Answer:

259.5

Step-by-step explanation:

8.1*12=97.2
Area of trapiezium = 1/2(b+a)h
(2.8+8.1)=10.9
10.9*3/2=16.35
16.35*2=32.7
2.8*12=33.6
33.6+32.7+97.2=163.5
4*12*2=96
163.5+96=259.5

We need to solve the algebraic expression:

-2(x+8) + 6(5 + (_)x) = 10x + 14

Expanding the operations and grouping similar terms:

-2x -16 + 30 + 6(_)x = 10x + 14

-2x + 6(_)x -16 + 30 = 10x + 14

To solve this, we need to equaling each similar term at both sides of the equation:

-2x + 6(_)x = 10x [1]

-16 + 30 = 14 [2]

14 = 14

We need to solve the following equation:

-2x + 6(_)x = 10x

We can rewrite the previous equation as follows:

-2 + 6x = 10

6x = 10 + 2

x = (12/6)

x = 2

Checking the previous result, we have:

-2 + 6(2) = 10

-2 + 12 = 10

10 = 10

Then the value for the blank in the question is 2.

Checking equation [1]:

-2x + 6(2)x = 10x

-2x + 12x = 10x

10x = 10x

Therefore, we have then:

10x + 14 = 10x + 14

Step-by-step explanation:

The statement "the standard deviation of a single data set and the standard error of a sampling distribution is typically the same value" is FALSE.

The standard deviation (SD) is a statistical measurement that indicates how much data is dispersed. The SD calculation considers all data points, both above and below the mean, rather than simply the mean. SD can be calculated for a single data set, as well as the SD of the mean for a population, the SD of the mean for a sample, and the SD of the mean for a sampling distribution.

The standard error (SE) is a statistical measurement that shows how precise the mean of a population or sample is to the true value. The SE measures how the sample mean deviates from the true population mean. It's important to keep in mind that SE is the standard deviation of the mean for a population or sample, not the standard deviation of the raw data.The statement "the standard deviation of a single data set and the standard error of a sampling distribution is typically the same value" is false.

The reason being is that the standard deviation of a single data set and the standard error of a sampling distribution are not the same value. The standard deviation of a single data set measures the variability of the data set, while the standard error of a sampling distribution measures the precision of the sample mean as an estimator of the population mean.

Answer:

x = 8 and y = 5

Step-by-step explanation:

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

x + 2y = 18

x = 18 - 2y --(2)

sub (2) into (1):

2(18 - 2y) - 3y = 1

36 - 4y - 3y = 1

-7y = 1 -36

7y = 35

y = 5

x = 18 - 2(5) = 8

Step-by-step explanation:

in order to be able to decide each case we need the slopes of all involved lines.

and that means we need to bring all of the equating into a "y = ..." form, because then the slope is always the factor of x.

parallel lines have the same slope.

the slopes of perpendicular lines (intercept at a right angle) have the y/x ratio turned upside-down and a flipped sign : -x/y.

"neither" is everything else.

our reference line

x + 2y = 6

2y = -x + 6

y = -1/2 x + 3

so, the reference slope is -1/2.

y = -1/2 x - 5 is parallel (same slope).

-2x + y = -4

y = 2x - 4 perpendicular (2/1 vs. -1/2)

-x + 2y = 2

2y = x + 2

y = 1/2 x + 1 neither

x + 2y = -2 parallel (as the structure except for the constant part is the same as our reference line).

2y = -x - 2

y = -1/2 x - 1

Step-by-step explanation:

Mean and standard deviation is more affected by extreme observations.

Mean is the summation of all the values divided by the total number of values. It is also called as average. Median is the middle value.Standard deviation is the dispersion of a dataset relative to its mean. In case of extreme items arithmetic mean is affected very much. For this reason, it no longer remains representative of the distribution. As standard deviation is the positive square root of the arithmetic mean of the square of deviations of all given values, it is also affected by extreme items. As median is a partition value, it is not affected by extreme items.

The number on round off to each place will be 45,621.

The decimal number is rounded to any place by the following concept -

We look at the number to the right of concerned digit. If that number is more than five or exactly five, then we add 1 to our number. However, if it is less than five, then the number remains same.

