Nick works two jobs to pay for college. he tutors for $15 per hour and also works as a bag boy for $8 per hour. due to his class and study schedule, nick is only able to work up to 20 hours per week but must earn at least $150 per week. if t represents the number of hours nick tutors and b represents the number of hours he works as a bag boy, which system of inequalities represents this scenario? a.) t + b greater than or equal to 20 15t + 8b = 150 b.) t + b less than or equal to 20 15t + 8b greater than or equal to 150 c.) t + b less than or equal to 20 15t + 8b less than or equal to 150 d.) none of the systems shown represent this scenario.

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
