Answer:
The median is 11.
Step-by-step explanation:
To find the median, you need to put all of the numbers in order.
In this case it would go:
2, 5, 8, 10, 10, 12, 14, 17, 20, 22
Now you find the middle number. Since there is an even amount of numbers, the median will fall between two different numbers. These numbers are 10 and 12. The median will be the number in between these two, which is 11. Therefore, the median is 11.

order the measurements from greatest to least 45 inches, 6 yards, and 2 and1/4 feet
Answer:
2.25 feet, 45 inches, and 6 yards
Step-by-step explanation:
first, convert all to the same unit of measurement
I will use inches
45 inches = 45 inches
6 yards, 1 yard = 3 feet so 6 yards are equal to 18 feet and 1 foot is equal to 12 inches so 12*18 is 216 inches so 6 yards = 216 inches
Next 1 foot equals 12 inches so 2.25 * 12 = 27 so 2.25 feet = 27 inches.
Now let's look at the complete conversion
45 inches
6 yards = 216 inches
2.25 feet = 27 inches
looking at the inches we can see that 27 is the least then 45 then 216 therefore
2.25 feet < 45 inches < 6 yards so the order is
2.25 feet, 45 inches, and 6 yards
What is ¨the amount of space in a gift box for earrings¨ unit of measurement
A - Square meters
B - Yards
C - Cubic inches
D - Cubic feet
E - Square centimeters
The amount of space in a gift box for earrings would typically be measured in cubic inches (C).
how to solve the question?
Cubic inches is a unit of volume that is commonly used to measure the capacity of small, enclosed spaces like boxes, containers, and packaging. It is defined as the volume of a cube that measures one inch on each side.
For a gift box designed to hold earrings, the volume of the box would need to be sufficient to accommodate the size of the earrings and any additional padding or decorative elements. Since earrings are small, the gift box would likely have a small volume, measured in cubic inches.
Other units of measurement, like square meters or yards, are used to measure the area of two-dimensional surfaces like floors, walls, or yards. Square centimeters are also a unit of area measurement, but they are much smaller than square meters or yards, and may be used to measure the surface area of small objects.
Cubic feet is a larger unit of volume measurement that may be used for larger boxes or containers, like shipping crates or storage bins. However, for a gift box designed specifically for earrings, cubic inches is likely the most appropriate unit of measurement.

WZ and XR are diameters find the measure of XZ in circle C
The length of XZ in circle C is equal to the √34. This can be found using the Pythagorean theorem and the fact that XZ is a radius of the circle.
As WZ and XR are diameters, they intersect at the center of the circle, which we'll call point O.
Since WX is a chord of the circle, we can use the perpendicular bisector of WX, which passes through O, to find the length of XZ.
Let's call the midpoint of WX point M. Then OM is perpendicular to WX and bisects it.
So we have two right triangles, OXM and MXZ. We know that OM = 5 and XM = 3 (half of WX).
Using the Pythagorean theorem, we can find the length of OX:
OX² = OM² + MX²
OX² = 5² + 3²
OX² = 34
OX = √(34)
Since XZ is also a radius of the circle, we have XZ = OX = √(34).
Therefore, the measure of XZ in circle C is √(34).

a newsletter publisher believes that more than 51% of their readers own a personal computer. is there sufficient evidence at the 0.05 level to substantiate the publisher's claim? state the null and alternative hypotheses for the above scenario.
Answer: The null hypothesis for this scenario is that the proportion of readers who own a personal computer is 0.51 or less:
H0: p <= 0.51
The alternative hypothesis is that the proportion of readers who own a personal computer is greater than 0.51:
Ha: p > 0.51
To test this hypothesis, we would need to collect a random sample of readers and determine the proportion of readers who own a personal computer in the sample. We could then use a one-sample proportion test to determine whether the proportion in the sample is significantly different from the null hypothesis value of 0.51. If the p-value is less than 0.05, we would reject the null hypothesis and conclude that there is sufficient evidence to substantiate the publisher's claim that more than 51% of their readers own a personal computer. If the p-value is greater than or equal to 0.05, we would fail to reject the null hypothesis and conclude that there is not sufficient evidence to substantiate the publisher's claim.

