Answer:
x ≥ 7
Step-by-step explanation:
multiply both sides of the equation by 4
2x - 6
4 × ---------- ≥ 2 × 4
4
2x - 6 ≥ 8
2x ≥ 8 + 6
2x ≥ 14
2x 14
-------- ≥ ---------
2 2
x ≥ 7
24x + 8 would be the anwser
I’m pretty sure the answer is no
Answer: 23.7 lb
Step-by-step explanation:
Mean m = 15 lb
Standard deviation d = 3.3 lb
To determine the surcharge weight, we need to know the highest weight of 99% of the parcels.
P(z<x) = 0.99 = ¢(Z)
Z = 2.33
Since Z = (x - m)/d
x = dZ + m
x = 3.3*2.33 + 15
x = 22.689 lb approximately
x = 22.7 lb
Therefore, the highest weight for 99% if the parcels is 22.7 lb.
That is, the surcharge weight = 22.7 + 1 = 23.7 lb
