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.
i hope this helps you......
Answer:
5. 100/b+24 6. 5m+13
Step-by-step explanation:
5. The quotient means Divide. The sum means Add. So / is z symbol for division. 100 divided by b plus 24.
6. More means to Add and the product means to multiply. So instead of putting m times 5, you would put 5m. First you would put 5m+ 13 b/c of the "than".
Answer:
y ≤ 1/3 x - 1.3.
Step-by-step explanation:
First find the equation of the line:
The slope = (-0.3 - (-1.3) / (3 - 0).
= 1/3 so the equation is y = 1/3x + b where b is a constant.
b is the y-intercept which is the value of y when x = 0 . We see that it is -1.3 ( from the point 0, -1.3).
Since the line is continuous and the shading is below this line the inequality sign is 'less than or equal to', ≤.
A, C, and E.
you can check them by putting into y=mx+b form. if m is negative then as domain increases range decreases.
