Therefore, the pilot should turn by approximately 41.8 degrees to fly directly to the airport.
What is trigonometry?Trigonometry is a branch of mathematics that deals with the study of the relationships between the sides and angles of triangles. It has applications in various fields, such as engineering, physics, architecture, and astronomy. Trigonometry is based on the use of six fundamental trigonometric functions, which are sine, cosine, tangent, cosecant, secant, and cotangent. These functions are defined in terms of the ratios of the sides of a right triangle. In a right triangle, one angle is a right angle, which measures 90 degrees, and the other two angles are acute angles, which are less than 90 degrees. The three sides of a right triangle are called the hypotenuse, the adjacent side, and the opposite side. The hypotenuse is the longest side, and it is always opposite to the right angle. The adjacent side is the side that is adjacent to the angle of interest, and the opposite side is the side that is opposite to the angle of interest.
Here,
We can use trigonometry to find the angle x that the pilot should turn in order to fly directly to the airport.
First, let's draw a diagram of the situation:
A(airport)
|\
| \
| \
| \
| \
| \

P x mi
In the diagram, P represents the position of the plane, which is 148 miles north and 167 miles east of the airport A. The line labeled "x mi" represents the distance that the plane needs to fly in order to reach the airport, and the angle x is the angle between the line x mi and the line representing the eastward direction.
To find x, we can use the trigonometric ratio for tangent (tan):
tan(x) = opposite/adjacent
In this case, the opposite side is 148 miles (the distance north of the airport) and the adjacent side is 167 miles (the distance east of the airport). Therefore:
tan(x) = 148/167
Using a calculator, we can find that:
tan(x) ≈ 0.8868
To find x, we need to take the arctangent (tan⁻¹) of both sides:
x = tan⁻¹(0.8868)
Using a calculator, we find that:
x ≈ 41.8°

we know the sample size is 90. for what sample proportion would the p-value be equal to 0.05? assume that all conditions necessary for inference are satisfied.
The sample proportion would be 0.5.we can calculate the proportion by plugging in n = 90, which yields a proportion of 0.5.
To determine what sample proportion would yield a p-value of 0.05, we must first understand the formula for calculating a p-value. The formula for a p-value is p-value = 1 - [tex](1 - proportion)^n[/tex], where n is the sample size. By manipulating this equation, we can solve for the proportion when the p-value is equal to 0.05. We can isolate the proportion by taking the inverse of both sides of the equation, which yields: proportion = 1 - [tex](1 - 0.05)^(1/n)[/tex].

What is the probability that a random sample of 52 pregnancies has a mean gestation period of 222 days or less?The probability that the mean of a random sample of 52 pregnancies is less than 222 days is approximately ____. (Round to four decimal places as needed.)
The probability that the mean of a random sample of 52 pregnancies is less than or equal to 222 days is approximately 0.0005 (rounded to four decimal places).
Let's discuss it further below.
To solve the problem, we use the z-score formula, which is as follows:
z=(X−μ)/σX = sample mean = 222 days
μ = population mean = 226 days
σ = standard deviation of the population = 15 days
n = sample size = 52
To find the probability, we need to convert the sample mean to a z-score, which is calculated as follows:
z=(X−μ)/σ=(222−226)/(15/√52)=−4/2.096=−1.91
Now we need to find the probability that a random sample of 52 pregnancies has a mean gestation period of 222 days or less, which is equivalent to finding the probability that a z-score is less than or equal to −1.91.
Using a z-table or calculator, we find that the probability of a z-score being less than or equal to −1.91 is approximately 0.0005 (rounded to four decimal places).
Therefore, the answer is 0.0005.