(1 point) a 17 foot ladder is leaning against a wall. if the top slips down the wall at a rate of 2 ft/s, how fast will the foot be moving away from the wall when the top is 16 feet above the ground?
When the top of the ladder is 16 feet above the ground, the foot of the ladder is moving away from the wall at a speed of approximately 3.86 feet per second.
This is a related rates problem involving a ladder leaning against a wall. Let's denote the distance of the foot of the ladder from the wall as x, and the height that the top of the ladder reaches as y. We are given that dy/dt = -2 ft/s (since the top is slipping down the wall) and we want to find dx/dt (the speed at which the foot of the ladder is moving away from the wall) when y = 16 ft.
Using the Pythagorean theorem, we have:
[tex]x^2 + y^2 = 17^2[/tex]
Differentiating implicitly with respect to time, we get:
[tex]2x(dx/dt) + 2y(dy/dt) = 0[/tex]
Substituting the given values, we get:
[tex]2x(dx/dt) + 2(16)(-2) = 0[/tex]
Simplifying, we get:
[tex]2x(dx/dt) = 64[/tex]
Dividing both sides by 2x, we get:
dx/dt = 64/(2x)
We know that y = 16, so we can use the Pythagorean theorem to solve for x:
[tex]x^2 + 16^2 = 17^2x^2 = 17^2 - 16^2x^2 = 33[/tex]
Taking the square root, we get:
[tex]x = sqrt(33)[/tex]
Substituting this into our expression for dx/dt, we get:
[tex]dx/dt = 64/(2*sqrt(33)) ≈ 3.86 ft/s[/tex]
Therefore, when the top of the ladder is 16 feet above the ground, the foot of the ladder is moving away from the wall at a speed of approximately 3.86 feet per second.

(C.) reflection and (D.) rotation produce congruent images.
What three transformations are congruent?
We can generate congruent shapes by combining the three types of transformations: rotations, reflections, and translations. Actually, using a combination of one or more of these three transformations, any pairs of congruent shapes can be matched to one another.
(A) Dilation, (B) horizontal stretch, and (E) translation do not produce congruent images because they change the size, shape, and/or orientation of the original object.
(C) Reflection produces congruent images because the resulting image is a mirror image of the original object, and therefore has the same size and shape.
(D) Rotation produces congruent images because the resulting image is the same shape and size as the original object, just rotated to a different orientation.

Answer:
Step-by-step explanation:
To find P * 1, we need to find all pairs of elements in P that have a difference of 1. Let's start by listing the elements of P:
P = {(1, 2), (2, 5), (3, 8), (4, 11)}
Now, we can find all pairs of elements in P that have a difference of 1:
(1, 2), (2, 5) -> (1, 5)
(2, 5), (3, 8) -> (1, 3)
(3, 8), (4, 11) -> (1, 3)
Therefore, P * 1 = {(1, 5), (1, 3), (1, 3)} = {(1, 5), (1, 3)} (since the last pair is a duplicate).
(b) The given relation is: y = 4x
The elements of this relation are all pairs (x, y) such that y = 4x. For example, (1, 4), (2, 8), (3, 12), etc.

function w(x) = x +4.
Which function defines the area of the rectangle?
Hint: A = 1- w
O a(z)=2x² + 9x +4
O a(z)=2x² + 5x +4
O a(z)=2-3
O a(z) = 3r+5
The correct function that defines the area of the rectangle is:
A(z) = 2[tex]x^{2}[/tex]+ 9x + 4 (option A).
HOW TO CALCULATE AREA OF THE RECTANGLE?The area of a rectangle is given by the product of its length and width. So, the function that defines the area of the rectangle would be:
A(x) = l(x) * w(x)
where l(x) is the length of the rectangle given by the function 1(x) = 2x + 1, and w(x) is the width of the rectangle given by the function w(x) = x + 4.
Substituting the given functions for length and width, we get:
A(x) = (2x + 1) * (x + 4)
Now, we can expand and simplify the expression:
A(x) = [tex]2x^2 + 8x + x + 4[/tex]
A(x) = [tex]2x^2 + 9x + 4[/tex]
