The difference in the medians is ___ times the IQR

By using Euclid's first book, we can prove that the quadrilateral produced by perpendicular, unequal, bisecting diagonals is a kite. A kite is a quadrilateral with two pairs of adjacent sides that are equal in length. In this case, the two pairs of adjacent sides are formed by the diagonals bisecting the quadrilateral into four smaller triangles with equal areas.

According to Euclid's first book, when two lines intersect at a right angle (perpendicular), they form four right angles. In the case of a quadrilateral with perpendicular, unequal, bisecting diagonals, the diagonals intersect at a right angle and divide the quadrilateral into four smaller triangles with equal areas.

1. Draw a quadrilateral with perpendicular, unequal, bisecting diagonals.
2. Label the points where the diagonals intersect as A, B, C, and D.
3. Label the point where the diagonals intersect as E.
4. Use Euclid's first book to prove that the angles at E are all right angles.
5. Use Euclid's first book to prove that the four triangles formed by the diagonals are congruent (equal in area).
6. Use the definition of a kite to prove that the quadrilateral is a kite (two pairs of adjacent sides are equal in length).
7. Therefore, the quadrilateral produced by perpendicular, unequal, bisecting diagonals is a kite.

The trigonometric value of angle Cos Z would be = 77°

A trigonometric value is defined as those values that are based on three major trigonometric ratios such as the Sine, Cosine, and Tangent.

According to the rules of trigonometry the following is carried out:

Sine or sin θ = Side opposite to θ / Hypotenuse = XY / XZ

Cosines or cos θ = Adjacent side to θ / Hypotenuse = YZ / XY

Tangent or tan θ =Side opposite to θ / Adjacent side to θ = XY / YZ.

Therefore, the trigonometric value of cos Z = adj/hypo = 9/40 = 0.225

Z = Cos^-1 0.225.

The answers for each line are:

a) the slope is  -2

b) The slope is 2/5 and the y-intercept is -2.

c) x = 10/4

d) y = -7x - 2

A linear equation can be written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

We know that if the line passes through (x₁, y₁) and (x₂, y₂), then the slope is:

a = (y₂ - y₁)/(x₂ - x₁)

a) Then the slope of the line that passes through (2, -5) and (-2, 3) is:

a = (3 + 5)/(-2 - 2) = 8/-4 = -2

b) The line is 2x - 5y = 10

Isolating y we will get:

5y = 2x - 10

y = (2/5)*x - 2

The slope is 2/5 and the y-intercept is -2.

c) Here we need to solve:

-4 = (1 + 9)/(0 - x)

-4*-x = 10

x = 10/4

d) if the slope is -7, then we have:

y = -7x + b

And the line also passes through (-1, 5), then:

5 = -7*-1 + b

5 = 7 + b

5 - 7  =b

-2 = b

The line is:

The combined rate of all three workers is 6 fences per 3 hours.

To find out how long it would take for all three painters to paint the fence together, we need to find the combined rate of work for Abel, Baker, and Chuck.

Let's first find the rate of work for each painter individually.

Abel's rate of work is 1/18 of the fence per hour (since he can paint the whole fence in 18 hours).

Baker's rate of work is twice as fast as Abel's, so his rate of work is 2/18 (or 1/9) of the fence per hour.

Chuck's rate of work is three times as fast as Abel's, so his rate of work is 3/18 (or 1/6) of the fence per hour.

Now, to find the combined rate of work for all three painters, we simply add their individual rates of work together:

1/18 + 1/9 + 1/6 = 1/18 + 2/18 + 3/18 = 6/18 = 1/3

This means that together, the three painters can paint 1/3 of the fence per hour.

To find out how long it would take them to paint the whole fence, we simply divide the total amount of work (1 whole fence) by their combined rate of work (1/3 of the fence per hour):

1 ÷ 1/3 = 3

So it would take the three painters 3 hours to paint the whole fence together.

Step-by-step explanation:

You want the range of the graph shown.

The range is the vertical extent of the graph. This graph has a minimum at y=-4 and a maximum of y=2. All values between these are represented, so the range is ...

  [-4, 2] . . . . or -4 ≤ y ≤ 2

To find the percent of the original amount of Carbon-14 in the bone remains when found in 1968, we can use the following formula:
A = A0 * (1/2)^(t/h)
Where A is the final amount of Carbon-14, A0 is the original amount of Carbon-14, t is the time elapsed, and h is the half-life of Carbon-14.