If a bus car 1km and 2 minutes what is the m/s
the speed of the bus in meters per second is 8.33 m/s. If a bus travels a distance of 1 kilometer in 2 minutes, we can use the formula for speed to calculate its speed in meters per second (m/s).
The formula for speed is:
Speed = Distance ÷ Time
Here, the distance is 1 kilometer, which is equal to 1000 meters (since 1 kilometer = 1000 meters), and the time is 2 minutes, which is equal to 120 seconds (since 1 minute = 60 seconds).
So, we can plug these values into the formula:
Speed = 1000 meters ÷ 120 seconds
Simplifying this expression, we get:
Speed = 8.33 meters per second (rounded to two decimal places)
Therefore, the speed of the bus in meters per second is 8.33 m/s.
To put this into context, it's important to understand that speed is the rate at which an object moves, while velocity is the rate at which it moves in a specific direction. So, in this case, we have only calculated the speed of the bus, not its velocity. However, knowing the speed of the bus can be useful for a variety of applications, such as determining how long it will take to travel a certain distance, or calculating the fuel efficiency of the vehicle

two cars leave the same parking lot, with one heading north and the other heading east. after several minutes, the northbound car has traveled 6 miles, and the eastbound car has traveled 8 miles. measured in a straight line, how far apart are the two cars?
The two cars are 10 miles apart, measured in a straight line.
We can use the Pythagorean theorem to find the distance between the two cars. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides.
Let's imagine that the cars have traveled for some time, forming a right triangle where the distance between them is the hypotenuse. The northbound car has traveled 6 miles, which corresponds to the length of one of the legs of the triangle. The eastbound car has traveled 8 miles, which corresponds to the length of the other leg of the triangle. Therefore, the distance between the two cars is
distance = √(6² + 8²) = √(36 + 64) = √100 = 10 miles

for the angle measures where cos(0) = 0, sin(x) equals 1 for π/2 radians and -1 for 3π/2 radians.
cos(0) = 0 when the angle is π/2 or 3π/2 radians.
To label the corresponding points on the unit circle, we can use the following conventions:
The angle 0 radians (or 0 degrees) starts at the positive x-axis and goes counterclockwise.
The angle π/2 radians (or 90 degrees) is at the positive y-axis.
The angle π radians (or 180 degrees) is at the negative x-axis.
The angle 3π/2 radians (or 270 degrees) is at the negative y-axis.
So, for cos(0) = 0, the corresponding angle measures are π/2 and 3π/2 radians. On the unit circle, these correspond to the points (0, 1) and (0, -1), respectively.

WHAT IS COMBINATION ?
Combination refers to a mathematical concept used to count the number of ways in which a specific number of objects can be selected from a larger set, without considering their order. In other words, it is a way to calculate the number of possible combinations that can be formed from a given set of objects, where the order in which the objects are chosen does not matter. Combinations are denoted by the symbol "nCr" or "C(n,r)" and can be calculated using the formula: nCr = n!/r!(n-r)!, where n represents the total number of objects, and r represents the number of objects being chosen.
To solve this problem, we can use the combination formula. The number of ways to select k items from a set of n items is given by:
C(n, k) = n! / (k! * (n - k)!)
where n! means n factorial (i.e. n multiplied by all the positive integers less than n).
In this case, we want to select 10 employees for the dayshift and 4 employees for the night shift, out of a total of 14 employees. So the number of ways to make this assignment is:
C(14, 10) * C(4, 4) = (14! / (10! * 4!)) * (4! / (4! * 0!))
Simplifying this expression, we get:
C(14, 10) * C(4, 4) = (14 * 13 * 12 * 11) / (4 * 3 * 2 * 1) * 1
C(14, 10) * C(4, 4) = 1001 * 1
C(14, 10) * C(4, 4) = 1001
So there are 1001 ways to assign 10 employees to the dayshift and 4 employees to the night shift out of a group of 14 employe

