Jim is a 60-year-old Anglo male in reasonably good health. He wants to take out a $50,000 term (i.e., straight death benefit) life insurance policy until he is 65. The policy will expire on his 65th birthday. The probability of death in a given year is provided.

Jim is applying to Big Rock Insurance Company for his term insurance policy.

(a)

What is the probability that Jim will die in his 60th year? (Enter a number. Enter your answer to five decimal places.)


Using this probability and the $50,000 death benefit, what is the expected cost to Big Rock Insurance (in dollars)? (Enter a number. Round your answer to two decimal places.)
$  

(b)

What is the expected cost to Big Rock Insurance for years 61, 62, 63, and 64 (in dollars)? (For each answer, enter a number. Round your answers to two decimal places.)
year 61 $  
year 62 $  
year 63 $  
year 64 $  

What would be the total expected cost to Big Rock Insurance over the years 60 through 64 (in dollars)? (Enter a number. Round your answer to two decimal places.)
$  

(c)

If Big Rock Insurance wants to make a profit of $700 above the expected total cost paid out for Jim's death, how much should it charge for the policy (in dollars)? (Enter a number. Round your answer to two decimal places.)
$  

(d)

If Big Rock Insurance Company charges $5000 for the policy, how much profit does the company expect to make (in dollars)? (Enter a number. Round your answer to two decimal places.)

A method used by the Environmental Protection Agency (EPA) for determining the concentration of ozone in air is to pass the air sample through a "bubbler" containing sodium iodide, which removes the ozone according to the following equation: O3(g)+2NaI(aq)+H2O(l)→O2(g)+I2(s)+2NaOH(aq)

Part A) How many moles of sodium iodide are needed to remove 5.95×10⁻⁶ mol O3?

Part B) How many grams of sodium iodide are needed to remove 2.1 mg of O3?

Consider the perfectly competitive market for canoes. Suppose the market demand for canoes is described by: Q d = 200 − 2 P and the market supply of canoes is described by: Q s = 2 P.

1. Suppose there is currently a price floor of $70 in place in the market for canoes. Consumer surplus under this price floor is (A) $900 (B) $4,900 (C) $2,500 (D) $1,800 .
2. Suppose the government removes the price floor, consumer surplus will (A) decrease by $1600 (B) increase by $1100 (C) increase by $1600 (D) increase by $3200

T or F with concise Explaination

Constrained price-bottom government policies lead to excessive demand, which is more inefficient than market discipline ( )
Those who have the will and ability to pay the price get scarce resources in the market economy.()
A decrease in supply will cause the biggest price increase when demand is very inelastic. ( )
If the government removes taxes on goods, both the price paid by the buyer and the price received by the seller will be lowered." ()
For an inelastic demand curve, the total return moves in the same direction as the price ().

DNA polymerase III builds new DNA strands in the 5' to 3' direction...always adding the new nucleotide to the 3' end of the existing strand. As it adds new nucleotides, it proofreads its work. If a mistake is detected, DNA polymerase will act as an exonuclease and excise the incorrect nucleotide. A. What supplies the energy needed to add the new nucleotide to the existing chain? B. Please explain why evolution has favored 5’ to 3’ polymerases, as opposed to 3’ to 5’ ones (hint...what happens if DNA Polymerase removes a nucleotide?).

2. A moth census on Wooded Island counted 100 black (BB) moths, 40 gray (Bb) and 60 white (bb) moths. What are the genotypic frequencies? What are the allelic frequencies? Is the population in Hardy-Weinberg equilibrium?

Basic Linked List exercises

a. Suppose x is a linked-list node and not the last node on the list.

What is the effect of the following code fragment?

x.next = x.next.next

b. Singly Linked List has two private instance variables first and last as that point to the first and the last nodes in the list, respectively. Write a fragment of code that removes the last node in a linked list whose first node is first. Is there any advantage of keeping the last pointer in a linked list implementation? Explain.

C++ PROGRAM

Code a generic (with templates) Queue structure (linear Data structure with FIFO functionality) and create a test to validate its functionality. The data consists of persons with the attributes of name, last name, age, height and weight.

- Remembrer that,

Their structure consists of:

• Head: Pointer to the first element of the queue
• Tail: Pointer to the last element of the queue

And the following operations:

• Pop: Removes the element at the head
• Top: Returns the current element at the head
• Push: Adds a new element at the tail
• isEmpty: Determine if there are any elements in the queue

Assume that x has a normal distribution with the specified mean and standard deviation. Find the indicated probability. (Enter a number. Round your answer to four decimal places.)

μ = 18; σ = 3.6
