There are 108 flights from an airport, 20 of which are longer than 3 hours. The flight from this airport will be randomly chosen. What is the probability it is longer than 3 hours? Enter your answer as a fraction, in simplest form, in the box.
The required solution of the probability it is longer than 3 hours is 5/27.
What is probability?
probability is the ratio of the number of favorable outcomes and the total number of possible outcomes. The chance that a particular event (or set of events) will occur expressed on a linear scale from 0 (impossibility) to 1 (certainty), also expressed as a percentage between 0 and 100%.
Given:
There are 108 flights from an airport, 20 of which are longer than 3 hours.
According to given question we have
By the use of probability we get,
the probability it is longer than 3 hours
=20/108
By simplifying we get
=5/27
Therefore, the required solution of the probability it is longer than 3 hours is 5/27.

The acceleration due to gravity is the constant of variation. What is the acceleration due to gravity of a falling object? 4.9 9.8 10.2 19.6
Final answer:
The acceleration due to gravity on Earth is approximately 9.80 m/s² and is symbolized as g, which represents a constant rate of acceleration for free-falling objects in the absence of air resistance.
Explanation:
The acceleration due to gravity is a constant that plays a fundamental role in physics, particularly when discussing free-fall motion. On Earth, the acceleration due to gravity of a falling object, when air resistance is negligible, is approximately 9.80 m/s². This value, denoted by the symbol g, is used to calculate various parameters in the kinematic equations of motion for an object subject only to the force of gravity.

There are 19.6.grams of protein in 4 ounces of cashews. About how many gram of protein are in one ounce of cashews?
Final answer:
To find the protein content in one ounce of cashews, divide 19.6 grams by 4 ounces, resulting in approximately 4.9 grams of protein per ounce.
Explanation:
To find out how many grams of protein are in one ounce of cashews, we need to divide the total amount of protein by the number of ounces. Given that there are 19.6 grams of protein in 4 ounces of cashews, we can calculate the amount of protein in one ounce by performing the following calculation:
Amount of protein in one ounce = Total grams of protein / Number of ounces
Amount of protein in one ounce = 19.6 grams / 4 ounces
Amount of protein in one ounce = 4.9 grams
Therefore, there are approximately 4.9 grams of protein in one ounce of cashews.

b. –0.49x^2–1.4xy –y^2
The value of equation A = - ( 5c - 0.4d )²
The value of equation B = - ( 0.7x + y )²
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the first equation be represented as A
Now , the value of A is
A = 4cd - 25c² - 0.16d² be equation (1)
On simplifying the equation , we get
A = - ( 25c² - 4cd + 0.16d² )
On factorizing the equation , we get
A = - ( 5c - 0.4d )²
Therefore , the value of A is - ( 5c - 0.4d )²
Let the second equation be represented as B
Now , the value of B is
B = -0.49x² - 1.4xy - y² be equation (1)
On simplifying the equation , we get
B = - ( 0.49x² + 1.4xy + y² )
On factorizing the equation , we get
B = - ( 0.7x + y )²
Therefore , the value of B is - ( 0.7x + y )²
Hence , the equations are solved

If a ship sailed due south from Iceland to Antarctica, it would sail through an angel of rotation of about 140° around Earths center. Find this measure in radians. Then , using 3960 miles for earth radius, find how far the ship would travel.
To convert the angle in degrees to radians, multiply the angle by π and divide by 180. The ship would travel approximately 3081.23 miles.
Explanation:To find the measure in radians, we need to convert the given angle from degrees to radians. There are 2π radians in a full circle, which is equal to 360°. Therefore, to convert 140° to radians, we can use the formula: radians = (degrees × π) / 180. Substituting the given angle, we get: radians = (140 × π) / 180 = (7π / 9) radians.
Next, to find how far the ship would travel, we need to calculate the arc length. The formula for the arc length of a circle is: arc length = radius × angle in radians. Given that the radius of Earth is 3960 miles and the angle of rotation is (7π / 9) radians, we can calculate the arc length as follows: arc length = 3960 × (7π / 9) ≈ 3081.23 miles.

Assuming that a sample (n = 504) has a sample standard deviation of 2.26, what is the upper bound of a 95% confidence interval if the sample mean is 2.96?
The upper bound of a 95% confidence interval if the sample mean is 2.96 is 3.16.and this can be determined by using the formula of standard error and margin of error.
Given :
Assuming that a sample (n = 504) has a sample standard deviation of 2.26.95% confidence interval.The sample mean is 2.96.First, evaluate the standard error by using the below formula:
[tex]\rm SE = \dfrac{\sigma}{\sqrt{n} }[/tex]
Now, put the values of n and [tex]\sigma[/tex] in the above equation in order to determine the standard error.
[tex]\rm SE = \dfrac{2.26}{\sqrt{506} }[/tex]
SE = 0.10
In order to determine the margin of error multiplies the standard error by 2.
ME = 0.1 [tex]\times[/tex] 2
ME = 0.20
Now, add the margin of error and the sample mean in order to evaluate the upper bound.
= 2.96 + 0.20b
= 3.16
The upper bound of a 95% confidence interval if the sample mean is 2.96 is 3.16.
