Answer:
$78
Step-by-step explanation:
to find 60% of 130 multiply 130 by 0.6
this gives you 78 dollars
The answer is c I hope that helps
Let the speed of the current equal c
and the speed of the boat in still water equal b.
b + c = 1.5 (b - c)
b + c = 1.5b - 1.5c
0.5b = 2.5c
b = 5c
The speed of the current is 1.5 mph so
b = 5 * 1.5 = 7.5 mph
The given MGF is that for a random variable following a Poisson distribution with parameter
.
This means
, and
has PMF
So, the desired probability is
This is equivalent to
1. x(2x^2-x+4)
2.-3(y-1)(y+2)
3.-(11w^2+18w-1)
