Answer:
Blank 1: 40
Blank 2: 10
Step-by-step explanation:
You can start by representing the speed of the water as x and the speed of the dolphin as y, and writing an equation.
y+x=50
y-x=30
Adding these two equations together, you get:
2y=80
y=40 for the speed of the dolphin in still water. Now, you an use one of the previous equations to find the speed of the current.
40-x=30
x=10

.3 = 3/10
.5 = 1/2
.05 = 1/20
.25 = 1/4
It is c because i believe so
The events are mutually exclusive, because your primary method can't be both a driving a car or taking a bus.
Since they are exclusive, the probability of the "or" clause is the sum of the probabilities:
Since a person primarily takes a bus with probability 0.32, the opposite happens with probability
