Me!
a climatologist wants to determine the thickness of a glacier with a surface area of about 2 km². he selected 10 locations at random on the glacier and then measured the thickness of the glacier, in meters, at each location. 41, 38, 36, 29, 34, 44, 46, 43, 35, 40 what is the estimated median thickness of the entire glacier?

Median=39m

Step-by-step explanation:

It is given that the data set is in the form of the 10 locations on the glacier, so these are:

41, 38, 36, 29, 34, 44, 46, 43, 35, 40

In order to find the estimated median thickness of the entire glacier, we need to arrange the given data set in ascending order.Thus,

29, 34, 35, 36, 38, 40, 41, 43, 44, 46

Therefore, the median is:

Thus, the estimated median thickness of the entire glacier is 39m.

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
