Question:

The number of years Mr) since two independently evolving languages split off from acommon ancestral language is approximated by Mr) = — 5000 lnr where r is the proportion of the words from the ancestral language that are common to both languages now. a. N(0.9) = D (Round to the nearest tens place.)b. N(0.5) = I] (Round to the nearest hundreds place.) 1:. N(0.1)= I] (Round to the nearest thousands place.) d. How many years have elapsed since the split it 80% of the words of the ancestral language are common to both languages today?I] years have elapsed since the split. (Round to the nearest hundreds place.) e. If two languages split off from a common ancestral language about 2000 years ago, find r. r= I] (Round to the nearest tenth as needed.)
