Answer:
Step-by-step explanation:
Let the 4 greatest numbers be, A, B, C D
(A + B + C + D)/4 = 8
Total sum = 4 × 8
= 32
Let the 4 lowest numbers be, D, E F G,
(D + E + F + G)/4 = 20
Total number = 4 × 20
= 80
Hence, the difference between the sums of the 3 greatest number and the 3 smallest numbers:
A, B, C and E, F, G
= D + (E + F + G) - (A + B + C) - D
= (E + F + G) - (A + B + C)
= 80 - 32
= 48.
The answer is: 2y^2-20y+12
Answer:
$230,000
Step-by-step explanation:
Contribution margin = Sales - Variable costs
=($250,000 - $137,500)
= $112,500
Contribution margin ratio = Contribution margin ÷ Sales
= ($112,500 ÷ $250,000)
= 0.45
Basically
Break-even sales = Fixed expenses ÷ Contribution margin ratio
=($103,500 ÷ 0.45)
= $230,000
Answer: reversed.
Step-by-step explanation:
1. By definition, when you multiply or divide both sides of an inequality by the same negative number, then the direction of the inequality symbol must be reversed.
2. To understand this better, let's write the inequality shown below:
The symbol > means "greater than".
If you multiply both sides of the inequality by -1, you obtain:
(This is false, because -4 is not greater than -2)
But, if the symbol is reversed, then:
(This is true because -4 is less than -2)
The symbol < means "less than".
