There are 25 students that would like to go on a field trip, but only 18 may go. How many different combinations of students cou
Naya [18.7K]

480700. The different combinations of students that could go on the trip with a total of 25 student, but only 18 may go, is 480700.

The key to solve this problem is using the combination formula nC_{r}=\frac{n!}{r!(n-r)!}. This mean the number of ways to choose a sample of r elements from a set of n distinct objects where order does not matter and replacements are not allowed.

The total of students is n and the only that 18 students may go is r:

25C_{18}=\frac{25!}{18!(7!)}=480700

<h3>Answer:  6/25</h3>

======================================================

Explanation:

The table shows the spinner lands on "4" exactly 12 times out of the 50 total.

12/50 = (2*6)/(2*25) = 6/25

In decimal form that is 6/25 = 0.24 which converts to 24%

Evaluate 4 2/3-(-1 4/5)
Blababa [14]
Find a common denominator by multiplying the two different denominators by each other to get 15. 2/3 then becomes 10/15 and 4/5 becomes 12/15.

You now have 4 and 10/15 minus negative 1 and 12/15. Subtracting a negative number results in addition, so it's 4 and 10/15 PLUS 1 and 12/15. You get 5 and 22/15, which becomes 6 and 7/15.

The answer is C.

The value of w varies directly with z. If z = 4, then w = 12. What is the value
IrinaVladis [17]

Answer:

18

Step-by-step explanation:

w varies directly with z, let k be the constant of proportionality, hence this can be represented by the equation:

w = kz

When z = 4, w = 12, hence we need to find the value of the constant of proportionality, substituting:

12 = 4k

Dividing both sides by 4:

12/4 = 4k/4

k = 3

Therefore the equation becomes:

w = 3z

The value of w when z = 6 is given as:

w = 3(6)

w = 18
