What is the 4th term of the expansion of (1-2x)^n if the binomial coefficients are taken from the row of Pascal's triangle shown below? 1 6 15 20 15 6 1

A: -160x^3

B: -20x^3

C: 160x^3

D: 240x^4​

answer: the answer is 40.82

step-by-step explanation: 3.14 x 13(or half of 26) to the power of 2

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.
