Answer:
1. 10s
2. Slower than normal
Explanation:
1. To calculate the normal time, we first take the average of Charlene's observed times:
Average of Charlene's observed time = 
= 8.5s
Her normal time is therefore: 
= 
= 10s
2. Since no of Charlene's observed time is higher than normal time of 10s, we can therefore conclude that her work perfomance should be rated as slower than normal.
Answer:
b). The average value of the 30 blue-chip stocks is down by 3.2%.
Explanation:
'Dow Jones Industrial Average' also known as 'DJIA' is characterized as the standard indicator to denote the stock-market prices of the shares of the major companies associated with blue-chip in the United States.
As per the question, a down or fall in DJIA by 3.2% would indicate that the stock prices of the companies trading with 'blue-chip' have faced a reduction in their share prices by 3.2% for that day. So, this allows the investors to keep a check on the stock prices and invest accordingly whenever they find it profitable. Thus, <u>option b</u> is the correct answer as the other options fail to convey this idea rather they either talk about the loss of value instead of decrease(in options a and c) or disassociates the entire concept with the stock market(in option d).
The statement that “A multinomial probability distribution describes data that are classified into two or more categories when a multinomial experiment is carried out” is TRUE.
A multinomial experiment has 4 properties:
n repeated trials
various likely outcome
A specific outcome’s chance in happening is fixed
The tests are self-reliant. Meaning, whatever the result of one test won’t affect the results of the other tests.
Answer: d. The invoice amount is greater than $3,300 and less than $3,400.
Explanation:
The terms of the sale are FOB destination, 2/10, n/30. This means that company B will get a 2% discount if they pay in 10 days, if not, they will have to pay in 30 days.
The goods were sold at a list price of $4,200.
Company B returned $750 according to the Credit memo from Company A.
This reduces the transaction amount by that credit memo,
= 4,200 - 750
= $3,450
It is stated that Company B paid within the discount period which was 10 days so they get the discount for a total balance of,
= 3,450 * (1 - 2%)
= $3,381
The answer therefore is option D.
