Answer:
Option A
Step-by-step explanation:
Dennis made an extra $245.00 for selling furniture. The extra $245.00 was 7% of the total value of the furniture he sold. What was the total value of the furniture Dennis sold?
245 = 0.07x
divide both sides by 0.07:
245/0.07 = 0.07x/0.07
x = $3,500

You and your friend are playing "Rock-Paper-Scissors." In this game, each of the two players chooses rock, paper, or scissors. Both players reveal their choice at the same time, and the winner is determined based on the choices. Rock beats scissors by smashing it, scissors beats paper by cutting it, and paper beats rock by covering it. If both players choose the same object, it is a tie. All the possible outcomes of the game are listed below. If we take outcomes 1,3,4,5,8,1,3,4,5,8,1, comma, 3, comma, 4, comma, 5, comma, 8, comma and 999 as a subset of the sample space, which of the statements below describe this subset?
As we already found, the probability of winning for any selection is 1/3 = 0.333.
What is probability?Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Probability = Number of favourable outcomes / Number of samples
a) Let's suppose that player 1 chooses rock, and the selection of player 2 can be thought of as random.
If player 2 randomly selects rock, the result of the game is a draw.
if player 2 randomly selects papers, player 1 loses.
if player 2 randomly selects scissors, player 1 win.
Then we have 3 options with the same probability, that will be:
1/3
This is, the probability of winning is equal to the quotient between the number of outcomes that make player one win (1, in this case, scissors) and the total number of outcomes (3) = 1/3
the probability of a draw is equal to the quotient between the number of outcomes that make a draw (1, in this case, rock) and the total number of outcomes (3) = 1/3
The probability of losing is equal to the quotient between the number of outcomes that make player one lose (1, in this case, paper) and the total number of outcomes (3) = 1/3
The complete question is given below.
2. Almost everyone has played the rock-paper-scissors game at some point. Two players face each
other and, at the count of 3, make a fist (rock), an extended hand, palm side down (paper), or a
"V" with the index finger and middle fingers (scissors). The winner is determined by these rules:
rock smashes scissors, paper covers rock, and scissors cut paper. If both players choose the
same object, then the game is a tie. Suppose that Player 1 and Player 2 are both equally likely to
Choose rock, paper, or scissors.
a) Give a probability model for this change process.
b) Find the probability that Player 1 wins the game on the first throw.

A computer password is required to be 7 characters long. How many passwords are possible if the password requires 1 letter(s) followed by 6 digits (numbers 0-9), where no repetition of any letter or digit is allowed?.
A computer password is required to be 7 characters long.
Note the requirements:
Repetition of letter or digit is not allowed.
The order of the letters and digits matters.
Because of that, permutation would be the most suitable way to count the number of possibilities.
There are [tex]P(26,3) = \frac{26!}{(26-3)!} = 26x25x24 = 15,600[/tex] ways to arrange three out of distinct letters (without replacement.)
Similarly, there are [tex]P(10,4) = \frac{10!}{(10-4)!} = 10x9x8x7 = 5,040[/tex] ways to arrange four out of distinct numbers (also without replacement.)
Therefore, there are 15,600 possibilities for the three-letter section of this password, and 5,040 possibilities for the four-digit section. What if these two parts are combined?
Consider: if the first three letters of the password were fixed, then there would be 5,040 possibilities. However, if any of the first three letters was changed, the result would be another 5,040 possibilities, all of which are different from the previous 5,400 possibilities. These two three-letter sections along will give 2 x 5,400 possibilities. Since there are 15,600 three-letter sections like that, there would be 15,600 x 5,400 = 78,624,000 possible passwords in total. That gives the number of possible passwords that satisfy these requirements.

cars a and b leave town at the same time. car a heads due south at rate of 80 km/hr and car b heads due west at a rate of 60 km/hr. how far is the distance between the cars increasing after three hours?
The distance between the two cars after three hours is 300 km
Cars a and b leave town at the same time.
The speed of the car that went to south = 80 km/hour
The total distance traveled in three hours = 80 × 3
= 240 km
The speed of the car that went to the west = 60 km/hour
The total distance traveled in three hours = 60 × 3
= 180 km
The distance between the two car is the hypotenuse of the right triangle
The distance between the two cars after three hours = [tex]\sqrt{240^2+180^2}[/tex]
= [tex]\sqrt{57600+32400}[/tex]

The answer will be, at least as small as that provided by the sample using p-value.
What is the p-value?
Under the premise that the null hypothesis is true, the p-value in null-hypothesis significance testing represents the likelihood of receiving test findings that are at least as extreme as the result actually observed. A severe observed outcome would be highly improbable under the null hypothesis, according to a very small p-value. In academic papers of many quantitative fields, reporting the p-values of statistical tests is standard practice. Misuse of p-value is common and has been a big concern in metascience due to its difficult-to-understand precise meaning.
The probability that a population parameter in a particular statistical model will be less than a given value when the null hypothesis is true is known as the p-value,

After solving, the value of x is 8 and the value of y is 9.
In the given question,
We have to find the value of x and y.
It is also given that the given quadrilateral is a parallelogram.
Since the given quadrilateral is a parallelogram so the opposite sides and opposite angles are equal to each other.
So 4x−17=2x−1......................(1)
5y−13=3y+5...............(2)
Simplifying equation 1 to find the value of x
4x−17=2x−1
Add 17 on both side
4x−17+17=2x−1+17

This means that the answer is D.
What is probability in math?
In everyday speech, the term "probability" refers to the likelihood that a specific event (or set of events) will take place, expressed as a number between 0 and 100% or as a linear scale from 0 (impossibility) to 1 (certainty). Statistics is the study of occurrences that follow a probability distribution.
How do you find the probability?The probability is calculated by dividing the total number of possible outcomes by the number of possible ways the event could occur. Probability and odds are two distinct ideas. Odds are calculated by dividing the likelihood of an event by the likelihood that it won't.
According to the given question:-
Even though there aren't any actual options for this question, figuring out the right response should be simple. The quantity of numbers that will be listed is the "probability of success" that is being discussed here.

The major thing that Ryan should be worried about is the C) high annual depreciation.
What financial choice should be made?Normally, when we buy cars they have so much value but when the cars start being used more often, they tend to depreciate in value due to wear and tear and second value of the product. This tells us that when a car is driven for more miles in a year, it will depreciate greatly.
We are told that Ryan plans to drive about 40 miles to work and back everyday which means that in a year he would have driven thousands of miles. This will lead to a high depreciation.

The formula for the final cost, in terms of the original price y, is:
c(y) = y*(0.88)*(1.03)
How to find an expression for the final cost of the DVD?
Let's define y as the original price of the DVD.
We first apply a discount of the 12% of the price, so the new cost will be:
c(y) = y*(1 - 12%/100%)
c(y) = y*(1 - 0.12)
Then we apply a tax of the 3%, this in increase, then we can write this as:
c(y) = y*(1 - 0.12)*(1 + 3%/100%)
c(y) = y*(1 - 0.12)*(1 + 0.03)
c(y) = y*(0.88)*(1.03)
