Answer:
8/27
Step-by-step explanation:
<u><em>Given:</em></u>
<em>In a class of 27 students, 18 are female and 8 have an A in the class. There are 2 students who are female and have an A in the class.</em>
<u><em>To Find:</em></u>
<em> What is the probability that a student chosen randomly from the class has an A?</em>
<u><em>Solve:</em></u>
<em>Given:</em>
<em>Total : 27</em>
<em>Female : 18</em>
<em>A : 8</em>
<em>A Female : 2</em>
<em />
<em>Therefore,</em>
<em />
<em>8/27</em>

1. As x approaches 1, f(x) approaches 3-1, that is 2.
If a = 2 and b = 3, f(1) = 2(1)^2 + 3(1) = 5
So there is a 'jump' in values of x at x = 1. So its not continuous at x=1.
2. For continuity at x = 1, ax^2 + bx must = 2 that is when a + b = 2.
3. for continuity at x = 2 , ax^2 + bx must be = 0 that is when a*2^2 + 2b = 0
- that is 4a + 2b = 0.
4. we have system of equations:-
a + b = 2
4a + 2b = 0
this gives a = -2 and b = 4 So f(x) is continuous when a = -2 and b = 4.
The common unit to measure angles is called.... degree
