Negative association. There is an outlier, the data moves positively, and there is a large cluster in the graph data.
Answer:
A line a and line b
Step-by-step explanation:
Lines b and c are parallel (no intersection points), so the system will have no solutions.
Lines b and d are parallel (no intersection points), so the system will have no solutions.
Lines c and d coincide (infinitely many intersection points), so the system will have infinitely many solutions.
Lines a and b will intersect after extension, so the system of these two equations will have only one solution.
Answer:
7 items
Step-by-step explanation:
Sherry and Laura want to buy a new Ipod. Sherry has already saved $49 and will earn the rest by selling necklaces for $5 each. Laura doesn’t have any money saved, but will sell bracelets for $12 each. How many items must they sell to have the same amount saved for an Ipod?
49 + 5x = y
12x = y
7 items later
49+5(7)=84
12(7)=84
Find the S.A of all the cubes and then add them together.
S.A = 6a²
a is the side length
S.A = 6(3)² = 54
S.A = 6(2)² = 24
S.A = 6(1)² = 6
Now add them all together.
54 + 24 + 6 = 84
So the total surface area is 84
Hope this helps :)
