Answer:

(6.25,2.5)

Step-by-step explanation:

Just find the coordinates and divide the x and y coordinates by the scale factor.

I'll do A.

(4,3)

Divide 4 by 0.5 and 3 by 0.5.

4/0.5=2

3/0.5=1.5

So the original coordinate for A is (2,1.5).

d) there must be at least 30 trials.

\( \frac{-9 y-81}{y+9} \) simplifies to -9.

To simplify the given expression, \( \frac{-9 y-81}{y+9} \), we need to factor out the common factor of -9 from the numerator.

Factor out the common factor of -9 from the numerator.
\( \frac{-9(y+9)}{y+9} \)

Simplify the expression by canceling out the common factor of (y+9) from the numerator and denominator.
\( \frac{-9 \cancel{(y+9)}}{\cancel{y+9}} \)

The final simplified expression is -9.
\( -9 \)

\( \frac{-9 y-81}{y+9} \) simplifies to -9.

It is important to check for any restrictions on the variable y. In this case, y cannot be equal to -9, as it would make the denominator of the original expression equal to 0 and the expression would be undefined. Therefore, the simplified expression is valid for all values of y except -9.

If we chose different intervals for binning data in a frequency table can affect the level of detail, the frequency of values, and the distribution of values in each bin. It's important to choose an interval size that is appropriate for the dataset and provides meaningful insights into the data.  Here are some ways in which the frequency table could be affected.

Choosing different intervals will result in a different number of bins, which affect the detail. For example, a smaller interval size will result in more bins, which may give a more detailed view of the data.

The frequency of values in each bin will change depending on the interval size. For example, if we have a dataset with values from 0 to 100, and we choose an interval size of 10, we will have 10 bins, each with a frequency count of values falling into that range.

The distribution of values in each bin may vary depending on the interval size. For example, if we have a dataset with values ranging from 0 to 100 and we choose an interval size of 5, we may get a more detailed view of the distribution of values.

The inverse of the function is y = ( 1/5 )x - 6.

An expression, rule, or law in mathematics that establishes the relationship between an independent variable and a dependent variable. In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.

Consider the function,

y = 5x + 30

To find the inverse of the function we interchange x and y then find the equation for y.

Therefore, after interchanging x and y:

x = 5y + 30

Subtracting 30 from each side of the equation.

x - 30 = 5y + 30 - 30

x - 30 = 5y

Now, dividing the whole equation by 5

( x - 30 ) / 5 = 5y / 5

y = ( 1/5 )x - 30/ 5

y = ( 1/5 )x - 6

Therefore, the inverse of the function y = 5x + 30 is y = ( 1/5 )x - 6.

Answer:

Step-by-step explanation:

You want the value of the piecewise function for various values of x.

The first step in evaluating a piecewise function is determining which domain is applicable to the value of x you have. Then you use the corresponding function, evaluating it in the usual way.

For x = -5, the applicable domain is x < -3, so the function is ...

  h(-5) = -4(-5) -18 = 20 -18

  h(-5) = 2

For x = 0, the applicable domain is -3 ≤ x < 1, so the function is ...

  h(0) = 1

For x = 1 or 4, the applicable domain is x ≥ 1, so the function is ...

  h(1) = 1 +2 = 3

  h(4) = 4 +2 = 6

Answer:

the answer for this question is 66 ie c option .now how you will thank me?

Answer:

C

Step-by-step explanation:

The sum of the angles is 360; n represents number of sides

S = (n - 2) x 180

S = (4-2) x 180

S = 2 x 180

S = 360

Setup the equation and simplify

2x + 10 + x - 20 + x + 40 + x = 360

5x +30 = 360

5x +30 - 30 = 360 - 30

5x = 330

5x/5 = 330/5

x = 66

Using Chebyshev's Inequality, the lower bound for the number of signals that need to be sent so that the total number of errors are within 10% of the expected number of errors with at least 95% probability is 846.

Chebyshev's Inequality states that for any random variable X with finite mean μ and variance σ², the probability that X deviates from μ by more than k standard deviations is at most 1/k².

In other words,

P(|X-μ| ≥ kσ) ≤ 1/k².

In this problem, we know that the number of errors follows a Poisson distribution with a mean of 36 errors, which means that the mean and variance are both 36.

