**Answer:**

B

**Step-by-step explanation:**

I believe the answer is E

Midpoint (m) = (x₁ + x₂)/2 , (y₁ + y₂)/2

= (3 - 11)/2, (-5 + 1)/2

= -8/2 , -4/2

= -4 , -2

distance (d) = √[(x₁ - x₂)² + (y₁ - y₂)²

=√ [(-4 - (-2))² + (-2 - 4)²

= √[(-2)² + (-6)²]

= √[4 + 36]

= √40

= 2√10

**Answer:**

it's the 4th one

**Step-by-step explanation:**

A, the one you mentioned

B, the 7th

C, the 8th

D is your answer

203.2 for the first one...and I am 100%sure about it... Because this is what you do to find it... you simply multiply 1016 with 8 and then you divide the answer by 40...easy,,

And for the second one.. it's 15:2 because you are dividing two with 15 students.
