Astraight line is drawn through the points (3.0, 23.87 3 104), (10.0, 212.99 3 104), (20.0, 225.93 3 104), (30.0, 238.89 3 104), and (40.0, 251.96 3 104) to give m 5 21.298 72 3 104, b 5 256.695, um 5 13.190, ub 5 323.57, and sy 5 392.9. express the slope and intercept and their uncertainties with reasonable signifi cant figures.

47.28 or 47.2857143

step-by-step explanation:

you just divide 331 by 7 and you get that answer. ( i think so tho)

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).

192/15 = 12.8.

12.8

step-by-step explanation:

192/15 is 12.8.

however, it says to round to the nearest foot, which would equal 13.
