Aconcrete mix is designed to withstand 3000 pounds per square inch (psi) of pressure. the following data represent the strength of nine randomly selected casts (in psi). 3970, 4100, 3100, 3200, 2950, 3830, 4100, 4050, 3460 compute the mean, median and mode strength of the concrete (in psi). compute the mean strength of the concrete. select the correct choice below and, if necessary, fill in the answer box to complete your choice. a. the mean strength of the concrete is nothing psi of pressure. (round to the nearest tenth as needed.) b. the mean does not exist.

What is the explicit rule for the sequence in simplified form? −1,−4,−7,−10,−13… an=4−5n an=−4−3n an=2−3n an=−6−5n

Have you ever been in the middle of telling a story and had to use hand gestures or even a drawing to make your point? in algebra, if we want to illustrate or visualize a key feature of a function, sometimes we have to write the function in a different form—such as a table, graph, or equation—to determine the specific key feature we’re looking for. think about interactions with others and situations you’ve come across in your own life. how have you had to adjust or change the way you represented something based on either the concept you were trying to describe or the person you were interacting with? explain how the complexity or layout of the concept required you to change your style or presentation, or how the person’s unique learning style affected the way you presented the information.
