Answer:
Option c) Sample space
Step-by-step explanation:
Given that a family has two children.
Let M represents male, and F represents female.
In probability theory, the sample space (also called sample description space or possibility space) of an experiment or random trial is the set of all possible outcomes or results of that experiment. A sample space is usually denoted using set notation, and the possible ordered outcomes are listed as elements in the set. It is common to refer to a sample space by the labels S, 
, or 
(for "universal set"). The elements of a sample space may be numbers, words, letters, or symbols. They can also be finite, countably infinite, or uncountably infinite.
Let S be the sample space of the given data.
Here the sample space is typically the set {male, female}, commonly written 
ie, S is the set 
or 
For the gender of the children, corresponding sample space would be 
, commonly written as
S is the set or 
Answer:

Step-by-step explanation:
Process
1.- From the graph, determine which points are the solution to the inequalities.
The solution will be all those points where the three inequalities cross.
First line. Dotted blue line. We observe that the solution is all the points over this line.
Second line. Straight violet line. We observe that the solution is all the points below the inequality.
A. It is a solution
B. it is not a solution
C. It is not a solution
D. It is a solution
E. It is not a solution
F. It is a solution
Answer:
3mph
Step-by-step explanation:
From Igor we find that the distance is 2x6= 12 miles
Distance/Time = Speed
12 miles/4 hours = 3mph
Answer:
cost of a burger= $4.5
Cost of soda = $3.5
Cost of a slice of pizza = $5.5
Step-by-step explanation:
Let x = the cost of a burger.
Let y = the cost of a soda.
Let z = the cost of a slice of pizza.
Louis bought a burger and soda for $8. This means
x + y = 8 - - - - - - - -1
Kate purchased a slice of pizza and soda for $9. This means
z + y = 9 - - - - - - - - - 2
David purchased a burger, a slice of pizza, and a soda for $13.50. This means
x + y + z = $13.50 - - - - - - - 3
Substituting x = 8-y and z = 9-y in equation 3, it becomes
8-y + y + 9-y = 13.50
-y -y + y = 13.50 -8-9
-y = -3.5
y = $3.5
Put y = 3.5 in equation 1
x + 3.5 = 8
x = 8 - 3.5 = $4.5
Put x = 4.5 and y = 3.5 in equation 3.
4.5 + 3.5 + z = 13.5
8 + z = 13.5
z = 13.5 - 8 = $5.5
