Answer:
<h3>★ <u>11/30</u> is the right answer. ★</h3>
Step-by-step explanation:
- Number of male students who got 'A' in the test is 11
- Number of female students who got 'A' in the test is 19
- Total students who got 'A' in the test is 30
- Probability that the male student got an 'A' is P(A | male) = (Number of male students who got 'A' in the test)/(Number of total students who got 'A' in the test) = <em><u>11/30</u></em>
We find the average by adding up all the students and dividing them by the number of classes she has. 19 + 13 + 19 + 9 + 14 + 15 is 89, and that divided by 6 is approximately 14.8, rounded to the nearest tenth.

Answer:
The answer to your question is:
a) f(a) -2 = a² - 3
b) f(a - 2) = a² - 4a + 3
c) f(b + d) = b² + 2bd + d² - 1
Step-by-step explanation:
a. f(a) - 2 = (a)² - 1 - 2
f(a) -2 = a² - 3
b. f(a - 2) = (a - 2)² - 1
f(a - 2) = a² - 4a + 4 - 1
f(a - 2) = a² - 4a + 3
c. f(b + d) = (b + d)² - 1
f(b + d) = b² + 2bd + d² - 1
