Answer:
3
Step-by-step explanation:
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:
226 grams
Step-by-step explanation:
This will be an exponential function. The formula for exponential functions and half life is A=Ao * (1/2)^(t/h)
A stands for final amount, Ao for initial amount, 1/2 is the decaying factor (after a half life, one mg becomes 1/2 mg), t stands for time, and h is the half life.
To solve your problem, the equation would be A=904 * (1/2)^(70/35)
The parentheses are necessary for your calculator or else you will get the wrong answer.
