<span>Given
∠FHJ = 60°
</span><span>∠FGH = 28°
</span>∠FHG = 180 - ∠FHJ
∠FHG = 180 - 60
∠FHG = 120
∠HFG = 180 - (28 + 120)
∠HFG = 180 - 148
∠HFG = 32
Answer: 0.49
Step-by-step explanation:
The mean= E[x]=1/l= 7.5 min
l=1/7.5 =10/75=2/15
The exponential distribution's probability density function is looking like that:
F(x)= l*e^(-l*x) = 2/15*e^(-2*x/15)
P(0<x<5)= e^(-0*2/15)- e^(-5*2/15)=1- e^(-2/3)= approx 0.49
