a pair of headphones originally costs 95$ and is on sale for 70$ what is the percent change in the price of the headphones? be sure to show whether it is a percent increase or decrease.
The percent decrease in the price of the headphones is 26.32%.
Explanation:
To find the percent change in price, we can use the following formula:
percent change = (new value - old value) / old value * 100%
In this case, the old value is the original price of the headphones, which is $95.
The new value is the sale price, which is $70. Plugging these values into the formula, we get:percent change = (70 - 95) / 95 * 100%
percent change = -25 / 95 * 100%
percent change = -0.2632 * 100%
percent change = -26.32%
The negative sign indicates that the price has decreased, and the magnitude of the percent change is 26.32%, which means that the sale price is 26.32% lower than the original price.

determine whether the property is true for all integers, true for no integers, or true for some integers and false for other integers. justify your answers. the average of any two odd integers is odd.
The property of the average of any two odd integers being odd is true for all integers.
This is because the sum of any two odd integers is always an even integer. For example, if we take any two odd integers, say 3 and 7, then the sum of these two is 10, an even integer. Therefore, the average of 3 and 7, which is (3 + 7)/2, is also an even integer, in this case, 5.
Since all even integers are divisible by 2, the average of any two odd integers must be an odd integer.
Therefore, the property is true for all integers.

Answer:?
In response to stated question, we may state that You will need to stitch about 5.0089 metres of piping around the outside border of the area tablecloth, rounded to the closest 0.1 m, for a total length of 5.0 m.
What is area?The size of just an area on either a surface can be represented as an area. The area of an open surface or the border of a two half object is called to as the surface area, meanwhile the area of a horizontal region or planar region pertains to the area of a shape or planar layer. The entire amount of space occupied by a horizontal (2-D) surface or form of an item is referred as its area. With a pencil, draw an square on a sheet of paper. A two-dimensional character. The area of a form on paper is the quantity of area it takes up. Consider the square to be made up of smaller unit squares.
Begin by calculating the radius of the circular tablecloth. We know that the formula A = r2 gives the area of a circle, where A is the area and r is the radius. Hence we may rearrange this formula to find r:
r = √(A/π) = √(2/π) ≈ 0.7979 m (rounded to four decimal places) (rounded to four decimal places)
Now we must determine the circumference of the circle, which is the distance around the tablecloth's outside border. The circumference is calculated using the formula C = 2r.
C = 2π(0.7979) ≈ 5.0089 m
You will need to stitch about 5.0089 metres of piping around the outside border of the tablecloth, rounded to the closest 0.1 m, for a total length of 5.0 m.

the volume of the right cone below is 392\piπ units^3 3 . Find the value of xx.
The value of x is approximately 8.15.
To find the value of x, we need to use the formula for the volume of a cone, which is V = (1/3)πr^2h, where r is the
radius of the base and h is the height of the cone. We know that the volume of the cone below is 392π, so we can set
up the equation:
[tex]392π = (1/3)πx^2h[/tex]
Simplifying, we can divide both sides by π and multiply by 3 to get:
[tex]1176 = x^2h[/tex]
Using the Pythagorean theorem, we can relate the height, radius, and slant height of the cone:
[tex]h^2 + r^2 = x^2[/tex]
Since the cone is a right cone, we know that the radius is half of the diameter, which is equal to x/2. Substituting this in,
we get:
[tex]h^2 + (x/2)^2 = x^2[/tex]
Simplifying:
[tex]h^2 = x^2 - (x/2)^2
h^2 = 3x^2/4[/tex]
Now we can substitute this expression for [tex]h^2[/tex] into our equation for the volume:
[tex]1176 = x^2(3x^2/4)[/tex]
Simplifying again:
[tex]1176 = 3x^4/4[/tex]
[tex]1568 = 3x^4[/tex]
[tex]x^4 = 1568/3[/tex]
Taking the fourth root of both sides:
[tex]x = (1568/3)^(1/4)[/tex]
x ≈ 8.15

