Answer:

Independent.

Step-by-step explanation:

Independent events:

Two events, A and B, are said to be independent if the probability of both happening is the same as the multiplication of the probabilities of each happening, that is:

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

Thus, P(A and B)=P(A)•P(B) is used when two events are independent.

If AD is the altitude of BC, what is the slope of AD?

koban [17]

Answer:

Step-by-step explanation:

First, find the slope of BC :

⇒ m (BC) = -1 - 5 / -3 - 5

⇒ m (BC) = -6/-8

⇒ m (BC) = <u>3/4</u>

Now, since AD is the altitude of BC, we can say the altitude is perpendicular to BC.

Hence, the slope of a perpendicular line is equal to the negative reciprocal of the original line.

⇒ m (AD) = - (1/m(BC))

⇒ m (AD) = - (1/(3/4))

⇒ m (AD) = -4/3

0.008 divided by 0.62

AURORKA [14]

Answer:

Division states the operation that is opposite of multiplication.

Simplify: 0.008 divide by 0.62.

Symbol of divide is, $\div$

then;

$0.008 \div 0.62$

By definition of division;

$0.008 \times \frac{1}{0.62}$

$\frac{8}{1000} \times \frac{100}{62}= \frac{800}{62000} = \frac{8}{620} =0.0129032258$

Therefore, 0.008 divide by 0.62 we get 0.0129032258
