P = 4ft
Explanation:
take 5 and 3, add them together = 8. "straight down to double its distance" so that would mean to do either 8 divided by 2 or 4 x 2. 4 x 2 - 3 = 5 (5 = final position). p = 4ft
The answer is D. Ratio. When ever you see “per” another number it’s a ratio.
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:
3
Step-by-step explanation:
2 x 7= 14 - 17= 3
Answer:
- 1/4
- 3/5
Step-by-step explanation:
You find the part by expressing the ratio as a fraction, then simplifying.
1. 5/20 = (1·5)/(4·5) = (1/4)·(5/5) = 1/4
5 is 1/4 of 20.
__
2. 12/20 = (3·4)/(5·4) = (3/5)·(4/4) = 3/5
12 is 3/5 of 20.
