The simplified expression is equal to 2/3.

        2m⁰ * n⁶ / (3n⁵)

       2 * n⁶ / (3n⁵)

        2 * n / (3n) = 2/3

So the simplified expression is equal to 2/3.

The rules of arithmetic and exponentiation that I used to simplify the expression are general mathematical principles that are applicable to many mathematical problems. However, the specific techniques for simplifying an expression will depend on the particular expression and the context in which it is being used.

For example, there might be additional rules or simplification techniques that are specific to a particular field of mathematics, such as algebra, calculus, or geometry. In these cases, it's important to understand the specific rules and techniques that apply to the problem at hand in order to simplify an expression effectively.

In general, the goal of simplifying an expression is to make it easier to understand and manipulate mathematically, either for further calculations or for understanding the relationships between the variables involved.

The Mean, Variance, Standard Deviation, and Coefficient of Variation for the given sample of the number of severe car accidents in 1-90 from 2015 to 2020 are:

Mean = 224.833

Variance = 1956.0667

Standard Deviation (SD) = 108.319

Coefficient of Variation (CV) = 48.163%

From the question above, Given data is: 256, 189, 172, 220, 320, 192

Mean, variance, standard deviation and coefficient of variation for the given sample of the number of severe car accidents in 1-90 from 2015 to 2020 are given below:

The mean of data is equal to the sum of all data points divided by the total number of data points.

N = 6

Sum of data = 256 + 189 + 172 + 220 + 320 + 192 = 1349 ∴ Mean = 1349 / 6= 224.833

Calculation of Variance: The variance of data is the average of the squared differences from the mean.

Variance is calculated by dividing the sum of squared deviations by N-1, where N is the number of data points and then find the average.

Calculation of standard deviation: The standard deviation of data is the square root of the variance.SD = √11736.4 = 108.319

Coefficient of variation (CV): The coefficient of variation (CV) is a normalized measure of the dispersion of the data points. It is the ratio of the standard deviation to the mean.

CV is used to analyze and compare data of different sizes.

So, CV = (SD / Mean) × 100%CV = (108.319 / 224.833) × 100%= 48.163%∴

Answer:

x=3

6x-3 = 15

Step-by-step explanation:

The sides with the lines means they are the same length

The perimeter is

6x-3  + 6x -3  + 32 = 62

Combine like terms

12x+26=62

Subtract 26 from each side

12x+26-26 =62-26

12x =36

Divide by 12

12x/12 = 36/12

x = 3

The missing side length 6x-3 = 6*3 -3 = 18-3 = 15

The system capacity is 2 units per minute, the bottleneck stage is Stage A, and the utilization of Stage 3 is 100%.

A line process has three processing stages with the characteristics given below:

Stage A B C Unit processing time(minutes) 1 2 3 Number of machines 1 1 2 Machine availability 90% 100% 100% Process yield at stage 100% 100% 100%

To determine the system capacity and the bottleneck stage and utilization of Stage 3:

The system capacity is calculated by the product of the processing capacity of each stage:

1 x 1 x 2 = 2 units per minute

The bottleneck stage is the stage with the lowest capacity and it is Stage A. Therefore, Stage A has the lowest capacity and determines the system capacity.The utilization of Stage 3 can be calculated as the processing time per unit divided by the available time per unit:

Process time per unit = 1 + 2 + 3 = 6 minutes per unit

Available time per unit = 90% x 100% x 100% = 0.9 x 1 x 1 = 0.9 minutes per unit

The utilization of Stage 3 is, therefore, (6/0.9) x 100% = 666.67%.

However, utilization cannot be greater than 100%, so the actual utilization of Stage 3 is 100%.

Hence, the system capacity is 2 units per minute, the bottleneck stage is Stage A, and the utilization of Stage 3 is 100%.

The simplest ratio between 5 gallons and 6 quarts is 10:3.

To convert 5 gallons to quarts, we can use the conversion factor that 1 gallon is equal to 4 quarts.

Therefore, 5 gallons is equal to 5 x 4 = 20 quarts.

Now we need to express this ratio in its simplest form.

