The second graph or the letter B
Answer:
D. We can label the rational numbers with strings from the set (1, 2, 3, 4, 5, 6, 7, 8, 9, / -) by writing down the string that represents that rational number in its simplest form. As the labels are unique, it follows that the set of rational numbers is countable.
Step-by-step explanation:
The label numbers are rational if they are integers. The whole number subset is rational which is written by the string. The sets of numbers are represented in its simplest forms. The rational numbers then forms numbers sets which are countable.

Answer:During 10years ago the number of people living in Sherbury increased by 965 while the number of people living in Yaston increased by 942
Step-by-step explanation:
During the 10 year period,
Let x= increase in the number of
people living in Sherbury
y=number of people living in Sherbury before the increase
Therefore,
5/100 * y = x
0.05y=x
And
x + y = 20265
But y=20x
x + 20x =20265
21x=20265
x=965
During 10years ago the number of people living in Sherbury increased by 965.
Likewise
Let
a=increase in the number of
people living in Yaston
b=number of people living in Yaston before the increase
7.5/100 * b = a
0.075b = a
b=13.33a
a + b = 13502
a + 13.33a=13502
14.33a=13502
a=942
During 10years ago the number of people living in Yaston increased by 942.
Conclusion
During 10years ago the number of people living in Sherbury increased by 965 while the number of people living in Yaston increased by 942.
