What is 0.25 kilometers expressed in centimeters?

Agata [3.3K]

Knowing the fact:
1 km = 1000m
1 m = 100cm

We can calculate:
0.25 km = 0.25 * 1000m = 250m = 250 * 100cm = 25 000cm

First, decide whether the distribution is a discrete probability distribution, then select the reason for making this decision.

Lyrx [107]

It is not a <u>probability distribution</u>, as the sum of the probabilities is more than 1, thus, the correct option is No, considering that:

c) Since the sum of the probabilities is not equal to 1.

-----------------------------------------

For the sequence $(x, P(X = x))$ representing a probability distribution, it is needed that:

All probabilities are between 0 and 1, that is, for all values of x, $0 \leq P(X = x) \leq 1$ .
The sum of all probabilities is 1, that is: $\sum_{i = 1}^n P(x_i) = 1$

In this problem, the sum of the probabilities is:

$\sum_{i = 1}^n P(x_i) = 0.39 + 0.69 + 0.12 = 1.20$

<u>Sum is not 1,</u> thus it is not a probability distribution, and the correct option is:

c) Since the sum of the probabilities is not equal to 1.

Rhea is solving a math puzzle. To find the solution of the puzzle, she must find the product of two numbers. The first number is

Dmitriy789 [7]

Answer:

P(x) = 2x² + 74x + 644

Step-by-step explanation:

The first number is x + 23.

The second number is:

2(x + 23) − 18

2x + 46 − 18

2x + 28

The product is:

P(x) = (x + 23) (2x + 28)

P(x) = 2x² + 28x + 46x + 644

P(x) = 2x² + 74x + 644

1. What is the sum of the probabilities in a discrete probability distribution? Why?

ycow [4]

Answer:

Sum of probabilities in a discrete probability distribution is 1.

Step-by-step explanation:

The sum of the probabilities in a probability distribution is always 1.

A probability distribution is a collection of probabilities that defines the likelihood of observing all of the various outcomes of an event or experiment. Based on this definition, a probability distribution has two important properties that are always true:

Each probability in the distribution must be of a value between 0 and 1.

The sum of all the probabilities in the distribution must be equal to 1.
