Step-by-step explanation:
Option C
2100 different committees that can be formed from 5 teachers and 10 students
<em><u>Solution:</u></em>
A school committee consists of 2 teachers and 4 students
The number of different committees that can be formed from 5 teachers and 10 students is to be found
This is a combination problem
A combination is a selection of all or part of a set of objects, without regard to the order in which objects are selected
<em><u>The formula to calculate combinations is:</u></em>
where n represents the number of items, and r represents the number of items being chosen at a time
Here we have to choose 2 teacher from 5 teacher and 4 student from 10 student
Hence we get,
Number of committees =
To get the factorial of a number n the given formula is used,
Therefore,
Thus 2100 different committees that can be formed from 5 teachers and 10 students
Your problem is giving you d in terms of t, meaning that it is asking if we replace t with 11, what would d be?
When a number is right in front of a variable, they are being multiplied
So if t is 11, and the problem shows 11t, we replace the t with 11 and put parentheses around it
d = -20 + 11t
d = -20 + 11(11)
d = -20 + 121
d = 101
And there you have it! Your final answer is d = 101!
Practice pre-algebra and plugging in numbers into equations! Having mastery over the basic math functions and rules, as well as Order Of Operations, makes all of this so much easier!
I recommend that you watch Khan Academy videos and practice problems on there! It is a great resource! What you are learning would most likely fall under pre-algebra!
