Answer:
The correct answer is letter "D": when the actual price is less than the standard price.
Explanation:
Direct labor rate variance compares the existing direct labor costs and normal direct labor costs over the same operating period. Favorable variance in the labor rate can be caused by hiring more unskilled employees, reducing the minimum wage, and incorrectly setting indirect labor costs. Favorable variance takes place when the <em>costs of direct labor are efficient or lower compared to the standard</em>.
In this problem we are given the mean of $1100, SD of $150 and x equal to $900. In this case, we need to use the z-score table to answer the problem:
z = (x-mean)/sd
z = (900-1100)/150
z = -1.33
from z-table, the probability at the left of z= -1.33 is equal to 9.18%
Answer:
The correct answer is: a positive correlation.
Explanation:
Correlation can say something about the relationship between variables. It is used to understand:
1. If the relationship is positive or negative
2. The strength of the relationship.
Correlation is a powerful tool that provides vital pieces of information.
In the case of family income and family spending, it is easy to see that both rise or fall together in the same direction. This is called a positive correlation.
In the case of price and demand, the change occurs in the opposite direction, so that the increase in one is accompanied by a decrease in the other. This is known as a negative correlation.
Answer:
D. 5.00
Explanation:
The calculation of current ratio is given below :-
Current Ratio = Current Assets ÷ Current Liabilities
where,
Current Asset = cash + account receivable + office supply
= $400 + $1000 + $600
= $2,000
and the Current Liabilities is
= Account payable + salary payable
= $300 + $100
= $400
So, the current ratio is
= $2,000 ÷ $400
= 5 times
Answer:

Explanation:
quantity demanded in this market @ $2= 3+2+1=6
quantity demanded in this market @$1.50 =4+5+3 =12
Net increase in quantity demanded is 12-6 = 6