Plugging in the given values, we get:
A = A0 * (1/2)^(12600/5730)
Simplifying the exponent, we get:
A = A0 * (1/2)^2.199
Using a calculator, we find that (1/2)^2.199 is approximately 0.153, so:
A = A0 * 0.153
This means that the final amount of Carbon-14 is 15.3% of the original amount of Carbon-14. Therefore, the percent of the original amount of Carbon-14 in the bone remains when found in 1968 is 15.3%.

Answer:

The correct next step is the answer choice

x^2+b/a x=-c/a

Step-by-step explanation:

The given information tells us that the sin a is equal to 5/13, and that 0 is less than a, which is less than π/2. Therefore, the exact function value for sin a is 5/13 and the value for a is approximately  5/12.

We are given that sin(a) = 5/13 and 0 < a < π/2. We can use the Pythagorean identity cos²(a) + sin²(a) = 1 to find cos(a):

cos²(a) + sin²(a) = 1

cos²(a) + (5/13)² = 1

cos²(a) = 1 - (5/13)²

cos²(a) = 144/169

cos(a) = ± 12/13

Since 0 < a < π/2, we know that cos(a) > 0. Therefore, cos(a) = 12/13. We can use the definition of tangent to find tan(a):

tan(a) = sin(a)/cos(a) = (5/13)/(12/13) = 5/12

Therefore, the exact function value we were asked to find is tan(a) = 5/12.

The sum of the perimeters of the three squares displayed on the computer monitor is 36√7 cm.

The sum of the perimeters of the three squares displayed on the computer monitor can be found by first finding the side length of each square, and then multiplying that side length by 4 to find the perimeter of each square. Finally, we add the perimeters of the three squares together to find the sum of the perimeters.

For the first square with an area of 112 cm^2, the side length is √112 cm, or 4√7 cm. The perimeter of this square is 4(4√7 cm) = 16√7 cm.

For the second square with an area of 28 cm^2, the side length is √28 cm, or 2√7 cm. The perimeter of this square is 4(2√7 cm) = 8√7 cm.

For the third square with an area of 63 cm^2, the side length is √63 cm, or 3√7 cm. The perimeter of this square is 4(3√7 cm) = 12√7 cm.

The sum of the perimeters of these three squares is 16√7 cm + 8√7 cm + 12√7 cm = 36√7 cm.

Answer:

Let's first calculate the number of compounding periods in a year, given that the interest is compounded quarterly:

Number of compounding periods in a year = 4 (since there are 4 quarters in a year)

Next, let's use the formula for compound interest to find the annual interest rate:

A = P (1 + r/n)^(nt)

Where:

A is the balance after t years

P is the principal (initial balance)

r is the annual interest rate (what we are looking for)

n is the number of compounding periods in a year

t is the time in years

We know that P = $1250, A = $1406.08, n = 4, and t = 9/12 years (since the interest is earned for 9 months).

Plugging these values into the formula, we get:

$1406.08 = $1250 (1 + r/4)^(4/3)

Dividing both sides by $1250 and taking the cube root of both sides, we get:

1 + r/4 = (1406.08/1250)^(3/4)

1 + r/4 = 1.038

Subtracting 1 from both sides, we get:

r/4 = 0.038

Multiplying both sides by 4, we get:

r = 0.152

Therefore, the annual interest rate is 15.2%.

We can expect 2 black horses out of a sample of 15 horses from the stable.

To determine how likely something is gonna occur, use probability. The event is typically stated as a number between 0 and 1, with 0 denoting impossibility and 1 denoting certainty.

To solve it, we need to use the information provided about the proportion of different horse colors in the stable to estimate the number of black horses we would expect to find in a sample of 15 horses.

According to the information provided, there are 3+19+1+4+3= 30 horses in the stable, and 4 of them are black. Therefore, the proportion of black horses in the stable is:

4/30 = 0.1333...

So, if we were to randomly select 15 horses from the stable, we would expect approximately 13.33% of them to be black. To find the expected number of black horses in a sample of 15 horses, we can multiply the proportion by the sample size:

0.1333... x 15 = 1.999...
