  • 1900 : 14/25 = 0.56
    1910 : 29/50 = 0.58
    1920 : 53/100 = 0.53
    1930 : 13/20 = 0.65
    1940 : 3/5 = 0.6

    in order of increasing ring width (least to greatest) : 1920, 1900, 1910, 1940, 1930

    which year was the hottest : 1930
    how do u know ....because the problem states that a greater width corresponds to a higher average temperature. So the one with the greatest width will have the hottest temperature

    which year was coldest : 1920
    how do u know....greater width, higher temperature. So the one with the smallest width will have the lowest temperature
    ========================
    third and fourth level below ground level....-3 and -4
    ground level ...0
    first and fourth level above ground.....1 and 4
    the reasoning : if ground level is 0, then anything above ground level will have positive numbers and any level below ground level will have negative numbers

    graph : solid circle on -4, solid circle on 4, shading in between...I guess, unless they just want you to plot ur points

    the order in which they will be searched :  -4,-3,0,1,4

    if she takes the stairs....
    -4 to -3 is 1 flight of stairs
    -3 to 0 is 3 flights of stairs
    0 to 1 = 1 flight of stairs
    1 to 4 is 3 flights of stairs
    for a total of : 8 flights of stairs
