srry need the points
A phone receives signals from a transmitter that is 13 km west and 21 km south of it.
What is the bearing from the phone to the transmitter?
Give your answer to the nearest degree.
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°.
find the following probabilities for the standard normal distribution in r or using the standard normal table. note i always recommend drawing the distribution. (round your answers to four decimal places.)
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:
Go to the row representing the ones place and the first decimal place (10's place) of the Z-score.Go to the column that represents the second decimal place (100ᵗʰ) of the z-score.Cross the rows and columns from steps 1 and 2. This result represents the probability that the random variable Z is less than the value Z, that is p(Z < z).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.

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.

For each country, graph of computer the production possibilities frontier. Suppose that without trade the workers in each country spend half their time producing each good. Identify this point in your graphs.
Who has the comparative advantage in the production of shirts? What about for computers?
China has the comparative advantage in the production of shirts, while the US has the comparative advantage in the production of computers.
If these countries were open to trade, which country would export shirts? Give a specific numerical example and show it on your graphs. Which country would benefit from trade?
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
opportunity cost of producing 1 shirt in China = 10/100 = 0.1 computers
opportunity cost of producing 1 computer in China = 100/10 = 10 shirts
without trade:
total production of shirts in the US = 50 million
total production of computer in the US = 10 million
total production of shirts in China = 50 million
total production of computer in China = 5 million

circles of radii , and are mutually externally tangent, where and are relatively prime positive integers. find
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.

For the following exercise, consider this scenario: The profit of a company increased steadily over a ten-year span. The following ordered pairs show the number of units sold in hundreds and the profit in thousands of over the ten year span, (number of units sold, profit) for specific recorded years: (46, 250), (48, 305), (50, 350), (52, 390), (54, 410). Use linear regression to determine a function y, where the profit in thousands of dollars depends on 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.
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.
