The formula after making t subject of the formula is:

Step-by-step explanation:
Given formula is:

To make t the subject of the formula we have to isolate t
So,
<u>Cross-multiplying</u>

<u>Adding 4t on both sides</u>

<u>Subtracting 3q from both sides</u>

<u>Taking t common on left hand side</u>

<u>Dividing both sides by q+4</u>

The formula after making t subject of the formula is:

We have that
n----------> number of cities
the probability that the tourist will visit the cities in alphabetical order is (1/n<span>!)
P=</span>(1/n!)
n!-------------> (7*6*5*4*3*2*1)=5040
therefore
1/5040=0.000198-----------> (five decimal places)--------> 0.00020 (0.020%)
the answer is 0.00020 (0.020%)
Answer:
The second one.
Step-by-step explanation:
1. 1/2. 3+1/8 = 4/8 = 1/2
2. 1/4. 3+1/16 = 4/16 = 1/4
