World Military Expenditure The following chart shows total military and arms trade expenditure from 2011–2020 (t = 1 represents 2011).
†A bar graph titled "World military expenditure" has a horizontal t-axis labeled "Year since 2010" and a vertical axis labeled "$ (billions)". The bar graph has 10 bars. Each bar is associated with a label and an approximate value as listed below.
1: 1,800 billion dollars
2: 1,775 billion dollars
3: 1,750 billion dollars
4: 1,730 billion dollars
5: 1,760 billion dollars
6: 1,760 billion dollars
7: 1,850 billion dollars
8: 1,900 billion dollars
9: 1,950 billion dollars
10: 1,980 billion dollars
(a)
If you want to model the expenditure figures with a function of the form
f(t) = at2 + bt + c,
would you expect the coefficient a to be positive or negative? Why? HINT [See "Features of a Parabola" in this section.]
We would expect the coefficient to be positive because the curve is concave up.
We would expect the coefficient to be negative because the…

Use Graphs A-D for Exercises 9–11. During the winter, the amount of water that flows
down a river remains at a low constant. In the spring, when the snow melts, the flow of
water increases drastically, until it decreases to a steady rate in the summer. The flow
then slowly decreases through the fall into the winter. Consider the graphs shown.

The professor hypothesized that students were spending less time on the material than on the off line material. At the end of the semester, students were asked to provide the amount of time they tended to course tasks during a week. The weeks were classified as online or in person, and the average amount of time is provided for 15 students.

- In Exercises 61–64, find an equation for the level surface of the function through the given point.arrow_forwardDr. Chidi Anagonye studied how self-esteem (high versus low) and success on a school project (passed/succeeded or failed) influences whether students attribute the cause of the outcome to themselves or others. High scores on the dependent variable mean they attribute the outcome to themselves and low scores mean they attributed the outcome to others. Below are his results. Look at the graph below and select the statement that is most true about the graph: Attribution to Self 8 A 9 5 + 3 Low Self Esteem Success High Self Esteem O None of these are accurate Outcome There are 4 independent variables There is definitely an interaction There is definitely not an interaction Failurearrow_forwardCell Phones Using the CTIA Wireless Survey for1985–2009, the number of U.S. cell phone subscribers (in millions) can be modeled byy = 0.632x2 - 2.651x + 1.209where x is the number of years after 1985.a.

- 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. Temperature and Age Babies First Crawl 36 34 32 30 40 50 60 70 80 Average Monthly Temperature (°F) • The line of best fit: crawling age = -0.0777(temperature) +35.7 Correlation coefficient:-0.7 Average crawling age: 31.77 Which statement represents a valid conclusion and justification that the researchers can make as a result of the study? A. Since the correlation coefficient is less than 0, there is insufficient evidence to conclude causation or correlation for this study. Average Crawling Age (weeks)arrow_forwardLarge companies typically collect volumes of data before designing a product, not only to gain information as to whether the product should be released, but also to pinpoint which markets would be the best targets for the product. 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 Amanda 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 97 people in my market category who had been interviewed, 16 said they would buy the product, and of the 101 people in Amanda's market category, 31 said they would buy it.
