Please help!! I need to turn it in soon! :) You find a fossil and want to determine its age using radiometric dating. You know
that Element X decays into calcium with a half-life of 1600 years. If you determine
that the fossil contains 3000 particles of element X, and 3000 particles of calcium,
how old is the fossil? Briefly explain your thinking.

-3.5 is the distance.

i've had this question so choose the one in the absolute value sign.

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.
