Answer:
The first earthquake is 1.9 times greater than the second
Step-by-step explanation:
We need to substract
M1 and M2
M1 - M2 = ㏒(x1/c) - ㏒(x2/c)
by properties of the logarithm
= log(x1) - log(c) - (log(x2) - log(c))
= log(x1) - log(x2)
But, we know that x1 = 80*x2
So,
= log(80) + log(x2) - log(x2)
= 1.903

Answer:
Since n(1-p) < 10, it is not suitable to use a normal distribution.
Step-by-step explanation:
Suitability of the normal distribution:
In a binomial distribution with parameters n and p, the normal approximation is suitable is:
np >= 10
n(1-p) >= 10
In this question, we have that:
n = 17, p = 0.8. So
np = 17*0.8 = 13.6 -> Ok
n(1-p) = 17*0.2 = 3.4 -> No
So, since n(1-p) < 10, it is not suitable to use a normal distribution.
Answer:
3,8
Step-by-step explanation:
you can use the app photo math. just take a picture and you will get your answer
Those are two lines and the solutions are the points where the two line intersect.
*To graph the first line see if x=0 then y is...
5•0-4y=8; -4y=8; y=8/-4=-2 so this line intersects y-axis at y= -2
Also if y=0 then x is ...
5x-4•0=8; x=8/5
*Same for the other line, the graph intersections with the axis are at x=4 and y=-2
So the point of intersection is y=-2