Step-by-step explanation:
in a large population, 64% of the people have been vaccinated. if 3 people are randomly selected, what is the probability that at least one of them has been vaccinated?
The probability that at least one of three randomly selected people has been vaccinated in a large population where 64% of people have been vaccinated is 0.784.
The probability that at least one of three randomly selected people has been vaccinated in a large population where 64% of people have been vaccinated can be calculated using the binomial probability formula.
The binomial probability formula is used to calculate the probability of a given number of successes from a given number of trials when the probability of success is constant. In this case, the number of trials is 3 (i.e. the three randomly selected people) and the probability of success is 64% (i.e. the probability that each of the randomly selected people has been vaccinated).
To calculate the probability that at least one of the three randomly selected people has been vaccinated, we first calculate the probability of none of them having been vaccinated:
P(none) = (1 - 0.64)^3 = 0.216
Then, the probability of at least one of them having been vaccinated is 1 - P(none) = 1 - 0.216 = 0.784.
In conclusion, the probability that at least one of three randomly selected people has been vaccinated in a large population where 64% of people have been vaccinated is 0.784.

If a client who weighs 207 lb (94.1 kg) is to receive 1.5 mg/kg of gentamicin sulfate iv three times each day, the nurse should administer 141 mg of gentamicin sulfate for each dose.
To calculate the dose of gentamicin sulfate that the nurse should administer to the client, we need to know the client's weight and the desired dosage, which in this case is 1.5 mg/kg.
First, we need to convert the client's weight from pounds to kilograms. To do this, we divide the client's weight in pounds by 2.205 to get the weight in kilograms:
207 lb ÷ 2.205 = 94.1 kg
Now that we have the client's weight in kilograms, we can calculate the dose of gentamicin sulfate for each administration:
1.5 mg/kg × 94.1 kg = 141.15 mg
We round 141.15 mg to the nearest whole number, which is 141 mg.

Write the equation of the trend line. Use the points (4, 12) and (12, 8).
The equation of the trend line is y = (-1/2)x + 14.
What is trend line?The overall pattern or trend in a collection of data is represented by a trend line, sometimes referred to as a regression line. In statistics, it is frequently used to illustrate the connection between two variables, one of which is the independent variable and the other the dependant variable. Regression analysis, which determines the line that most accurately fits the data points based on their connection, is used to compute the trend line. In order to anticipate or estimate future values of the dependant variable based on the independent variable, the equation of the trend line may then be utilised.
The slope of the line can be found using the formula:
slope = (change in y) / (change in x)
slope = (8 - 12) / (12 - 4)
slope = -4 / 8
slope = -1/2
Using the point slope form:
y - y1 = m(x - x1)
y - 12 = (-1/2)(x - 4)
y = (-1/2)x + 14
Hence, the equation of the trend line is y = (-1/2)x + 14.

Answer:
If x = 3 and y = 2.3^3, then we can evaluate y using exponents:
y = 2.3^3 = 2.3 × 2.3 × 2.3 = 12.167
So, y = 12.167 when x = 3.
Next, if we want to solve the equation y = 2[?] using order of operations, we need to evaluate what is inside the brackets first. We know that y = 12.167, so we can substitute that value into the equation:
y = 2[?]
12.167 = 2[?]
To solve for the missing value inside the brackets, we need to divide both sides by 2:
12.167 ÷ 2 = ?
6.0835 = ?
Therefore, the solution is y = 2(6.0835), or y = 12.167, which we already found earlier.
Draw a figure composed of three different rectangle that has a perimeter of 140 yards use measurements in yards in feet to label this side of your figures.
To create a figure of three rectangles with a perimeter of 140 yards, you can stack them on top of each other to make a plus sign, and label each side as 11 and 2/3 yards or 11 yards (by subtracting the fractions).
What is rectangle?A rectangle is a four-sided geometric shape that has four right angles (90 degree angles) and opposite sides that are parallel and of equal length. The length of a rectangle is its longer side, while the width is its shorter side.
According to given information:If we draw three rectangles stacked on top of each other like a plus sign, we can divide the perimeter of 140 yards by the number of sides, which is 12. This gives us a length of 11 and 2/3 yards per side.
To use only integers, we can subtract the fractions from each side to another, which gives us a length of 11 yards per side. We can then label each side of the figure with a length of 11 yards.
In the figure, we have three rectangles of equal size, with a length of 11 yards and a width of 35 yards. We can convert the measurements to feet by multiplying by 3, which gives us a length of 33 feet and a width of 105 feet.
Alternatively, if we wanted to use only whole numbers, we could increase the size of each rectangle slightly, so that the total perimeter is a multiple of 12. For example, we could make each rectangle 11.6667 yards by 35 yards, which gives us a total perimeter of 140.0008 yards. We can then divide this by 12 to get a length of 11 and 2/3 yards per side, and label each side with a length of 11 yards.

