Answer:

No it is not the sides of right angled triangle.

Step-by-step explanation:

IF a²+b²=c² then the triangle is right

3²+3²=32²

9+9=1024

18=1024

Step-by-step explanation:

Although two sides are equal, the 32 is simply too big for it to be a triangle.

Use the zero product property to find the solutions to the equation x^2+x-30=12

lukranit [14]

Answer:

Due to there being no negatives in this equation, you can pretty much just eliminate the first 3 answers.

However in working out, here is what I did.

x^2 + x - 30 = 12 (+30)

= x^2 + x = 42

Then you can conclude that the answer is D, due to 6 x 6 = 36, plus 7 equaling 42.

If events A and B are independent, what must be true?A.) P(AB) = P(B)

anygoal [31]

Answer:

B.) P(A/B) = P(A)

Step-by-step explanation:

If two events, A and B are independent:

We have that:

$P(A \cap B) = P(A)P(B)$

Conditional Probability

We use the conditional probability formula to solve this question. It is

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

Since they are independent:

$P(A \cap B) = P(A)P(B)$

Then

$P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{P(A)P(B)}{P(A)} = P(B)$

$P(B|A) = P(B)$ , or either:

$P(A|B) = P(A)$ , and thus, the correct answer is given by option B.
