Answer:

B = 18m

C = 19.5m

h = 9m

Step-by-step explanation:

7.5/5 = 1.5

12*1.5 = 18

13*1.5 = 19.5

6*1.5 =  9m

System of equations, special case infinitely many solutions?????
Mashcka [7]

One possible system is

1x + 3y = 4

2x + 6y = 8

Note how 2 is twice as large as 1, 6 is twice as large as 3, and 8 is twice as large as 4.

In other words, the second equation is the result of multiplying both sides of the first equation by 2.

1x+3y = 4

2*(1x+3y) = 2*4

2x+6y = 8

Effectively the two equations in bold are the same which produces the same line. The two lines overlap perfectly to intersect infinitely many times. An intersection is a solution.

Answer:

Both A and B

Step-by-step explanation:

For functions you are just trying to make sure all the x's are different.  

So let's look at A:  The x's there are all different so it is a function

Now let's look at B: The x's there are all different so it is a function.

Both A and B

Find the slope of the line <br> -2/1<br> 1/2<br> -1/2<br> 2/1
natka813 [3]

Answer:

1/2

Step-by-step explanation:

you the x and the y intercepts!

the X intercept is (4,0) and the Y intercept is (0,-2)

and in having those two intercepts, it made solving for the slope a whole lot easier!!!

heres what you do:

<u>-2 - 0  =   -2</u>

0 - 4  =   -4

and that can be simplified down to 1/2 :D

<em>i wasn't quite sure what the numbers you put in the question were, so i just looked at the picture :D hope this helps!!! </em>

Ksju [112]

Answer:

1. P(S) = 373/580

2. P(S|A) = 53/116

3. P(S|Pa) = 481/580

Step-by-step explanation:

Given

---------------------Sale ----- No Sale-----Total

Aggressive ----265 --------315 ----------580

Passive ----------481 ---------99 -----------580

Total --------------746---------414------------1160

A = aggressive approach,

Pa = passive approach,

S = sale,

N= no sale.

(a) Computing P(S)

This is calculated as the division of customers that participated in sales by total customers

Customers that participated in sales = 265 + 481 = 746

Total Customers = 1160

P(S) = 746/1160

P(S) = 373/580

b.

P(S|A) means that the probability that a sales occur given that the aggressive method was used.

To solve this, we check the cell where Sales and Aggressive intersect

The cell element = 265

Total = 580

P(S|A) = 265/580

P(S|A) = 265/580

P(S|A) = 53/116

c.

P(S|Pa) means that the probability that a sales occur given that the passive method was used.

To solve this, we check the cell where Sales and Passive intersect

The cell element = 481

Total = 580

P(S|Pa) = 481/580
