The sale reduces the original price of the backpack, this reduces the mean, median and mode of the prices.
What is mean, median and mode?The measurements of central tendency are the mean, median, and mode. The means of a group of numbers is their average. The value that is in the middle of a group of numbers is known as the median. The number that appears most frequently out of a group of numbers is called the mode.
In a scale all the items are at a discounted rate this decreases the prices of the commodity thus decreasing the mean, median and mode of the prices.

Jordan has 8 coins in his pocket. They are a combination of dimes and quarters. If they total to $1.25, how many of each coin does he have
Answer:
q=quarters, d=dimes
q+d=8
.25q+.1d=1.25
Let's set the first equation to equal d.
d=8-q
.25q+.1(8-q)=1.25
Distribute.
.25q+.8-.1q=1.25
Combine Like Terms
.15q+.8=1.25
Subtract .8
.15q=.45
Divide by .15
q=3
Now, let's solve for d in the first equation.
d+3=8
Subtract 3, and you get d=5
So, there are 5 dimes and 3 quarters in Maribel's pocket.
Check: .25(3)+.1(5)=1.25
.75+.5=1.25
1.25=1.25 which is true.
Pls mark me as brainliest!Jordan has 3 quarters and 5 dimes in his pocket that total to $1.25.
Explanation:Let's assume Jordan has x number of quarters and 8 - x number of dimes in his pocket.
Each quarter is worth 25 cents, so the value of the quarters is 25x cents.
Each dime is worth 10 cents, so the value of the dimes is 10(8-x) cents.
The sum of the values of the quarters and dimes should be equal to $1.25, which is 125 cents. So, we can set up the equation: 25x + 10(8-x) = 125.
Simplifying the equation, we get 25x + 80 - 10x = 125. Combining like terms, 15x + 80 = 125. Subtracting 80 from both sides, 15x = 45. Finally, dividing both sides by 15, we find x = 3.
Therefore, Jordan has 3 quarters and 8 - 3 = 5 dimes in his pocket.

Three softball players discussed their batting averages after a game.
................Probability
Player 1: four sevenths
Player 2: five eighths
Player 3: three sixths
By comparing the probabilities and interpreting the likelihood, which statement is true?
A. Player 1 is more likely to hit the ball than Player 2 because P(Player 1) > P(Player 2)
B. Player 2 is more likely to hit the ball than Player 1 because P(Player 2) > P(Player 1)
C. Player 3 is more likely to hit the ball than Player 1 because P(Player 3) > P(Player 1)
D. Player 3 is more likely to hit the ball than Player 2 because P(Player 3) > P(Player 2)
Answer:
B. Player 2 is more likely to hit the ball than Player 1 because P(Player 2) > P(Player 1)
Step-by-step explanation:
This statement is true because the probability of Player 2, which is five eighths, is greater than the probability of Player 1, which is four sevenths. It is important to note that in order to compare the probabilities, it is necessary to convert the fractions to a common denominator. In this case, the common denominator is 56, then we can say that P(Player 2) = 35/56 and P(Player 1) = 28/56. Since 35/56 > 28/56, it is more likely that Player 2 will hit the ball than player 1.
Answer: B: Player 2 is more likely to hit the ball than Player 1 because P(Player 2) > P(Player 1)

What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The line has a slope of 1. Then the equation of the line is given as,

Last time it said 14 was wrong, is 14.1 correct?
Quadrilateral GHIJ is similar to quadrilateral KLMN find the measure of side MN
Answer: I believe 14.1 should be correct
Step-by-step explanation:
Given that we know one side length is 52 and the other is 21, we can use these values to create a scale.
52/21 = 2.4761, so we know that all sides will decrease by a scale of this value.
Given that, we can find the length of the MN. 35/2.4761 = 14.135
The question asks to round to the nearest tenth, so the answer should be 14.1. hope this helps!

Find the distance between the two points (5, -4) and (3 , 6). Give an exact answer in terms of a square root.
Answer:
√104.
Step-by-step explanation:
To find the distance between two points (x1, y1) and (x2, y2) in a coordinate plane, we can use the distance formula:
d = √((x2 - x1)² + (y2 - y1)²)
So, for the given points (5, -4) and (3, 6), the distance is:
d = √((3 - 5)² + (6 - (-4))²)
d = √((-2)² + (10)²)
d = √(4 + 100)
d = √104
Therefore, the distance between the two points (5, -4) and (3, 6) is √104.

The lengths of the legs of a right triangle are 7 in. and 2 in.
What is the length of the hypotenuse?
Enter your answer rounded to the nearest tenth
Answer: To find the length of the hypotenuse of a right triangle, we can use the Pythagorean theorem, which states that the square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the lengths of the other two sides. The theorem is written as c² = a² + b², where c is the length of the hypotenuse and a and b are the lengths of the other two sides.
In this problem, we are given that the lengths of the legs of the right triangle are 7 inches and 2 inches. We can substitute these values into the Pythagorean theorem and solve for c, the length of the hypotenuse.
So, we have c² = 7² + 2².
So, c² = 49 + 4
So, c² = 53
Now, we can take the square root of both sides of the equation, since c² = 53, we can say c = √53
To round to the nearest tenth, we look at the digit in the thousandths place (the 3rd digit after the decimal point). Since 3 is greater than or equal to 5, we round up, so c = 7.28, so the hypotenuse is 7.28 inches.

⠀
Alec's parents give him x dollars per month for his allowance. However, since his birthday is in February, he gets an extra 20% bonus that month. The allowance in February can be represented by the expression x + 0.2x because Alec will get the regular allowance of x dollars plus an extra 20% bonus which is equal to 0.2x dollars.
x + 0.2x = Alec's allowance in February
The expression 1.2x is not correct because it represents Alec's allowance multiplied by 1.2 which is not the same as the allowance plus the bonus.
So the correct answer is x + 0.2x.
2 irrational numbers that add up to 2
Answer:
An example of two irrational numbers that add up to 2 are √2 and √2 - 2.
√2 is an irrational number as it cannot be expressed as a ratio of two integers.
√2 - 2 is also an irrational number as it is the difference of two irrational numbers.
Both √2 and √2 - 2 are irrational numbers and √2 + (√2 - 2) = √2 + √2 - 2 = 2
So, √2 and √2 - 2 are two irrational numbers that add up to 2.

equation:
Find the slope and y-intercept of the function's graph, and find the equation for the function.
Answer:
The slope is -1
The y-intercept is -8
The equation is y = -x -8
Step-by-step explanation:
The slope is the change in y over the change in x. As the y is decreasing by 1. The x is increasing by 1
-1/1 = -1
The slope is -1.
The y-intercept is the y value when the x value is 0. When x = 0, y = -8
The y-intercept is -8.
y = mx + b
y = -1x - 8 I don't nee the 1 so I am going to write it without it.
y = -x - 8
