Regression line is a line that clearly describes the behavior of a given set of data.
Regression lines are very essential for forecasting processes. The importance of the line is to describe the interrelation of a dependent variable (Y variable) with one or many independent variables (X variable).
An analyst can forecast future behaviors of the dependent variable by making use of the equation gotten the regression line. This is done by inputting different values for the independent ones. Regression lines are frequently employed in the financial sector.

Answer:
( ¹⁵C₂ )² × 5! = 1082161080
Explanation:
Data provided in the question:
Number of married couples = 15
Therefore,
Number of males = 15
Number of females = 15
Now,
The number of possible dancing arrangements
= Probability of selecting males × Probability of selecting males × ways of arranging 5 pairs
= ¹⁵C₂ × ¹⁵C₂ × 5!
= ( ¹⁵C₂ )² × 5!
=
× ( 5 × 4 × 3 × 2 × 1 )
=
× ( 5 × 4 × 3 × 2 × 1 )
=
× 120
= 1082161080
Determine how much each month she can afford
Answer:
The Journal entries are as follows:
(i) Sale of Equipment
Cash A/c Dr. $20,300
Accumulated Depreciation A/c Dr. $22,500
To Equipment $40,000
To Gain $2,800
(To record the sale of equipment)
(ii) Sale of Equipment
Cash A/c Dr. $12,700
Accumulated Depreciation A/c Dr. $22,500
Loss A/c Dr. $4,800
To Equipment $40,000
(To record the sale of equipment)
Workings:
Accumulated Depreciation = [(40,000 - 2,500) ÷ 5] × 3 years
= 7,500 × 3 years
= $22,500
