Question Help
Challenge A cell phone plan costs $26.90 per month for 400 minutes of talk time. It costs an additional
$0.05 per minute for each minute over 400 minutes. To get e-mail access, it costs 20% of the price for 41
minutes of talk time. Your bill, which includes e-mail, is the same each month for 7 months. The total cos
for all 7 months is $257.46. Write and solve an equation to find the number of minutes of talk time you us
each month.
Let m represent the number of minutes over 400 minutes each month. Which equation represents the
given situation?

(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 = --

At a local museum, the total price for one adult and one child is $11. mrs. smith paid for herself and her three children. she spent $19. record the system of equations to be solved and then find the price of an adult and child ticket using either elimination or substitution.

What are linear equations? could'ya explain too me, ? ! and how do you see what graph is a proportional relationship?
