Hey there.

9 + 13 + 9 = 31
31 + 10 + 10 = 51
51 + 9 + 10 = 70
70 + 10 + 11 = 91
91 + 9 = 100

100 / 10 = 10

10 is your mean.

I hope this helps!

Mean = it's really just another word for average. You add all the values up together, and divide the sum by the number of values there are. So here :

9 + 13 + 9 + 10 + 10 + 9 + 10 + 10 + 11 + 9 = 100

And now, you count how many values there are ^ up there. There are 10 values (just count how many numbers there are) and then you have to divide 100 by 10.

100 ÷ 10 = 10

Your MEAN is : 10

The distribution of individual incomes in the United States is strongly skewed to the right. In 2013, the mean and median income

vesna_86 [32]

Answer:

The mean would be $322,343 and the median would be $196,723.

Step-by-step explanation:

Since the distribution of individual incomes is skewed to the right, it means that the distribution has a long right tail.

Drawing a distribution with this characteristic, we can see how the majority of the data falls into the left side of the graphic, meaning that a lot of people receive less income. Following this reasoning, the mean which is the amount of the data (in this case individual income) divided by the amount of people, would be the higher number, meaning that the few people who earn more money would influence in making this number higher.

Following this reasoning, the median (which is not influenced by this difference) would be the less high number.

Calculate the average speed of a complete round trip in which the outgoing 300 km is covered at 97 km/h, followed by a 1.0-h lun

gizmo_the_mogwai [7]

Answer:

Average Speed is 65 km/hr

Step-by-step explanation:

To get the average speed, first we have to calculate the time spent in the round trip .

Speed= Distance/ time

So, Time= Distance/Speed

Time Outgoing= 300km/ 97km/hr

Time Outgoing=3.0927 hr

Time lunch break =1 hr

Time return= 300km/ 58km/hr

Time Outgoing=5.1724 hr

Total= 3.0927 hr+1 hr+5.1724 hr=9.2651

To get average speed, we have to divide all the distance by the time it took al the trip.

Average Speed= Distance/ time

Average Speed= 600km/9.2651 hr= 64,76 km/hr

Average Speed=64,76 km/hr ≅ 65km/hr
