The Johnsons Change Their Life Insurance Coverage Harry and Belinda Johnson spend $20 per month on life insurance in the form of a premium on a $10,000, paid-at-65 cash-value policy on Harry that his parents bought for him years ago. Belinda has a group term i-surance policy from her employer with a face amount of $200,000. By choosing a group life insurance plan from his menu of employee benefits, Harry now has $100,000 of group term life insurance. Harry and Belinda have decided that, because they have no children, they could reduce their life insurance needs by protecting one another's income for only four years, assuming the survivor would be able to fend for himself or herself after that time. They also realize that their savings fund is so low that it would have no bearing on their life insurance needs. Harry and Belinda are basing their calculations on a projected 4 percent rate of return after taxes and inflation. They also estimate the following expenses: $15,000 for final expenses, $20,000 for readjustment expenses,

and $5,000 for repayment of short-term debts.

Requirement:

(a) Should the $3,000 interest earnings from Harry's trust fund be included in his annual income for the purposes of calculating the likely dollar loss if he were to die? (See the discussions about the Johnsons in Chapter 1 beginning on page 34.) Explain your response.

(b) Based on your response to the previous question, how much more life insurance does Harry need? Use the Run the Numbers worksheet on page 366 to arrive at your answer.

(c) Repeat the calculations to arrive at the additional life insurance needed on Belinda's life.

(d) How might the Johnsons most economically meet any additional life insurance needs you have determined they may have?

e) In addition to their life insurance planning, how might the Johnsons begin to prepare for their retirement years?

Many problems in materials science and applied physics depend on the phenomenon of percolation, the question of when there will be a connected path of some kind through a material. A simple way to figure out the connected path is to write a recursive function check_path(i, j ,a) , where i is a row index. j is a column index. and a is a 2D array, with the following properties: a if i is in the bottom row of the matrix 0 return True if a[i, j ]==1 , otherwise False - otherwise if there is no path going downward from i, j (i.e. the cells immediately below and below to the left and right are all zero), return False - otherwise return True if a[ i, j ]==1 and any of the paths going downward from i,j are connected to the bottom (i.e. call check_path( ) recursively) 0 Then write perc_path which returns True if check _path( ) is true for any of the cells equal to 1 in the first row of the array. 0 Write a function rand_bin_array(n, prob) to fill a n-byn square array randomly with 15 with probability prob . 0 Find the 2D percolation threshold by calculating the probability (proportion of random matrices where perc_Path() returns True) for 500 random arrays each for probabilities in numpy . arange ( o . 25 , o . 6 , 0.025) ; draw a plot using matplotlib . pyplot of the results. \f4.
