Adata set lists the number of times a machine breaks each month in a shoe factory over the past year. for this data set, the minimum is 4, the first quartile is 6, the median is 8, the interquartile range is 3, and the maximum is 20. construct a box-and-whisker plot that shows the number of times the machine breaks.

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions. a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0

He ! a group of farmers planned to clean 80 acres of wheat per day to finish the work on schedule. right before the work started, they received a new piece of machinery that them clean 10 more acres per day than originally planned. as a result of increased productivity in the last day before the deadline they only had to clean 30 acres. how many acres of wheat did the group of farmers have to clean?

The dash figure is a dilation if the original figure. find the scale factor. classify the dilation as an enlargement or a reduction
