Fill in the blank. A​ _______ probability of an event is a probability obtained with knowledge that some other event has already occurred.

Answers

Answer:

A​ conditional probability of an event is a probability obtained with knowledge that some other event has already occurred.

Step-by-step explanation:

Conditional probability of an event (A) is a probability obtained with knowledge that some other event (B) has already occurred and is denoted as P(A|B).

It satisfies the following equation:

  • P(A|B)=P(A and B) / P(B)

where P(A and B) is the probability of A and B occurring together.

Conditional probability is applied in many areas of Bayesian statistics and machine learning.

Final answer:

The blank space should be filled with 'conditional'. A conditional probability of an event is a probability calculated with the knowledge that another event has already happened.

Explanation:

The blank space should be filled with 'conditional'. A conditional probability of an event is a probability obtained with knowledge that some other event has already occurred. Suppose you have events A and B from the same sample space. The conditional probability of event A given that event B has occurred, denoted as P(A|B), is computed as P(A and B) divided by P(B), where P(A and B) represents the probability that both events happen, and P(B) is the probability of B happening. This quantity is meaningful as long as P(B) is not zero.

Abed says he has written a system of two linear equations that has an infinite number of solutions. One of the equations of the system is y = 3x – 1. Which could be the other equation?

Answers

y = 3x + 23x – y = 23x – y = 1 3x + y = 1

The correct answer is:

Any equation that is a multiple of y=3x-1.

Explanation:

In order to graph as the same line, the equations must be the same.  This means that all pieces of the first equation must be multiplied by the same factor, or the equation must be rewritten.

Answer:

\large \boxed{\sf \ \ (x^2)/(x^4+1)=(1)/(7) \ \ }

Step-by-step explanation:

Hello,

We know that (let's assume that x is different from 0 as we cannot divide by 0)

   x+(1)/(x)=3

and we want to estimate

   (x^2)/(x^4+1)

Let's take the square.

9=3^2=(x+(1)/(x))^2=x^2+2\cdot x \cdot (1)/(x)+(1)/(x^2)=x^2+2+(1)/(x^2)=(x^4+1)/(x^2)+2

So, we can write

(x^4+1)/(x^2)=9-2=7 \n \n\n\text{*** let's take the inverse ***} \n \n(x^2)/(x^4+1)=(1)/(7)

Hope this helps.

If f(x) is the total cost, in dollars, of x candies, which of the following statements best describes the meaning of f(2) = 6? A. The total cost of 2 candies is $6.00./ B. The total cost of 6 candies is $2.00. / C. The total cost of 2 candies is $3.00. / D.The total cost of 3 candies is $2.00.

Answers

Since the cost is a function of the total number of candies (x), therefore the equation relates the total cost per amount of candies.

Since we have 2 candies therefore the correct statement should be that the total cost of 2 candies is $6.00

this statement is letter A of the given choices. 

Answer:

The total cost of 6 candies is $2.00.

Step-by-step explanation:

Given :  f(x) is the total cost, in dollars, of x candies,

To Find: Which of the following statements best describes the meaning of f(2) = 6?

Solution:

We are given f(2)=6

Since f(x) is the total cost, in dollars, of x candies.

So, 6 is the total cost of 2 candies.

Thus the total cost of 2 candies is $6.

Hence Option A is true.

The total cost of 6 candies is $2.00.
