Answer:
8 13 14 15 18.
Step-by-step explanation:
The median (the middle number) is 14 so we have
x x 14 x x where x is a single number with each number being different (as there is no mode).
The mean is 13.6 so we have the total numbers
= 13.6 * 5 = 68.
The 4 numbers left must total 68-14 = 54 and the difference between the highest and lowest is 10.
I sense that the lowest and highest will add up to about 1/2 of 54 so:
Try 8 and 18 for these last 2 numbers
The list would be 8 x 14 x 18.
The 2 numbers left will add up to 54 - 26 = 28 . One of these must be < 14 and the other > 14. 13 and 15 would fit.
So a possible data set is:
8 13 14 15 18.
Rearrange the formula to solve for time. Which is the distance over the rate. Then divide 546 meters by 1.3 meters per second. The meter units cancel each other out leaving you with : t: 420.
Answer:
x= -7 y=9
Step-by-step explanation:
3x +9y= 60 [1]
-3x +y=30 [2] rewrite this as the following: y=30+3x
With equation [2] you substitute it into equation [1]
so it will now be: 3x+ 9(30 +3x) =60
3x+270 +27x=60
Group the like terms
3x+27x=60-270
30x=-210
x=-7
Use this answer into the same equation
So: 3(-7)+9y=60
-21 +9y=60
9y=60+21
9y=81
y=9
We gone say C hope this helps
I am not so sure because i have not studied this yet i am very sorry
