Answer:
1.25
Step-by-step explanation:
Because they are equal triangles, all of their sides are equal
so, lets take one side of each triangle (4, 5)
the law:
the scale factor = the larger side ÷ the smaller side
x = 5 ÷ 4
x = 1.25
For checking:
the larger side = the smaller side × the scale factor
Y = 4 × 1.25
Y = 5

Answer:
19.714
Step-by-step explanation:
Given :
Yearly Tuition Frequency
12-16 5
17-21 4
22-26 3
27-31 2
We calculate the midpoint (x) = (lower + upper) / 2
The mean yearly tuition :
The midpoint (x) :
X ___ F ___ Fx
14 __ 5
19 __ 4
24 __ 3
29 __ 2
The mean = Σfx / Σf
Σfx / Σf = (14*5 + 19*4 + 24*3 + 29*2) / (5+4+3+2)
Mean = 276 / 14
Mean yearly tuition = 19.714
