I think that this is a combination problem. From the given, the 8 students are taken 3 at a time. This can be solved through using the formula of combination which is C(n,r) = n!/(n-r)!r!. In this case, n is 8 while r is 3. Hence, upon substitution of the values, we have
C(8,3) = 8!/(8-3)!3!
C(8,3) = 56
There are 56 3-person teams that can be formed from the 8 students.
Can you show what Cody put so I can help you
A system of equations is:
B )
x + y = 375
x = 2 y - 60
We will solve this system:
2 y - 60 + y = 375
3 y = 435
y = 435 : 3
y = 145
x = 375 - 145
x = 230
Allan`s score was 230 and Dave`s score was 145.
The expression without using absolute value is 2z - 11
<h3>Absolute value of a function</h3>
Given the expression with absolute value expressed as:
lz-6l-lz-5l
Since absolute function can both be negative or positive, hence;
lz-6l-lz-5l = z - 6 - -(z - 5)
lz-6l-lz-5l = z-6-(-z+5)
lz-6l-lz-5l = z - 6 + z - 5
lz-6l-lz-5l = 2z - 11
Hence the expression without using absolute value is 2z - 11
