Which algebraic expression is a polynomial? 4x2 – 3x + StartFraction 2 Over x EndFraction –6x3 + x2 – StartRoot 5 EndRoot 8x2 +
stealth61 [152]

Answer:

Step-by-step explanation:

"4x2 – 3x + StartFraction 2 Over x EndFraction" is definitely not a polynomial because one of the exponents of x is negative.

"–6x3 + x2 – StartRoot 5 EndRoot" is a polynomial because all of the exponents of x are integers 0 or greater.  

The presence of any root (fractional exponents included) of the variable x automatically disqualifies such expression:  it's not a polynomial.

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\%.

4. I need help with question in the attached picture!
Arisa [49]

ANSWER

D. 13

EXPLANATION

We have

f(x) =  \frac{2x + 1}{x - 4}

To find

{f}^{ - 1} (3)

means we want to find an x-value whose image is 3.

\frac{2x + 1}{x - 4}  = 3

We cross multiply,

2x + 1 = 3(x - 4)

Expand:

2x + 1 = 3x - 12

Combine like terms,

3x - 2x = 12 + 1

x = 13

\therefore{f}^{ - 1} (3)= 13
