Answer:
33 2/3
Step-by-step explanation:
9x-3=300
Add 3 to both sides
9x=303
divide by 9 on both sides
x=33 2/3
Answer:
Sample space is ![\{F,PF,PPF,PPP\}](https://tex.z-dn.net/?f=%5C%7BF%2CPF%2CPPF%2CPPP%5C%7D)
Step-by-step explanation:
Number of security doors = 3
Let P denote a successful pass and F denote a failed pass.
Sample space refers to a set of all possible outcomes.
If the first attempt to pass through a door is a failure, then the outcome is F.
If the second attempt to pass through a door is a failure, then the outcome is PF.
If the third attempt to pass through a door is a failure, then the outcome is PPF.
If the fourth attempt to pass through a door is a failure, then the outcome is PPP.
Sample space is ![\{F,PF,PPF,PPP\}](https://tex.z-dn.net/?f=%5C%7BF%2CPF%2CPPF%2CPPP%5C%7D)
Answer:
![\huge\boxed{f = 5\ Hz}](https://tex.z-dn.net/?f=%5Chuge%5Cboxed%7Bf%20%3D%205%5C%20Hz%7D)
Step-by-step explanation:
<u><em>Given:</em></u>
Time period = T = 0.2 sec
<u><em>Required:</em></u>
Frequency = f = ?
<u><em>Formula:</em></u>
f = 1/T
<u><em>Solution:</em></u>
f = 1/0.2
f = 5 Hertz
Answer:
Step-by-step explanation:
|14-(6-x)| = |14-6+x| = |8+x|
|8+x| = 8+x if x > -8
|8+x| = -x-8 if x < -8
|8+x| = 0 if x= -8
