How does it suggest that the sample mean and median will compare? The display is positively skewed, so the median will be greater than the mean. The display is reasonably symmetric, so the mean and median will be close. The display is negatively skewed, so the median will be greater than the mean. The display is positively skewed, so the mean will be greater than the median. The display is negatively skewed, so the mean will be greater than the median. (b) Calculate the values of the sample mean x and median x tilde. [Hint: Σxi = 9643.] (Round your answers to two decimal places.) x = sec x tilde = sec (c) By how much could the largest time, currently 425, be increased without affecting the value of the sample median? (Enter [infinity] if there is no limit to the amount.) By how much could this value be decreased without affecting the value of the sample median? (Enter [infinity] if there is no limit to the amount.)

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.

step-by-step explanation:

answer: two angles are called supplementary if they add up to 180°. example: the two angles (140° and 40°) are supplementary because they add up to 180°.