If 250 is divided in the ratio 3:7, then 75 is the smaller part. To find the smaller part of 250 divided in the ratio 3:7, you need to first find the total number of parts that the ratio represents.
The total number of parts in the ratio of 3:7 is 3+7=10.
Next, you need to find the value of one part.
To do this, divide the total amount by the total number of parts:
250 ÷ 10 = 25
This means that one part of the ratio is equal to 25.
To find the smaller part, you need to multiply the value of one part (25) by the ratio of 3/10 (which represents the smaller part of the total).

An angle in standard position on a unit circle measures 2pi/5 radians. what are the exact coordinates of where the terminal side intersects the unit circle?
Thank you!
Answer:
(x, y) = (cos(2π/5), sin(2π/5)) = ((1/4)(-1 + √5), (1/4)(2√5 + 2))
Step-by-step explanation:
In standard position, the initial side of an angle lies on the positive x-axis, and the terminal side rotates counterclockwise from the initial side.
Since the angle measures 2π/5 radians, we need to find the point on the unit circle that is π/5 radians past the positive x-axis.
Let (x, y) be the coordinates of the point on the unit circle where the terminal side intersects. We can use the following trigonometric identities to find the values of x and y:
cos(2π/5) = x
sin(2π/5) = y
These values can be determined using either a calculator or the unit circle. Alternatively, we can use the fact that the angle 2π/5 is a special angle and can be expressed exactly in terms of square roots:
cos(2π/5) = (1/4)(-1 + √5)
sin(2π/5) = (1/4)(2√5 + 2)
Therefore, the exact coordinates of the point where the terminal side intersects the unit circle are
(x, y) = (cos(2π/5), sin(2π/5)) = ((1/4)(-1 + √5), (1/4)(2√5 + 2))

solve the following polynomial inequality: x^2-5x-36>0
include all steps and place the answer in interval notation form.
please explain the steps and how you got the answer
Answer:
To solve the inequality x^2-5x-36>0, we need to find the values of x for which the expression is greater than zero.
One way to do this is by factoring the quadratic expression:
x^2-5x-36 = (x-9)(x+4)
The expression is positive when either both factors are positive or both factors are negative.
When both factors are positive: x-9 > 0 and x+4 > 0
Solving for x, we get x > 9 and x > -4. Therefore, x > 9.
When both factors are negative: x-9 < 0 and x+4 < 0
Solving for x, we get x < 9 and x < -4. Therefore, x < -4.
Now, we have two intervals: x < -4 and x > 9. To check whether the expression is positive within these intervals, we can pick a value within each interval and plug it into the expression.
Let's choose x = -5 (within x < -4) and x = 10 (within x > 9).
For x = -5:
x^2-5x-36 = (-5)^2-5(-5)-36
= 25+25-36
= 14
Since 14 is greater than zero, the expression is positive when x = -5.
For x = 10:
x^2-5x-36 = 10^2-5(10)-36
= 100-50-36
= 14
Since 14 is greater than zero, the expression is also positive when x = 10.
Therefore, the solution to the inequality x^2-5x-36>0 is x < -4 or x > 9, which can be written in interval notation as (-∞,-4) ∪ (9,∞).
Which results only in a horizontal compression of Y by a factor of 6?
Answer:
Y = 6*y
Step-by-step explanation:
We have Y = b * y by a factor of 6.
That is, b = 6.
now, to find what results only in a horizontal compression of y = b * y by a factor of 6.
By transformation rule, the function would be a horizontal compression f (a * x) if a> 1.
Therefore, knowing the above, the answer would be:
Y = 6 * y
