Answer:
0.98732
Step-by-step explanation:
Given that :
Mean = 10 minutes
Variance = 2 minutes
For less than equal 40 jobs
Mean (m) = 40 * 10 = 400 minutes
Variance = 2 * 40 = 80 minutes
Standard deviation (s) = √variance = √80
Converting hours to minutes
X = 60 * 7 = 420 minutes
P(X≤ 420) :
Z = (x - m) / s
P(X≤ 420) :
Z = (420 - 400) / √80
Z = 20 / √80 = 20 / 8.9442 = 2.236
P(Z ≤ 2.236) = 0.98732

Answer:
0
Step-by-step explanation:
Since displacement is the distance between the journey starting point and the final point if they both are the same the difference becomes zero and hence the displacement.
Displacement = final point - initial point
(<em>both</em><em> </em><em>are</em><em> </em><em>same</em><em>)</em>
<em>=</em><em> </em>same - same
= 0