For instance, if we round 45.621 to nearest tenth, we will get 45.6. This is because on right to it, the number 2 is less than 5. Now, in the mentioned digit which is 45,621, we see there is no decimal and number after that. So, as the digits are 0 which is less than 5, the number will remain as it is.

The exact length of the curve. y = 3 + 4x^3/2, 0 ≤ x ≤ 1 is L = ∫√(9+108x-144x^(5/2)) / √(9-16x^3) dx, from 0 to 1.

To find the length of the curve, we need to use the arc length formula:

L = ∫√(1+(dy/dx)^2) dx, where y = 3 + 4x^(3/2) and 0 ≤ x ≤ 1.

First, we need to find dy/dx:

dy/dx = (12x^(1/2))/2√(3 + 4x^(3/2))

dy/dx = 6x^(1/2)/√(3 + 4x^(3/2))

Now, we can substitute this into the arc length formula:

L = ∫√(1+(6x^(1/2)/√(3 + 4x^(3/2)))^2) dx, from 0 to 1.

Simplifying the inside of the square root, we get:

L = ∫√(1+(36x)/(3 + 4x^(3/2))) dx, from 0 to 1.

We can simplify this further by multiplying the numerator and denominator of the fraction by (3 - 4x^(3/2)):

L = ∫√(1+36x(3-4x^(3/2))/(9-16x^3)) dx, from 0 to 1.

Expanding the numerator, we get:

L = ∫√((9+108x-144x^(5/2))/(9-16x^3)) dx, from 0 to 1.

Simplifying the expression under the square root, we get:

L = ∫√(9+108x-144x^(5/2)) / √(9-16x^3) dx, from 0 to 1.

We can evaluate this integral using numerical methods, such as Simpson's rule or the trapezoidal rule, to get an approximation of the length of the curve. The exact length of the curve cannot be expressed in a finite number of terms, but it can be approximated to any desired degree of accuracy using numerical methods.

The angular acceleration the eyelid undergoes while closing is approximately 13.93 rad/s².

To find the angular acceleration (α) of the eyelid while closing, we can use the equations of rotational motion. The given data is:

Angular displacement (θ) = 13.4 degrees

Time interval for closure (Δt) = 55 ms = 0.055 s

We can use the following equation to relate angular displacement, angular acceleration, and time:

θ = 0.5 * α * t²

Plugging in the values:

13.4 degrees = 0.5 * α * (0.055 s)²

Let's convert the angular displacement from degrees to radians:

θ = 13.4 degrees * (π/180) radians/degree

θ ≈ 0.2332 radians

Now, we can rearrange the equation to solve for α:

α = (2θ) / (t²)

α = (2 * 0.2332 radians) / (0.055 s)²

Calculating the value:

α ≈ 13.93 radians/s²

Therefore, the angular acceleration the eyelid undergoes while closing is approximately 13.93 rad/s².

The best linear prediction rule minimizes the mean squared error when predicting from the mean. This rule aims to minimize the error between the predicted values and the actual values, resulting in more accurate predictions.

When it comes to linear prediction, the goal is to find a rule that can accurately estimate or predict an outcome based on given input variables. The best linear prediction rule is determined by minimizing the error between the predicted values and the actual values. One commonly used measure of prediction accuracy is the mean squared error (MSE).

To understand why the best linear prediction rule minimizes the MSE, let's break it down. The MSE is calculated by taking the average of the squared differences between the predicted values and the actual values. By minimizing the MSE, we are essentially minimizing the overall prediction error.

When predicting from the mean, the best linear prediction rule minimizes the MSE by finding a linear relationship between the input variables and the outcome. This rule is derived by analyzing the data and finding the coefficients that minimize the squared differences between the predicted values and the mean.

The error when predicting using the best linear prediction rule is minimized because this rule optimally captures the underlying patterns and relationships in the data. It takes into account the covariance between the input variables and the outcome, allowing for more accurate predictions.

Finally, the best linear prediction rule minimizes the mean squared error when predicting from the mean. By minimizing the error, this rule provides a more accurate estimation of the outcome variable based on the given input variables. It takes into account the relationships and patterns in the data, resulting in improved prediction accuracy.
