Answer:
16.5
Step-by-step explanation:
Given data to us is ,
- 20, 15, 14, 16, 17, 12, 20, 22 .
Arrange it in ascending order .
= 12 , 14 , 15 , 16 , 17 , 20 , 20 , 22
The middle most observation will be median in case n is odd and average of middlemost observations if n is even , that is n = 8 .
=> Middlemost observations = 16 , 17
=> Mean = 16 + 17 /2 = 33/2 = 16.5
Answer:

Step-by-step explanation:
Answer:
171
Step-by-step explanation:
Q~r
find k (k is the constant)
Q=kr
76=k×20
76=20k divide 20 on both sides giving you
k=3.8
then Q=k×r
Q=3.8×45
Q=171
Answer:
∠ABC=90°
Step-by-step explanation:
if ∠DAB =110 then ∠BAC =180-110 =70° because straighht lines make 180°∠s
use the fact that the sum of angles in a Δ is 180°
∠ABC= 180-20-70= 90
Answer:
Step-by-step explanation:
10 - m = m - 10 is one solution
7x + 5 = 7(x + 5) is no solution
3(t + 2) = (2 + 3t) + 4 is identity
hope this helps!
mark me brainliest :D
