Answer:
495 combinations of 4 students can be selected.
Step-by-step explanation:
The order of the students in the sample is not important. So we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
How many combination of random samples of 4 students can be selected?
4 from a set of 12. So
495 combinations of 4 students can be selected.
<h2>Percent of speed the machine increase is 20%</h2>
<h2>Given that;`</h2>
Number of ice cream produced before = 45
Number of ice cream produced after = 54
<h2>Find:</h2>
Percent of speed the machine increase
<h2>Computation:</h2>
Percent of speed the machine increase = [Number of ice cream produced after - Number of ice cream produced before] / Number of ice cream produced before
Percent of speed the machine increase = [(54 - 45) / 45]100
Percent of speed the machine increase = [9 / 45]100
Percent of speed the machine increase = 20%

Answer:
Step-by-step explanation:
<u>Given function:</u>
- c(x) = 400 + 25x
- where x is the number of complete video games.
