PLEASE HELP!!
Minchanka [31]

Answer:

5/48

Step-by-step explanation:

There are 12 letters in pennsylvania

P (n or a) = (number of n's and a's)/ total

There are 3 n's and 2 a's

P (n or a) = 5/12

P (Vertical symmetry) = letters with vertical symmetry/ total

Only V  I and Y have vertical symmetry  3 letters

P ( vertical symmetry) = 3/12

Multiply the probabilities together

5/12 * 3/12 = 15/144 = 5/48

qr - pr \: + qs - ps

r(q - p) + s(q - p)

(r + s)(q  - p)

2.

{x}^{2}  + y - xy - x

{x}^{2}  -  x - xy + y

x(x - 1) - y(x - 1)

3.

6xy + 6 - 9y - 4x

- 4x + 6 + 6xy - 9y

2( - 2x + 3) - 3y( - 2x + 3)

(2 - 3y)( - 2x + 3)

4.

{x}^{2}  - 2ax - 2ab + bx

x(x - 2a) - b(x - 2a)

-(x +b)(2a-x)

What is the slope of the line on the graph?<br><br><br><br> Enter your answer in the box.
alexira [117]
To find the slope,we can use the slope formula:
\frac{y1 - y2}{x1 - x2}
Where x and y are y coordinates and x coordinates respectively.

To find the answer, put any two points into the formula.

In this case, (1,5) and (0,-1) will be used:

x1 and y1 would be the x and y coordinate in the first point(1,5), while x2 and y2 would be the x and y coordinate in the first point (0,-1)

\frac{5 - ( - 1)}{ 1- 0}  \\  =  \frac{5 + 1}{1}  \\   = \frac{ 6}{1}  \\  = 6
Therefore the answer is 6.

Hope it helps!
