The likelihood that the flight will be no more than 5 minutes late would be equal to a flight that arrives between 2 hours and 2 hours and 10 minutes.
So the answer would be:
P (5 late or less) = 10 * 1/20 = 0.5
The answer is 0.5
But if we are looking for the probability of the flight that would be 10 minutes late, the likelihood of that event would be 0.25.
Final answer:
The probability that a Delta airlines flight from Cincinnati to Tampa will be no more than 5 minutes late, given that the actual flight times are uniformly distributed between 2 hours and 2 hours, 20 minutes, is 0.50.
Explanation:
The question deals with the uniform distribution of flight times and calculating the probability that a flight will be no more than 5 minutes late. Assuming flight times are uniformly distributed between 2 hours (120 minutes) and 2 hours, 20 minutes (140 minutes), the total range of flight times is 20 minutes (140 minutes - 120 minutes).
Delta airlines quotes a flight time of 2 hours, 5 minutes, which is 125 minutes. Therefore, a flight being no more than 5 minutes late means the flight time would be at most 130 minutes. To find the probability that the flight time is 130 minutes or less, we calculate the proportion of the distribution that falls within this range.
The probability that the flight will be no more than 5 minutes late is the length of the interval from 120 minutes to 130 minutes divided by the total range (20 minutes), which is (130 - 120) / 20 = 10 / 20 = 0.5. Thus, the probability is 0.50 to two decimal places.
if 2 out of every 20 ducks were banded, What percent were not banded?
if 2 were banded that means 18 out of 20 were not banded
18 divided by 20 = 0.9
so 90% were not banded
Jack is mowing a lawn that has a shed. Jack wants to know the area of the lawn he has to mow. here are the dimensions of the yard and the shed. 13x-4 length 5x withd shed is 2x+4length withd is 2x
find a polynomial that describes the area of the lawn he has to mow. i.e. find the area of the area of the shed.
We know that the formula for area is simply:
area = l w
where l is length and w is width
yard dimensions: l = 13x – 4, w = 5x
Ayard = (13x – 4) 5x = 65x^2 – 20x
shed dimensions: l = 2x + 4, w = 2x
Ashed = (2x + 4) 2x = 4x^2 + 8x
Therefore the area to mow is:
Amow = Ayard – Ashed
Amow = 65x^2 – 20x – (4x^2 + 8x)
Amow = 65x^2 – 20x – 4x^2 – 8x
Amow = 61x^2 – 28x
A six-sided rectangular box is to hold 1/2 cubic meter; what shape should the box be to minimize surface area?
A circle is an object which has the lowest surface area to volume ratio. So in this case, the shape should be like that of a circle but we cannot have a circle here because we want to form a 6 sided box. So the next thing closer to circle is a square. Hence the shape should be a square:
Answer:
square
To minimize surface area for a given volume of 1/2 cubic meter, the box should be shaped as a cube with each side measuring approximately 0.7937 meters. This cube shape offers the smallest surface area for the given volume.
Explanation:To minimize the surface area of a six-sided rectangular box with a volume of 1/2 cubic meter, it is best to make the box in the shape of a cube. This shape has the smallest surface area for a given volume. To find the dimensions of the box, let's denote the side of the cube as 's'. We know that volume V of a cube is given by V = s³. So, if the volume is 1/2 cubic meter, we have:
s³ = 1/2
s = ∛(1/2) ≈ 0.7937 meters
Each side of the cube should be approximately 0.7937 meters to achieve the minimal surface area. The surface area SA of the cube can be calculated as:
SA = 6s²
SA = 6 × (0.7937)² ≈ 3.770 meters²
Thus, a cube with sides of about 0.7937 meters will have the minimal surface area for a volume of 1/2 cubic meter.

The number of gazelles will the park have next year will be 126 if An animal park has 120 gazelles. If the population increase 5% in on year.
What is percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
It is given that:
An animal park has 120 gazelles. If the population increase 5% in on year,
= 5% of 120
= 6
= 6 + 120
= 126
Thus, the number of gazelles will the park have next year will be 126 if An animal park has 120 gazelles. If the population increase 5% in on year.

the sum of the measures of the three of a angles of triangle is 180. In a triangle, the measures of three angles are x,x-5 and x+23. What is the measure of each angle
x + x-5 + x +23 = 180
combine like terms:
3x +18 = 180
subtract 18 from each side:
3x = 162
divide both sides by 3
x = 162 / 3 = 54
Angle x = 54 degrees
Angle x-5 = 54-5 = 49 degrees
Angle x +23 = 54 +23 = 77 degrees

The length of a rectangle is given by 5t+4sqrt(t), and its height is sqrt(t), where t is time in seconds and the dimensions are in centimeters. Fine the rate of change of the area of the rectangle with respect to time when the length of the rectangle is 9 centimeters.
Answer:
11.5 cm²/s
Step-by-step explanation:
We must solve two problems to answer this question:
find the time at which the length is 9 cmfind the rate of change of area with respect to time (at that time)For the first problem, we have ...
... 9 = 5t +4√t
... 9 -5t = 4√t . . . . . subtract 5t
... 81 -90t +25t² = 16t . . . . square both sides
... 25t² -106t +81 = 0 . . . subtract 16t
... (t -1)(25t -81) = 0 . . . . factor
... t = 1 or 3.24 . . . . . . t=3.24 is an extraneous solution
_____
For the second problem, we have area (a(t)) is ...
... a(t) = length×height = (5t +4√t)(√t) = 5t^(3/2) +4t
Then the derivative is ...
... a'(t) = (3/2)(5√t) +4
and
... a'(1) = (3/2)(5√1) +4 = 11.5 . . . . . cm²/s

A graphing calculator can help solve both problems. It can help find the time at which length is 9 cm by solving ... length-9 = 0. (The nice thing here is that there is no extraneous solution.) It can compute the derivative of a function, too.

Explanation:
There are several ways to write the number 46 in mathematics. One alternative way to express the number is by using words, such as 'forty-six'. Another method is to use Roman numerals, which would be 'XLVI'. Additionally, 46 can be represented in other numerical bases; for example, in binary, it is '101110', in octal, it is '56', and in hexadecimal, it is '2E'. If we dive into mathematics, 46 can also be written as a sum of other numbers, such as 23 + 23, or a product of primes, which for 46 is 2 x 23. Lastly, 46 can be expressed in scientific notation as 4.6 x 10±, though this form is more commonly used for very large or very small numbers.

Answer:
The correct option is 1. The figure PQRS is a parallelogram, if slope of SP and RQ are both –2 and SP = RQ.
Step-by-step explanation:
The opposite sides of a parallelogram are parallel are equal.
In the quadrilateral PQRS,
PQ and RS are opposite sides.
SP and RQ are opposite sides.
The slope of two parallel lines are same.
If the slopes of SP and RQ are both –2. It means SP and RQ are parallel. It is also given that
SP = RQ
Since one pair of opposite sides are equal and parallel, therefore the another set of opposite sides is also parallel and equal.
The opposite sides are prallel and equation, so the quadrilateral PQRS is a parallelogram.
Thus correct option is 1.
The statement that proves that quadrilateral PQRS is a parallelogram is: A. The slopes of SP and RQ are both –2 and SP║RQ.
Properties of the Sides of a Parallelogram
A parallelogram is a quadrilateral having two pairs of opposite sides that are equal and parallel to each other, and also, the slopes of opposite sides of a parallelogram are the same.
