Step-by-step explanation:
(a) The probability of winning a 6/49 lottery is given by:
(b) The probability of winning a 6/53 lottery is given by:
(c) The probability of winning a 6/51 lottery is given by:
(d) The ratio between the probabilities of winning the 6/49 lottery and winning the 6/53 lottery is:
It is 1.6417 times more probable.
Yes they are. Given that a volume of a rectangular prism is V=l•w•h, we can plug them into an equation and compare them. I'll call the Right rectangular prism figure R and the oblique rectangular prism O
For Figure R, We know all the basic needs to find the volume. This means we can plug it in.
V=l•w•h
V=12•3•5
Now We can solve for V
V=12•15
V=180
The volume of the right rectangular prism is 180in^3
Now, For figure O.
V=9•4•5
V=9•20
V= 180.
With this in mind, We now can say that the volumes of both the rectangular prisms are the same.
Answer:
The length of the river on a map is
Step-by-step explanation:
we know that
The scale of the map is
That means
1 cm on a map is 5,000,000 cm on the actual
or
1 cm on a map is 50 km cm on the actual
so
using proportion
