Answer: Divide both sides by the numeric factor on the left side, then solve.
Exact Form: x= −83/2
Answer:
P (She selects the route of four specific capitals) = 
D. No,it is not practical to list all of the different possible routes because the number of possible permutations is very large.
Step-by-step explanation:
Let's start assuming that each route is equally likely to be chosen.
Assuming this, we can calculate P(A) where the event A is ''She selects the route of four specific capitals'' doing the following :
P(A) = Favourable cases in which the route of four specific capitals is selected / Total number of ways in 4 of 42 states
The favourable cases in which the route of four specific capitals is selected is equal to 1 .
For the denominator we need the permutation number of 4 in 42.
The permutation number is defined as :


The probability of event A is : 
Finally for the other question : The option D is the correct because the number of possible permutations is 2686320 and is very large to be listed.
Answer: 1/24
Step-by-step explanation:
you need to use kcf ( keep the first fraction change division into multiplication and flip the other fraction)
turn 12 into 12/1 and then just divide.
1/2 x 1/12
= 1/24
9/63 = 1/7 = 13/x
