Answer:
A: 171.75
B: 170
Step-by-step explanation:
The mean (or average) can be found by...
- add all the numbers together (we will call this y)
- divide the total sum (or y) by the total amount of numbers used to add
Formula:
(x₁ + x₂ + x₃ + ... + xₙ) ÷ n
For A:
(172 + 130 + 173 + 212) ÷ 4 = 171.75
For B:
(136 + 184 + 168 + 192) ÷ 4 = 170
Answer:
The scale factor is
Is a reduction
Step-by-step explanation:
we know that
The scale factor is the ratio of the corresponding side of resulting triangle by the corresponding side of the first triangle
Let
z-----> the scale factor
x------> the corresponding side of resulting triangle
y------> the corresponding side of the first triangle
so
In this problem we have
substitute
The scale factor is less than one
therefore
Is a reduction
