The correct answer is C. The mean is found by adding all the numbers then dividing them by however many numbers there are. So for shop b: 5926/8=740.75
For shop a: 5845/8=730.63
Shop a has a lower mean than shop b
Answer: A bag can weigh 13.77 ounces and not need to be repacked.
Step-by-step explanation:
Since we have given that
Mean = 12.08 ounces
Standard deviation = 1.03 ounces
Bags in the upper 5% are too heavy and must be repackaged.
Using the standard normal table.
z = 1.645
So, 
Hence, A bag can weigh 13.77 ounces and not need to be repacked.

Answer:
Step-by-step explanation:
The tangent of the angle can be found using the identity for the tangent of the difference of angles.
tan(α-β) = (tan(α) -tan(β))/(1 +tan(α)tan(β))
The tangent of the angle of each vector is the ratio of the j coefficient to the i coefficient.
tan(α) = -2/3
tan(β) = 4/7
tan(α-β) = (-2/3 -4/7)/(1 +(-2/3)(4/7))
= (-14-12)/(21 -8) = -26/13 = -2
Then the magnitude of the angle between the vectors is ...
arctan(2) ≈ 63.43°
The intersection of A and B, denoted by A ∩ B, is the set of all things that are members of both A and B.
