The answer is s=√225 in. The area of a square is A = s², meaning that the area of the square is equal to the length of one side of the square squared.

A four-sided polygon with all sides equal in length. The interior angles of a square are right angles, and the opposite sides are parallel. The four sides of a square meet at its four vertices.

In this case, s is the side length.

To find the side length, we must take the square root of 225 in², which is equal to 15 in.

Therefore, the side length of the square is s=√225 in.

This is because taking the square root of a number is the same as finding the number whose square is equal to the given number.

In this case, the number whose square is equal to 225 in² is 15 in.

Hence, the side length of the square is s=√225 in.

Now, Mean < Median => Data is left - skewed. Similarly, mean(x₂ column ) = 20.83333 and median(x₂ column) = 21

Mean = 20.83

Median = 21

Mean ≈ Median => Data is symmetric. input : = mean(x₃) ; output : 41.3

input : = median(x₃) ; output: 39.5

Mean = 41.3

The negative sign indicates that the boat traveled in the opposite direction of its intended destination, and it traveled a distance of 2.55 miles.

The speed of the motorboat is given as -3.4 miles per hour, which means that the boat is moving in the opposite direction of its intended destination. If we assume that the boat is moving at a constant speed of -3.4 miles per hour for 0.75 hours, we can use the formula:

distance = speed x time

where distance is the distance traveled, speed is the speed of the boat, and time is the time for which the boat travels at that speed.

Plugging in the given values, we get:

distance = -3.4 miles/hour x 0.75 hour

distance = -2.55 miles

Answer:

Let x be the amount of Australian dollars the bank buys and sells.

The bank earns a profit by selling the Australian dollars at a higher rate than it bought them.

Profit = Selling rate - Buying rate

Profit per unit = Selling rate - Buying rate = Rs.132.85 - Rs.132 = Rs.0.85

To earn a profit of Rs. 7000, the bank must sell x Australian dollars at a profit of Rs.0.85 per unit, so:

Profit = x * 0.85

x = Profit / 0.85

x = 7000 / 0.85

x = 8235.29

Therefore, the bank should buy and sell 8235.29 Australian dollars to earn a profit of Rs.7000.

Let's first find the total volume of clay used for the cone and the sphere:

For the cone, we need the formula for the volume of a cone: Vcone = (1/3)πr^2h, where r is the radius of the base and h is the height.

Let's assume the cone has a radius of 5 millimeters and a height of 10 millimeters. Then, the volume of the cone is:

Vcone = (1/3)π(5^2)(10) = (1/3)π(250) = 83.33 cubic millimeters (rounded to two decimal places)

For the sphere, we need the formula for the volume of a sphere: Vsphere = (4/3)πr^3, where r is the radius.

Let's assume the sphere has a radius of 4 millimeters. Then, the volume of the sphere is:

Vsphere = (4/3)π(4^3) = (4/3)π(64) = 268.08 cubic millimeters (rounded to two decimal places)

The total volume of clay used for the cone and the sphere is:

Vcone + Vsphere = 83.33 + 268.08 = 351.41 cubic millimeters (rounded to two decimal places)

To find the amount of clay left for decorations, we can subtract this volume from the original amount of clay:

2000 - 351.41 = 1648.59 cubic millimeters (rounded to two decimal places)

Therefore, Walter has 1648.59 cubic millimeters of clay left for decorations.

Exponents are a mathematical notation used to represent repeated multiplication and are a fundamental tool in various fields. The values of [tex]16^2[/tex] and [tex]12^2[/tex] are [tex]16^2[/tex] = 16 x 16 = 256, [tex]12^2[/tex] = 12 x 12 = 144

To rewrite each exponent as a single number, we can evaluate them using multiplication. For example, [tex]16^2[/tex] can be rewritten as 16 x 16, which equals 256. Similarly, [tex]12^2[/tex] can be rewritten as 12 x 12, which equals 144.

The exponent is a small number written above the base, which indicates the number of times the base should be multiplied by itself.

For example, the exponent 3 written above the base 2 means that we should multiply 2 by itself three times: 2 x 2 x 2 = 8. So, [tex]2^3[/tex] is equal to 8.

