Answer:
C
Step-by-step explanation
Since 1 2/3 is too large for the blank, and 0.153 is too small, we try C, which is 22%. Convert it to a fraction to make 11/50. If you cross multiply, we would find out that 11/50 is a greater fraction than 2/11 and less than 1.42. Hence, we get C as our answer.
Answer:




Step-by-step explanation:
Solving
using the distributive property:


Subtract 0.8 from both sides


Divide both sides by -0.2


Answer:
1 : 4
Step-by-step explanation:
12c : 48c ( divide both parts by 12c )
= 1 : 4
Answer:
Mean = 8
Variance = 22
Standard deviation = 4.6904
Step-by-step explanation:
To find out Mean the formula is : total sum of data set / number of values
(11 + 11 + 3 + 1 + 11 + 11) / 6 = 48 / 6 = 8
Mean = 8
Now for variance we will form a table
x 11 11 3 1 11 11
(x - Mean) 3 3 -5 -7 3 3
(x - Mean)² 9 9 25 49 9 9
Now we the formula of variance =
Variance = (9+9+25+49+9+9)/(6-1) = 110/5 = 22
Variance = 22
Now we know Standard deviation = √(variance)
Therefore standard deviation = √22 = 4.6904
