Answer:
35.1 units
Step-by-step explanation:
Imagine a right-angled triangle with RS as hypotenuse. The base would be 3 units and the height would be 6 units. By Pythagorus:
RS²=3²+6²
RS=≈6.7 units
Imagine a right-angled triangle with RT as hypotenuse. The base would be 9 units and the height would be 12 units. By Pythagorus:
RT²=9²+12²
RT= = 15 units
Imagine a right-angled triangle with TS as hypotenuse. The base would be 12 units and the height would be 6 units. By Pythagorus:
TS²=12²+6²
TS=≈13.4 units
Perimeter=RS+RT+TS
=6.7+15+13.4
=35.1 units
Answer:
The maximum is :
Now we can calculate the median since the sample size os n =7 the median would be the middle value at the position 4 from the dataset ordered and we got:
Now we can find the quartile 1 we analyze the first 4 values 78, 80,80, 84 and the first quartile would be:
Now we can find the quartile 3 we analyze the last 4 values 84,87, 91, 95 and the third quartile would be:
And finally the 5 number summary would be:
Step-by-step explanation:
We have the following data given:
78, 84, 87, 80, 91, 95, and 80.
The first step is order the dataset on increasing way and we got:
78, 80,80, 84,87, 91, 95
We can begin finding the minimum value and for this case is:
The maximum is :
Now we can calculate the median since the sample size os n =7 the median would be the middle value at the position 4 from the dataset ordered and we got:
Now we can find the quartile 1 we analyze the first 4 values 78, 80,80, 84 and the first quartile would be:
Now we can find the quartile 3 we analyze the last 4 values 84,87, 91, 95 and the third quartile would be:
And finally the 5 number summary would be:
