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
Answer:
The second one
Step-by-step explanation:
The graph of each exponential function 
passes through the point (0,1), because 
Thus, the only possible choice is C.
Check it:
The set C could be generated by exponential function 
Answer:
24c
Step-by-step explanation:
Difference= big value - small value
When minus is put side by side, it becomes a plus.
17c-(-7c)=17c+7c=24c
Answer:
7.) 16.7
Step-by-step explanation:
7). First you have to find the length of the line with the triangle that is at a 90 angle with the longest side of the triangle
Using the pythagrorem theorem a² + b² = c²
4² + b² = 5²
b² = 5² - 4²
b² = 25 - 16
b² = 9
√b² =√9
b = 3
next you do the same thing to find the missing segment of the longest side
3² + b² = 13²
b² = 169 - 9
b² = 160
b = √160 or ≈ 12.7
12.7 + 4 = 16.7
so 16.7 is the length of that side
