Answer:
2.54 miles/hr
2.04 miles/hr
Step-by-step explanation:
<u>Given: </u> Distance between the two towns = 1100 miles
Difference between speeds =
miles/hr
Total time when they meet = 240 hours
<u>To find:</u>
Let distance traveled by first group =
miles.
Now, the distance traveled by second group = (1100-
) miles/hr
The relation between Speed, Time and Distance is given as:

Let speed of first group = 

Let speed of second group = 

As per question,
=
+ 

Now,

Putting value of
:

Similarly, putting value of
in
:

Answer:
- 3.027
Step-by-step explanation:
First price = 10000 ; second price = 700
Number of tickets sold = 11000
Ticket cost = $4
Probability that a ticket wins grand price = 1 / 11000
Probability that a ticket wins second price = 1 / 11000
X ____ 10000 _____ 700
P(x) ___ 1 / 11000 ___ 1/11000
Expected winning for a ticket buyer :
E(X) = Σx*p(x)
E(X) = (1/11000 * 10000) + (1/11000 * 700) - ticket cost
E(X) = 0.9090909 + 0.0636363 - 4
E(X) = - 3.0272728
E(X) = - 3.027
