Answer:
2.236
Step-by-step explanation:
You need to use the distance formula.
d= square root of (x2-x1)^2=(y2-y1)^2
AB is proportional to XY since they are similar triangles making it 25:10 or 5:2
so then AC:XZ would be 5x:2x and 5x:6 so then its 15:6 since x is 3 basically set up proportions and so value of the big triangle to the small triangle would be at rails os 5:2
Answer:
Consistent and dependent
Step-by-step explanation:
Given
Required
The words that describe the equations
Make y the subject in (2)
Collect like terms
Divide through by 2
Substitute: in (1)
Collect like terms
Solve for x
Simplify
Substitute in
So, we have:
and
<em>The system is consistent because it has at least 1 solution</em>
<em>The system is dependent because it has more than 1 solution</em>
Answer:
16
Step-by-step explanation:
first term/(1-ratio)
8/(1-1/2)
8/1/2 = 16
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
