The mean, median, range, and standard deviation  for the new data set must all be 7 greater than for the original data set.

The mean is the sum of all the values divided by the number of values. Adding the number 6 to the original data set of 30 positive integers increases the sum of all the values by 6, which means the mean for the new data set must be 7 greater than the mean for the original data set.

The formula for the mean is: Mean = (Sum of Values)/(Number of Values)

For the original data set: Mean = (Sum of Values)/30

For the new data set: Mean = (Sum of Values + 6)/31

Therefore, the mean for the new data set must be 7 greater than the mean for the original data set.

The median is the middle value in a set of data. Adding the number 6 to the original data set of 30 positive integers increases the total number of values to 31, which means the median is calculated differently for the new data set than the original data set. The median for the new data set must be 7 greater than the median for the original data set.

The formula for the median is: Median = (n+1)/2

For the original data set: Median = (30+1)/2 = 15.5

For the new data set: Median = (31+1)/2 = 16.5

Therefore, the median for the new data set must be 7 greater than the median for the original data set.

The range is calculated by subtracting the smallest value from the largest value in a data set. Adding the number 6 to the original data set of 30 positive integers increases the largest value by 6, which means the range for the new data set must be 7 greater than the range for the original data set.

The formula for the range is: Range = (Largest Value) - (Smallest Value)

For the original data set: Range = (Largest Value) - 13

For the new data set: Range = (Largest Value + 6) - 13

Therefore, the range for the new data set must be 7 greater than the range for the original data set.

The standard deviation is a measure of how spread out the values in a data set are. Adding the number 6 to the original data set of 30 positive integers increases the total number of values by 1, which means the standard deviation for the new data set must be 7 greater than the standard deviation for the original data set.

The formula for the standard deviation is: Standard Deviation = √ (Sum of (Values - Mean)2 / Number of Values)

For the original data set: Standard Deviation = √ (Sum of (Values - Mean)2 / 30)

For the new data set: Standard Deviation = √ (Sum of (Values - Mean)2 / 31)

Therefore, the standard deviation for the new data set must be 7 greater than the standard deviation for the original data set.

The mean, median, range, and standard deviation for the new data set must all be 7 greater than for the original data set

Answer:

The index notation of 4^4 (4 raised to the power of 4) is written as 4^4 = 256.

Step-by-step explanation:

In mathematics, an exponent is a symbol indicating the number of times a quantity is multiplied by itself. In index notation, the number being raised to a power is written as the base and the power it's being raised to is written in superscript. So, in this case, 4 is being raised to the power of 4, which means 4 is being multiplied by itself 4 times. So, 4 * 4 * 4 * 4 = 256.

After the shutdown, the hospital will maintain 126 acute hospital beds available for usage.

Hospitals are classified as general, specialist, or government facilities by the source of their funding. In a medical center, nursing education and patient care are both integrated. A care facility which is smaller than a hospital is called a clinic.

If 28% of the hospital's acute card beds are going to ever be closed, that leaves 100% - 28% = 72% of such beds available for utilization.

72% of 175 beds = 0.72 x 175 = 126 beds

It is true when a scientific name appears more than once in the text, it is appropriate to write both the genus and species name the first time and then abbreviate the genus name every time after that.

Binominal nomenclature, also referred to as binary nomenclature or binomial nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, though they can be based on words from other languages. Binomial nomenclature is also known as the "two-term naming system" or "two-name naming system" and is used in taxonomy.

A name of this type is known as a binomial name (which is also abbreviated to just "binomial"), a binomen, a binominal name, or a scientific name. It was also known as a Latin name unofficially at one point in time.

The name's second component, the specific name or particular epithet, differentiates the species within the genus while the first component, the generic name, specifies the genus to which the species belongs.

Bias refers to whether an estimator tends to overestimate or underestimate a parameter, while variance refers to how much the estimate varies from sample to sample.

Bias is a measure of the difference between an estimator's expected value and the true value of the parameter being estimated. An estimator is said to be biased if it systematically overestimates or underestimates the parameter. Variance is a measure of how much the estimate of the parameter varies from sample to sample. High variance implies that the estimator is not consistent and can be unreliable. Low variance implies that the estimator is consistent and reliable. Therefore, it is important to consider both bias and variance when assessing the quality of an estimator. Bias and variance work together to form the overall accuracy of an estimator, and so it is important to consider both when evaluating the performance of an estimator.

