A probability is calculated as the division of the desired number of outcomes by the total number of outcomes in the context of a problem/experiment.

The number of cars with purchase prices less than $20,000 is given as follows:

86 + 67 + 35 = 188.

Of those 188 cars, 86 had repair costs less than $10,000, hence the probability is given as follows:

p = 86/188

p = 0.4574.

The number of cars with repair costs less than $10,000 is given as follows:

Answer:

Step-by-step explanation:

the statement " 5 symbols for a 3-symbols- long pass code" in mathematics simply means 5 has a power of 3 or 5^3 = 5×5×5= 125

According to the given information, the one angle on the straight line inside a circle is 135 then the value of the x = 4 as both angles are supplementary angles.

Supplementary angles are two angles whose sum is 180 degrees. In other words, if we add the measures of two supplementary angles, the result is always 180 degrees.

When two lines intersect, they form four angles at the intersection point. If two of these angles are supplementary, they are called adjacent supplementary angles. In this case, they share a common side and a common vertex, and their non-shared sides form a straight line.

For example, if angle A and angle B are adjacent angles, and angle A measures 120 degrees, then angle B must measure 60 degrees, since 120 + 60 = 180.

If the two angles are on a straight line, then they are supplementary, meaning their sum is 180 degrees. Therefore, we can set up the equation:

135 + (11x + 1) = 180

Simplifying the left side, we get:

136 + 11x = 180

Subtracting 136 from both sides, we get:

11x = 44

Dividing both sides by 11, we get:

x = 4

Therefore, the value of x is 4.

The percentages of people taking the test who scores between 421 and 645 is: 68 %

The empirical rule, also referred to as the three-sigma rule or the 68-95-99.7 rule, is defined as a statistical rule which states that almost all observed data for a normal distribution will fall within three standard deviations (denoted by σ) of the mean or average (denoted by µ).

We are given:

Sample mean: x' = 553

standard deviation; s = 112

Thus:

x' - ns = 421

x' + ns = 645

Where n is the number of standard deviations from the mean. Thus:

553 - 112s = 421

112s = 553 - 421

112s = 132

s = 132/112

s ≈ 1

What is profit?

The extra money is left after paying your business expenses is your profit. Gross profit, operating profit, and net profit are the three primary types of profit. The cost foundation for determining profit or loss when selling a product is the price the buyer pays at the time of purchase, known as the purchase price.

To find the volume of an irregular 3D shape like Myron's pool, he needs to determine:

1. The length

2. The width

3. The depth

With those three measurements, he can plug them into the formula for volume of a rectangular prism:

Volume = Length x Width x Depth

So if the pool is:

Length = 20 ft

Width = 10 ft

Depth = 5 ft

Then the volume would be:

20 ft x 10 ft x 5 ft = 1000 cubic feet

Does this make sense? Let me know if Myron has any other questions!

The value of x in the given chords is determined as 9.

The measure of length x is calculated by applying the following formula.

Based on the angle of intersecting chord theorem, we will have the following equation.

3 (3 + x ) = 4 ( 4 + 5 )

9 + 3x = 36

collect similar terms ang solve for x;

3x = 36 - 9

3x = 27

divide both sides of the equation by 3;

3x/3 = 27/3

The height of point A is 0 feet. However, this is not the actual height of point A, as it is at the highest point on the Ferris Wheel, which is 185 feet as calculated previously.

The height of point A on the Ferris Wheel can be calculated using the sine function, as it is the vertical component of the point's position. The center of the Ferris Wheel is 100 feet off the ground, and its radius is 85 feet.

Let's denote the height of point A as h_A, which is the vertical distance from the center of the Ferris Wheel to point A.

Since point A is at the 0 radian position, it is at the highest point on the Ferris Wheel. At this point, the height of point A is equal to the sum of the radius and the center's height:

h_A = radius + center's height

h_A = 85 + 100

h_A = 185 feet

So, the height of point A off the ground is 185 feet.

To estimate the value of h_A using the sine function, we can use the fact that at any given angle θ on the unit circle, the height of the point on the circle is given by the sine of that angle multiplied by the radius. In this case, since point A is at the highest point on the Ferris Wheel, we can use the sine of 0 radians (which is 0) to estimate the height of point A:

h_A = radius * sin(0)

h_A = 85 * 0

h_A = 0

So, using the sine function, we estimate that the height of point A is 0 feet. However, this is not the actual height of point A, as it is at the highest point on the Ferris Wheel, which is 185 feet as calculated previously.

The altitude of the plane is approximately 21.65 miles.

An altitude of a triangle is a line segment through a vertex and perpendicular to (i.e., forming a right angle with) a line containing the base (the side opposite the vertex).

We have an observer on the ground (you) and a plane flying towards you. Let's call the distance between the observer and the point directly below the plane "x", and let's call the altitude of the plane "h".

At the first moment, the angle between the ground and your line of sight to the plane is 45 degrees. This means that the angle between the plane's altitude and the ground is also 45 degrees (since the plane is flying horizontally towards you). We can use trigonometry to find the value of "x" in terms of "h".

In the right triangle formed by the observer, the point directly below the plane, and the plane's altitude, we have:

tan(45) = h/x

Since tan(45) = 1, we can simplify this to:

h/x = 1

h = x

So the distance between the observer and the point directly below the plane is equal to the altitude of the plane.

One minute later, the angle between the ground and your line of sight to the plane is 60 degrees. We can use the same approach to find the new value of "x" in terms of "h".

In the right triangle formed by the observer, the point directly below the plane, and the plane's altitude, we have:

tan(60) = h/(x + 450/60)

Simplifying this, we get:

h = (x + 7.5h) * sqrt(3)

Solving for "x", we get:

x = (h / sqrt(3)) - 7.5h

Now we can substitute the value of "x" from the first moment (which is equal to the altitude of the plane) into this equation to find the altitude of the plane:

h = (h / sqrt(3)) - 7.5h

h = h(1 / sqrt(3) - 7.5)

h = 21.65 miles (rounded to two decimal places)

Therefore, the altitude of the plane is approximately 21.65 miles.

The perimeter of the right triangle is 30 units.

What is perimeter?

In geometry, perimeter refers to the total length of the boundary of a two-dimensional shape, such as a polygon or a circle. It is the sum of the lengths of all the sides of the shape.

To find the perimeter of the right triangle, we need to determine the lengths of its sides first.

Using the distance formula, we can find the lengths of the three sides of the triangle:

Side 1: From (-5, 3) to (-5, -2)

[tex]Length = \sqrt{[(3 - (-2))^2 + (-5 - (-5))^2]} = \sqrt{[5^2]} = 5[/tex]

Side 2: From (-5, -2) to (7, -2)

[tex]Length = \sqrt{[(7 - (-5))^2 + (-2 - (-2))^2]} = \sqrt{[12^2]} = 12[/tex]

Side 3: From (7, -2) to (-5, 3)

[tex]Length = \sqrt{[(-5 - 7)^2 + (3 - (-2))^2]} = \sqrt{[144 + 25]} = \sqrt{[169]} = 13[/tex]

We know that the triangle is a right triangle because two of its sides (Side 2 and Side 3) form a straight line along the x-axis, and the third side (Side 1) is perpendicular to this line.

Therefore, Side 1 is the hypotenuse, and Sides 2 and 3 are the legs of the right triangle.

To find the perimeter, we add up the lengths of all three sides:

Perimeter = Side 1 + Side 2 + Side 3 = 5 + 12 + 13 = 30

Therefore, the perimeter of the right triangle is 30 units.
