Step-by-step explanation:
Based on the information given in the question, the expected number of people who pass will be calculated as:
= Probability of passing the driving test × Number of people tested
= 65% × 15
= 0.65 × 15
= 9.75
Therefore, expected number of people who pass is 9.
T≤3
remember that this symbol means less than or equal to
Answer:
55 minutes
Step-by-step explanation:
120-10=110
110/2=55
I think it's 120 seats because:
40%×2=80
10%×4=40
80+40=120 seats
Let the number = x
You have 15 times the number so that is 15x
9 less would be subtracting 9:
15x -9
Is 6 means the equation equals 6:
The equation is: 15x-9 = 6
