Answer: The answer is b and c

Step-by-step explanation:

The measures of central tendency are Mean: 22.14, Median: 22.00, Mode: 22.00, and dispersion are Range: 32, Variance: 183.14, Standard deviation: 13.53 Interquartile range: 12.00

According to the question

The mean, median, and mode values for this collection of data are 22, 14, and 22, respectively. The median is the midway value when the data are arranged, while the mode is the value that occurs the most frequently. The mean is the average of the data set. Range = 32, Variance = 183.14, Standard deviation = 13.53, and Interquartile Range = 12.00 are the metrics of dispersion for this data set. The variance measures the spread of the data, the standard deviation is the square root of the variance, and the interquartile range is the difference between the median of the upper half and the median of the lower half of the dataset. The range is the difference between the highest and lowest values.

The solution matrix x is [-15 15].

Without any additional information, matrix representations of linear mappings allow for explicit computations in linear algebra.

We can use the properties of matrices and vectors to simplify the equation.

First, we know that Au = a and Av = b, so we can substitute these equations into our original equation:

Ax = -5Au + 5Av

Now we can substitute in the values of u and v that we know:

Ax = -5[3 -3] + 5[-5 3]

Which simplifies to:

Ax = [-15 15]

So x = [-15 15] is a solution to the equation Ax = -5a + 5b.

Correct question :

Let A be a 3x2 matrix. Suppose we know that u = [3 -3] and v = [-5 3] satisfy the equations Au = a and Av = b. Find a solution matrix x to Ax = -5 a + 5 b.

Answer:

13.5

Step-by-step explanation:

y=kx

k=y/x

k=9/2

k=4.5

y=kx

y=4.5*3

y=13.5

The value of x in the angles is 10.

The sum of the measures of angle S and angle T is 120 degrees. Therefore, the measure of the angles are as follows:

Therefore, the value of a can be found as follows;

∠S + ∠T = 120

∠S = 8x + 5  degrees

∠T = 35 degrees

Therefore,

8x + 5 + 35 = 120

8x + 40 = 120

8x  = 120 - 40

8x = 80

divide both sides by 8

x = 80 / 8

x = 10

Therefore,

x = 10

Step-by-step explanation:

None of the above.

A measure of dispersion is a statistical technique for extracting a particular value from a dispersed series in which the amount to which different values of the series tend to deviate from one another or from the average is quantified. All dispersion measurements, from range to standard deviation, are positive.

Answer:

-8mph

It is not possible for Sarah to have a speed of -8 mph, as speed is a scalar quantity and cannot be negative. Speed is defined as the magnitude of velocity, which is a vector quantity that has both magnitude and direction. A negative speed would indicate that the direction of Sarah's motion is opposite to what is stated. It is likely that you meant to ask about Sarah's velocity, which could be -8 mph. But since the question does not specify her direction, it is impossible to give an accurate answer.

Step-by-step explanation:

The triangle ΔABC is the right-angle triangle. Then the measure of angle ∠A is 33.7°.

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.

Trigonometric functions examine the interaction between the dimensions and angles of a triangular form.

The triangle ΔABC is the right-angle triangle in which angle ∠C is the right angle.

Then the measure of the angle ∠A is given as,

tan ∠A = 2/3

∠A = tan⁻¹ (2/3)

∠A = 33.7°

Thus, the measure of angle ∠A is 33.7°.

1)Therefore the wing area is determined as 5511 ft2 2) The elliptic chord length is 35.87 f t 3) The Reynolds number for the given elliptical wing is 1.672 X 10^8 4) So, the speed of the plane is 733.33 f t/s.

1) Wing Area  

Wing Area determined by using the wingspan and aspect ratio of the Boeing. Where the Aspect ratio of the wing written as,
AR=S^ 2/A
Here s is the wingspan, A is the Wing area and AR is the Aspect ratio.
A=S^ 2/AR=195.7^ 2/6.5=5510.57 FT^ 2
Therefore the wing area is determined as 5511 ft2


2) Average Elliptical chord

Elliptic chord of the Boeing wing determined by the elliptical wing Aspect
ratio,
AR=4xspan/π x chord
chord=4x span/π x AR
chord=4x 195.7/πx6.95=35.87f t
Therefore, the elliptic chord length is determined as35.87 f t


3) Reynolds Number
Reynolds number for the given wing is determined by the average speed and the average chord length
Re=9324xVxc
Here V is the average speed and c is the chord length using the determined values we can find the Reynolds number as,
Re=9324x500x35.87=1.67225x10^ 8
Therefore, the Reynolds number for the given elliptical wing is 1.672 X 10^8


4) Cruise Speed

Where the Speed of the cruise is given as 500 mph to convert the speed mph into the f t/s,
Speed=500x5280/3600=733.33 f t/s
Here 1 mile = 5280 f t and 1 hour = 3600 seconds

So, the speed of the plane is determined in the f t/s as 733.33 f t/s.

Answer:

13,093 years

Step-by-step explanation:

N = N0 e -kt . Here, N = 27 % of N0  = 27/100(N0 ) , k = 0.0001, then 27/100N0 = N0 e-0.001t .

Therefore, 0.27 = e-0.001t .On taking natural logarithms of both the sides, we get - 0.001t ln e = ln 0.27 ( log ab = b log a), or,  - 0.001t = -1.30933332 ( as ln e = 1).

Therefore, t = 1.30933332/ 0.0001 = 13093.33 years = 13093 years on rounding off to the nearest year.

The percentage change from 20 to 14 is 30% decrease

From the question, we have the following parameters that can be used in our computation:

20 to 14

The final value (14) is less than the initial value (20)

So, the change is a percentage decrease

The change is then calculated as

Change = (Final value - Initial value)/Initial value * 100%

Substitute the known values in the above equation, so, we have the following representation

Change = (14 - 20)/20 * 100%

Evaluate

Change = -30%

Answer: The slope of a line perpendicular to y = -5x - 1 is 5, as the slopes are negative reciprocals of each other. To find the equation of a line passing through the point (10, 3), we can use the point-slope form of a line, which is:

y - y1 = m(x - x1)

where (x1, y1) is the point the line passes through, m is the slope of the line, and y and x are the variables representing the coordinates of a point on the line.

Plugging in the given values:

y - 3 = 5(x - 10)

Simplifying, we get:

y = 5x - 25 + 3

y = 5x - 22

So the equation of the line is y = 5x - 22

The number that gives a result of −4 when 8 is subtracted from the quotient of the number and 4 is: 16.

The quotient of two numbers is the result obtained when one number is divided by the other. It is the number of times one number can be divided into the other. For example, if you divide 20 by 4, the quotient is 5, meaning that 4 can be divided into 20 five times. It is represented mathematically as: quotient = numerator/denominator.

Let x represent the number. Therefore, you can find this number by solving the equation:

(x/4) - 8 = -4

(x/4) = -4 + 8

x/4 = 4

x = 4 * 4 = 16
