You know that 1 km=1000 m, then the length of the road
km is
metres.
A group of 8 people are picking up litter along the road and each person is assigned an equal section of the road. The whole road has length 800 m, then for each person will be assigned 800:8=100 m of the road.
If you want to know the length of each part in km, then 1 m=0.001 km and 100 m =1 m·100=0.001 km ·100=0.1 km.
Answer:
I think it 85 because it looks the same as 4
Step-by-step explanation:
Answer:
Perimeter of the square field is 600 meters.
Step-by-step explanation:
Given:
Area of a square field = 2.25 hectares
1 hectare = 10000 m²
∴2.25 hectares =
m²
Now, let each side length of the square field be
meters.
∴ Area = 
⇒ 
⇒
m
Now, perimeter of a square is given as,
.
Here,
m.
∴
m
Hence, the perimeter of the square field is 600 meters.
Answer:
Step-by-step explanation:
Did you mean (1/3)*(-1-4)?
If yes:
(1/3)*-5=
-5/3
or -1 2/3
Or did you mean ((1/3)*-1) -4?
If so:
(-1/3)-4
-4 1/3
or -13/3
Answer:
10.69% probability that all 12 flights were on time
Step-by-step explanation:
For each flight, there are only two possible outcomes. Either it was on time, or it was not. The probability of a flight being on time is independent of any other flight. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
83% of recent flights have arrived on time.
This means that 
A sample of 12 flights is studied.
This means that 
Calculate the probability that all 12 flights were on time
This is P(X = 12).


10.69% probability that all 12 flights were on time
