<span>If set X is made up of the possible ways five students, represented by A, B, C, D, and E, can be formed into groups of three, then the set X consists of such triples {ABC, ABD, ABE, ACD, ACE, ADE, BCD, BCE, BDE, CDE} (note that triple ABC is the same as triple ACB, or BCA, or BAC, or CAB, or CBA). The set X totally contains 10 elements (triples). The first statement is true.

<span>If set
Y is made up of the possible ways five students can be formed into
groups of three if student A must be in all possible groups, then </span><span>the set Y consists of such triples {ABC, ABD, ABE, ACD, ACE, ADE} and contains 6 elements. The second statement is also true.
</span>
<span>If person E must be in each group, then there can be only one group is false statement, because you can see from the set X that triples which contains E are 6.
</span>
<span>There are three ways to form a group if persons A and C must be in it. This statement is true and these groups are ABC, ACD, ACE.</span>
The slope is 1, because the slope form is:
Where the m is the slope. Here, m=1.
The answer is 25, 25 x 8% is 2
Answer:
If 6 machines make 6 wheels in 6 minutes, that means each of the machines must make 1 wheel in 6 minutes. If you now consider 30 machines, and we know each of these 30 machines makes 1 wheel in 6 minutes, that means all 30 machines will make 30 wheels in 6 minutes.
