How would you calculate the number of ways to perform the following task? A bicycle lock has a code made up of 4 digits. The code can be made by selecting each digit from the choices 0 through 9 and repetition is allowed. How many different combinations are possible? 10x10x10x A committee is being selected to organize the Valentines Day party. If the committee is to be made up of 4 females and 1 male from a group consisting of 6 girls and 9 boys, how would you calculate the total number of committees possible? 6C4 x 9 The following table shows a probability distribution with only four outcomes. What number correctly completes the table? Outcome Probability Outcome 1 1/2 = 0. Outcome 2 1/4 = 0. Outcome 3 1/8 = 0. Outcome 4 _______________ 1/16 = 0. When calculating the P(EUF), you must determine if the two events _______________________________________________________________. are overlapping or non-overlapping
On a standardized test there are 5 multiple-choice answers to choose from. If you do not know the answer and have to guess, the probability that you guess correctly is 1/5 and the probability you guess incorrectly is 4/5. You will receive +1 point if you guess correctly and will receive - 1/4 point if you guess incorrectly. The overall expected value is 0. What is the best explanation for the meaning of "the expected value is zero"? Since the expected value is zero, in the long run, guessing would not have a positive or negative impact on my score. The following table shows the breakdown of participation in the (fictitious) Olympic Winter events involving 3 local universities. Use the table to answer the question below. ___Dust______Mistletoe______Tumble Weed_____Ice_______Total Sledding___Harvesting_____Chasing_______Sculptures M_200_________350__________ 150_______________100_______________ F __175_________300___________125______________200_______________ Total_375_____650___________275_____________300______________ How would you calculate the following? If I randomly select a participant from this population, what is the probability I select a participant that participated in the Dust Sledding event OR is male? (375/1600)+(800/1600)-(200/1600) Using the table from the problem above, If I randomly select a participant from this population (table above), what is the probability I select a participant that is a female GIVEN they participated in the Ice Sculpture event? 200/ Read each scenario below. If the scenario represents theoretical probability, place a T beside it. If the scenario represents empirical probability, place an E beside it. (Please make sure your letters are distinct
0....Sept....Oct....Nov....Dec....Jan....Feb....Mar What does the scale on the left beginning with 0 and ending with 7 represent? Number of cases of candy sold. Using the chart above, what was the total amount of candy sold during the school year shown in the graph? 27.5 cases From January 3 to January 7, Buffalo recorded the following daily high temperatures: 5 degrees, 7 degrees, 6 degrees, 5 degrees, and 7 degrees. Which statement about the temperatures is true? mean = median Chocolate bars produced by a certain machine are labeled as 8.0 oz on the package. HOWEVER, the distribution of the ACTUAL weights of these chocolate bars is normal with a mean of 8.1 oz and a standard deviation of 0.1 oz. Using the 68- 95 - 99.7% Rule, approximately what proportion of chocolate bars would you expect to have weights between 7.9 and 8.1 oz? 47.5% The area (or percentage of the data) under the normal curve (for a standard normal distribution) between z=0 and z=1 is _____________ the area under the normal curve between z=1 and z=2.
greater than The five number sum are of a set of data ______________________________________________________________________________. is the minimum, the first (or lower) quartile, the median, the third (or upper) quartile, and the maximum The mean for each graph is given. Which graph(s) below represents the data with the largest standard deviation? Graph B Below is a scatter plot showing the relationship between the sale price and the size of 10 large industrial properties that appeared in the paper. The sale price is represented by y in millions of dollars and the size is represented by x in thousands of square feet. "Using Regression Analysis in Real Estate Appraisal" (Appraisal Journal [2002]) Which of the following numbers is closest to the correlation (r-value) between x and y?
Using the following scatterplot to determine which of the four choices best describes the plot. The chart shows the relationship between a student's entering ACT and the students current GPA. There is a positive correlation between ACT and GPA. Stock prices for TGIF have tripled in the last few days. When something triples in price, this represents a percent increase of _________. 200%
A loan that requires the borrower to pay the same payment every period until the maturity date (until the loan is paid down to 0) is called a ___________________________. amortized loan In a typical loan amortization schedule, the total dollar amount of money paid each period ______________________________________. (Referring to the pmt sent to the bank each period.) remains constant with each payment In a typical loan amortization schedule, the total dollar amount of interest paid each period____________________________________________________________. decreases with each payment Suppose that 5 cards are drawn from a well-shuffled deck of cards. How many outcomes are possible in which all 5 cards are diamonds? 13C
