A) the null hypothesis is incorrectly accepted when it is false
7 goes into 63 9 times so 6/7 you would take away one 9 so it would be 6 times 9 which is equal to 54
Answer: 54 students
If we will roll a fair die then the outcomes wil be 1,2,3,4,5,6.
Hence, the total number of events= 6
3,4,5 and 6 are greater than 2.
So, there's 4 events which are greater than 2.
Now the formula to find the probability is:
probability=
=
=
So, the probability of getting greater than a 2 is 2/3.
Correct me if I’m wrong but I believe it is 11
For this problem, it is best to draw a plane showing the positive and negative, in x and y axes.
Since it is given that the coordinates of the epicenter is at (0,0), thus it is at the center of the plane.
In order to find the outside boundary of the earthquake, the center-radius equation can be used as follows:
[(x-h)^2] - [(y-k)^2] = r^2
where, (h,k) is the coordinates of the center, which is (0,0), and r is the radius which is equal to 52.
Substituting these values into the standard center-radius equation,
x^2 - y^2 = 52^2
The answer is,
x^2 - y^2 = 2704