So, the values of [tex]16^2[/tex] and [tex]12^2[/tex] are:

[tex]16^2[/tex] = 16 x 16 = 256

[tex]12^2[/tex] = 12 x 12 = 144

By evaluating the exponents as single numbers, we can simplify the expressions they appear in and make them easier to work with.

They are used to represent large and small numbers in a compact form, and they simplify calculations by allowing us to perform repeated multiplication more efficiently.

The length of the ramp (y) is C. 36.9 feet

We can use trigonometry to find out the answer. Here we have given the opposite side length and the angle of elevation. Hence we can use the trigonometric ratio of tangent.

Let's see the steps for solving the problem.

Let AB be the height of the airplane door from the ground, and BC be the ramp's length. Also, let angle BAC be the angle of elevation of the ramp from the ground.

So,angle BAC = 31°andAB = 19 feet.

To find the length of the ramp (BC), we can use the tangent ratio of the angle of elevation.

tan θ = perpendicular/base

Here, the perpendicular is AB and the base is BC.tan 31° = AB/BC

Now, substitute the given values in the equation.

tan 31° = 19/BC

1/√3 = 19/BC

√3 = 19/BC

BC = 19/√3 feet [dividing both sides by √3]

We need to simplify the above answer.

We can multiply and divide the numerator by √3.BC = 19/√3 * √3/√3BC = 19√3/3

Therefore, the length of the ramp is BC = 19√3/3 feet.

we must have made an incorrect assumption along the way. One possible mistake is to assume that the  exterior angle of ∠3 is formed by extending the side opposite to ∠3.

What is Triangle ?

In geometry, a triangle is a 2-dimensional polygon that is formed by connecting three non-collinear points with straight lines.

To find the measure of ∠3, we can use the fact that the sum of angles in a triangle is 180 degrees. Therefore, we can write:

∠3 + ∠4 + ∠5 = 180

However, we don't know the measures of ∠4 and ∠5, so we need to use additional information from the problem to find them.

Since ∠3 is in the same triangle as ∠4 and ∠5, we can use the fact that the exterior angle of a triangle is equal to the sum of its remote interior angles. In other words:

∠4 + ∠5 = exterior angle of ∠3

We don't know the measure of the exterior angle of ∠3 either, but we can use the fact that it is supplementary to ∠3. Therefore:

exterior angle of ∠3 + ∠3 = 180

Combining these equations, we can solve for ∠3:

exterior angle of ∠3 + ∠3 = 180

∠4 + ∠5 = exterior angle of ∠3

∠3 + ∠4 + ∠5 = 180

Substituting ∠4 + ∠5 for the exterior angle of ∠3 in the first equation, we get:

∠3 + (∠4 + ∠5) = 180

∠3 + (exterior angle of ∠3) = 180

Simplifying, we get:

∠3 + (∠4 + ∠5) = 180

2∠3 + (∠4 + ∠5) = 180

2∠3 + exterior angle of ∠3 = 180

Now, we need to know the value of the exterior angle of ∠3. It is formed by extending one of the sides of the triangle containing ∠3, ∠4, and ∠5, and it is equal to the sum of the other two angles in the triangle. We don't have enough information to determine which side is extended, so we will assume that it is the one opposite to ∠3. In this case, we have:

exterior angle of ∠3 = ∠4 + ∠5

Substituting in the equation above, we get:

2∠3 + ∠4 + ∠5 = 180

Now, we can solve for ∠3:

2∠3 + ∠4 + ∠5 = 180

2∠3 = 180 - (∠4 + ∠5)

2∠3 = 180 - (exterior angle of ∠3)

2∠3 = 180 - (∠4 + ∠5)

2∠3 = 180 - (∠3 + ∠4 + ∠5)

2∠3 = 180 - 180

2∠3 = 0

∠3 = 0

However, this result doesn't make sense, because an angle can't have a measure of 0 degrees in a triangle.

Therefore, we must have made an incorrect assumption along the way. One possible mistake is to assume that the exterior angle of ∠3 is formed by extending the side opposite to ∠3.

The maximum volume that a cylinder with a surface area of 90 can have is approximately 27.05 cubic units

To solve this problem, we need to use the formulas for the surface area and volume of a cylinder

Surface area = 2πr^2 + 2πrh

Volume = πr^2h

where r is the radius of the base of the cylinder, h is the height of the cylinder, and π is approximately equal to 3.14159.

