Let's build the equation counting how many x's and 1's are there on each side.

On the left hand side we have 5x's and 8 1's, for a total of 5x+8

On the left hand side we have 3x's and 10 1's, for a total of 3x+10

So, the equation we want to solve is

5x+8 = 3x+10

Subtract 3x from both sides:

2x+8 = 10

Subtract 8 from both sides:

2x=2

Divide both sides by 2:

x=1

Answer:

The answers to the question above are given below:

Step-by-step explanation:

Question: What is a discrete probability​ distribution?

<u>Answer</u>

A discrete distribution is very important in data research as it shows in tabular form the probabilities that can be found in a list of distribution values and their individual probabilities in counted data. Usually, from the pool of distribution of numbers, the discrete distribution shows the probability of having countable numbers out of the pool.

<u>Question:</u> Choose the correct answer below. A. A discrete probability distribution exclusively lists probabilities. B. A discrete probability distribution lists each possible value a random variable can​ assume, together with its probability. C. A discrete probability distribution lists each possible value a random variable can assume. D. None of the above

The correct answer is: option B "discrete probability distribution lists each possible value a random variable can​ assume, together with its probability."

Question: What are the two conditions that determine a probability​ distribution?

<u>The correct answer is</u>:

1. Since each value may not be zero, each probability must include between 0 and 1.

2. When probabilities are totaled, it must give 1.

Help please it is simple
Ira Lisetskai [31]

Answer:

22 Inches Squared

Step-by-step explanation:

A=2(wl+hl+hw)

l = 1

w = 5

h = 1

A=2(5*1+1*1+1*5)\\A=2(5+1+5)\\A=2(11)\\A=22

The surface area should be 22in^2.

Elizabeth brought a box of donuts to share. There are two-dozen (24) donuts in the box, all identical in size, shape, and color.
pashok25 [27]

The probability of selecting two jelly-filled donuts in a row is 1/ 22

<h3>What is probability?</h3>

Probability is simply the chance that a given event will occur.

It is also the ratio of the number of outcomes in a set of equally likely outcomes that produce a given event to the total number of possible outcomes.

From the information given, we have that the donuts are:

  • 6 are jelly-filled
  • 10 are lemon-filled
  • 8 are custard-filled

Note that two jelly - filled donuts were taken without replacement

Probability( 2 jelly -filled donuts) = 6 / 24 × 4/ 22 = 24/ 24 × 22 = 1/ 22

Thus, the probability of selecting two jelly-filled donuts in a row is 1/ 22
