For each number,there is a 16 probability of rolling it (so 16 for the 1 and also 16 for the 4)
Answer:
the answer is 15
Step-by-step explanation:
density= total population/surface area
density= 375/5^2
density=375/25=15
Factor this by grouping. Group the first two terms together and then the second 2 terms together. The idea here is that, after grouping, what you can pull out in both groups is the same. Like this:
Now work on finding a common thing between the 2 groups:
See, what you have in common there now is the (x-9) that you can factor out:
And that is factored completely.
