Miss Valens withdrew $525 from her savings account over a period of 14 days. Which ratio represents the daily change in her account balance?
(multi choice picture below)
It says that she withdrew 525 dollars from a saving account over a total period of 14 days.
As this amount is debited from her account, so it would be a negative number in her passbook i.e. -525 dollars.
To find the average change in the account balance, we can divide the total amount withdrawn from the account by the total number of days.
Average change in account balance = [tex]\frac{debited \;amount}{total \;time \;period}[/tex] .
Average change = [tex]\frac{-525}{14}[/tex]
Hence, option A is correct i.e. [tex]\frac{-525}{14}[/tex].
PLEASE HELP!!!!!!!!!!! Kim wants to know if the number of words on a page in her math book is generally more than the number of words on a page in her poetry book. She takes a random sample of 25 pages in each book, then calculates the mean, median, and mean absolute deviation for the 25 samples of each book.
Book Mean Median Mean absolute deviation
Math 49.9 43 10.2
Poetry 41.5 42 1.1
Kim claims that because the mean number of words on each page in the math book is greater than the mean number of words on each page in the poetry book, the math book has more words per page. Based on the data, is this a valid inference? (5 points)
Yes, because the mean is larger in the math book
No, because the mean is larger in the math book
No, because there is a lot of variability in the math book data
Yes, because there is a lot of variability in the math book data
YOU WILL GET BRAINIEST
It's D, because the mean doesn't matter as much if it's only taken in a small variability. The mean was selected from 25 random pages in the book, that is why it is right.
Answer:
Yes, because the mean is larger in the math book.Step-by-step explanation:
According to Kim's calculations
The mean of the Math Book is 49.9, this means there are 49.9 per page.The mean of the Poetry Book is 41.5, which means there are 41.5 per page.Remember that a mean is defined as the quotient between the sum of all elements and the total number.
According to this calculations, the Math Book has more words per page, based on its greater mean.
Therefore, the right answer is the first choice.

Kelsey bought a circular rug that is 12 feet in diameter. The rug has a blue boarder and a red circular center that is 4 feet in diameter. What is the area of the blue boarder? Round to the nearest 10th place
Final answer:
To calculate the area of the blue border of the circular rug, subtract the area of the red center from the area of the entire rug. Using the area formula for a circle, the area of the blue border is approximately 100.5 square feet when rounded to the nearest tenth.
Explanation:
To find the area of the blue border of Kelsey's circular rug, we first need to calculate the area of the entire rug and then subtract the area of the red circular center. The diameter of the entire rug is 12 feet, which means its radius is 6 feet. Similarly, the diameter of the red center is 4 feet, giving it a radius of 2 feet. We use the formula for the area of a circle, A = πr^2, where A is the area and r is the radius.
First, we calculate the area of the entire rug with a radius of 6 feet:
Atotal = π * 6^2 = π * 36 = 36π square feet.
Next, we calculate the area of the red center with a radius of 2 feet:
Acenter = π * 2^2 = π * 4 = 4π square feet.
Now, we subtract the area of the red center from the total area to find the area of the blue border:
Aborder = Atotal - Acenter = 36π - 4π = 32π square feet.
To provide an answer rounded to the nearest tenth, we approximate π to 3.14:
Aborder ≈ 32 * 3.14 ≈ 100.48 square feet, which rounds to 100.5 square feet as the area of the blue border.

Further explanationSolving linear equation mean calculating the unknown variable from the equation.
Let the linear equation : y = mx + c
If we draw the above equation on Cartesian Coordinates , it will be a straight line with :
m → gradient of the line
( 0 , c ) → y - intercept
Gradient of the line could also be calculated from two arbitrary points on line ( x₁ , y₁ ) and ( x₂ , y₂ ) with the formula :
[tex]\large {m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
If point ( x₁ , y₁ ) is on the line with gradient m , the equation of the line will be :
[tex]y - y_1 = m ( x - x_1 )[/tex]
Let us tackle the problem.
Let :
The number that Dennis started with is X
If he adds 0.5 to that number and then multiplies the new result by 4 , then:
[tex]( X + 0.5 ) \times 4[/tex]
If he then subtracts 2 and divides the number by 2 , then:
[tex]\frac{[ ( X + 0.5 ) \times 4 ] - 2}{2}[/tex]
If his final answer is 48 , then :
[tex]\frac{[ ( X + 0.5 ) \times 4 ] - 2}{2} = 48[/tex]
[tex][ ( X + 0.5 ) \times 4 ] - 2 = 48 \times 2[/tex]
[tex]( X + 0.5 ) \times 4 = 48 \times 2 + 2[/tex]
[tex]( X + 0.5 ) \times 4 = 96 + 2[/tex]
[tex]( X + 0.5 ) \times 4 = 98[/tex]
[tex]( X + 0.5 ) = \frac{98}{4}[/tex]
[tex]( X + 0.5 ) = \frac{49}{2}[/tex]
[tex]X = \frac{49}{2} - \frac{1}{2}[/tex]

