Step-by-step explanation:
Part A
The function representing the amount of money in account A after x years is represented by the function
f(x) = 9,628(0.92)x
The amount of money in account A is decreasing by 8% per year.
Part B
The table showing the amount g(r), in dollars, of money in account B after r years with number of years given as 1 2 3 4 and amount in dollars) 1,375 1,512.50 1,663.75 1,830.134.
Looking at the table,
The change per year is
(1512.5 - 1375)/1375 = 137.5/1375 = 0.1
The percentage change is 0.1× 100 = 10%
The amount in account B increases by 10%
Therefore, account B recorded a greater percentage change in amount of money over the previous year since the change in account B is 10℅ which is greater than 8% in account B

There are
female teachers, and
male teachers.
This means that, out of a total of 75 teachers, 45 are female, leading to a probability of
of selecting a female teacher.
If we restrict to those with more than 8 years service, there are 13 female teachers and 7 male teachers.
So, out of a total of 21 teachers, there are 13 female teachers, leading to a probability of
of selecting a female teacher.
