Answer:
<h2>The lengths of the bases of the trapezoid:</h2><h2>
42/h cm and 84/h cm.</h2>
Step-by-step explanation:
The formula of an area of a triangle:
<em>b</em><em> </em>- base
<em>h</em> - height
We have <em>b = 21cm, h = 6cm</em>.
Substitute:
The formula of an area of a trapezoid:
<em>b₁, b₂</em> - bases
<em>h</em><em> - </em>height
We have <em>b₁ = 2b₂</em>, therefore <em>b₁ + b₂ = 2b₂ + b₂ = 3b₂</em>.
The area of a triangle and the area of a trapezoid are the same.
Therefore
<em>multiply both sides by 2</em>
<em>divide both sides by 3</em>
<em>divide both sides by h</em>

Answer:
Probability that there will be a seat available for every passenger who shows up is 50/50 or 49/50
Step-by-step explanation:
Since it is known that 5percent of people who make reservations would not show up.
Therefore 5% of 52 sold ticket is
5/100 x 52 = 2.6
That is 2 or 3 people who make reservations would not show up.
Which means 52 - 2 or 52 - 3 people would show up
50 or 49 people would show up
Since the flight can hold just 50 people
The probability that everyone that shows up would have a seat is therefore =
50/ 50 or 49/50
