Use the following information to answer the question. The projected number of hip fractures per year in a Western country is graphed below. For this graph the equation of the line of best fit is determined using the formula Number of fractures per year = 7000 (number of years after 1980) + 120 000 where the number of fractures per year is in hundreds of thousands Projected Number of Hip Fractures 5- (in hundreds of thousands) Number of fractures per year 3 1980 2000 2020 2040 Year The year in which the number of hip fractures equals 500 000 isanswered Marked out of 1 V Flag question \"'3 Mathematics 302 [5 cr] CL (2021) Vista Virtual School 147648 ' Emily Scarlett In an experiment, the volume, V, of 1 kg of water is measured as its temperature, T, is increased.
