Several months ago, I was interviewed by such a company while shopping at a mall. I was asked about my exercise habits and whether or not I'd be interested in buying a video/DVD designed to teach stretching exercises. I fall into the male, 18 – 35-years-old category, and I guessed that, like me, many males in that category would not be interested in a stretching video. My friend Diane falls in the female, older-than-35 category, and I was thinking that she might like the stretching video. After being interviewed, I looked at the interviewer's results. Of the 93 people in my market category who had been interviewed, 17 said they would buy the product, and of the 113 people in Diane's market category, 34 said they would buy it.

- The line graphs in Figure show the percentages of marriages ending in divorce based on the wife’s age at marriage.Here are two mathematical models that approximate the data displayed by the line graphs:In each model, the variable n is the number of years after marriage and the variable d is the percentage of marriages ending in divorce.a. Use the appropriate formula to determine the percentage of marriagesending in divorce after 10 years when the wife is over 25 at the time ofmarriage.b. Use the appropriate line graph in Figure to determine the percentageof marriages ending in divorce after 10 years when the wife is over 25 at the time of marriage.c.

This question was investigated by the authors of a paper that appeared in the Biological Bulletin (August 2007). Researchers measured carapace (the exterior shell) length of 27 laboratory-raised lobsters of known age. The data on x = carapace length (in mm) and y = age (in years) in the following table were read from a graph that appeared in the paper.

Trust in government hit an all-time low of 14% in 2014, while trust in the media bottomed out at 32% in 2016. The bar graph shows the percentage of Americans trusting in the government and the media for five selected years. Use this information to answer parts a-c. a. Use the information in the graph to estimate the yearly loss in the percentage of people trusting in government. The yearly loss in the percentage of people trusting in government is 36 %. (Round to the nearest tenth as needed.) b. Write a mathematical model that estimates the percentage, P, of people trusting in government x years after 2003.

- The bar graph shows median yearly earnings of full-time workers in the United States for people 25 years and over with a college education, by final degree earned. (See the attached graph). The median yearly salary of an American whose final degreeis a doctorate is $45 thousand less than twice that of an American whose final degree is a bachelor’s. Combined, two people with each of these educational attainments earn $198 thousand. Find the median yearly salary of Americans with each of these final degrees.arrow_forwardHow do I solve c, d, and e with the given data?arrow_forwardYou may use a calculator for this item. To investigate whether air temperature influences the age at which a baby learns to crawl, researchers conducted a study of 414 babies. The graph and accompanying statistics provide information about the average monthly temperature, in degrees Fahrenheit (F), when a baby was six months old and the average age, in weeks, when the baby first started to crawl.