The required standard deviation of the given data is 54.6.

To find the sample standard deviation for the weights of the offensive linemen, we first need to calculate the mean of the sample and then use that to find the variance and standard deviation.

Mean:

The mean (μ) is the sum of all the values in the sample divided by the number of values in the sample. In this case, the mean is:

(359 + 297 + 350 + 254 + 312 + 250 + 359 + 253 + 254 + 326 + 254 + 331) / 12 = 298.75

Variance:

The variance (σ²) is a measure of the spread of the data. It is calculated as the sum of the squared deviations of each value from the mean divided by the sample size minus one. In this case, the variance is:

( (359 - 298.75)² + (297 - 298.75)² + (350 - 298.75)² + (254 - 298.75)² + (312 - 298.75)² + (250 - 298.75)² + (359 - 298.75)² + (253 - 298.75)² + (254 - 298.75)² + (326 - 298.75)² + (254 - 298.75)² + (331 - 298.75)² ) / (12 - 1) = 2987.5

Standard Deviation:

The standard deviation (σ) is the square root of the variance. In this case, the standard deviation is:

√2987.5 = 54.59

Therefore, the sample standard deviation of the weights of the offensive linemen is 54.59 pounds.

The 13-digit RFC number is composed of the prefix (6601), the date of birth (XY), and the homoclave (calculated using the 10-digit RFC).

The RFC (Registro Federal de Contribuyentes) number is a unique identifier that is assigned to taxpayers in Mexico. The 13-digit RFC number is composed of several components. The first four digits, "6601," are the fixed prefix assigned to all Mexican taxpayers. The next six digits represent the date of birth of the taxpayer, in the format of "YYMMDD," so the last two digits of your ID number (XY) would represent the day of birth. The last three digits are a homoclave, a three-digit code that is assigned based on an algorithm and a verification digit. The calculation for the homoclave starts with the concatenation of the first ten digits of the RFC and then applying the following formula:

(11-(∑(D1x4 + D2x3 + D3x2 + D4x7 + D5x6 + D6x5 + D7x4 + D8x3 + D9x2))mod11)mod10

where D1-D9 are the first nine digits of the RFC. The result of the formula is the last three digits of the RFC, the homoclave. In summary, the 13-digit RFC number is composed of the prefix (6601), the date of birth (XY), and the homoclave (calculated using the 10-digit RFC).

What is the parametric equation?

The parametric equation of a curve is a representation of the curve in terms of one or more independent variables (known as parameters), usually represented as t. Each parameter value t corresponds to a unique point (x, y, z) on the curve.

For the given curve, the intersection of the cylinder x²  + y² = 81 and the surface z = 6xy can be found by setting the equation of the cylinder equal to the equation of the surface and solving for x, y, and z in terms of a single parameter t.

Starting with the cylinder: x²  + y² = 81, we can parameterize x and y as follows:

x(t) = 9cos(t)

y(t) = 9sin(t)

Substituting these expressions into the equation of the surface:

z(t) = 6x(t)y(t) = 6 * 9cos(t) * 9sin(t) = 54sin(t)cos(t)

So, the parametric equations of the curve given by the intersection of the cylinder x² + y² = 81 and the surface z = 6xy are:

x(t) = 9cos(t)

y(t) = 9sin(t)

z(t) = 54sin(t)cos(t)

The answer is:

a) The following formula must be used to get the mean and standard deviation for each flower variety:

Mean is the average of all values (number of values)

Sqrt((sum of squared deviations from the mean) / (number of values - 1)) is a formula for calculating standard deviation.

