Answer:
Refer to the diagram in the attachment.
Step-by-step explanation:
There are two events here: the first one is the number on the cube. The second one is the outcome of the coin toss. This tree should contain two columns, one for each event.
Start with the first column. Let 
be the outcome of the number cube. There are six possible values: 
. That corresponds to six branches, one for each outcome.
Continue to the second column. Let 
be the outcome of the coin toss. No matter which number was obtained for , there would always be two possible outcomes for
Answer:
Step-by-step explanation:
If the lines were parallel the angle measruing 72 and the angle measuring 109 would add up to 180 degrees(corrosponding and theroum ,sum of angles on line)
Z is 70. That leaves y, which would be 103.
Answer:
25/4 will have to be added to "complete the square"
Step-by-step explanation:
x² - 5x - 18 = 0
x² - 5x = 18
Find the half of the coefficient of x and square it
(5/2)² = 25/4
Add 25/4 to both sides to complete the square
x² - 5x + 25/4 = 18 + 25/4
x² - 5x + 25/4 = 18(4/4) + 25/4
x² - 5x + 25/4 = 72/4 + 25/4
x² - 5x + 25/4 = (72+25)/4
x² - 5x + 25/4 = 97/4
(x - 5/2)² = 97/4
Find the square root of both sides
√(x - 5/2)² = ±√97/4
x - 5/2 = √97/2
x = √97/2 + 5/2 or x = -√97/2 + 5/2
x = 7.42443 or -2.42443
