The airline industry defines an on-time flight as one that arrives within 15 minutes of its scheduled time. The following table shows the number of on-time and late flights leaving New York and arriving in Miami between November 1 and December 31, 2018, by airlines: Airlines On-Time Late Total United 254 72 326 Delta 292 65 357 American 235 58 683 Total 781 195 a. What is the probability that a randomly selected flight was Delta and was late? b. What is the probability that a randomly selected flight was United or was on-time? c. Given the flight was late, what is the probability that it was from American? d. Given the flight was from Delta, what is the probability that it was late? e. Construct a probability tree for these probabilities.
Answers
a) The probability is $\frac{65}{357}$.
b) The probability is $\frac{781}{1000}$.
c) The probability is $\frac{58}{195}$.
d) The probability is $\frac{65}{357}$.
e) We can construct a probability tree for these probabilities. Below is the probability tree:probability tree for airlines. Therefore, the above figure is the probability tree for airlines.
The probability that a randomly selected flight was Delta and was late is $\frac{65}{357}$.Therefore, the probability is $\frac{65}{357}$.
The probability that a randomly selected flight was United or was on-time is $\frac{781}{1000}$.Therefore, the probability is $\frac{781}{1000}$.
Given the flight was late, the probability that it was from American is $\frac{58}{195}$.Therefore, the probability is $\frac{58}{195}$.
Given the flight was from Delta, the probability that it was late is $\frac{65}{357}$.Therefore, the probability is $\frac{65}{357}$.

- Step-by-step explanation:
⇒minimum payment is 2% of her balance or 10 bucks...whichever is greater...
her balance is 360
2% of 360 =
0.02(360) = 7.20
$ 10 is greater then 7.20 so ur answer is $ 10
pls mark as brainlesttttt
Answer:
Her minimum payment would be $10.
Step-by-step explanation:
To find this, first find 2% of her statement. We can do this by multiplying the amount by the percentage.
$360 * 2% = $7.20
Now, since this is less than the given minimum, she pays the $10 minimum.

Answer:
- X = 9
Step-by-step explanation:
In this question we have provided an equation that is 10+X/3 =13. And we're asked to find the value ofX .
Solution:-
Step 1: Multiplying with 3 on both sides :
Now by using distributive property multiplying 3 with 10 as well as X/3 :
On calculating further , We get :
Step 2: Subtracting with 30 on both sides :
On calculating further , We get :
- Henceforth,value ofX is9.
Verifying:-
Now we are checking whether our answer is correct or wrong by substituting values of x in given equation . So ,
- 10 + X/3 = 13
- 10 + 9/3 = 13
- 10 + 3 = 13
- 13 = 13
- L.H.S = R.H.S
- Hence , Verified .
Therefore,our value for x is correct.

The only batch of paint that will create the same colors as the first batch is Batch 5. Therefore, the correct answer is D. Batch 5
The first batch of paint has the following proportions of blue, white, and yellow:
Blue: 2 parts
White: 1.5 parts
Yellow: 1 part
In order for another batch of paint to create the same colors, it must have the same proportions of blue, white, and yellow.
Batch 2:
Blue: 5 parts
White: 7 parts
Yellow: 3.5 parts
The proportions of blue, white, and yellow in Batch 2 are not the same as the proportions in the first batch, so Batch 2 will not create the same colors.
Batch 3:
Blue: 2.5 parts
White: 3.5 parts
Yellow: 5.5 parts
The proportions of blue, white, and yellow in Batch 3 are also not the same as the proportions in the first batch, so Batch 3 will not create the same colors.
Batch 4:
Blue: 4.5 parts
White: 32 parts
Yellow: 5 parts
The proportions of blue, white, and yellow in Batch 4 are not the same as the proportions in the first batch, so Batch 4 will not create the same colors.
Batch 5:
Blue: 4 parts
White: 3 parts
Yellow: 2 parts
The proportions of blue, white, and yellow in Batch 5 are the same as the proportions in the first batch, so Batch 5 will create the same colors.
Batch 6:
Blue: 432 parts
White: 1.5 parts
Yellow: 34 parts
The proportions of blue, white, and yellow in Batch 6 are not the same as the proportions in the first batch, so Batch 6 will not create the same colors.

Answer:
D. Batch 5.
Step-by-step explanation:
The batch should have the same proportion of blue to white to yellow.
In Batch 1, there are two parts of blue, 1.5 parts of white, and 1 part of yellow.
In Batch 5, there are four parts of blue, 3 parts of white, and 2 parts of yellow.
4 / 2 = 2
3 / 2 = 1.5
2 / 2 = 1
Since the proportions are equal to those found in Batch 1, D. Batch 5 will create the same colors as the first batch.
Hope this helps!
