Assume all variables are binomial. (Note: If values are not found in Previous Table . use the binomial formula.)
High School Dropouts Approximately $10.3\%$ of American high school students drop out of school before graduation. Choose $10$ students entering high school at random. Find the probability that
No more than $2$ drop out

Approximately $10.3\%$ of American high school student smokes. Find the probability of meeting $3$ American high school student smokers out of $6$ American high school student you meet.

Remember to use the largest common factor and to check by multiplying. Factor out a negative factor if the first coefficient is negative.

$$8 x+24$$

Mark each of the following events as independent or dependent. A woman accidentally throw 4 used batteries in with her 12 new batteries. She pulls out a battery, plugs it into her remote, and realizes it was one of the used ones. She throws it away and pulls out another battery. What is the probability this one will also be a used one?

A television advertisement shows a lawyer in a bathing suit coming out of a lake. He says, "If you're in over your head because of bad debts, let us bail you out. We're the best firm in the state." Should there be any restrictions on ads like this? If so, what? Should there be other restrictions on ads? If so, what should they be?

For a business using just-in-time inventory, a delivery of Q items arrives just as the last item is shipped out. Suppose that items are shipped out at a nonconstant rate such that $f(t)=Q-r \sqrt{t}$ gives the number of items in inventory. Find the time T at which the next shipment must arrive. Find the average value of f on the interval [0, T].

In $2010$, there were $40$ million people over $65$ years of age out of a U.S. population of $310$ million. By $2050$, it is estimated that there will be $82$ million people over $65$ years of age out of a U.S. population of $439$ million. Would your chances of meeting a person over $65$ at random be greater in $2010$ or $2050$? Explain.

Identify an advertisement for a product you would consider buying. If the ad appeared in a newspaper or magazine, cut it out and bring it to class. If it appeared online, print it out. If it was aired on the radio or television, either record the ad or write a description of it and bring it to class. Answer the following questions about your ad:

What product or service does the ad promote?

Write an equivalent expression by factoring out the greatest common factor.

$$15 m^4 n+30 m^5 n^2+25 m^3 n^3$$

Carry out the differentiation.
$\displaystyle \frac{d}{dx}\left(\int_x^{x^2} \frac{dt}{1+t^2}\right)$.

Circle the letter of the choice that describes an action potential.
a. Reversal of charges due to the flow of positive ions into a neuron
b. Increase in negative ions in a neuron due to the flow of potassium out of the cell
c. Change to a negative charge due to the flow of sodium ions out of a neuron
d. Reversal of charges due to the flow of negative ions into a neuron

The volume of water in a tank t min after it starts draining is $V(t)=350(20-t)^{2} \mathrm{L}$.

How fast is the water draining out after 5 min? after 15 min?

Read each sentence and decide if the underlined number should be spelled out. If it should, write the spelled-out form above it. If the number is already correct, write $C$ above it.

Example 1. $\underline{152}$ (One hundred fifty-two) students auditioned for the marching band.

The next rest area is $\underline{100}$ miles away.
