Where people turn to for news is different for various age groups. Suppose that a study conducted on this issue was based on 200 respondents who were between the ages of 36 and 50 and 200 respondents who were over age 50. Of the 200 respondents who were between the ages of 36 and 50, 77 got their news primarily from newspapers. Of the 200 respondents who were over age 50, 109 got their news primarily from newspapers. Complete parts (a) through (d). a. Given that a respondent is over the age 50, what then is the probability that he or she gets news primarily from newspapers? ___ (round to four decimal places as needed)
b. Given that a respondent gets news primarily from newspapers, what is the probability that he or she is over 50? ___ (round to four decimal places as needed)
c. Explain the difference in the results in (a) and (b).
o The numerator and denominator of the probability is reversed.
o The conditional events are reversed
o There is no difference in the events (a) and (b).
d. Are the two events, whether the respondent is over age 50 and whether he or she gets news primarily from newspapers, independent? Are or are not.

After a dreary day of rain, the sun peeks through the clouds and a rainbow forms. you notice the rainbow is the shape of a parabola. the equation for this parabola is y = -x2 + 36. graph of a parabola opening down at the vertex 0 comma 36 crossing the x–axis at negative 6 comma 0 and 6 comma 0. in the distance, an airplane is taking off. as it ascends during take-off, it makes a slanted line that cuts through the rainbow at two points. create a table of at least four values for the function that includes two points of intersection between the airplane and the rainbow. analyze the two functions. answer the following reflection questions in complete sentences. what is the domain and range of the rainbow? explain what the domain and range represent. do all of the values make sense in this situation? why or why not? what are the x- and y-intercepts of the rainbow? explain what each intercept represents. is the linear function you created with your table positive or negative? explain. what are the solutions or solution to the system of equations created? explain what it or they represent. create your own piecewise function with at least two functions. explain, using complete sentences, the steps for graphing the function. graph the function by hand or using a graphing software of your choice (remember to submit the graph).

Let us imagine that the number of automobile accidents in a certain region are related to the regional number of registered automobiles in tens of thousands (b1), alcoholic beverage sales in $10,000 (b2), and decrease in the price of gasoline in cents (b3). furthermore, imagine that the regression formula has been calculated as: y = a + b1x1 + b2x2 + b3x3 where y = the number of automobile accidents, a = 7.5, b1 = 3.5, b2 = 4.5, and b3 = 2.5 calculate the expected number of automobile accidents for a football weekend if the region has 25,000 registered vehicles, $75,000 worth of beer is sold, and a gas war causes a 10 cent drop in a gallon of gas.
