Answer:
2/3
Step-by-step explanation:
A = Student studying Math
B = Student studying Science
P(B|A) = P(A and B) ÷ P(A).
P(B|A) means the probability of event B given event A.
Given :
P(A and B) = 0.40.
Also P(A) = 0.60.
P(B|A) = 0.40 ÷ 0.60 = 2 ÷ 3.
So, the answer is 2/3.
√72 = √4 * √18 = 2√18. Therefore her answer is incorrect.
√72 = √4 * √9 * √2 = 6√2.
Since √2 is approximately 1.41,
6 * 1.41 = 8.46 = 8.5 (nearest tenth).

Answer:
2 a^2 b (7 a^2 b^2 c + 9)
Step-by-step explanation:
Factor the following:
14 a^4 b^3 c + 18 a^2 b
Hint: | Factor common terms out of 14 a^4 b^3 c + 18 a^2 b.
Factor 2 a^2 b out of 14 a^4 b^3 c + 18 a^2 b:
Answer: 2 a^2 b (7 a^2 b^2 c + 9)
