Answer:
2694.86957
Step-by-step explanation:
61982/23=2694.86957
The answer to this would be 40 because you multiply 12x0.30 and get 40 which mean 12 is 30% of 40 total
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:
x = -12
Step-by-step explanation:
Let's solve your equation step-by-step.
8+x=−4
Step 1: Simplify both sides of the equation.
x+8=−4
Step 2: Subtract 8 from both sides.
x+8−8=−4−8
x=−12
Answer:
14 dimes and 4 quarters
Step-by-step explanation:
x= number of dimes
y=number of quarters
x-10=y
0.10x+0.25y=2.40
substitute for y
0.10x+0.25(x-10)=2.40
0.35x-2.50=2.40
0.35x=4.90
x=14
y=4
