Answer:
C
Step-by-step explanation:
Key in the expression is "s" that represents students going to the trip
The first part shows what the adventure park is going to charge, a group day charge of $300 and $30 more for the students taking the ropes course
300+30*s
The second being the amount the class can get, $500 the have in the account and $25 per student in tickets they have to sell
500+25s
The result of this subtraction is the money they need to raise to complete
C: The expression shows how much money the freshman class may need to raise in order to afford the event
Answer:
- 0.80
- 0.289
- 0.20
- 0.711
Step-by-step explanation:
Given:

The rule of total probability states that:

Compute the individual probabilities as follows:




Conditional probability of an event A given B is:

- Compute the value of
:

- Compute the value of


- Compute the value of

- Compute the value of

Using the information from the question, one can construct two equations:

... (1)

... (2)
by substituting (1) into (2) to find x


\frac{5}{4z} = \frac{1}{4}



⇒ z = 5
By substituting value of z into (1)
⇒ 4 (5) = x
⇒ x = 20
Thus the two numbers are 5 & 20
2/5 + 1/6 = 12+5/30 = 17/30
30/30 is the whole book so, 30/30 - 17/30 = 13/30
Sam had to read 13/30 of the book.
Is the question what is 75% of 12? If it is, 75% of 12 is 9.
