There is a difference because in the spring, there may be more days of rain, therefore that would increase the mean for the spring compared to the other days.
Answer: they left home at 8:38
Work:
8:45 + 20 mins = 9:05 (time they arrived)
9:05 - 27 mins = 8:38 (time they left)
Y = 2x³, when x = -3
<span>y = 2*(-3)³
</span>
<span>y = 2*-27
</span>
y = -54
Plus 16 on both side and negative 12plus 16 is 4 so x equals 4
so for A it is 16 times as large because the area is 3*3 which is 9 but since it is a triangle the area is halved and is 4.5 and divide 72 by 4.5 which gives us 16
then for b I believe that the scale factor is 4
and for C it is asking for the bottom side of the scaled copy not of triangle A and 4*3=12 so the bottom is 12
ok now its complete =)
