4) Mr. ABC believes that there has been an increase in the number of tornadoes in city XYZ. The increase of tornadoes per region since 1970 can be represented by the equation t = 4.5y + 250, where y is elapsed time in years since 1970 and tis tornadoes per region. Which statements are supported by Mr. ABC's belief? Choose all that are correct. a) In 1970, the tornadoes per region were about 4.5 (Hint: Plug in zero for y) b) If the trend represented by the equation continues, the tornadoes will be about 430 in 2010.(Hint: plug in the number of years since 1970 to 2010 and see what you get) c) In 1970 the number of tornadoes per region was about 250 (Hint: Plug in zero for y) d) The equation shows that the increase in tornadoes per region from one year to the next is 4.5 e) If the trend represented by the equation continues, the tornadoes will be about 9,115 in 2010 (Hint: plug in the number of years since 1970 to 2010 and see what you get) f) The equation shows that the increase in tornadoes per region from one year to the next is 250
