The number divided by -4 to get 64 was -256
She started with 81 baseball cards.
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
Answer: 399=300+90+9
-45=0+40+5
300+130+14=414
Step-by-step explanation:
Expanded form is a way to write numbers by showing the value of each digit.
