40 minutes is not a full hour so you need to convert this to hours
40 minutes / 60 minutes = 2/3 of an hour
So a car driving at the rate of 34 2/3 mph will go
34 2/3 * 2/3 = Miles in 40 minutes
40 * (4/9) = ?or
160/9 = ? or
17 7/9 Miles
Answer:
Step-by-step explanation:
At the beginning, the jar contains the following beans:
5 purple
6 yellow
8 green
5 orange
Therefore, the total number of jellybeans in the jar tha beginning is:
The number of yellow beans at the beginning is
Therefore, the of selecting a yellow jellybean at the beginning is
After selecting this yellow bean, the yellow bean it is replaced in the jar, so the number of total beans is still n = 24.
And the number of purple beans inside is
So, the probability of selecting a purple bean at the 2nd attempt is
Therefore, the combined probability of selecting a yellow jellybean followed by a purple one is
