Answer:
∠AEX = 70°
Step-by-step explanation:
From the diagram
AX ≅ BX
BY ≅ CY
AZ ≅ CZ
∠XAE = 20°
A circumcenter has equal distant from vertices of the triangle since radii of circles are congruent.
For the given figure, the midpoints is at Z, X, Y
And the perpendiculars also occur at Z, X, Y
∠Z = 90°
∠X = 90°
∠Y = 90°
∠XAE ∠AXE +∠AEX= 180° (sum of angles in a triangle)
∠AXE = ∠X = 90°
20° + 90° +∠AEX= 180°
110° +∠AEX= 180°
∠AEX = 180°-110°
∠AEX = 70°
Mean:
Add all the numbers:
13 + 17 + 15 + 18 + 21 + 13 + 20 + = 16.7
16.7 + 3.7 = 20.4
Mean = 20.4
Median:
Order the numbers:
13, 13, 15, 17, 18, 20, 21
The median, or middle number is 17.
17 + 3.7 = 20.7
Median = 20.7
Mode:
The number that repeats the most is 13.
13 + 3.7 = 16.7
Mode = 16.7
Range:
Highest Number = 21
Lowest Number = 13
21 - 13 = 8
Range = 8
The answer choice that matches is choice A.
