Answer:
The 2 box-and-whisker plot is the correct one.
Step-by-step explanation:
The first step you need to do is write the numbers from least to greatest.
5, 7, 8, 10, 13, 14, 17, 17, 21. 5 and 21 will be the end points.
To make the box we need to find the median first. All you have to do is pick the middle number and it is 13. That just leaves box-and-whisker plots 2 and 3.
To find the first and third quartile, you need to take the other numbers from 13 to the left (10+8+7+5) and add them up then divide by 4 to get 7.5 and that is the first quartile.
To find the third quartile, you will go from 13 to the right (14+17+17+21) and divide by 4 to get 17.25.
This equals the 2nd box-and-whisker plot.
Answer : The correct option is
Step-by-step explanation :
According to the BODMAS rule, when the expression contains brackets open ((), {}, []) we have to first simplify the bracket followed by of (powers and roots etc.) and then we have to solve the division, multiplication, addition and subtraction from left to right order (respectively).
The given expression is:
Thus, the given expression is equivalent to
Frequency
= (pi)/(2pi)
= 1/2
If sounds travel 335 meters in 1 second , in 1 minute it travels 60 times that distance :
335m × 60 = 20100 meters
Sounds travel 20100 meters per minute
if 1000 meters = 1 km ,
20100 meters = 20100/1000 km
20100 meters = 20.1 Km
Awnser : Sound would travel 20.1 km in one minute
Answer:
I think this is the answer for the second question.
