Median of 10, 55, 34, 21
First we arrange number in ascending or descending
10, 21, 34, 55 in ascending.
Median is the middle number and this is between 21 and 34.
We find the average:
(21 + 34) /2 = 55/2 = 27.5
Median is 27.5.
Answer:
The distance is 144
Step-by-step explanation:
We solve this by using the Pythagorean Theorem.
Using the equation: a squared + b squared= c squared.
In this case, 9 squared + b squared = 15 squared.
So 81+b squared = 225
-81 -81
b= 144
Answer:
true, do u need an explanation?
Answer:
k - 3 : k + 2
Step-by-step explanation:
3 less than k = k - 3
2 more than k = k + 2
Ratio of 3 less than k to 2 more than k
In ratios, the word 'to' is represented as a colon :
k - 3 : k + 2
Hope this helps :)
