Answer:
-First player wins:
-Neither player wins:
Step-by-step explanation:
Applying the 4 step method:
Step 1: Identify events for which probability is to be determined:
- First player wins: First coin is heads, second coin is tails (HT)
- Neither player wins: Both coins are heads or both coins are tails (HH or TT)
Step 2: Calculate total number of possible outcomes:
Four possible outcomes: HH, HT, TT, TH
Step 3: Calculate probability of each event
Since the probability of a coin coming up heads is 'p':
Step 4: Add probability of each event
-First player wins:
-Neither player wins:
60 + 0.50(x - 40) < = 270
60 + 0.50x - 20 < = 270
40 + 0.50x < = 270
0.50x < = 270 - 40
0.50x < = 230
x < = 230/0.50
x < = 460 miles
Answer:
Construct a line from A perpendicular to the x-axis, determine the distance from A to the x-axis along this perpendicular line, find a new point on the other side of the x-axis that is equidistant from the x-axis
Step-by-step explanation:
we know that
The rule of the reflection of a point across the x-axis is equal to
(x,y) -----> (x,-y)
That means ----> The reflected point will be located equidistant from the x-axis
so
Construct a line from A perpendicular to the x-axis
Determine the distance from A to the x-axis along this perpendicular line
Find a new point on the other side of the x-axis that is equidistant from the x-axis
therefore
A(-2,1) --------> A'(-2,-1)
The reflection point is A'
The distance of point A to the x-axis is equal to 1 unit
The distance from point A' to the x-axis is also 1 unit
Answer:
28 yd²
Step-by-step explanation:
find the two biggest sides
2x4
8 but there are two sides...
8*2= 16
*16*
now side panels
1x4
4 but there are two
4*2= 8
*8*
top and bottom panels
2x1
2 but there are two
2*2= 4
*4*
add them up
16 + 8 + 4= 28
