Answer:
There are 23.1% probability of flights getting delayed.
Step-by-step explanation:
Given:
Number of samples of flights selected = 1000
Number of flights arrived on time = 769
We need to find the probability of flight being delayed.
Solution:
Now we will first find the number of flights which are delayed.
number of flights which are delayed can be calculated by subtracting Number of flights arrived on time from Number of samples of flights selected.
framing in equation form we get;
number of flights which are delayed = 
Now we will find the probability of flight being delayed.
probability of flight being delayed can be calculated by dividing number of flights which are delayed from the Number of samples of flights selected and then multiply by 100.
framing in equation form we get;
probability of flight being delayed = 
Hence There are 23.1% probability of flights getting delayed.
Answer:
2.34m/s
Step-by-step explanation:
says that he swim a distance of 50 meters in 21.34 seconds
21.34s = 50m
if we want to know how much it travels in 1 second we would have to divide by the amount of seconds both parts
21.34s = 50m
21.34s/21.34 = 50m/21.34
1s = 2.343m
if in 1 second it makes a distance of 2.343 meters this means that its speed is 2.343 meters over seconds (m/s)
we have to round to the nearest hundredth so that instead of 2.343m/s it would be 2.34m/s
Alright, so we'll be playing a little with variables around here. The question tells you the length of a rectangle is six times its width, or that l=6w.
The perimeter of a rectangle is 2l + 2w (two times the length + two times the width). Since we established that l=6w...
2(6w) + 2w = 98 yd
12w + 2w = 98 yd
14w=98 yd
w=7 yd.
But it doesn't stop there. We found that the width is 7 yd. So the length is 6w, or 6 x 7 yd, which is 42 yd. To find the area of a rectangle, you multiply the length by the width.
So...42 yd x 7 yd = 294 yd^2.
Hope that helped.
