Which strategies can be used to solve this problem?
the candle factory made 1,200 candles per month in june and july and 1,345 candles per month in august and september. what is the total number of candles they made in four months?
choose all answers that are correct.

a. use logical reasoning.
multiply 1,200 by 2 to figure out how many candles were made in june and july. multiply 1,345 by 2 to figure out how many candles were made in august and september. add the two numbers together to find the total number of candles made in four months.
b. draw a diagram.
draw two circles. in one circle write 1,200 and in the other circle write 1,345. add the numbers in the circles together.
c. work backward.
divide 1,200 by 2 (for the 2 months, june and july). then divide 1,345 by 2 (for the 2 months august and september). add these two numbers.
d. translate into an equation.
1,200 × 2 + 1,345 × 2 = c

(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 = --
