B.
The median increases less than the mean increases.
I basically just used guess and check for this question and ended up with a set of five numbers, which are 5,6,8,8,13
Mean: 5+6+8+8+13 divided by five is eight,so that's correct
The mode is eight so that's correct
The median is eight too so that's correct
If there are 4 friends and 1 flashlight and only two of them can pass at a time then
that will mean that has to pass 2 times per person and the last time only one
for 32 will be 31*2 + 1 = 63
in a general matter will be
T = (X-1)*2 + 1
T = 2X - 1
so for 3 friends will be (this does not take into consideration the flashlight guy)
T = 3*2 - 1 = 5 times
Ln(x) should be the answer
43% decrease and its spelled percent
