Two numbers that add to 22 but multiply to -48 are 24 and -2.
Answer:
5.0
Step-by-step explanation:
If we call the intensity of the larger quake I2, and that of the smaller quake I1, then we want to find I2/I1.
The log of that ratio is given by ...
log(I2/I1) = log(I2) -log(I1)
= R2 -R1
= 8.2 -7.5
log(I2/I1) = 0.7
Taking antilogs, we have ...
I2/I1 = 10^0.7
I2/I1 = 5.0
The stronger quake is 5.0 times as intense as the lesser one.

Answer:
0.8 is the probability that a single detection system will detect a missile attack.
Step-by-step explanation:
We are given the following information:
We treat detection a missile attack as a success.
P(detecting a missile attack) = 80% = 0.8
Then the number of missile attack follows a binomial distribution, where
where n is the total number of observations, x is the number of success, p is the probability of success.
Now, we are given n = 1
We have to evaluate:
0.8 is the probability that a single detection system will detect a missile attack.
