Answer:
1280
Step-by-step explanation:
I think it is 1280 because 20*16*8/2=1280. I am not 100% sure.
Answer:
1,215
Step-by-step explanation:
Because if you think of it it multiplies by 3x so 3x5=? 15! 15x3=? 45! 45x3=? 405! 405x=3? 1,215! 1,215x3=? 3,645! anyways, I can go on and on I hope this answer was right!

Step-by-step explanation:
All you have to do is multiply 19•14•14
If the probability that a household owns a pet is 0.55 then the probability that all households will have pets is equal to 0.0503.
Given that the probability that a household owns a pet is 0.55 and there are 5 houses on a block.
We are required to calculate the probability that all the five households will have pets.
Probability is basicallly the chance of happening an event among all the events possible. It cannot be negative.
Binomial probability distribution is basically the probability calculations but in different combinations.
In this we have to calculate the probability that all the houses will have the pets then the probability that all five households will have pets is equal to ![5C_{5}(0.55)^{5} (1-0.55)^{0}](https://tex.z-dn.net/?f=5C_%7B5%7D%280.55%29%5E%7B5%7D%20%281-0.55%29%5E%7B0%7D)
=1(0.0503)![(0.45)^{0}](https://tex.z-dn.net/?f=%280.45%29%5E%7B0%7D)
=1*0.0503*1
=0.0503
Hence the probability that all the five households will have pets is equal to 0.0503.

Answer: (30m-9n)/270
First we start with m/9-n/30.
We multiply the denominators to get 270.
Then we multiply the numerators by the original denominators to get (30m-9n).
To check, we can use m=2, and n=4
2/9-4/30=4/45
(30*2-9*4)/270=24/270=4/45
