Azookeeper predicted the weight of a new baby elephant to be 239 lb when it was born the elephant actually waited 271 pounds at birth what was the percent error of the zookeeper's prediction a) 13.39% b) 32% c) 11.81% d) 88.19%

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
