Answer:

Step-by-step explanation:

Factoring an expression is the process of undoing the multiplication.

Assume you have a function f(x):

$f(x)=x^2+2x-48$

This can be factored:

$f(x)=(x+8)(x-6)$

Using multiplication and the distributive property, you arrive back to:

$f(x)=x^2+2x-48$

Then you can see clearly that all we've done is reverse the multiplication.

Two events, A and B, are disjoint. What is the probability that both A and B will occur at the same time?

solniwko [45]

ANSWER

$P(A\cap B)=0$

EXPLANATION

If the two events are disjoint, then they are mutually exclusive.

This means that their intersection is zero.

Therefore

$n(A\cap B)=0$

This implies that,

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

$P(A\cap B)= \frac{0}{n(U)} = 0$

The probability that the two events will occur together is 0, which means an impossibility.

If an increase in one variable causes a decrease in another variable, there is A. a negative relationship. B. a dependent relat

Lunna [17]

Answer: Option 'A' is correct.

Step-by-step explanation:

Since we have given a situation that

If an increase in one variable causes a decrease in another variable,

Then, there is inverse relationship.

When one variable is increased whereas other variable falls.

There will be inverse relationship.

Since inverse relation has negative relation.

Then, there is a negative relationship.

Hence, Option 'A' is correct.
