Mean, mode, med
86, 12, 11, 12, 15, 29, 59, -40

Step-by-step explanation: so first u wanna put them in order -40, 11, 12, 12, 15, 29, 59, 86

The median is pretty much the number in the middle so it’s 15. Mode is the number that repeats the most so it’s 12. And mean is adding all the numbers together and then dividing it by how many numbers are there. So it is 23

answer:   the paragraph proof is mentioned below.

step-by-step explanation:

given: in a δxwy where

such that, ∠wzx ≅ ∠yzx and zw≅zy

we have to prove that: segment zx is a perpendicular bisector of segment wy.

prove: since, zw≅zy ⇒ ∠wzy is a supplementary angle.

then, ∠wzy= 180°

⇒∠wzx + ∠yzx = 180° ( because xz divides ∠wzy into two parts)

but, ∠wzx ≅ ∠yzx ( given)

⇒∠wzy+∠wzy=180° ( by substitution)

⇒2∠wzy=180°

⇒∠wzy=90°

⇒∠wzy=∠yzx =90°

therefore, xz⊥wy where wz=zy

⇒zx is a perpendicular bisector of wy.
