4 Tranquil Company bought a crane for $100,000 on January 1, 2019. Additional ordinary and necessary costs to install the crane for service include: $4000 sales tax and a $1000 delivery charge. The crane has an estimated useful life of 10 years and a salvage value of $5,000. What entry would Tranquil make to record one year’s depreciation expense on December31, 2019 using a. the straight line b. the double declining depreciation methods? c. What entry would Tranquil make if it sold the crane at the end of 2019 for $89,000 and used the straight-line method of depreciation? D what entry would Tranquil make if it sold the crane at the end 0f 2019 for 89,000 and used the double-decling balance method of depreciation?

Consider tossing a coin and rolling a four-sided die (with the numbers 1 through 4 printed on the sides).
(a) Describe the sample space.
(b) Whatistheprobabilityofrollingaheadsandanevennumber?
(c) What are the odds of rolling a heads and an even number?
(d) What is the probability of rolling a heads?
(e) What are the odds against rolling a heads?
Determine whether or not the following statements are correct or incorrect and explain why (Be thorough and clear in your explanation!):
(a) A person says “the odds of rolling a 1 on a standard six-sided die is 1/6.”
(b) In the past five seasons,cross town football riva ls the Quaker sand the Comet shave played
each other with the Comets winning twice and the Quakers winning three times. Someone
says “the odds in favor of the Quakers winning are 3:5.”
(c) If the odds in favor of an event occurring are A to B, then the probability of the event
occurring is A/(A+B).
(d) An event with probability 75% means that the event is three times more likely to occur than
not occur.

Please ensure that you include your name and student number on your submission. Your submission must be created using Microsoft Word, Google Docs, or LaTeX.
Translate the following English expressions into logical statements. You must explicitly state what the atomic propositions are (e.g., "Let p be proposition ...") and then show their logical relation.
If it is red then it is not blue and it is not green.
It is white but it is also red and green and blue.
It is black if and only if it is not red, green, or blue.
Determine if the following expressions are tautologies, contradictions, or contingencies by using only truth tables. Show all your work and do not skip any steps (i.e., ensure you that you include a new column for every single operation and that you state at the end whether each expression is a tautology, contingency, or contradiction).
a. ¬(?∧(¬?∨(?→?)))
b. (? ∨(? ↔(¬?∧ (? ∨?))))
c. (? ∧¬(? ∧(? ∨(? ↔?))))d. ¬(?∨¬(?→(?∧?)))
Determine if the following expressions are tautologies, contradictions, or contingencies by using only the logical equivalences. Show all your work and do not skip any steps (i.e., ensure you that you include the name of each equivalence used (excluding commutativity and associativity) and that you state at the end whether each expression is a tautology, contingency, or contradiction).
a. (? ∧(? →¬?))b. (¬?→(?∨?))c. (? ↔(?∨ ¬?))d. (¬? ∨(?∧?))
Using only the and the operators, find a logical expression that is equivalent to (? → (? ∧ p)) → (? ∨ p). For this question, you do not need to specify "how" you found the equivalent expression because you will show both techniques in questions 5 and 6 below.
Prove that the expression you found for question 4 above is equivalent to the expression (? → (? ∧ p)) → (? ∨ p) by using only truth tables. Show all your work and do not skip any steps (i.e., ensure that you include a new column for every single operation).
Prove that the expression you found for question 4 above is equivalent to the expression (? → (? ∧ p)) → (? ∨ p) by using only the logical equivalences. Show all your work and do not skip any steps.
