A park ranger wants to know the mean number of nights students in your school plan to camp next summer. The park ranger randomly surveys 10 students from each class. The results are shown
Nights Camping
A: 0, 5, 2, 3, 0,6, 0, 10, 3,0
B: 14.0.0, 6.5, 0. 1. 2.2.5
C: 8, 8, 2, 3, 4, 1, 0, 0, 0,6
D: 10, 10, 5, 6, 1, 0, 0, 0, 4.0
a. Use each sample to make an estimate for the mean number of nights students in your school plan
camp next summer.

D
Mean
2.9 3.5 3.2 3.6

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

i dont know

step-by-step explanation:

umm. i dont know

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.

hey pal. the answer is b plz mark as brainliest
