Answer:
13
Step-by-step explanation:
D=(-2-10)2 + (4-(-1))2
=(-12)2 + (5)2
=144 + 25
=169 then put under radical
then the answer is 13
I’m gonna say 80? This may be wrong though.
Answer:
120 different ways
Step-by-step explanation:
For the first shopping mall being visited, the candidate has 5 options
Then, for the second mall being visited, there is only 4 options, as one mall was already visited.
Following this logic, there is 3 options for the third mall, 2 options for the fourth mall and 1 option for the last mall.
So the total number of ways that the visits can be scheduled is the product of all these options:
5*4*3*2*1 = 120 different ways
