Answer:
y=3
Step-by-step explanation:
The line of symmetry is the line along which the figure could be rotated and nothing would change (the orig. figure and the reflected figure would overlap completely). You see the midpoint of the left side of the figure is (-2,3) while the midpoint of the right side of the figure is (1,3). This would make the line passing through these two y = 3
Answer: $4.55
Step-by-step explanation:
Just subtract $10.00 from $5.45 and you will get $4.55
Answer: No. The intervals defined by the margin or error overlap
Step-by-step explanation:
If we think about it, with the worst margins, 55% could be 48% and then the 45% would be 52%, showing there is no clear yes or no and it is possible that the intervals could overlap
Answer:
The corresponding pair of sides are in the same ratio.
Step-by-step explanation:
For two triangles to be similar, the theorem that is required is the corresponding sides of the two triangles are in the same ratio.
Now, see the diagram of two triangles given with the question.
The ratios of the corresponding sides are 
If two pairs corresponding sides are in 5 : 4 ratio, then the third pair of corresponding sides will also be in 5 : 4 ratio.
Therefore, the two triangles are similar. (Answer)
