A.) Probability of selecting two students and two faculty members from 20 students and 5 faculty volunteers = no of ways of selecting two students and two faculty members from 20 students and 5 faculty volunteers divided by the number of ways of selecting 4 people from 25 people = (20C2 x 5C2) / 25C5 = 1900 / 53130 = 0.036 = 3.58%
b.) Probability of selecting three students and one faculty members from 20
students and 5 faculty volunteers = no of ways of selecting three students
and one faculty members from 20 students and 5 faculty volunteers
divided by the number of ways of selecting 4 people from 25 people = (20C3 x 5C1) / 25C5 = 5700 / 53130 = 0.107 = 10.7%
Answer:
<h2>x = 3 and x = 4 → (3, 0) and (4, 0)</h2>
Step-by-step explanation:
Answer:
The solution to the system is (-2,6)
Step-by-step explanation:
I said the solution to the system is (-2,6) because that is where both lines cross, meaning that's the solution.
Hope this is hepful.
Answer:
the first one is a function! there are no repeated x values in a function
No, we cannot say <span>that there is no object with an order of rotational symmetry as 0.
For example:
</span><span>What do you think the rotational symmetry order of an alphabet "A" is?</span><span>
</span><span>The alphabet "A" has got rotational symmetry of order 1, which means </span>NO rotational symmetry is there for letter "A" because we can't rotate it.
