Answer:

<h3>100 tickets</h3>

Step-by-step explanation:

Probability of winning = amount of tickets purchased/Total number of tickets

20% = 20/total number of tickets

20/100 = 20/total number of tickets

cross multiply

20 * total number of tickets = 20 * 100

20 *  total number of tickets = 100

total number of tickets sold = 100 tickets

Find the vertex of the quadratic function
Galina-37 [17]

Answer:

(1.5,2.5)

Step-by-step explanation:

f(x) = 2x^2 - 6x + 7

Take the first derivative and set it equal to 0 (the slope is 0 at the vertex)

f'(x) = 4x -6

0 = 4x - 6

4x = 6

x = 3/2 or 1.5

If x = (3/2), then y = 2(3/2)^2 - 6(3/2) + 7

y = 2(9/4) - 18/2 + 7

y = (9/2) - 2

y = 2.5

See attached graph.

\bf \textit{area of a trapezoid}\\\\ A=\cfrac{1}{2}h(b_1+b_2)~~ \begin{cases} A=18\\ b_1=5\\ b_2=7 \end{cases}\implies 18=\cfrac{1}{2}h(5+7) \\\\\\ 18=\cfrac{h(12)}{2}\implies 18=6h\implies \cfrac{18}{6}=h\implies 3=h
