Answer:

Find how many shaded areas there are to non shaded areas. You can use division to simplify the fraction to get your answer.

Step-by-step explanation: By dividing the fraction, you are splitting the fraction by however much you need in order to get your answer. Ex: 6/10 divided by two would be 3/5

5. Write the equation of the line represented by the following graph (2 points):
Tcecarenko [31]

Answer:

y=2/3x-2

Step-by-step explanation:

We can first find the y-intercept of the graph.

The y-intercept is the value of y when x is 0.

So, based on the graph, we can see that the y-intercept is at (0, -2).

Now, we need to find another point in order to find the slope of the line.

Another point would be (3,0).

This is also the x-intercept.

We can put these points into the formula for slope to find the slope of the given line.

The formula for slope is: y1-y2/x1-x2

In the formula:

y1 is the y coordinate of the first point

y2 is the y coordinate of the second point

x1 is the x coordinate of the first point

x2 is the x coordinate of the second point

We can plug our points in.

-2-0/0-3

Simplify.

-2/-3

2/3

The slope is 2/3.

Put it into an equation.

We can use the form y=mx+b

This is where m is the slope and b is the y-intercept.

We can put our corresponding values in.

The final equation would therefore be: y=2/3x-2.

In how many ways can 8 people be seated in a row if (a) there are no restrictions on the seating arrangement? (b) persons A and
aleksklad [387]

Answer:

a ) P(8)   =  40320  

b ) Pt(7) =  10080

c ) P(t)   =  48

d )  P(4)  =  24

e ) P(4)  =  24

Step-by-step explanation:

a) Without restrictions  8 persons can seat according to

P(8)   =  8 !          P(8)   = 8*7*6*5*4*3*2*1

P(8)   =  40320

b) Two people must sit next to each other

Let   A  and   B are a unit in the group

Then we have 7 elements

P₁(7)   =  7 !           P₁(7)   =  7*6*5*4*3*2*1

P₁(7)  = 5040

Now this number is for arrangement  A  B   we should add the same number now with  B  A

Then  P₂(7)  = 5040  and

Pt(7) =  10080

c)  There are 4 men and 4 women that can not sit next to each other

Let   A B C  and D      stands for men   and  1  2  3  and  4  women

A 1 B 2 C 3 D 4

This kind of arrangement is what we are loking for

If we change men and women are still we have

P₁(4)   =  4!               P₁(4)  =  4*3*2*1

P₁(4) = 24

Now we dont move men but women

P₂(4) = 24

In this case P(t)   =  24+24

P(t)   =  48

d) If five men is a group we have only 4 elements

P(4)  =  4!         P(4)  = 4*3*2*1

P(4)  =  24

e) If we have four couples we only have four elements

P(4)  =  24
