The IDs are of the form DDDDDLL, where D is a digit and L is a letter. There are 10 digits and 26 letters in English.
This gives you 10*10*10*10*10*26*26 possible combinations, or that many possible students who can use that system.
That’s 67,600,000 students.
A and B are insdependent if prob (A and B) = prob(A) x prob(B)
Answer:
1.75
Step-by-step explanation:
A geometric progression or sequence is a series of numbers with a special property where the ratio between each consecutive number is the same. This number is called the common ratio.
We can test whether the sequence is geometric by dividing consecutive numbers as follows:
So we can see that the common ratio is 1.75.
Starting balance : 986.24
deductions :
car payment : 203.34
gas bill : 96.67
debit card : 67.12
ATM : 30
total deductions : 203.34 + 96.67 + 67.12 + 30 = 397.13
deposits :
check : 1289.60
cash : 45
total deposits : 1289.60 + 45 = 1334.60
Balance to date : 986.24 + 1334.6 - 397.13 = 1923.71 <==
