Since you didn't specify the desired range, you can choose the appropriate number of standard deviations based on your needs or conventions.

To determine within how many standard deviations from the mean all the values fit, you need to follow these step-by-step instructions:

Calculate the mean (average) of the given values by adding all the numbers together and dividing by the total count.

Mean = (85 + 89 + 152 + 119 + 157 + 71 + 163 + 144 + 161 + 141 + 150 + 60) / 12 = 126.58 (rounded to two decimal places)

Calculate the variance by finding the squared difference between each value and the mean, summing up all the squared differences, and dividing by the total count.

Variance = [(85 - 126.58)^2 + (89 - 126.58)^2 + ... + (150 - 126.58)^2 + (60 - 126.58)^2] / 12

Take the square root of the variance to obtain the standard deviation.

Standard Deviation = √Variance

Once you have the standard deviation, you can determine within how many standard deviations from the mean all the values fit. Generally, if a value falls within one standard deviation of the mean, it is considered close to the mean.

Remember, standard deviations are a measure of dispersion, so the range within which the values fall depends on the specific criteria or rule you want to apply (e.g., one, two, or three standard deviations).

Since you didn't specify the desired range, you can choose the appropriate number of standard deviations based on your needs or conventions.

A matrix is a rectangular array of numbers or other mathematical objects, typically arranged in rows and columns. Matrices are often denoted using capital letters, such as A, B, and C. Each element of a matrix is identified by its row and column indices,

1) False, If two row interchanges are made in succession, the determinant of the new matrix is the negative of the determinant of the original matrix.

2) False, If the determinant of a matrix is zero, it does not necessarily mean that two rows or two columns are the same or a row or column is zero, it only means that the matrix is singular, i.e. non-invertible and it also can mean that the matrix is linearly dependent.

3) False, The determinant of a matrix is not always equal to the product of the diagonal entries, it is a scalar value calculated through a specific method called matrix expansion which is based on the entries of the matrix and it depends on the size of the matrix.

4) False, The determinant of a matrix is a scalar value, it cannot be equal to another matrix.

The given expression is now written in the form of ax+b/cx-d where a, b, c, and d are integers, which is as follows:(27x³ - 12x) / (6x² - 28x) = -3x(9x² - 4) / 4(x - 7)

To write the expression in the form of \(ax+b/cx-d,\) we have to perform the given operation to obtain the same denominator.

Explanation: Given expression is: 9x²-4/6x-4 x 3x/x²-5x

First, let's factor the given denominators.6x-4 = 2(3x-2)x²-5x = x(x-5)

Now let's simplify the expression using the above factors.

9x² - 4/6x - 4 x 3x/x² - 5x

= (9x² - 4)/2(3x - 2) * 3x/x(x - 5)

Next, we will perform multiplication of the numerators and denominators of each expression.

9x² - 4/6x - 4 x 3x/x² - 5x

= [(9x² - 4) * 3x] / [2(3x - 2) * x(x - 5)]

Now, let's simplify the given expression by expanding the numerator.

9x² - 4/6x - 4 x 3x/x² - 5x = [(27x³ - 12x) / (6x² - 28x)]

Finally, let's factor out the common factor from both numerator and denominator of the expression.

9x² - 4/6x - 4 x 3x/x² - 5x = [3x(9x² - 4) / 2(3x - 2) * -2(x - 5)]

Thus, the given expression is now written in the form of ax+b/cx-d where a, b, c, and d are integers, which is as follows:(27x³ - 12x) / (6x² - 28x)

= -3x(9x² - 4) / 4(x - 7)

The solution to the equation -1/2w - 3/5 = 1/5w is w = -6/7, meaning that w equals negative six-sevenths when the equation is true.

To solve the equation -1/2w - 3/5 = 1/5w, we'll start by simplifying and rearranging the terms to isolate the variable w.

First, we'll combine like terms on the left side of the equation:

-1/2w - 3/5 = 1/5w

To make the equation easier to work with, let's get rid of the fractions by multiplying every term in the equation by the common denominator, which is 10:

10 * (-1/2w) - 10 * (3/5) = 10 * (1/5w)

This simplifies to:

-5w - 6 = 2w

Next, we'll group the w terms on one side of the equation and the constant terms on the other side:

-5w - 2w = 6

Combining like terms, we have:

-7w = 6

Now, we'll isolate the variable w by dividing both sides of the equation by -7:

(-7w)/(-7) = 6/(-7)

This simplifies to:

w = -6/7

Therefore, the solution to the equation -1/2w - 3/5 = 1/5w is w = -6/7.

In conclusion, w is equal to -6/7 when the equation -1/2w - 3/5 = 1/5w is satisfied.

Answer:

t = -5

Step-by-step explanation:

Solve for t:

5 (t - 3) - 2 t = -30

Hint: | Distribute 5 over t - 3.

5 (t - 3) = 5 t - 15:

5 t - 15 - 2 t = -30

Hint: | Group like terms in 5 t - 2 t - 15.

Grouping like terms, 5 t - 2 t - 15 = (5 t - 2 t) - 15:

(5 t - 2 t) - 15 = -30

Hint: | Combine like terms in 5 t - 2 t.

5 t - 2 t = 3 t:

3 t - 15 = -30

Hint: | Isolate terms with t to the left hand side.

Add 15 to both sides:

3 t + (15 - 15) = 15 - 30

Hint: | Look for the difference of two identical terms.

15 - 15 = 0:

3 t = 15 - 30

Hint: | Evaluate 15 - 30.

15 - 30 = -15:

3 t = -15

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of 3 t = -15 by 3:

(3 t)/3 = (-15)/3

Hint: | Any nonzero number divided by itself is one.

3/3 = 1:

t = (-15)/3

Hint: | Reduce (-15)/3 to lowest terms. Start by finding the GCD of -15 and 3.

The gcd of -15 and 3 is 3, so (-15)/3 = (3 (-5))/(3×1) = 3/3×-5 = -5:

Step-by-step explanation:

The value of X (normally distributed) such that 50% of serving times are less than X is 20.

To find the value of X such that 50% of serving times are less than X, we need to find the corresponding z-score from the standard normal distribution.

The z-score represents the number of standard deviations away from the mean, and it can be calculated using the formula:

z = (X - u) / o

where X is the value we want to find, u is the mean, and o is the standard deviation.

In this case, we want to find the value of X such that 50% of serving times are less than X. Since the normal distribution is symmetric, we can find the z-score that corresponds to the cumulative probability of 0.5, which is the same as 50%.

Using a standard normal distribution table or calculator, we can find that the z-score corresponding to a cumulative probability of 0.5 is 0.

Now we can rearrange the formula for the z-score to solve for X:

z = (X - u) / o

0 = (X - 20) / 5

Solving for X:

0 = X - 20

X = 20

Therefore, the value of X such that 50% of serving times are less than X is 20.
