- Just a general tip: Zoom away further from the camera to capture the question clearer.
- Calculate the Total: 31 students
- A= 4/31= 13%
- (A+B)/31 = 14/31 = 45%

Answer:
a₁ = 23/100 and r = 1/100
S = 23/99
Step-by-step explanation:
The sum of an infinite geometric series is:
S = a₁ / (1 − r)
where a₁ is the first term of the series and r is the common ratio.
0.23 repeating is 0.232323... To convert this to a fraction using the above equation, first we must write this as a series:
0.23 repeating = 0.23 + 0.0023 + 0.000023 + ...
The first term is 0.23, and the common ratio is 0.01.
Therefore, a₁ = 0.23 and r = 0.01. Or, in fraction form, a₁ = 23/100 and r = 1/100.
Plugging this into the equation, we can convert 0.232323... to a fraction.
S = (23/100) / (1 − 1/100)
S = (23/100) / (99/100)
S = 23/99
Answer:
There are 67,600 possible combinations for this vault.
Step-by-step explanation:
First dial: 100 possible values
Second dial: 26 possible values
Third dial: 26 possible values.
How many possible combinations are there for this vault?
Multiplication of these values. So
100*26*26 = 67600
There are 67,600 possible combinations for this vault.
