Which of the following are feasible equations of a least squares regression line for number of dollars left in a retirement annuity account, that pays no interest and fixed annual withdrawals, in each of its first ten years if it was entirely funded by a single deposit? a. y ˆ =269,000+8300x.
b. y ˆ =69,000−8300x.
c. y ˆ =−269,000−8300x.
d. y ˆ =269,000−8300x.
e. y ˆ =0−8300x.

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)

sorry can't
