paid back with simple interest of 15.5% per annum, over a
period of 3 years. The loan was meant to complete the
renovations of her house.

b) How much will she pay over a period of three years?
2.
Tshepo invested R5 500 into a savings account with
compound interest of 14.7% per annum to his further studies
at ABC Business Institution. His course takes six months for a
tuition fee of RS 600.
a) How many months must he save to enable him to comple
the course.
b) His father claims that he will have a surplus of more than
R1 000 after reaching the target for paying his course ve
his claim.​

(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 = --
