¿Qué miden el IQR y el MAD?

Answers

Answer 1

Step-by-step explanation:

El IQR se utiliza en las empresas como marcador de sus tasas de ingresos. Para una distribución simétrica (donde la mediana es igual a la bisagra media, el promedio de los cuartiles primero y tercero), la mitad del IQR es igual a la desviación absoluta de la mediana (MAD). La mediana es la correspondiente medida de tendencia central.

4) The fishing fleet left Manilow Bay when the water level reached
32 feet. At 5:00am, the depth was 27 feet. The tide rose at the rate of 1
and ½ feet per hour for the next 6 hours. The depth of the water was
measured every hour on the hour. At what time may the fleet leave?

Answers

The time the fleet may leave the Manilow Bay given the rate at which the depth rises is 9am.

What time may the fleet leave?

The fishing fleet would leave when the water level reaches 32. At 5 am, the water level is 27 feet. The water level needs to rise 6 more feet (32 - 27) before the fleet can leave.

In order to determine the time, divide 6 feet by the rate at which the tide rises. Division is the mathematical operation that is used to determine the quotient of two or more numbers.

Hours when the tide would rise 6 feet = 6 ÷ 1 1/2

6 x 2/3 = 4 hours

Add 4 hours to 5am : 5am + 4 = 9am

If it takes you 40 seconds to travel from the first floor of a building to the third floor, how long will it take to travel from the first floor to the eighth floor (at the same pace, assuming all floors have equal height)? State your answer in seconds.

Answers

Answer: 104 seconds.

Step-by-step explanation: if it takes you 40 seconds to travel from the first to the third floor, then to pass one floor it will take 13 seconds. 40 divided by 3 which is 13. you then do 13x8 to figure out the time it would take you to travel through all the floors which is 104 seconds.

40/3 = 13

13 x 8 = 104

The answer is 104.

10^2 + b^2 = 17^2

100 + b^2 = 289

The length of the side a in the given right-angled triangle is 8 units.

What is a triangle?

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

In a right-angled triangle, the sum of the squares of the smaller two sides of a right-angle triangle is equal to the square of the largest side.

The given right-angled triangle has a base of 15 units and a hypotenuse of 17 units.

Therefore,

17² = 15² + a².

a² = 17² - 15².

a = [tex]\sqrt{289 - 225}[/tex].

a = [tex]\sqrt{64}[/tex].

a = 8 units.

John Beale of Stanford, California, recorded the speeds of cars driving past his house, where the speed limit read 20 mph. The mean of 100 readings was 23.84 mph, with a standard deviation of 3.56 mph. (He actually recorded every car for a two-month period. These are 100 representative readings.) a. How many standard deviations from the mean would a car going under the speed limit be? b. Which would be more unusual, a car traveling 34 mph or one going 10 mph?

Answers

How many standard deviations from the mean would a car going under the speed limit be -1.0787

Which would be more unusual: a car traveling 10 mph

Given data:

At speed limit of 20 mph mean of 100 readings was 23.84 mph

and a standard deviation of 3.56 mph

The speed limit read 20 mph

How to find the standard deviations from the mean that the car going under the speed limit

Assuming the car going under the speed limit of 20 mph be y

such that

20 = 23.84 + y * 356

356y = 20 - 23.84

y = ( 20 - 23.84 ) / 356

y = -1.0787

How to find which is more unusual

A car traveling 34 mph: using y same as number of deviations from the mean

34 = 23.84 + 3.56y

y = ( 34 - 23.84 ) / 3.56

y = 2.8539

Meaning the car travelling at 34 mph is  2.8539 standard deviations above the mean

A car traveling 10 mph: using y same as number of deviations from the mean

10 = 23.84 + 3.56y

y = ( 10 - 23.84 ) / 3.56

y = -3.8876

Meaning the car travelling at 10 mph is 3.8876 standard deviations below the mean

From the the rule that 99.7% of the observations lie with in ±3 standard. The speed of 10 mph is outside these limits but 34 mph is within the limits. Hence we say that the car travelling 10 mph is more unusual

The coordinates of the point Q are (-7,-8) and the coordinates of point R are (-7,0). What is the distance, in units, between the point Q and point R?

Answers

The distance between the points Q and R is found to be 8 units.

What is defined as the distance formula?

Algebraic expression that provides the distances between two points as a function of their coordinates (like coordinate system).

The distance equations for points in rectangular coordinates in two- and three-dimensional Euclidean space are based on the Pythagorean theorem.A line segment can be graphed both in two-dimensional & three-dimensional coordinate planes because it has a starting and stopping point. The two-dimensional coordinate plane allows the starting and stopping points to also be labeled as two-dimensional coordinates (x₁, y₁) and (x₂, y₂), respectively, resulting in the distance formula as:                d = √(x₂ - x₁)² + (y₂ - y₁)².

Now, as per the stated question;

The coordinates of the points Q and R are given as;

Q = (x₁, y₁) = (-7,-8)

And, R = (x₂, y₂) = (-7,0)

Now, substitute the values in the distance formula;

QR = √(-7 - (-7))² + (0 - (-8))²

QR = √(0)² + (8)²

QR = 8

Therefore, the distance between the points Q and R is calculated as 8 units.

Determine slope of any line perpindicular to GH. (-1,2) (-2,-1)

Answers

Answer:

Perpendicular slope = – 1/m = -1/3 = -1/3

Step-by-step explanation:

Given the points

(-1,2)(-2,-1)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-1,\:2\right),\:\left(x_2,\:y_2\right)=\left(-2,\:-1\right)[/tex]

[tex]m=\frac{-1-2}{-2-\left(-1\right)}[/tex]

[tex]m=\frac{-1-2}{-2-\left(-1\right)}[/tex]

[tex]m=3[/tex]

We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:

slope = m = 3

perpendicular slope = – 1/m = -1/3 = -1/3

Thus, the slope of any line perpendicular to GH = -1/3
