the ages of several trees in a park are shown below:

2 years, 28 years, 2 years, 20 years, 22 years

what is the mean age of these trees?

5.6 years
12 years
14.8 years
26 years

The "mean" is just the normal arithmetic average that you are most likely already familiar with.

mean=(sum of elements)/(number of elements)

In this case:

mean=(2+28+2+20+22)/5

mean=74/5

mean=14.8

So the mean or average age of the trees is 14.8 years.

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
