Let the missing number be x
Mean is the total sum of data over the number of data therefore,
(11+20+x+3+1) / 5 = 9
Then simplify
(35 + x) / 5 = 9
Then multiply 5 to both sides
35 + x = 45
Then subtract 35 to both sides to find x
X= 10
Hope this helps!
Answer:
{x ∈ ℝ | x ≠ 2}
Step-by-step explanation:
Answer:
They are similar because Since all the sides are equal in each triangle, the ratio of corresponding sides will all be equal
Step-by-step explanation:
Answer: Let's solve your equation step-by-step.
2h−3=3
Step 1: Add 3 to both sides.
2h−3+3=3+3
2h=6
Step 2: Divide both sides by 2.
2h/2 = 6/2
h = 3.
