<span>P and S waves travel at known velocities through the Earth. S waves are slower than P waves by a known amount. As the P and S waves travel out from an earthquake the P waves get progressively farther ahead of the S waves. Therefore, the farther a seismic recording station is from the earthquake epicenter the greater will be the difference in time of arrival between the P and S wave. The distance of a seismic station from an earthquake is easily determined from the S-P interval, the time difference between the time of arrival of the first P wave and the first S wave. </span>

In her end-of-year exams, Jennie scored the following: Science 34%, English 90%, History 87%, Math 34%, and Geography 55%. What
vaieri [72.5K]

Answer:

The mean was 60%.

Explanation:

The mean is the average of your numbers. To calculate the mean you would have to add all the numbers together. Then, you’d divide your total amount by how many numbers you had to add together. For this example, you would add 34+90+87+34+55. This gives you a total of 300. Since you had 5 initial numbers, you would divide 300 by 5. You will come up with a final number of 60 which is your mean.
