which pair of segments in the figure below intersect?

The interval notation of the given sets of A and B are A U B : {z│z is all real Numbers (lR)} and A ∩ B : {z│4 <  z ≤ 8} (less than equal to for 8).

Sets are groups of clearly defined objects or elements in mathematics. A set is represented by a capital letter symbol, and the cardinal number of a set enclosed in a curly bracket indicates how many elements there are in a finite set.

A set can be of many different forms, such as an empty set or null set, which is one without any elements.

An illustration of a null set is A =.

It only has a finite number of components.

Instance: A = 1, 2, 3, 4.

The items of an infinite set are unbounded.

The set of all whole numbers is represented by the expression A = x.

A U B : {z│z is all real Numbers (lR)}    

∩ means and common area in both hence:

The probabilities for the standard normal distribution in r or using the standard normal table are

a) P(X<2.18) = 0.9854

b)P(X>2.18)= 0.0146

c) P(<-2.49) = 0.0064

The standard normal table is a mathematical table that allows us to know the percentage of values below the z-score (left) of the standard normal distribution. This is the "bell-shaped" curve of the standard normal distribution. It is a normal distribution with mean 0 and standard deviation 1. Using the Z-table:

Now, we have to determine the probability value for (a) , (b) and (c) .

a) P(X < 2.18) = P( Z< 2.18) = intersection point of row value 2.1 and column 0.08 = 0.9854

b) P(X >2.18) = P( Z> 2.18) = 1 - P( Z< 2.18)

= 1 - 0.9854 = 0.0146

c) P(X < -2.49) = P(Z < -2.49) = intersection point of row value -2.4 and column 0.09 = 0.0064.

Hence, we got all the required probability values.

The total payment of the family is given as $336

The family`s payment would be  $2725

The model that elates payments and charges is Payment = $250 + (1 - insurance payment percentage) * (charge - $250)

a) If the dental charge is $680, then the family's payment is:

Deductible: $250 (the family has to pay this first)

Remaining charges: $680 - $250 = $430

The insurance company pays for 80% of the remaining charges, which is 0.8 * $430 = $344

Therefore, the family has to pay for 100% - 80% = 20% of the remaining charges, which is 0.2 * $430 = $86

So, the total payment by the family is $250 + $86 = $336

b) If the dental charge is $4500, then the family's payment is:

Deductible: $250 (the family has to pay this first)

Remaining charges after deducting the deductible: $4500 - $250 = $4250

The insurance company pays for 80% of the remaining charges that do not exceed $1500, which is 0.8 * $1500 = $1200

So, the remaining charges for the family to pay after the insurance pays for the first $1500 of the remaining charges: $4250 - $1500 = $2750

The insurance company pays for 50% of the remaining charges that exceed $1500, which is 0.5 * $2750 = $1375

Therefore, the family has to pay for 100% - 50% = 50% of the remaining charges that exceed $1500, which is 0.5 * $2750 = $1375

So, the total payment by the family is $250 + $1200 + $1375 = $2725

c) The model that relates the payments and charges is:

Payment = $250 + (1 - insurance payment percentage) * (charge - $250)

where the insurance payment percentage is 80% if the charge is between $250 and $1500, and it is 50% if the charge exceeds $1500.

The ratio of the areas of the two circles equals the square of the ratio of their radii:  = 1/4

Let O1 be the center of the larger circle and O2 be the center of the smaller circle. T is the tangent point between the two circles.

The distance between their centers, O1O2, is equal to the sum of their radii, i.e., r1 + r2.

The Pythagorean theorem gives us:

(O1O2)^2 = r1^2 + r2^2

By substituting r1, r2, and O1O2 values, we obtain:

(r1 + r2)^2 = r1^2 + r2^2

By broadening and simplifying, we get:

2r1r2 = r2^2

When both sides are divided by r22, we get:

2r1/r2 = 1

So, r1/r2 = 1/2. r2 = 2r1.

The ratio of the areas of the two circles equals the square of the ratio of their radii:

A first course in differential equations with modeling applications ninth edition is a textbook that covers the basics of differential equations and their applications in mathematical modeling.

It begins with an introduction to the concepts of differential equations, including the definition, solution methods, and the concept of modeling. It then covers topics such as first-order linear equations, higher-order linear equations, systems of linear differential equations, and nonlinear equations. It also has a chapter on boundary-value problems, which is a type of differential equation that involves a set of boundary conditions that must be satisfied for the solution to be valid.

In order to solve differential equations with boundary-value problems, we must first define the boundary conditions that must be satisfied for the solution to be valid. This involves setting up the boundary conditions in terms of the dependent and independent variables of the equation. We then solve the equation using the boundary conditions and the equation itself. The solution is then used to calculate values for the independent and dependent variables at the boundary points. Finally, we can verify the solution by substituting the calculated values into the equation and seeing if the solution is valid.

The linear regression equation for this problem is y = 4.5x + 200, where y is the profit in thousands of dollars and x is the number of units sold in hundreds.

The linear regression equation for this problem is y = 4.5x + 200, where y is the profit in thousands of dollars and x is the number of units sold in hundreds.

To calculate the equation, we first need to calculate the slope and the y-intercept. Since we have 5 points, we can calculate the slope using the formula m=(y2-y1)/(x2-x1). For this problem, we'll use (46,250) and (54,410). Plugging the values into the formula, we get m = (410-250)/(54-46) = 4.5.

Next, we need to find the y-intercept, which is 200. The formula for this is b = y-mx. For our problem, we'll use (46,250). Plugging in the values, we get 200 = 250 - 4.5(46), so b = 200.

Therefore, the linear regression equation for this problem is y = 4.5x + 200, where y is the profit in thousands of dollars and x is the number of units sold in hundreds.

To find the bearing from the phone to the transmitter, we can use the arctangent function.

The formula to find the bearing is:

θ = atan2(dy, dx)

where dx = difference in x-coordinates and dy = difference in y-coordinates.

Here, dx = -13 km and dy = -21 km, since the transmitter is located to the west and south of the phone.

Therefore, the bearing is:

θ = atan2(-21, -13) = atan2(21, 13) = 63.434948822922° (to the nearest degree)

So the bearing from the phone to the transmitter is approximately 63.4°.

China would export 50 million shirts in exchange for 5 million computers (or more if they can). Trade would benefit the US since it will only need to trade 5 million computers in exchange for 50 million shirts, and it will still have 15 million computers that it can consume or trade with come other country.

Explain at what price of computers (in terms of shirts) the two countries might trade.

the minimum and maximum prices would be 5 to 10 shirts per computer. If the price of shirts per computer is 10 or near 10, then the US wins more. If the price of shirts per computer is 5 or near 5, then China wins more.

opportunity cost of producing 1 shirt in the US = 20/100 = 0.2 computers

opportunity cost of producing 1 computer in the US = 100/20 = 5 shirts

ax + b = 3x - 3a

collecting terms with x variables

b + 3a = 3x - ax

b + 3a = x(3 - a)

isolating x dividing through by (3 - a) will result to

b + 3a / (3 - a) = x(3 - a) / (3 - a)
