Katherine is younger than Alexandra. Their ages are consecutive integers.
Serjik [45]

Using equations to solve the word problem, Katherine's age is 8 years

<h3>Word Problem</h3>

Word problem are often mathematical problem that are represented in words and sometimes can be solved using an equation.

To solve this problem, we have to represent the problem using mathematical equations;

Let;

Katherine's age = x²

Alexandra = 5(x + 1)

Sum of their age = 109

5(x + 1) + x² = 109

5x + 5 + x² = 109

x² + 5x - 104 = 0

Solving for the equation; x = 8

Katherine's age is 8

A company has an opportunity to bid on three contracts. Determine which would be the best investment given the information in th
MariettaO [177]

CONTRACT  PROFIT, (P)* OF PROFIT...(P)*. TO BREAK EVEN...LOSS, (P)* OF LOSS

Southeast $45,000,            50%                       30%                           $6,000, 20%

Southwest $60,000,            35%                      40%                          $10,000, 25%

California $112,000,           20%                       40%                          $40,000, 40%


I think that the best contract would be with SOUTHEAST. It probability of having a profit is higher than the other two at 50% while its probability of incurring a loss is lesser than the other two at 20%. 

Despite the bigger value of its contract profit of the other two, these value will still be greatly affected by its corresponding probabilities.
