18
Step-by-step explanation:
sum of ratio=5+3+4=12
Answer:
True
Step-by-step explanation:
When two events are disjoints then both events does not occur at the same time.
The intersection of both events is 0
Tossing a coin and getting a tail or head are the two disjoint events
To find the number of outcomes of disjoint sets, we add the number of each event like we add the number of outcomes of getting head and tail .
So, its true
Answer:
x=4+√73 or x=4−√73
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
x^2−8x−48=9
Step 2: Add 48 to both sides.
x^2−8x−48+48=9+48
x^2−8x=57
Step 3: The coefficient of -8x is -8. Let b=-8. Then we need to add (b/2)^2=16 to both sides to complete the square.
Add 16 to both sides.
x^2−8x+16=57+16
x^2−8x+16=73
Step 4: Factor left side.
(x−4)^2=73
Step 5: Take the square root.
x−4=±√73
Step 6: Add 4 to both sides.
x−4+4=4±√73
x=4±√73
x=4+√73 or x=4−√73
Answer:
x=4+√73 or x=4−√73
