Answer:
3.14ft²
Step-by-step explanation:
Area of a circle= πr²
= 3.14 x 1²
= 3.14 x 1
= 3.14 ft²
Answer:
Collection of numerical information is called Statistics
Step-by-step explanation:
From the Oxford dictionary, the definition of statistics (science) is: "the practice or science of collecting and analyzing numerical data in large quantities, especially to infer proportions in a whole from those in a representative sample".
While the definition of statistic (data) is: "a fact or piece of data obtained from a study of a large quantity of numerical data".
Statistics is a science, not a method, therefore answer can´t be a).
Not all sample data is necessarily a statistic, therefore answer can´t be b).
All statistics are numerical information.
Not all statistics are population data, therefore answer can´t be d).
Cleaned data is information filtered with a specific criterion, but not necessarily used in a statistic.
The most probable answer is c.
Answer:
0.714 ; 0.556 ; (A1 n A2 n A3) = 0
Step-by-step explanation:
Given that :
P(oil) = 0.35
P(filter) = 0.45
P(oil n filter) = 0.25
1)
P(filter | Oil) = P(oil n filter) / P(oil)
P(filter | Oil) = 0.25 / 0.35 = 0.714
11)
P(Oil | filter) = P(oil n filter) / P(filter)
P(Oil | filter ) = 0.25 / 0.45 = 0.556
Number of red aces = 2
Queen or king = 4 + 4 = 8
Number on card greater than 3 and less than 8 = {4,5,6,7} = 4 card ; for 4 suits = 4 * 4 = 16
Total number of cards in deck = 52
Choosing without replacement :
Hence,
A1 = 2 / 52
A2 = 8 / 51
A3 = 16 / 50
(A1 n A2 n A3) ;this means card common to all three events.
However, (A1 n A2 n A3) = 0 because ;
1.) No red ace card is greater than 3 and less than 8.
11.) An ace card can neither be a king nor a queen
ratio of perimeter is the same as ratio of sides so perimeter would be 1:4
since area is in square units you need to square the ratio (1:4)^2 which is 1:16
Answer:The integers are -13, -12 and -11.
Step-by-step explanation:
Let the four numbers be n, n+1, n +2, and n+3
Therefore (n )+ (n+1 )+(n+2) + (n +3) = -46
4n + (1 +2+3) = -46
4n + 6= -46
Subtract 6 from both sides to get the value of n
4n +6 - 6= -46 -6
4n = -52
Divide both sides by 4
n = -52/4
n = -13
Therefore, n + 1 = -13 + 1= -12
n + 2= -13 + 2 = -11
The integers are -13, -12 and -11.
