The bar graph shows the average price of a movie ticket for selected years from 1980 through 2013. The graph indicated that in 1980, the average movies ticket price was $2.69. For the period from 1980 through 2013, the price increased by approximately $0.17 per year. If this trend continues, by which year will the average price of a movie ticket be $9.49?

- In the situation of the example, how long could you keep the car if your expense account allowed 242?arrow_forwardGreek Mythology Can the Greek hero Achilles, running at 20 feet per second, ever catch a tortoise, starting 20 feet ahead of Achilles and running at 10 feet per second? The Greek mathematician Zeno said no. When Achilles runs 20 feet, the tortoise will be 10 feet ahead. Then, when Achilles runs 10 feet, the tortoise will be 5 feet ahead. Achilles will keep cutting the distance in half but will never catch the tortoise. The table shows Zeno’s reasoning. In the table, both the distances and the times required to achieve them form infinite geometric series. Using the table, show that both series have finite sums. What do these sums represent?arrow_forwardIf you receive a 5% pay raise and then a 5% pay cut is your salary the same? Why or why not? Demonstrate your answer using actual valuesarrow_forward

She has a passion for economics but will only follow her passion if she can determine whether economics graduates are paid well in the labour market (if not, she will choose to study accounting). She decides that if economics graduates earn, on average, R250 000 per year within five years of graduation she will pursue the study of economics.Bilqees asks her older sibling, an econometrician, to help her estimate the average salary of economics graduates based on a small sample using confidence interval estimation. She interviews a sample of eight recent economics graduates who are currently employed in order to investigate whether the average salary is at least as high as her requirement. These data are handed to her sibling for confidence interval estimation and are given below (measured in thousands of rands): X 287 196 276 252 275 325 204 185 Question 1: What is the…arrow_forward
