Step-by-step explanation:
Answer: the probability that we observe 4 cracks when inspecting a 3 m2 section is 0.034
Step-by-step explanation:
The formula for poisson distribution is expressed as
P(x = r) = (e^- µ × µ^r)/r!
Where
µ represents the mean of the theoretical distribution.
r = x represents the number of successes of the event(cracks).
From the information given,
µ = 3 cracks per 1 m² section
It means that for a 3 m² section of the aircraft, the average number of cracks would be 9
the probability that we observe 4 cracks when inspecting a 3 m2 section would be
P(x = 4) = (e^- 9 × 9^4)/4!
P(x = 4) = 0.034
There are 12 inches in a foot, so we can simply divide the amount of inches (100) by 12 to get the amount of feet.
100ipm/12
Hope this helps!
*ipm stands for inches per minute.
Answer:
If I budget 12% of my monthly income for grocerises and I earn $950 bi-weekly.
Now, the term 'Biweekly' has an ambiguity. Given that in some countries like the UK, Ireland and Australia it means 'Every two weeks' but in other countries it means 'Twice every week'. In this case, we're going to solve both cases:
- Case #1: Biweekly means every two weeks.
In this case, I would earn $1900 a month. Now, 12% percent of my monthly income is: 0.12 × $1900 = $200.
Therefore, I would spend $200 a month in groceries.
- Case #2: Biweekly means twice a week.
In this case, I would earn $1900 a week or $7600 a month . Now, 12% percent of my monthly income is: 0.12 × $7600 = $912.
Therefore, I would spend $912 a month in groceries.
Probably, the exercise refers to case #1. But just in case, I considered both cases.
Answer:
ratio of boys to girl=5:3
let boys be 5x and girls be 3x
5x=3x+24
2x=24
x=12
no. of girls=3×12
=36
