Answer:
2.1
Step-by-step explanation:
Given :
Radios(X):_0 ___ 1 ___2 ___ 3 ___4 ___5
P(X=x) : 0.03 0.20 0.50 0.20 0.05 0.02
The expected weekly radio sales :
Σ(X) * p(x) : (0*0.03) + (1*0.20) + (2*0.50) + (3*0.20) + (4*0.05) + (5* 0.02) = 2.1

Answer:
7650 W-h
Step-by-step explanation:
1 day = 24 hrs
4 days and 6 hours = 4(24) + 6 = 102 hours
given
24 hrs (i.e 1 day) ------> consumes 1800 W-h
1 hour ------> consumes 1800/ 24 = 75 W-h
102 hrs (i.e 4 days 6 hrs) = 75 W-h x 102 = 7650 W-h
