Sylvia is organizing a small concert as a charity event at her school. She has done a little research and found the expression -10x + 180 represents the number of tickets that will sell at an event given that X represents the price of the ticket. Explain why the income of the event can be represented by the expression -10x^(squared) + 180x. If all the expenses add up to $150, explain why the expression -10x^ +180x-150 represents the profit. Please help. Thank you in advance and I can't make a number squares on this device so ^ is the symbol I used for squares

The weight of 46 new patients of a clinic from the year 2018 are recorded and listed below. construct a frequency distribution, using 7 classes. then, draw a histogram, a frequency polygon, and an ogive for the data, using the relative information from the frequency table for each of the graphs. describe the shape of the histogram. data set: 130 192 145 97 100 122 210 132 107 95 210 128 193 208 118 196 130 178 187 240 90 126 98 194 115 212 110 225 187 133 220 218 110 104 201 120 183 124 261 270 108 160 203 210 191 180 1) complete the frequency distribution table below (add as many rows as needed): - class limits - class boundaries - midpoint - frequency - cumulative frequency 2) histogram 3) frequency polygon 4) ogive
