Answer:

9.5

Step-by-step explanation:

1. Arrange in ascending order

4 5 6 7 8 9 10 11 12

2. Upper Quartile formula:

3×(N+1)÷4

3. Number of terms (N) = 9

4. Apply:

3×(9+1)/4

=3×10/4

=30/4

=7.5th term

5. 7.5th term is the average of the 7th and the 8th term so

Take average

7th term is 9 and 8th term is 10

Which two values of x are roots of the polynomial below?
Julli [10]

Answer:

B. and C.

Step-by-step explanation:

1. Set the polynomial equal to zero:

x² + 5x + 7 = 0

2. Plug the given values of a, b, and c into the quadratic formula:

x=\frac{-5+-\sqrt{5^{2}-4(1)(7) } }{2(1)}

3. Solve the square root:

x=\frac{-5+-\sqrt{25-4(1)(7)} }{2(1)}

x=\frac{-5+-\sqrt{25-28} }{2(1)}

x=\frac{-5+-\sqrt{-3} }{2(1)}

4. Simplify the rest:

x=\frac{-5+-\sqrt{-3} }{2}

5. Separate the solutions:

x=\frac{-5+\sqrt{-3} }{2}  , x=\frac{-5-\sqrt{-3} }{2}

Thus, options B and C are the answers.

hope this helps!

#2 only <br> And it's to confusing
ipn [44]
They are easy to compare if they all have the same common denominator, then you can easily order them by the magnitude of the numerators...

85/10, -67/10, -56/10, 82/10  so now they are easy to compare...so

-6.7, -28/5, 8.2, 17/2

A company has 29900 employees in one country. If this represent 18.3% of the company’s employees, how many employees does it hav
mario62 [17]

Answer:

About 163 388 employees

Step-by-step explanation:

Let total number of employees in the company be represented by x. Thus:

18.3\% \: of \: x = 29900

18.3\% \:x \:  = 29900

\frac{18.3}{100}x = 29900

0.183x = 29900

Divide through by 0.183

\frac{0.183x}{0.183}  =  \frac{29900}{0.183}

x = 163387.9

x = 163388 \: to \: nearest \: whole \: number

The total number of employees in one country is about 163388
