Answer:
90minutes
Step-by-step explanation:
Let the time taken for passengers to be checked-in be t
Let the number of staff working be w;.
If the time taken for passengers to be checked-in for a flight is inversely proportional to the number of staff working then;
t = kw
when t = 30, w = 5
30 = 5k
k = 30/5
k = 6
to get t when w = 15
t = kw
t = 6(15)
t = 90minutes
Hence it will take 90minutes long
Answer:
x < -15
Step-by-step explanation:
Here is the solution:
-3x-42 > 3
Add the numbers
-3x > 45
Divide both sides of the inequation by -3 and flip the inequality sign.
x < -15
Answer:
Step-by-step explanation:
For a coin, the probability of head showing in a single toss is 
.
Its complement, the probability of not head is
This is a binomial distribution. In 
tosses, the probability of having all heads (i.e. heads) is
Let's call this value 
.
For 
coins, we determine the probability of at least 1 coin showing all heads by first finding its complement i.e. the probability of no coin showing all heads. This is also a binomial distribution.
Hello!
(Length x height x width) ÷ 3 = volume
6 x 3 x 7
18 x 7
126
126 ÷ 3 = 42
The volume is 42 ft ³.
Hope this helped!