What is dilated point?I believe you might have meant "dilated point", which is a term commonly used in geometry. A dilated point is a point that has been enlarged or reduced in size with respect to a fixed center of dilation.
To dilate a point, you need to multiply its coordinates by a scale factor, which is a constant value greater than zero. If the scale factor is greater than one, the point will be enlarged, and if it is less than one, the point will be reduced in size. The fixed center of dilation is the point about which the dilated point is enlarged or reduced.
given by the question.
To apply the dilation rule of (1/2x, 1/2y) to a given point (x,y), we need to multiply the x-coordinate and y-coordinate of the original point by 1/2.
Using this rule, we can find the dilated points for the given set of points as follows:
For the point (0,1), we have:
1/2x = 1/2 * 0 = 0
1/2y = 1/2 * 1 = 1/2
So, the dilated point is (0, 1/2).
For the point (4, -3), we have:
1/2x = 1/2 * 4 = 2
1/2y = 1/2 * (-3) = -3/2
So, the dilated point is (2, -3/2).
For the point (-6,1), we have:
1/2x = 1/2 * (-6) = -3
1/2y = 1/2 * 1 = 1/2
So, the dilated point is (-3,1).

Find the center and radius of a circle with the equation x^2 + y^2 = 20.
x 2 + y 2 = 20
This is the form of a circle. Use this form to determine the center and radius of the circle.
( x − h ) 2 + ( y − k ) 2 = r 2
Match the values in this circle to those of the standard form. The variable r represents the radius of the circle, h represents the x-offset from the origin, and k represents the y-offset from origin.
r = 2 √ 5
h = 0
k = 0
The center of the circle is found at ( h , k )
. Center: ( 0 , 0 )
These values represent the important values for graphing and analyzing a circle.
Center: ( 0 , 0 )
Radius: 2 √ 5

Answer:
The sample may be biased because the 50 people were selected at a local college baseball game, which could introduce selection bias. People attending a college baseball game may have different characteristics than the general population of the city, and therefore may not be representative of the population's opinions on the issue of building a new football stadium using tax funds. Additionally, the fact that they were selected at a baseball game may also introduce bias, as they may be more likely to be interested in sports and therefore more likely to support a tax-funded stadium. Overall, the sample may not be representative of the population's views, and therefore the conclusions drawn from the sample may not be generalizable to the entire population.

Answer:
Step-by-step explanation:
it is either Graph A or B pick one of them
Answer:
Graph D is correct
Step-by-step explanation:
if you choose a point, let's say 0,0 and plug in the values for x and y, you'll get
[tex]0 \leqslant - 2[/tex]
Since this equation isn't true, 0,0 can't be filled.
to choose between graphs c and d, you look at the line and because c is dotted, it means it isn't solution. because your sign is less than or equal to, the line has to be solid.
therefore, graph d is the correct answer
During a space shuttle launch, a maneuver is scheduled to begin at T minus 80
seconds, which is 80 seconds before liftoff. The maneuver lasts 1 1/2 minutes. At
what time will the maneuver be complete?
Therefore, since a movement is set to start at T minus 80, the move will be completed at T plus 10 seconds.
What is the order of rotation?The amount of rotations a shape can undergo around its center before returning to its initial position is referred to as the order of rotation in mathematics and geometry. It is also referred to as a shape's circular symmetry. A circle, for instance, has an order of rotation of infinite because it can be rotated indefinitely around its center without changing how it appears. A cube has an order of rotation of four because it will remain the same in shape whether it is rotated 90, 180, 270, or 360 degrees around its center.
given
At T minus 80 seconds, or 80 seconds prior to liftoff, the move is slated to start.
We must multiply the duration of the maneuver by the beginning time to determine the time at which it will be finished.
The move is estimated to take 1 and a half minutes. Since there are 60 seconds in a minute, we can change this to seconds by multiplying it by 60:
1 and a half minutes is equal to 1.5 minutes, 1.5 minutes multiplied by 60 seconds is equal to 90 seconds.
The move lasts 90 seconds as a result.
We multiply the duration of the move (90 seconds) by the start time (T minus 80 seconds) to determine the time at which the maneuver will be finished:
The move will be finished in T minus 80 seconds plus 90 seconds.
By adding the integers, we can make this simpler:
When the move is finished, the time will be T minus 80 seconds + 90 seconds + T plus 10 seconds.
Therefore, since a movement is set to start at T minus 80, the move will be completed at T plus 10 seconds.
