Answer:
18
Step-by-step explanation:
The average is found by adding all the numbers and dividing by 5
(2+ 81+ 29+ 18+ x)/5 = 26.8
Multiply each side by 5
(2+ 81+ 29+ 18+ x) = 134
x+130 =134
Subtract 130 from each side
x = 4
Now we want the median
List the numbers in order from smallest to largest
2,4,18,29 ,81
The median is the middle
X=1.5 and y=3.5 by using simultaneous equations you can see when you substitute x as 1.5 and y as 3.5
Step-by-step explanation:
0,1
3(5x−37x+1)−4(7x+15x−3)=11;x=53,−71
Take $7 and divide it by 12.
7/12 = 0.58
