Answer:

Vertically opposite angles.

Step-by-step explanation:

A line is a one-dimensional figure having no thickness and extends infinitely in both the directions.

Intersecting lines are the lines which intersect at one point.

Parallel lines which do not intersect at any point.

An angle is formed by two rays meeting at a common end point.

Vertically opposite angles are the angles formed opposite to one another at the intersection of two lines.

Vertically opposite angles are always equal.

9514 1404 393

Answer:

Step-by-step explanation:

Katherine will use a multiple of 1/2 pint to serve her guests. That is the number of pints she will serve will be 2 1/2 = 5/2 = 5×(1/2).

Katherine can serve a maximum of 5 guests with the ice cream she purchased.

We could look at the quotient of 2 2/3 = 8/3 and 1/2. It will be ...

(8/3)÷(1/2) = (8/3)×(2/1) = 16/3 = 5 1/3

The largest whole number in this value is 5, the number of guests Katherine can serve.

Assume a test for a disease has a probability 0.05 of incorrectly identifying an individual as infected (False Positive), and a

Nana76 [90]

Answer:

0.00002 = 0.002% probability of actually having the disease

Step-by-step explanation:

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.

In this question:

Event A: Positive test

Event B: Having the disease

Probability of having a positive test:

0.05 of 1 - 0.000001(false positive)

0.99 of 0.000001 positive. So

$P(A) = 0.05*(1 - 0.000001) + 0.99*0.000001 = 0.05000094$

Probability of a positive test and having the disease:

0.99 of 0.000001. So

$P(A \cap B) = 0.99*0.000001 = 9.9 \times 10^{-7}$

What is the probability of actually having the disease

$P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{9.9 \times 10^{-7}}{0.05000094} = 0.00002$

0.00002 = 0.002% probability of actually having the disease
