Answer:
I am not sure but think that the answer is 1/20
It is 420,5040,840 and 1680 is divisible by 2,3,4,5 &6.
1.The correlation coefficient is close to B. 0.50
we can conclude that Amélie's cake sales are affected by the daily temperature. <span>A. Strongly</span>
The answer is B.
This is because <span>any angle formed by two chords is equal to half the sum of intercepted arcs.</span>

A. convert the time to seconds, so all the time are 7070sec and the total course to meter.
so 31300meter
Vector = TotalCourse÷total time
V=31300/7070=4.427157m/s
convert it to km/h so 4.427157×36÷10=
15.9377km/h
B. 45÷15.9377=2.823Hour
it means that around 2 Hour 48Minutes more.
i think the teacher need to simplify it
