7 - 9w = - 29
Subtract 7 from both sides
- 9w = - 36
Divide by - 9 on both sides
w = 4
First, we need the probability of picking an odd number.
There are 5 cards in total, and 3 odd cards (3, 5, and 7).
That means that the probability that we'll draw an odd card would be
.
Then, we have 4 cards left, and 2 even cards (4 and 6), meaning that the probability that we draw an even card will be
or
.
To find the probability that these would happen in consecutive draws, we just multiply the probabilities together.
or 0.3.
To convert this into a percentage, we multiply the decimal by 100.
.
So the probability of picking an odd number and then picking an even number is 30%.
Hope this helps!
Answer:
2.22 km
Step-by-step explanation:
Assuming initially both were at the same point ...
Distance from Rico = 5.98 km.
Distance from Josh = 8.2 km in the same direction.
If they were going in the same direction, then the final distance between the two can be written as follows:
d = 8.2 - 5.98 = 2.22 km
After 20 minutes, Rico and Josh were 2.22 km away. of distance between them.
