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:
C
Step-by-step explanation:
A. 2*6 = 12 but 24p*2 doesn't equal 24p
B. 3*9 doesn't equal 12, and 3*21p doesn't equal 24p
C. 4*3 equals 12 and4*6p=24p
D. 6*2=12, but 6*3p doesn't equal 24p
I hope this helps!!!
Answer:
6x+3y
Step-by-step explanation:
Answer:
4x^2 + 21x - 18
Step-by-step explanation:
(9x^2+24x-8)-(5x^2+3x+10)
9x^2+24x-8-5x^2-3x-10
9x^2 - 5x^2 = 4x^2
24x - 3x = 21x
-8 - 10 = -18
Answer: 4x^2 + 21x - 18
(x-3)=-3x+25
Because we know that y=x-3 so we put that in place of y in the equation
