1. the minnesota dept. of transportation hoped that they could measure the weights of big
trucks without actually stopping the vehicles by using a newly developed "weight-in-
motion" scale. to see if the new device was accurate, they conducted a calibration test.
they weighed several trucks when stopped (static weight). they weighed them again
while the trucks were moving to see how well the new scale could estimate the weight. a
regression printout is shown below:
the regression equation is
static weight = 10.9 + 0.638 weight in motion (thousands of pounds)

Need fast will mark brainliest ^^)based on the work you have completed in this lesson, you are going to create a transcript for a persuasive presentation to convince your client that your design improvement is the best possible solution for their needs. take your client through the different design options you considered for the product design improvement. explain why you discarded the designs that were not the best possible solution. finally, explain why your final product design covers each of the requirements and specifications you used to create your needs statement. your speech must include visual aids that include at least two schematics, or detailed illustrations, of your design. each schematic might show a different angle of your design. or the schematics might show different parts and pieces of the design. if you are unfamiliar with product schematics, find examples by doing an internet search for product schematicsno schematic neededcreate a transcript for a persuasive speech that includes schematics for your design.(just convince people to buy something anything you can think of use your own imagination)
