Answer:
About 7.94 times
Step-by-step explanation:
The intensity of an earthquake can be found using the formula:
Where
I is the intensity
I_0 is intensity of magnitude 0 earthquake
M is Richter scale magnitude
For first quake, it will be:
For the second quake, it will be:
The times the intensity is more can be found by dividing both, so we have:
The first earthquake is about 7.94 times the second quake
Answer:
The probability is 0.9
Step-by-step explanation:
We start by calculating the density function
That will be;
f(x) = 1/(b-a)
b and a are the extremes
from the question,
a = 15
b = 65
So f(x)
= 1/(65-15) = 1/50 = 0.02
The probability we want to calculate is;
P( x > 20)
The termination point is 65
So the probability will be
(65-20) * 0.02
= 0.9
we are given
we will isolate x
so, firstly we will move all x terms on any one side
We will add both sides 2
now, we can subtract both sides 2x
now, we can divide both sides by 4
and we get
......Answer
That is a equation in slope intercept form.
