Answer:
1/4
Step-by-step explanation:
The probability of getting a heads is 1/2
The probability of getting an odd number
1,3,5
----------- = 3/6 = 1/2
1,2,3,4,5,6
Since they are independent events, we multiply the probabilities
1/2 * 1/2 = 1/4
Answer
Find out the the rate of the boat in still water.
To proof
let us assume that the speed of the boat in the still water = u
let us assume that the speed of the current = v
Formula

As given
18 miles downstream for 3 hours
Now for the downstream

u + v = 6
now for the upstream
As given
the trip back against the current takes 6 hours

u-v = 3
Than the two equation becomes
u + v = 6 and u - v = 3
add both the above equation
we get
2u = 9
u = 4.5miles per hour
put this in the u - v = 3
4.5 -v = 3
v =1.5 miles per hour
The rate of the boat in the still water is 4.5miles per hour .
Hence proved
Answer:
The answer is y=-x+4 and y=-3x+2
Step-by-step explanation:
When doing something like this you want to make sure both sides are the same, so turn 7/4 into a percent. 7/4 equals 175, therefore they’re equal to each other.
