Answer:
The third picture of the triangles
Step-by-step explanation:
The picture that has the flat edge facing to the right side.
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:
1
Step-by-step explanation:
note that i = , thus
i² = ( )² = - 1
= i² × i² = - 1 × - 1 = 1
Answer:
37.5
Step-by-step explanation:
3/8
3 divided by 8= .0375
.0375 times 100= 37.5
