7 0

Answer:

1 or 4 or 7

Step-by-step explanation:

The number is divisible be 15, that means it is divisible as by 5 and as by 3

(5*3=15).  The number is divisible by 5 if the last digit is 0 or 5.

In our case the last digit is 0 so the number is divisuble by 5 anyway.

The number is divisible by 3 if the sum of its digits is divisible by 3.

The sum of digits is 8+9 =17 .   17 is not divisible by 3, however 18,21 or 24 are divisible by 3

So instead ... 1 ( to get sum 18), or 4 ( to get sum 21) or 7 (to get sum 24) can be written

galben [10]

Answer: 3/10 probability

Step-by-step explanation:

We are telling the probability with tenths, so we can say that the probability of the meteoroid landing on Earth is 3/10.

If the surface area of the world is approximately 7/10, or 70 percent, water, there is approximately 3/10, or 30 percent, chance of the meteoroid hitting land.

I'm pretty sure, at least ^_^