We have the following information on the first variety:

6.2, 6.3, 5.8, 6.4, 6.0, 6.9, 6.7, 6.1, 6.5, 6.4

Mean = (6.2 + 6.3 + 5.8 + 6.4 + 6.0 + 6.9 + 6.7 + 6.1 + 6.5 + 6.4) / 10 = 6.35

6.2 - 6.35 = -0.15

6.3 - 6.35 = -0.05

5.8 - 6.35 = -0.55

6.4 - 6.35 = 6.2 - 6.35 = -0.15

6.3 - 6.35 = -0.05

5.8 - 6.35 = -0.55

6.4 - 6.35 = 0.05

6.0 - 6.35 = -0.35

6.9 - 6.35 = 0.55

6.7 - 6.35 = 0.35

6.5 - 6.35 = 0.15

6.4 - 6.35 = 0.05

We now square each deviance and add them all up:

[tex]((-0.15)^2 + (-0.05)^2 + (-0.55)^2 + (0.05)^2 + (-0.35)^2 + (0.55)^2 + (0.35)^2 + (-0.25)^2 + (0.15)^2 + (0.05)^2) = 1.15[/tex]

The square root is then calculated by dividing the number of values by the number minus one:

Sqrt(1.15 / 9) 0.38 is the standard deviation.

As a result, for the first flower variety, the mean and standard deviation are 6.35 and 0.38, respectively.

b) We have the following information for the second variety: 5.1, 5.4, 5.1, 5.8, 5.0, 5.6, 5.7, 5.3, 5.5, 5.2

Mean = (5.1 + 5.4 + 5.1 + 5.8 + 5.0 + 5.6 + 5.7 + 5.3 + 5.5 + 5.2) / 10 = 5.43

To  find the deviations from the mean for each number, we must first compute the standard deviation:

5.1 - 5.43 = -0.33

5.4 - 5.43 = 0.03

5.1 - 5.43 = -0.33s

5.8 - 5.43 = 0.37

5.0 - 5.43 = -0.43

5.6 - 5.43 = 0.17

5.7 - 5.43 = 0.27

5.3 - 5.43 = -0.13

5.5 - 5.43 = 0.07

5.2 - 5.43 = -0.

Answer:

A(-3, 4) reflected across x-axis ==>  A'(-3, -4)
A'(-3, -4)  reflected across y-axis ==> A"(3, -4)

Graph attached

Step-by-step explanation:

The point is (-3, 4) shown as point A on attached graph

When reflected across the x-axis to point A' the x-coordinate does not change but the y-coordinate is the negative of the original y-coordinate

Therefore A (-3, 4)  ⇒ A' (-3, -4)

When A' is reflected across the y-axis  to A" the x-coordinates change sign but y-coordinates stay unchanged

A'(-3, -4) ⇒ A" (3, -4)

So the final point is A"(3, -4)

[10 , 44) is the interval of the number of times, Jordan need to visit his parents each year to attain Gold status.

Interval notation is a method to represent an interval on a number line. In other words, it is a way of writing subsets of the real number line. An interval comprises the numbers lying between two specific given numbers.

Given,

To qualify for gold status

one must fly at least 7000 and less than 30800 miles each year.

Jordan takes 700 miles trip to visit his parents.

No. of trips to fly at least 7000 miles = 7000/700 = 10 trips

No of trips to fly 30800 miles = 30800/700 = 44 trips.

If no. of trips is x, Jordan should take {x | 10 ≤ x < 44} trips.

An equation is a mathematical statement that proves two mathematical expressions are equal in algebra, and this is how it is most commonly used. In the equation 3x + 5 = 14, for instance, the two expressions 3x + 5 and 14 are separated.

find value of x and y :

x= 1+4t-t²

Substitute t=1

x= 1+4(1)-1² =1+4-1 = 4

y= 2-t³

Substitute t=1

y= 2-1³ = 2-1 = 1

Given slope, m= -3/2

point slope form of line :

y-y1=m(x-x1)

y-1=-3/2(x-4)

=>2(y-1) = -3(x-4)

=> 2y-2 = -3x+12

=> 2y = -3x+12 + 2

=> 2y = -3x+14

=> y= (-3/2)x + 7

$25 per hour, is their hourly rate of pay.

Division is the process of splitting a number or an amount into equal parts. Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.

here, we have,

Net pay= $1300

Deductions= $200

Hours worked= 60

then,

Total pay=$1300+ $200

               = $1500.

Since her net pay is the money left after deductions, so we add the netpay and deductions to get her total pay.

Therefore, to find her hourly pay, we simply divide the total pay by the hours worked,

so we have 1500/60= $25/hour
