True because the mode is the number that repeats the most.
You would have the 10 on the top and then the 90 on the bottom and then you times the 90 x 0 that will = 900 so then you subtract.
Step-by-step explanation:
the median is the value, where half of the other values is smaller (or equal), and the other half bigger (or equal).
with an even number of data points that is not directly possible to find.
in this case the 2 middle values are taken and their mean value is the median.
in our case, the 2 middle values are 12 and 14.
their mean value is
(12+14)/2 = 26/2 = 13
so,
13 is the median (even though if is not a data point itself).
It will be a square with the dimensions of the a diagonal of any of the faces...
Which is just 2x^2
Letter d is the correct answer
