Answer:
360
Step-by-step explanation:
The given digits are 1,2,3,4,5,6.
So, total number of digits = 6.
We need to find the number of different ways to form four-digit numbers using the digits, without repetition.
Total ways for first place = 6
After selecting 1 digit the number of remaining digits is 5. So,
Total ways for second place = 5
Similarly,
Total ways for third place = 4
Total ways for forth place = 3
Total number of ways =
Therefore, 360 four digit numbers are possible.
Answer:
B) 0.42
Step-by-step explanation:
population density=number of people/square units
we plug in 2,100 for the first one but we don't know the second one for that we need the area which is A=π so the radius is 40 millimeters so
=1600 1600*π=5024
2,100/5024=0.417 round it up and it is 0.42
so B) 0.42 is the answer
