4 0

Answer:

Step-by-step explanation:

To find the axis of symmetry, you use the equation opposite of <em>b</em>, divided by 2(<em>a</em>). Your <em>a </em>will always be the first number, your <em>b</em> your second, and <em>c</em> your third. So your equation would be positive <em>x</em>/2(x^2). I'll let you figure this out on your own.

Of all the employees,what is the approximate relative frequency of Managers who worked more than 40 hours ?
elena-14-01-66 [18.8K]

Answer:

The approximate relative frequency of Managers who worked more than 40 hours will be  9.3\%.

Step-by-step explanation:

The complete question is mentioned below in the attached diagram.

From the question diagram which is attached below, it is clear that

  • there are total 86 employees, and
  • there are 8 are who work more than 40 hours per week.

Hence, the approximate relative frequency of managers who worked more than 40 hours will be:

                                   \frac{8}{86}=0.093  

Which is is equal to 9.3\%.

Therefore, the approximate relative frequency of Managers who worked more than 40 hours will be  9.3\%.