We want to find the maximum volume that a cylinder with a surface area of 90 can have. Let's first solve the surface area formula for h

90 = 2πr^2 + 2πrh

45 = πr^2 + πrh

45/π = r^2 + rh/π

Next, we can solve the volume formula for h

V = πr^2h

h = V/(πr^2)

Now we substitute this expression for h into the surface area formula

45/π = r^2 + r(V/(πr^2))

45/π = r^2 + V/r

To find the maximum volume, we need to find the value of V that maximizes this expression. We can do this by taking the derivative with respect to r and setting it equal to zero

d/dx (r^2 + V/r) = 2r - V/r^2 = 0

2r = V/r^2

r^3 = V/2

Now we can substitute this expression for V into the surface area formula to find the corresponding value of r

45/π = r^2 + r(V/(πr^2))

45/π = r^2 + r/2r^2

45/π = r^2 + 1/(2r)

45/π - 1/(2r) = r^2

r^2 = (45/π - 1/(2r))

r^4 = 45r/(π) - 1/4

We can solve this quartic equation for r using numerical methods, such as the Newton-Raphson method. Alternatively, we can use trial and error to approximate the value of r that satisfies this equation

The dimensions of the garden that minimize the cost of materials are L = 15√15 feet and W = 5√15 feet.

To minimize the cost of materials for the given rectangular garden, we need to find the dimensions that minimize the total cost of the brick wall and the fence.

Let's assume the length of the garden is L and the width is W. Then, the area of the garden is given by LW = 75. The garden is to be surrounded on three sides by the brick wall, so the total length of the wall required is 2L + W.

The cost of the brick wall is $10 per foot, so the cost of the wall is 10(2L + W). The cost of the fence on the remaining side is $5 per foot, so the cost of the fence is 5W.

Hence, the total cost of materials C is given by:

C = 10(2L + W) + 5W

Simplifying this equation, we get:

C = 20L + 15W

Using the area formula LW = 75, we can solve for one of the variables in terms of the other. For example, we can solve for W as follows:

W = 75/L

Substituting this into the equation for C, we get:

C = 20L + 15(75/L)

To minimize C, we can take the derivative of C with respect to L, set it equal to zero, and solve for L:

dC/dL = 20 - 1125/L^2 = 0

Solving for L, we get:

L = 15√15

Substituting this value of L back into the equation for W, we get:

To identify an outlier in a set of numbers, we first need to determine the central tendency of the data, such as the mean or median. One common method for identifying outliers is to use the interquartile range (IQR).

To do this, we first need to find the median of the data set:

45, 52, 17, 63, 57, 42, 54, 58

Arranging them in ascending order:

17, 42, 45, 52, 54, 57, 58, 63

The median is the middle value, which is 54.

Next, we need to find the IQR. The IQR is the range between the first and third quartiles of the data. The first quartile (Q1) is the median of the lower half of the data, and the third quartile (Q3) is the median of the upper half of the data.

To find Q1 and Q3, we split the data into two halves:

Lower half: 17, 42, 45, 52

Upper half: 54, 57, 58, 63

Q1 is the median of the lower half, which is (42 + 45)/2 = 43.5.

Q3 is the median of the upper half, which is (57 + 58)/2 = 57.5.

Therefore, the IQR is 57.5 - 43.5 = 14.

Finally, we can identify outliers as any data point that falls outside the range of 1.5 times the IQR above Q3 or below Q1.

The upper limit is Q3 + 1.5(IQR) = 57.5 + 1.5(14) = 78.5.

The lower limit is Q1 - 1.5(IQR) = 43.5 - 1.5(14) = 22.5.

The only number in the given set that falls outside this range is 17, which is less than the lower limit. Therefore, 17 is the outlier in this data set.

Answer:

17

Step-by-step explanation:

In the set of numbers: 45, 52, 17, 63, 57, 42, 54, 58, the outlier is the number 17.

An outlier is a data point that is significantly different from other data points in the set. In this case, 17 is much smaller than the other numbers in the set and is considered an outlier.

Answer:

To find the area of a shape, you need to know the formula for the specific shape you are dealing with. Here are some common shapes and their corresponding area formulas:

Once you have identified the shape and the formula for its area, plug in the appropriate values and calculate the area. Make sure to label your answer with the correct units (e.g. square inches, square feet, etc.).
