-9s<-72
\mathrm{Multiply\:both\:sides\:by\:-1\:\left(reverse\:the\:inequality\right)}
\left(-9s\right)\left(-1\right)>\left(-72\right)\left(-1\right)
\mathrm{Simplify}
9s>72
\mathrm{Divide\:both\:sides\:by\:}9
\frac{9s}{9}>\frac{72}{9}
Simplify
s > 8
Probably 2 because It doesn't matter how many beads are in the bag and for 33.34% you would probably draw 2 beads before on the third draw getting a red one and 30% is close to 33.34% then I would you would probably draw 2 beads before drawing a red one.
First you would want to figure out how much tax would be
127 × 0.08 = 10.16
Then you add the tax to the original price
10.16 + 127 = 137.16
And now you have the total cost of the product
137.16
Answer:
The gambler's expected value if he makes the bet is $45.
Step-by-step explanation:
Expected value:
15% probability of a profit of $2000.
100 - 15 = 85% probability of having to pay $300, that is, a loss of $300.
The expected value is each outcome multiplied by it's probability, so:
The gambler's expected value if he makes the bet is $45.