a right rectangular prism with a square base is cut parallel to its base the shaoe exposed is a cross section which shape bast describes this cross section?
A-triangle
B-trapezoid
C-square
D-rectangle not a square
A cross section obtained by cutting a right rectangular prism with a square base parallel to its base will also be a C. square, as it reflects the shape of the prism's base.
The question is asking about the shape of a cross section obtained by cutting a right rectangular prism with a square base parallel to its base. Such a cut would expose a shape on the surface of the prism that directly corresponds to the shape of the base. Since the base is given as a square, the cross section in this case would also be a square. The hypothesis of the right angle implies that the sides of the prism are perpendicular to the base, thereby maintaining the square shape upon slicing parallel to the base.
The cross section would not be a triangle (option A) or a trapezoid (option B), as these shapes do not correspond to a square base. It would not be a rectangle that is not a square (option D), because the length and width of the cross section would be the same, maintaining its square shape. Therefore, the correct answer is option C - a square.

Ernesto plans to build a pen for his pet iguana. Think about these two different questions. What is the area of the largest rectangular pen that he can make with 400 meters of fencing? What is the area of the largest circular pen he can make with the 400 meters of fencing?
Final answer:
Given 400 meters of fencing, constructing a square pen would result in an area of 10,000 square meters, while a circular pen would yield approximately 12,732 square meters, making the circular pen the larger option.
Explanation:
Ernesto wants to construct the largest possible pen for his iguana using 400 meters of fencing. To determine the maximum area of a rectangular pen, we can use the principle that a square will always provide the largest area for a given perimeter. In the case of a rectangular enclosure, we form a square with each side being one-fourth of the total available fencing, here being L/4 where L is 400 meters. Thus, each side of the square would be 400/4 = 100 meters. The area of such a square would be side × side = 100 m × 100 m = 10,000 square meters.
For the circular pen, the entire length of fencing would be the circumference of the circle. Given the formula for circumference is C = 2πr, where r is the radius, we set 400 = 2πr to solve for r, which is approximately 63.66 meters. The area of a circle is given by A = πr², which would then be approximately π(63.66)^2 ≈ 12,732 square meters. Therefore, a circular pen would provide a larger enclosed area compared to a square one given the same amount of fencing.

How many outcomes are there for the event of rolling a 6-sided number cube and then spinning a 4-part spinner?
Final answer:
To determine the total outcomes for a 6-sided die and a 4-part spinner, simply multiply the outcomes for each, resulting in 24 unique outcomes.
Explanation:
When calculating the number of outcomes for rolling a 6-sided die and then spinning a 4-part spinner, we need to consider the principle of counting. The die has six possible outcomes: 1, 2, 3, 4, 5, and 6. The spinner has four possible outcomes.
To find the total number of combined outcomes, we multiply the number of outcomes of the die by the number of outcomes of the spinner. Therefore, the total number of outcomes is 6 (from the die) times 4 (from the spinner) which equals 24 unique outcomes.

One cubic foot of sand weighs about 100 pounds. Approximate the weight of the cone-shaped pile of sand. Round your answer to the nearest hundred pounds.
To approximate the weight of a cone-shaped pile of sand, find the volume of the cone using the formula V = (1/3)πr²h. Multiply the volume by the weight of one cubic foot of sand (100 pounds) to find the weight of the pile. Round to the nearest hundred pounds.
Explanation:To approximate the weight of a cone-shaped pile of sand, we first need to find the volume of the cone.
The formula for the volume of a cone is V = (1/3)πr²h, where r is the radius of the base and h is the height.
Let's say the radius is 2 feet and the height is 5 feet.
Plugging these values into the formula, we get V = (1/3)π(2²)(5) = 20π.
Now, since one cubic foot of sand weighs about 100 pounds, we can multiply the volume of the cone by 100 to find the approximate weight.
Therefore, the weight of the cone-shaped pile of sand is approximately 20π × 100 = 2000π pounds.
Rounding to the nearest hundred pounds, the weight is approximately 6283 pounds.

Mathematically, an expression is a combination of numbers, variables, operations, and functions that are composed together according to specific rules to represent a computation or relationship of mathematics. It can be thought of as a mathematical phrase or formula.
Part A: Let's represent the number of desserts Heather will make with the variable "d".
The expression that represents the number of strawberries Heather needs for the desserts can be written as:
[tex]4 \times d[/tex].
Here, the variable "d" represents the number of desserts Heather will make.
Part B: If Heather has 24 ounces of strawberries, we can set up an equation to determine the number of desserts she can make.
[tex]4 \times d[/tex] = 24 ounces.
To solve for "d," we need to isolate it on one side of the equation. We can do this by dividing both sides of the equation by 4 ounces/dessert:
d (desserts) = [tex]\frac{24}{4 }[/tex]
Simplifying the right side of the equation:
d (desserts) = 6 desserts.
