Stacy's present age = x

Laura's present age = 8 + x

Laura's age next year = (8 + x) + 1

Also, Laura's age next year = 3x

Therefore,

3x = (8 + x) + 1

3x = 9 + x

3x - x = 9

2x = 9

x = 9/2

x = 4.5

Laura's present age = 8 + x = 8 + 4.5 = 12.5

Sixty seven percent of the employees in a company have managerial positions, and 58 percent of the employees in the company have

Kazeer [188]

Answer: The proportion of employees who either have MBAs or are managers are 0.58.

Step-by-step explanation:

Since we have given that

Probability of employees having managerial positions = 67%

Probability of employees having MBA degrees = 58%

Probability of managers having MBA degrees = 67%

So, using probability formulas, we get that

$P(A\cup B)=P(A)+P(B)-P(A\cap B)\\\\P(A\cup B)=0.67+0.58-0.67\\\\P(A\cup B)=0.58$

Hence, the proportion of employees who either have MBAs or are managers are 0.58.
