According to the general equation for conditional probability, if P(A, B) =4/7

Neko [114]

Answer:

$P(A|B) = \frac{32}{49}$

Step-by-step explanation:

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

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

In which

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

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

P(B) is the probability of B happening.

We have that:

$P(A \cap B) = \frac{4}{7}, P(B) = \frac{7}{8}$

$P(A|B) = \frac{P(A \cap B)}{P(B)} = \frac{\frac{4}{7}}{\frac{7}{8}} = \frac{4}{7}*\frac{8}{7} = \frac{32}{49}$

Then

$P(A|B) = \frac{32}{49}$

Answer:

$m\angle 1=95^{\circ}$

Step-by-step explanation:

If we drew an auxiliary line parallel to line $p$ and line $q$ that intersects the vertex of $\angle 1$ , we would form three angles, one of them being

The largest of these angles corresponds with the angle marked as $148^{\circ}$ .

The angle on the bottom right corresponds with the angle next to the one marked as $63^{\circ}$ . Therefore, its measure is $180-63=117^{\circ}$ .

Since there are $360^{\circ}$ in a circle, we can now write the following equation:

$m\angle 1+117+148=360,\\m\angle 1=\fbox{$95^{\circ}\checkmark$}$ .

Rainbow [258]

Answer:

Function B has the greater rate of change

Step-by-step explanation:

Function A has a slope of 1/3

Function B has a slope of 1/2

When comparing slopes, the higher value has the greater rate of change

1/2 > 1/3
