The data below are the temperatures on randomly chosen days during a summer class and the number of absences on those days.
Find the standard error of estimate, se, given that y = 0.449x - 30.27.

Temp (x) 72 85 91 90 88 98 75 100 80

Number of 3 7 10 10 8 15 4 15 5

Absences (y)

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
