept of a given equation, plug in 0 for 'y' and solve for 'x'

Substitute y = 0 in given equation

0 = \frac{4}{5}x - 7\\\\\frac{4x}{5} = 7\\\\4x = 35\\\\x = \frac{35}{4} = 8.75

Thus x intercept is (8.75, 0)

<em><u>Finding y - intercept:</u></em>

To find the y-intercept, plug 0 in for 'x' and solve for 'y'

Substitute x = 0 in given equation

y = \frac{4}{5} \times 0 - 7\\\\y = 0 - 7\\\\y = -7

Thus y - intercept is (0, -7)
