Step-by-step explanation:

The plane's distance is the hypotenuse of a right triangle with legs of

(50 -20)mi = 30 miles     and     30500 - 18000 = 12500 ft

                             for consistent units  12500ft/5280ft/mile = 2.36742 miles

Now just use Pythagorean theorem

Hypotenuse^2 = leg1^2 + leg2^2

               h^2    = 30^2 + 2.36742^2

                   h = ~ miles 30.093 miles  ( note that the vertical descent distance does not matter much)

    (this is 158 892 feet)

A house that has 2,100 sq ft of living area is more unusual than a house that sells for ​$125,000. This is because the probability of finding a house with 2,100 sq ft of living area is only 38.21% which is less than 5.86% which is the probability of finding a house that sells for ​$125,000.

A real estate agent has surveyed houses in twenty nearby zip codes in an attempt to put together a comparison for a new property that she would like to put on the market. The 1057 houses she surveyed have a mean price of ​$172,000, with a standard deviation of $30,000. The mean living area is 1567 sq​ ft, with a standard deviation of 210 sq ft. We are to find out which is more unusual, a house in that market that sells for ​$125,000 or a house that has 2,100 sq ft of living​ area? Let's answer this question step by step. We have,Mean of Price

= $172,000

Standard Deviation of Price

= $30,000

Mean of Living area

= 1567 sq ft

Standard Deviation of Living area

= 210 sq ft

The price of the house that is being sold is $125,000.The calculation to find the Z-score for the house that is selling at $125,000 is given by:

Z = (X- μ)/ σ

Where, X = Price of the house

= $125,000μ

= Mean Price

= $172,000σ

= Standard Deviation

= $30,000

Substitute the values and find the Z-score,

Z = (125,000-172,000) / 30,000 = -1.5667

We then look at the Z-table to find the probability of getting the Z-score value -1.5667. From the Z-table, we get the value of 0.0586 or 5.86%. The probability of finding a house that sells at $125,000 is 5.86% in that area.Now let's calculate the Z-score for a house that has 2,100 sq ft of living area using the formula,

Z = (X- μ)/ σ

Where, X = Living area

= 2100 sq ftμ

= Mean Living Area

= 1567 sq ftσ

= Standard Deviation

= 210 sq ft

Substitute the values and find the Z-score,

Z = (2100-1567) / 210

= 0.3

We then look at the Z-table to find the probability of getting the Z-score value 0.3. From the Z-table, we get the value of 0.3821 or 38.21%. The probability of finding a house with 2,100 sq ft of living area is 38.21% in that area.Therefore, a house that has 2,100 sq ft of living area is more unusual than a house that sells for ​$125,000. This is because the probability of finding a house with 2,100 sq ft of living area is only 38.21% which is less than 5.86% which is the probability of finding a house that sells for ​$125,000. Hence, a house with 2,100 sq ft of living area is more unusual in that area.

Answer:

Step-by-step explanation:

Given sinx< cos x and 0°< x < 90°, to get the possible value of x, we need to solve the given inequality for x.

sinx< cos x

Dividing both sides by cos x

sin x/cos x < cos x/cos x

tan x < 1

x < \(tan^{-1}1\)

x < 45°

Since x is less than 45°, then one of the possible value of x can be 30° since 30° is less than 45° and 30° falls within the given range of values.

In triangle xyz the line of reflection that produces the X²(2, 4) is equal to x-axis.

In the triangle ,

Vertices are X(-2, 4), Y(-9, 3), Z(-10, 7).

X²(2, 4) is reflected over the line of reflection to the point X'(a, b).

Such that the line joining X and X' is perpendicular to the line of reflection.

To determine the line of reflection that produces X²(2, 4).

Calculate the perpendicular bisector of the line segment between X and its image, X'.

First, find the coordinates of the image of X²(2, 4) under the line of reflection.

Reflecting over the y-axis would negate the x-coordinate of any point, while leaving the y-coordinate unchanged.

Thus, the image of X²(2, 4) under reflection over the y-axis is X'(-2, 4).

Next, find the midpoint of the line segment between X²(2, 4) and X'(-2, 4).

