What is the mean median and mode of 99, 69, 96, 69, 78. Round to the nearest tenth if necessary
KiRa [710]
A median is the middle number of a data set.
To find it put the numbers in order.
78, 69, 69, 96, 99
Then find the middle number
78, 69, *69,* 96, 99

The median is 69

A mode is the number that appears the most in a set of numbers.
78, *69, 69,* 96, 99

The mode is 69

To find the mean or average of a set of numbers, add all the numbers together then divide by the number of numbers there are.
99+69+96+69+78 = 411
411/5 = 82.2

The mean is 82.2

Hope this helped! If you have anymore questions or don't understand, please comment on my profile or DM me. :)

Alex73 [517]
I think
A. convert the time to seconds, so all the time are 7070sec and the total course to meter.
so 31300meter
Vector = TotalCourse÷total time
V=31300/7070=4.427157m/s
convert it to km/h so 4.427157×36÷10=
15.9377km/h
B. 45÷15.9377=2.823Hour
it means that around 2 Hour 48Minutes more.
i think the teacher need to simplify it
