Answer:
see below
Step-by-step explanation:
Part A
the probability that a randomly chosen flight arrives on time = number of flights that arrive on time/ total number of flights
Part B
The same as part A but applied for each carrier and then comparing who has the closest number to 1
Part C
total number of flights that arrives on time in PHL/ total number of flights that are on time for all airports
Part D
look for the carrier Hawaiian Airlines (HA) first and then number of flights that arrives on time for HA/ total number of flights HA has
Part E
look for OO and WN in table
add up all flights made ( all airports) for OO and WN
add up all flights on time for OO and WN
divide flights on time by all flights made
Hope this will help you. :)
Sorry, but this question isn't clear can you restate what you mean
Answer:
c = 121
Step-by-step explanation:
Given
t² - 22t
To complete the square
add ( half the coefficient of the t- term )² to t² - 22t
= t² + 2(- 11)t + (- 11)²
= t² - 22t + 121
with c = 121
Thus
t² - 22t + 121 = (t - 11)²
Both the numerator and denominator are divisible by 4, meaning that when they are both divided by this number they wll be in their simplest form.
e.g. 8/4=2 and 20/4=5
Therefore the simplest form is 2/5
Answer:
x ∈ (- 9/2; 1/2), it can also be written as -9/2 <x< 1/2
Step-by-step explanation:
We have absolute value, so we will have2 inequalities.
2x + 4 < 5 and -(2x +4)< 5
2x < 1 -2x - 4 < 5
x < 1/2 -2x < 9
or x > -9/2
(-∞; 1/2) or (- 9/2; ∞)
(-∞; 1/2) ∩ (- 9/2; ∞) = (- 9/2; 1/2)
The answer is x ∈ (- 9/2; 1/2), it can also be written as -9/2 <x< 1/2.
