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.
By the order of operation, we first do the operation in parentheses
( 6 * (2 + 15) ) /3 = (6* 17)/3 = 102 / 3
Then we do the division
Answer = 102 / 3 = 34

Answer:
y = x + 5
Step-by-step explanation:
The line passes through points (-7,-2) and (2,7)
Slope of the line = change in y ÷ change in x = 
= 1
Taking another point (x,y) on the line;
Slope = 
= 1
Cross multiplying this gives;
y - 7 = x - 2
y = x + 5
