Answer: A B
Group 1 0.25 0.75
Group 2 0.44 0.56
Step-by-step explanation:
Since we have given that
Number of people of A in group 1 = 15
Number of people of B in group 1 = 45
Total number of people in group 1 is given by
Relative frequency of people of A in Group 1 is given by
Relative frequency of people of B in Group 1 is given by
Similarly, Number of people of A in group 2 = 20
Number of people of B in group 2 = 25
Total number of people in group 2 is given by
Relative frequency of people of A in Group 2 is given by
Relative frequency of people of B in Group 2 is given by
Hence, A B
Group 1 0.25 0.75
Group 2 0.44 0.56
Inequalities are used to relate expression with unequal values
The inequality that describes the scenario is:
The baseball cards, you have received are:
The total baseball cards, you received are:
So, we have:
You want to have a total of 500 or more before 18.
This means that:
Where c represents the number of baseball cards, you need to collect on your own
Substitute
Collect like terms
Hence, the inequality that describes the scenario is:
