Answer: I think the answer is -12 81/200 ( please let me know if this answer is wrong )
S=((u+v)/2)t
S=displacement (distance)
U=initial velocity
V=final velocity
T=time
For A: Mean is $37.60 The mean is an excellent representation of the data, because the variability is so small. Both stores have medians close to the means, but the IQR is much less for the first store.

For B: Mean is $48.53. Here, there is a lot of spread, and the mean is not as good a representation of the data.

So the first term a=12
the formula for arithmetic sequence is
xn=a +d(n-1)
x16th= 12+d(16-1)=-8
12+15d= -8
15d = -8-12
d=-20/15= -4/3
the common difference is d =-4/3
Step-by-step explanation:
m∠3 = 7x - 10
m∠6 = 5x + 10
m∠3 = m∠6
7x - 10 = 5x + 10
7x - 5x = 10 + 10
2x = 20
x = 20/2 = 10°