The midpoint formula is,

((x1 + x2)/2, (y1 + y2)/2)

Plugging in the coordinates of X²(2, 4) and X'(-2, 4), we get,

=((-2 + 2)/2, (4 + 4)/2)

=(0, 4)

Coordinates of the midpoint of the line segment between X²(2, 4) and its image, X'(-2, 4).

Line of reflection find the equation of the line passing through this midpoint and perpendicular to the y-axis.

Since the line is perpendicular to the y-axis, its slope is undefined.

And it is a vertical line passing through (0, 4), which is the equation of the x-axis.

Therefore, the line of reflection for the given condition is the x-axis.

the perimeter for the triangle, in the simplest form, is:

P = 8x + 1

For any two-dimensional figure, we define the perimeter as the sum of the lengths of its sides.

Here we have a triangle (3 sides) and the lengths are:

2x

2x + 3

4x - 2

So the perimeter is given by:

P = 2x + 2x + 3 + 4x - 2

Now we want to reduce this to the simplest form, so we can rewrite:

P = 2x + 2x + 4x + 3 - 2 = (2 + 2 + 4)*x + (3 - 2) = 8x + 1

We conclude that the perimeter for the triangle is:

The probability that more than 210 people will pass in front of his store is 0.2272.

In the question, we are given that a coffee shop owner wants to examine the number of customers who pass in front of his store in the morning from 7:00 A.M to 7:30 A.M.

We are asked to find the probability that more than 210 people will pass in front of his store if the mean number of customers during this time is 210.

This experiment follows a Poisson Distribution with a mean (λ) = 200, and the random variable X = 210.

To find the probability that more than 210 people will pass in front of his store, we will find P(X > 200).

P(X > 200) = 1 - P(X ≤ 210).

Now, P(X ≤ 210) can be calculated using the function poissoncdf(200,210) on the calculator.

As to find the probability of a Poisson Distribution P(X ≤ x), for a mean = λ, we use the calculator function poissoncdf(λ,x).

The value of poissoncdf(200,210) = 0.77271.

Thus, the value of P(X > 210) = 1 - 0.77271 = 0.22729.

Thus, the probability that more than 210 people will pass in front of his store is 0.2272.

The arc length of the given arc is 7π cm. The correct answer is e) 7π cm.

To find the arc length of an arc, you can use the formula:

s = θ * r

Where:
s is the arc length,
θ is the central angle in radians, and
r is the radius.

In this case, the central angle θ is given as 315∘. To use the formula, we need to convert this angle to radians. Remember that 180∘ is equal to π radians.

To convert 315∘ to radians, we can use the conversion factor:

π radians / 180∘

So, 315∘ is equal to:

315∘ * (π radians / 180∘) = 7π/4 radians

Now we can substitute the values into the formula:

s = (7π/4) * 4 cm

Simplifying the equation, we have:

s = 7π cm

Therefore, the arc length of the given arc is 7π cm.

The correct answer is e) 7π cm.

a. To represent the garden's width, w, in terms of its length, I, we can use the equation:

w = 300 - 2I

The width is equal to the remaining fence length (300 feet) after subtracting twice the length (2I) because the rectangular planter has two equal sides and two equal ends.

b. To define a function g that represents the rose garden's area in terms of its length, l, we can use the equation:

The sample space for the number solid is {1, 2, 3, 4, 5, 6} and the probability of rolling 1 is 1/6.

The sample space refers to the set of all possible outcomes of an experiment, while a sample value is a specific outcome in the sample space.

For the given 8-sided solid, the sample space would be {1, 2, 3, 4, 5, 6}, as the faces labeled "skip" are not counted as sample values.

Now, let's calculate the probability of rolling a 1. Probability is the likelihood of a particular outcome occurring, which can be calculated by dividing the number of successful outcomes (in this case, rolling a 1) by the total number of possible outcomes.

The total number of possible outcomes is 6 (1, 2, 3, 4, 5, and 6). There is only one successful outcome: rolling a 1.

So, the probability of rolling a 1 is:

P(1) = (Number of successful outcomes) / (Total number of possible outcomes)
P(1) = 1 / 6

Thus, the probability of rolling a 1 on this 8-sided solid is 1/6 or approximately 0.1667, or 16.67%.\
