The student council is hosting a drawing to raise money for scholarships. They are selling tickets for $9 each and will sell 500
ryzh [129]

Answer:

-$2.32

Step-by-step explanation:

Give that

The selling price per ticket is $9

And the number of tickets sold is 500

So,

There is one grand prize, three $300 second prize, and eleven $40 third prizes

We need to find out the expected value of the profit

= \frac{1}{500} \times 2000 +  \frac{3}{500} \times 300 + \frac{11}{500} \times 40\\\\

= 4 + 1.8 + 0.88

= 6.68

Now the expected profit is

= $6.68 - $9

= -$2.32

Max spends three times as long on his math homework than he does on his science homework. If he spent total of 64 minutes on mat
den301095 [7]

Let X = science homework.

Then math homework would be 3x ( three times as long).

Now you have math plus science = 64 minutes:

x  + 3x = 64

Combine like terms:

4x = 64

Divide both sides by 4:

x = 64 / 4

x = 16

He spent 16 minutes on science and 48 minutes on math.
