Question:
You flip a fair coin
; What is P(heads)? If necessary, round your answer to 2 decimal places
Answer:

Step-by-step explanation:
Given:
A fair coin
Required
Determine 
A coin has two faces (Head (1) and Tail (1) )
i.e. 1 head and 1 tail
Both of which have equal probability, which is calculated as follows:



Hence:

Answer:
y = - 4x + 11
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
x - 4y = 12 ( subtract x from both sides )
- 4y = - x + 12 ( divide terms by - 4 )
y =
x - 3 ← in slope- intercept form
with slope m = 
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= - 4 , then
y = - 4x + c ← is the partial equation
To find c substitute 2, 3 ) into the partial equation
3 = - 8 + c ⇒ c = 3 + 8 = 11
y = - 4x + 11 ← equation of perpendicular line