To simplify the ratio, we can divide both the number of quarts and the number of gallons by their greatest common divisor (GCD).

The GCD of 20 and 6 is 2. So, dividing both numbers by 2, we get:

20 ÷ 2 = 10

6 ÷ 2 = 3

Therefore, the simplest ratio between 5 gallons and 6 quarts is 10:3.

Answer:

x = -1, y= -5

Step-by-step explanation:

y=-x-6

y=x-4

Since both equations are equal to y we can set them equal to each other

-x-6 = x-4

Add x to each side

-x-6+x = x-4+x

-6 = 2x-4

Add 4 to each side

-6+4 = 2x-4+4

-2 =2x

Divide by 2

-2/2 = 2x/2

-1 = x

now find y

Mediante la aplicación de las razones trigonométricas y triángulos rectángulos se concluye que la altura de la colina es de aproximadamente 106.684 metros.

Tomando en cuenta toda la información disponible del enunciado podemos desarrollar el diagrama geométrico indicado en la imagen adjunta. La construcción se basa fundamentalmente en dos triángulos rectángulos con un lado común.

A continuación, la altura de la colina se determina mediante el siguiente procedimiento:

\(\frac{s'}{\sin 45.8^{\circ}} = \frac{16\,m}{\sin 13^{\circ}}\)

s' ≈ 50.991 m

x = s' · cos 13°

x = (50.991 m) · cos 13°

x ≈ 49.684 m

Finalmente, la altura de la colina es:

h = 57 m + x

h = 57 m + 49.684 m

h = 106.684 m

The midpoint Riemann sum approximation of ∫64x3 1−−−−−√ⅆx using 4 subintervals of equal width is 9980

The midpoint Riemann sum approximation of ∫64x3 1−−−−−√ⅆx using 4 subintervals of equal width is calculated by summing the area of each subinterval under the midpoint of the interval.

The formula for the midpoint Riemann sum is given by:

Sum = (width of interval) * (height of midpoint)

For this problem, since the width of each interval is 16/4 = 4, the midpoint Riemann sum is calculated by:

Sum = 4 * (1 + (16/4)^3 + (32/4)^3 + (48/4)^3)

Substituting the values for each midpoint, we get the following equation:

Sum = 4 * (1 + 4^3 + 8^3 + 12^3)

This simplifies to:

Sum = 4 * (1 + 64 + 512 + 1728)

Therefore, the midpoint Riemann sum approximation of ∫64x3 1−−−−−√ⅆx using 4 subintervals of equal width is:

Sum = 4 * (2495)

Sum = 9980

The probability of renting exactly three apartments in a week is approximately 0.2018 or 20.18%.

If the average number of units rented per week is 2.3 and the distribution is Poisson, then the parameter lambda is also equal to 2.3.

The probability of renting exactly three apartments in a week is given by the Poisson probability function:

\(P(X = 3) = (e^(-lambda) * lambda^x) / x!\)

Substituting the values, we get:

\(P(X = 3) = (e^(-2.3) * 2.3^3) / 3!\)

P(X = 3) = (0.09963 * 12.167) / 6

P(X = 3) = 0.2018

Therefore, the probability of renting exactly three apartments in a week is approximately 0.2018 or 20.18%.

The ratio of corresponding sides for the given similar triangles is 2/5.

In the given options, the ratio of corresponding sides is provided for each set of similar triangles. Let's analyze each option to determine the correct ratio:

a. 10

This option only provides a single number and does not specify the ratio of corresponding sides. Therefore, it is not the correct answer.

b. 4/5

This option provides the ratio 4/5 for the corresponding sides of the similar triangles. However, the ratio can be simplified further.

To simplify the ratio, we divide both the numerator and denominator by their greatest common divisor (GCD). In this case, the GCD of 4 and 5 is 1.

Dividing 4 and 5 by 1, we get:

4 ÷ 1 = 4

5 ÷ 1 = 5

Therefore, the simplified ratio is 4/5.

c. 10/85

This option provides the ratio 10/85 for the corresponding sides of the similar triangles. However, this ratio cannot be simplified further, as 10 and 85 do not have a common factor other than 1.
