Let f(x) = log2(4x + 8x ln 2). For all values of a for which the function is defined, what is the instantaneous rate of change at x = a? A. 1/a
B. 1/a(ln2)
C. 1/2a(ln2)
D. 1/4a(1+2ln2)

answer: median

step-by-step explanation:

the median is the middle value when a data set is ordered from least to greatest

the radius is 2 times the diameter.

step-by-step explanation:

answer: 12   they all have at least 28 days

step-by-step explanation: haha

0 and 5 minutes

step-by-step explanation:

given that one morning eight buses arrive late by the number of minutes given below:

0 8 2 6 9 2 0 7 8

write these in ascending order

0   0 2 6 7 8 8 9

in the afternoon two more buses arrive at the bus stop say by x and y minutes late.

total number of buses = 10

median = average of 4th and 5th after arranging in ascending order

since 4th entry is 6, the values of x and y should be below 6

also given 0 is the mode so either x or y or both should be 0 because then only 0 gets the maximum frequency and hence mode

thus we have

0 0 0 2 6 7 8 8 9 and another unknown entry which is below 6.

since median is 3.5, we have the unknown entry to be 5 only because then only median =( 2+5)/2

thus the after noon buses were late by 0 and 5 minutes.
