Answer:
x = 8
y = 1
Step-by-step explanation:
First you want to substitute y in for 1 to get
2x + 4 = 20
Then subtract four to both sides to get
2x = 16
Then divide 2 by 16 to get
x = 8
and then plug the 8 into the original equation
2(8) + 4y = 20
And then solve for y!

Answer: The range of the tree heights at yard work is greater than the range of the tree heights at the grow station
Step-by-step explanation:
yard works: 7,9,7,12,15
The grow station:9,11,6,12,7
mean of yard works = 7+9+7+12+15/5
=50/5=10
mean of grow station=
9+11+6+12+7 /5
=45/5 =9
The mean of tree heights at yard work is greater than that of grow station.
median(tree at yard work):7,7,9,12,15
median=9
median(tree at grow station)=6,7,9,11,12
median=9
The median of the tree height at yard work is equal to the median of that of tree station.
Range(yard work) = 15 - 7 =8
Range (tree station) =12-6=6
The range of the tree heights at yard work is greater to the tree heights at that of tree station