Let X be the total number of errors in n signals. We want to find the smallest value of n such that

P(|X-μn| ≥ 0.1μn) ≤ 0.05,

where μn = nμ is the expected number of errors in n signals.

Using Chebyshev's Inequality, we have

P(|X-μn| ≥ 0.1μn) ≤ σ²/[0.1²μn²] = σ²/[0.01μ²n²] = 1/25,

where σ² = 36 is the variance of X.

Therefore, we need to solve the inequality

1/25 ≤ 0.05,

which implies n ≥ 846. Hence, the lower bound for the number of signals that need to be sent is 846.

When eight weavers are employed, and output is 80 baskets, labor productivity is equal to 10 baskets.

A labor productivity measure is a way of estimating the amount of output generated per unit of labor.

The following formula is used to calculate labor productivity:

                               Total output produced / Total number of workers involved in the production.  

Therefore, in this case, labor productivity will be equal to the total output produced divided by the total number of weavers employed.

Mathematically, Labor productivity = Total output produced / Total number of weavers employed

Given,The number of weavers employed, n = 8Output produced, Y = 80 baskets

Substitute the above values into the formula for labor productivity,

                        Labor productivity = Total output produced / Total number of weavers employed

                                                   = 80 / 8= 10

The value of the expression tan(-5π/6) can be determined using trigonometric properties and  identities.

First, let's consider the unit circle. The angle -5π/6 is measured in the clockwise direction from the positive x-axis. In this position, the reference angle is π/6, which is the positive angle formed with the x-axis.

The tangent function (tan) is defined as the ratio of the sine (sin) of an angle to the cosine (cos) of the angle. Using the reference angle π/6, we can determine the value of tan(π/6) as the ratio of sin(π/6) to cos(π/6). sin(π/6) equals 1/2, and cos(π/6) equals √3/2. Therefore, tan(π/6) is (1/2) divided by (√3/2), which simplifies to 1/√3 or √3/3. Since tan is an odd function, tan(-5π/6) is equal to the negative of tan(5π/6). Therefore, tan(-5π/6) has the same value as -√3/3.

In conclusion, the value of tan(-5π/6) is -√3/3, which means that the tangent of the angle -5π/6 is negative and equal to the ratio of -√3 to 3.

The observation is located to the left of the mean by a distance of 1.2 standard deviations.

The z-score of an observation represents the number of standard deviations the observation is away from the mean.

If the z-score for a particular observation is z = -1.2, this means that the observation is 1.2 standard deviations below the mean.

If the mean is represented by μ and the standard deviation by σ, then we can express this observation as:

observation = μ + (z * σ)

observation = μ + (-1.2 * σ)

This means that the observation is located to the left of the mean by a distance of 1.2 standard deviations.

For example, The z-score represents the number of standard deviations an observation is above or below the mean of the distribution.

In this case, a z-score of -1.2 indicates that the observation is 1.2 standard deviations below the mean height of the group.

Component 3 must be started on day 197 to meet the delivery date of day 200.

To illustrate the backward schedule, we need to start from the delivery date (day 200) and work our way backward, taking into account the lead times and dependencies of each operation.

(a) Backward schedule:

Operation    |  Work Center  |  Time (hours)  |  Start Day

--------------------------------------------------------

Final Assembly |   Work Center 1  |        1       |     200

Sub-assembly 1 |   Work Center 2  |        2       |     199

Component 4     |   Work Center 3  |        3       |     197

Component 2     |   Work Center 4  |        4       |     196

Component 3     |   Work Center 5  |        3       |     ????

(b) To identify when component 3 must be started to meet the delivery date, we need to consider its dependencies and lead times.

From the backward schedule, we see that component 3 is required for sub-assembly 1, which is scheduled to start on day 199. The time required for sub-assembly 1 is 2 hours, which means it should be completed by the end of day 199.

Since component 3 is needed for sub-assembly 1, we can conclude that component 3 must be started at least 2 hours before the start of sub-assembly 1. Therefore, component 3 should be started on day 199 - 2 = 197 to ensure it is completed and ready for sub-assembly 1.

Hence, component 3 must be started on day 197 to meet the delivery date of day 200.
