x=44 since angle a and c is congruent
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:
I'm not really sure but I think it's 2
Step-by-step explanation:
So here's what I did;
x³+3x-9=x - 1 +2x
x³+3x - x -2x = 9 - 1
x³= 8
x = ³√8
x = 2
I hope this helps
