What is the median of the following numbers? 1, 2, 2, 8, 9, 14

sesenic [268]

Answer: 5

Step-by-step explanation: The median is the middle number in the data set when the data set is written from least to greatest.

Notice that our data set is already written from least to greatest.

1, 2, 2, 8, 9, 14

Notice that in this data set, there is no middle number directly because 2 and 8 fall directly in the middle. In this situation, we take the average of these two middle numbers and divide their sum by 2.

Since 2 and 8 are the numbers that appear in the middle, we add them.

2 + 8 gives us 10.

Now we divide 10 by 2 to get 5.

So the median of this data set is 5.

Subtract these polynomials.

marta [7]

The correct answer is: [A]: " 4x³ + x² − 11x + 15 " .

_______________________________________________________
<u>Note</u>:
_______________________________________________________

(6x³ − 4x + 5) − (2x³ − x² + 7x − 10) ;

= (6x³ − 4x + 5) − 1(2x³ − x² + 7x − 10) ;
_________________________________________

Examine the following portion of the expression:
_________________________________________
" − 1(2x³ − x² + 7x − 10) " ;

= (-1 * 2x³) − (-1 * x²) + (-1 * 7x) − (-1 * 10) ;

= (-2x³) − (-1x²) + (-7x) − (-10) ;

= (-2x³) + 1x² − 7x + 10 ;

= " − 2x³ + 1x² − 7x + 10 " ;

Now, bring down the other part:

6x³ − 4x + 5 − 2x³ + 1x² − 7x + 10 ;

Combine the "like terms" :

6x³ − 2x³ = + 4x³ ;

− 4x − 7x = − 11x ;

+ 5 + 10 = + 15 ;

and bring down the:

+ 1x² ( which equals: " x² ") ;
____________________________________________________
And rewrite:
____________________________________________________
→ " 4x³ + x² − 11x + 15 " ;

→ which is: Answer choice: [A]: " 4x³ + x² − 11x + 15 " .

When writing 3.7272727272... as a ratio of integers, what is the common ratio?

Law Incorporation [45]

The answer is: "41 / 11 " ; or, write as: " 41 : 11 " .
__________________________________________________________
Explanation:
__________________________________________________________
72/99 = (72÷9) / (99÷9) = 8/ 11 .

So, 3.727272727272... = "3 $\frac{8}{11}$ " .

→ "3 $\frac{8}{11}$ " = [(11 *3) + 8] / 11 = (33 + 8) / 11 = 41 / 11 .
__________________________________________________________
"41 / 11" cannot be simplified any further; so the answer is:
__________________________________________________________
"41 / 11 " ; or, write as: " 41 : 11 " .
__________________________________________________________
