Answer:
a) X=0 P(0)=0.9737
X=30 P(30)=0.0263
b) Mean: 0.789
SD: 4.801
c) P(X>1)=0.072
Explanation:
<em>The question is incomplete:</em>
<em>a) Let denote X your winnings when you play once. State the probability distribution of X.</em>
<em />
<em>b) You decide to play once a minute for a total of 1050 times. Find the mean and standard deviation.</em>
<em />
<em>c) Refer to (b). Using the Central Limit Theorem, find the probability that with this amount of roulette playing, your mean winnings is at least $1 (so, you don't lose money).</em>

a) X has only two possible states: "0" and "30". The probability distribution for x is:
X=0 P(0)=37/38=0.9737
X=30 P(30)=1/38=0.0263
b) First, we calculate the mean and standard deviation of the population as:
Then, the sampling distribution has these mean and standard deviation:
c) If we use the CLT, we can approximate this binomial distribution with a normal distribution to facilitate the calculations.
To calculate the probabilities of a outcome that is equal or bigger than $1, we first calculate the z-value:
The answer for the first question is D.
Many organization adopting a societal stance to social responsibility respond to requests for donations to Little League, Girl Scouts, and youth soccer programs.
Answer: The Option "d.returning inventory that is defective or broken" is NOT an example of safeguarding inventory.
Explanation: If we analyze the statements:
a.physical devices such as two-way mirrors, cameras, and alarms - These are all tools intended for protection against possible inventory theft.
b.storing inventory in restricted areas - Restricting access only to inventory-enabled personnel is able to protect the inventory much more than if anyone can access it.
c.matching receiving documents, purchase orders, and vendor's invoice - Controlling each of the purchase documents and performing the physical count reduces the possibilities of inventory differences for losses or errors.
d.returning inventory that is defective or broken - Returning the defective inventory is a post-echo action that occurred due to the unprotection of the inventory, therefore it could not be referred to as an example of inventory protection.
Answer:
Unearned membership revenue of $9,000
Explanation:
The sales on credit during January 2017 was valued at $12,000 ($200 x 60).
In March 2017, customers paid $3,000, leaving the balance of $9,000 outstanding.
Since the season for which sales and collections were made starts March 1, 2017, when reporting the financial statements for the period ending March 31, 2017, the Membership Revenue would be $3,000 only and the balance $9,000 would be reported as Unearned Membership Revenue in the Balance Sheet with a further $9,000 reported in the Accounts Receivable to balance the records.
This shows that Unearned Membership Revenue of $9,000 is the only valid statement.
