Answer:

The maximum revenue will be $R=\$25,000$ at price $p=\$100.$

Step-by-step explanation:

Given:

$R=-2.5p^2+500p$

Find the vertex of the parabola represented by given equation:

$p_v=\dfrac{-b}{2a}=\dfrac{-500}{2\cdot (-2.5)}=\dfrac{500}{5}=100$

When $p=\$100,$ then

$R=-2.5\cdot 100^2+500\cdot 100=-2.5\cdot 10,000+50,000=-25,000+50,000=25,000$

The maximum revenue will be $R=\$25,000$ at price $p=\$100.$

Kim rolls a dice and flips a coin

KATRIN_1 [288]

Since, both the events are independent.

So, P(A+B) = P(A)×P(B)

a) P( Head & Getting a 2 ) = P( head ) × P( Getting a 2 )

$=\dfrac{1}{2}\times \dfrac{1}{6}\\\\=\dfrac{1}{12}$

b) P( Even number & Tail ) = P( Even number ) × P( Tail )

$=\dfrac{3}{6}\times \dfrac{1}{2}\\\\= \dfrac{1}{4}$

Hence, this is the required solution.
