The question, “How many ways can 4 students be chosen from a class of 30 students?”, is a(n) _____.
2 answers:
Answer: Option 'A' is correct.
Step-by-step explanation:
Since we have given that
Total students in a class = 30
Number of students is to be chosen = 4
So, we will use Combination :
<u>As Combination is the collection of the object irrespective of any arrangement.</u>
So, Number of ways to choose 4 students among the 30 students is given by
Hence, Combination is the required answer.
Therefore, Option 'A' is correct.

Answer:
Plot the following points on the graph
, (0, 1), (1, 2), (2, 4), (3, 8)
Step-by-step explanation:
If the equation for the line is y = , whatever the power/exponent "x" equals, then y is equal to however many times 2 is multiplied by x.
For example, if our domain is {-1, 0, 1 , 2, 3}
then we would plug in each x value into the exponent to find the y-value in order to plot the points to solve the problem.
If x = -1, then y = 1/2. **If there is an a negative exponent it would get turned into a positive fraction with the denominator as the positive version of that number.
If x = 0, then y = 1
**When the exponent is 0, the number automatically equals 1.
If x = 1, then y = 2.
If x = 2, then y = 4
If x = 3, then y = 8
So you would plot the following coordinates on the graph:
(0, 1)
(1, 2)
(2, 4)
(3, 8)
