The monthly failure rate is q = 5% = 0.05
The monthly pass rate is p = 1 - q = 0.95
We want to determine the probability of 12 passes in 12 consecutive months for a student.
P(12 of 12 successes) = ₁₂C₁₂ p¹² q⁰ = 0.95¹² = 0.5404.
Therefore if we have 100 students, the number that gets through 12 consecutive months is
100*005404 = 54 students.
Answer: 54 students are left after 12 months.
Answer:
first one is c and second one is acute
Step-by-step explanation:
acute angle which is 45
Group like terms, in this case terms with variables and terms without. (m + 11) + (n + 44) = (m + n) + (11 + 44) Then simplify. (m + n) + (11 + 44) = (m + n) + 55 = m + n + 55 Final answer: m + n + 55
Answer:
The answer is 90
Step-by-step explanation:
95+68+82+75+x/5 = 82
320+x = 410
x=410-320
x=90
