Answer:
f*2.5 + 40 = 100
Step-by-step explanation:
f*2.5 + 40 = 100
f = (100 - 40) / 2.5
f = 24
Given:
The number of tickets = 1000
Mathew buys a single ticket for $8
Winning price = $800
To find:
The expected earning per ticket.
Solution:
It is given that the total number of tickets is 1000. So, the probability of winning is:

The probability of losing is:

The expected earning per ticket is:






Therefore, the expected earning per ticket is -7.192. Here, negative sign means loss of $7.192.
Answer:
20.
Step-by-step explanation:
Assign variables. The numbers acan be 2x, 3x and 4x. Then, LCM of 2x, 3x and 4x is 12x
12x = 240
(240/12) = x = 20
The HCF of 2x, 3x, and 4x is 20. (Because x is the highest common factor.)
