Vikentia [17]

Answer:  \text{ D) } 9.72

We can write,

2.7 \times(-3)\times (-1.2) = 2.7 \times 3.6  ( because -a\times -b = ab)

2.7 \times(-3)\times (-1.2) = 9.72

⇒ Option D is correct.

Hello please can some one help me I don’t know how to do these math
erik [133]
1) Put all the numbers in numerical order :
15, 23, 24, 25, 25, 25, 27
The median is the middle of the numbers : 25
Mode is the value that occurs more often : 25

2) Put all the numbers in numerical order :
2, 3, 3, 3, 3, 4, 4, 5
The middle of the numbers is 3 and 3
so, 3 + 3 = 6
6 : 2 = 3

Median = 3
Mode = 3


3) Put all the numbers in numerical order :
5, 7, 8, 9, 9, 10, 10, 10, 12
Median = 9
Mode = 10

4) Put all the numbers in numerical order :
0, 1, 1, 2, 2, 3, 3, 3, 4, 4

Median
2 + 3 = 5 : 2 = 2,5
Mode = 3


5) Put all the numbers in numerical order :
12, 13, 15, 18, 25
Median = 15
Mode = 0 (None)

6) Put all the numbers in numerical order :
1, 1, 2, 2, 3, 3, 3, 4, 4, 4, 5
Median = 3
Mode = 3 and 4

7) Put all the numbers in numerical order :
6, 8, 9, 10, 10, 12

Median
9 + 10 = 19 : 2 = 8
Mode = 10


8) Put all the numbers in numerical order :
28, 30, 30, 30, 30, 31, 31, 31, 31, 31, 31, 31

Median
31 + 31 = 62 : 2 = 31
Mode = 31
