Answer:
5
Step-by-step explanation:
hello :
a + b = 9
...(*)
a - b = 6...(**)
add (*) and (**) : 2a =15.....(1)
subsct (**) and (*) : 2b=3 ....(2)
now divid (1) , (2) : 2a/2b = 15/3
means : a/b = 15/3 =5
Answer:

3 A. 6/20
Step-by-step explanation:
1
The more times you run a probability-based trial, the more likely you are to get close to the theoretical frequency.
2
Since 1 and 2 represent goals, just find the options that have three/four 2's and 1's. These are 5212, 2152, 2512, and 2112. Since there are 4 options out of 20, we can say our probability is 4/20
C
Since 1 and 2 represent goals, we have to find the options where there are no 1's or 2's. These are 6643, 3554, 4533, 6634, 4536, and 5546. Since there are 6 options out of 20, we can say our probability is 6/20
Answer:
A
Step-by-step explanation:
The per capita income is the income of a person in a nation. The per capita is calculated by dividing the gross income of the nation by total population.
Let
Pci = Per Capita Income
I = Total income
and
P = Total population
Then,
Pci = I/P
