11. You want to buy a triangular lot measuring 1500 feet by 1860 feet by 2490 feet.  The price of the land is $2200 per acre.  How much does the land cost? (Hint: 1 acre = 43,560 square feet).   Special Notes: Answer should be either an integer or rounded decimal to the hundredths place.  Work is required.

An informative speech potentially provides a speaker the opportunity to learn more about a topic he or she might be interested in knowing more about.

8. Two observers, 3.2 miles apart, notice a hot air ballon between them.  One observer calculates the angle of elevation to the balloon to be 30°, while the other observer calculates the angle of elevation to the balloon to be 40°.  Find the height of the balloon.    Special Notes: Answer should be either an integer or rounded decimal to the hundredths place.  Work is required.

When giving a public speech, the more technical the speaker can be the better.

The following tables summarize responses from a survey asking college students to respond to the following question: “Within the last 30 days, how often do you think the typical student at your school used alcohol?” Both men and women responded to this question. Use the data below to calculate the observed chi-square statistic. **Report your answer to 4 decimal places.   Perceptions of Typical Alcohol Use Gender Never 1 + Days Daily Female 10 48 37 Male 7 54 41  

Solve the following equations, finding all possible solutions.  Answers should be in radians. Your work for each problem must be clear and legible in your submission. Each problem is worth 4 points.  8.  

Which of the following is a recommended tip for preparing the introduction of a speech?

Which of the following is the appropriate way to report a statistically significant chi-square statistic in a research report?

Do this Single-line indirect Truth Table. If there are any “problems” be sure to show by underlining/highlighting the “problem”. Points taken off for not showing the “problem”. Be sure to put your T/F values under the correct main operators! The letter is never a main operator (unless there’s nothing else on that side).   You will answer Valid or Invalid on the next question.   (Z + ~K) v ~(O v E)  /  (E v X) > ~(Z + ~M) // ~M > ~E Here are the Truth Function Rules:   ~ P   P + Q P v Q P >  Q P = Q F T    T  T  T    T  T  T   T  T  T    T   T  T T F    T  F  F    T  T  F   T  F  F    T  F  F        F  F  T    F  T  T   F  T  T    F  F  T        F  F  F    F  F  F   F  T  F    F  T  F
