Fast forward a few years…and suppose you need to get your car repaired. You see the ads above. Your father, who knows a bit about cars, says it will probably take 3 hours to fix your car. How do you determine where you should take your car to get it repaired? 1. Write an equation for each repair shop to represent the total cost of the car repair as a function of the number of hours worked. Let x = number of hours worked Let y = total cost to you Mike’s Repair Shop Amy’s Auto Repair 2. Now, use the substitution or elimination method to find the point of intersection. Show your work below: Auto Repair Problem “Which auto repair service should I use?” MIKE’S REPAIR SHOP $100 Service Charge plus $65 per hour AMY’S AUTO REPAIR $40 Service Charge plus $80 per hour Alexia Gibson 1/29/2021 Y= 65x+100 Y= 80x+40 3. At what point do the two lines intersect? 4. What is the meaning of the point of intersection in the context of this problem?5. If it will only take 3 hours to fix your car: a. Which company would be cheapest? b. What is the cost? Show your work below: 6. If it takes 6 hours to repair the car a. Which company would be cheapest? b. What is the cost? Show your work below: 7. Which repair shop do you think is advertising to encourage customers with quick repairs to use their services? Explain why.

That table shows measurements (in invhes$ from cubes with different side lengths. which pairs of variables have a linear relationship? check all that apply

(c) compare the results of parts (a) and (b). in general, how do you think the mode, median, and mean are affected when each data value in a set is multiplied by the same constant? multiplying each data value by the same constant c results in the mode, median, and mean increasing by a factor of c. multiplying each data value by the same constant c results in the mode, median, and mean remaining the same. multiplying each data value by the same constant c results in the mode, median, and mean decreasing by a factor of c. there is no distinct pattern when each data value is multiplied by the same constant. (d) suppose you have information about average heights of a random sample of airline passengers. the mode is 65 inches, the median is 72 inches, and the mean is 65 inches. to convert the data into centimeters, multiply each data value by 2.54. what are the values of the mode, median, and mean in centimeters? (enter your answers to two decimal places.) mode cm median cm mean cm in this problem, we explore the effect on the mean, median, and mode of multiplying each data value by the same number. consider the following data set 7, 7, 8, 11, 15. (a) compute the mode, median, and mean. (enter your answers to one (1) decimal places.) mean value = median = mode = (b) multiply 3 to each of the data values. compute the mode, median, and mean. (enter your answers to one (1) decimal places.) mean value = median = mode = --
