Explanatory variables in a regression model are typically considered to be random when they are subject to variability or uncertainty. There are several reasons why explanatory variables may be treated as random:

Measurement error: Explanatory variables may be measured with some degree of error or imprecision. This measurement error introduces randomness into the values of the variables. Accounting for this randomness is important to obtain unbiased and accurate estimates of the regression coefficients.

Sampling variability: In many cases, the data used to estimate the regression model are obtained through sampling. The values of the explanatory variables in the sample may differ from the true population values due to random sampling variability. Treating the explanatory variables as random helps capture this uncertainty and provides more robust inference.

Random assignment in experiments: In experimental studies, researchers often manipulate or assign values to the explanatory variables randomly. This random assignment ensures that the variables are not influenced by any underlying factors or confounders. Treating the explanatory variables as random reflects the randomization process used in the experiment.

By considering the explanatory variables as random, we acknowledge and account for the inherent variability and uncertainty associated with them. This allows for a more comprehensive and accurate modeling of the relationships between the explanatory variables and the response variable in regression analysis.

The distribution of W = Σ W_i/n is a normal distribution with mean μ and variance σ²/n, where Wi's are independent normal random variables with a common variance σ².

When you sum up independent normal random variables (W_i's), the resulting distribution (W) will also be normal.

The mean (μ) of the resulting distribution is the sum of the means of the individual Wi's divided by n, and the variance is the sum of the variances of the individual Wi's divided by n². Since Wi's have a common variance σ², the variance of W is σ²/n. Therefore, W follows a normal distribution with mean μ and variance σ²/n.

When radioing the hospital to give a report on a patient, it is important to use code words to protect the patient's identity, remain objective and impartial, and provide as much detail as possible.

It is not necessary to speak quickly, as clear and accurate communication is more important than speed. Providing detailed information about the patient's condition, including vital signs and any treatment administered, will help the hospital staff prepare for the patient's arrival and provide appropriate care.

A representation that could represent function w (nonlinear function) is: D. table D.

In Mathematics, a linear function can be defined as a type of function whose equation is graphically represented by a straight line on the cartesian coordinate.

This ultimately implies that, a linear function has the same slope and it is typically used for uniquely mapping an input variable to an output variable, which both increases simultaneously.

Therefore, table D represents a non-linear function because the slope is not constant and the common difference is not constant between successive data points.

The equation in slope-intercept form that represents the e line on Isabella's map is y = 8x - 67.  

To write the equation of the e line in slope-intercept form, we need to find the slope of the line since we already have one point on the line. Since the a line and e line are parallel, they have the same slope. Therefore, the slope of the e line is also 8.

Next, we can use the point-slope form of the equation of a line to find the equation of the e line. The point-slope form is:

y - y1 = m(x - x1)

where m is the slope and (x1, y1) is a point on the line.

We know that the e line passes through the point (9, 5) and has a slope of 8, so we can plug these values into the point-slope form:

y - 5 = 8(x - 9)

Now, we can simplify this equation to slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept:

y - 5 = 8x - 72

y = 8x - 67

Therefore, the equation in slope-intercept form that represents the e line on Isabella's map is y = 8x - 67.

Step-by-step explanation:

The amount credited from the partial payment made during the discount period is $1,470. The balance on the invoice after the partial payment was made is $1,530.

The payment terms "4/10n/45" indicate that a 4% discount is applicable if the payment is made within 10 days, and the full amount is due within 45 days. Marcus made a partial payment of $1,500 during the discount period.

To calculate the amount credited, we first determine the discount amount by multiplying the invoice amount ($3,000) by the discount percentage (4%). This gives us a discount of $120. Since Marcus made a partial payment of $1,500, we subtract the discount amount from the partial payment to find the credited amount. Therefore, $1,500 - $120 = $1,380. Rounded to the nearest cent, the amount credited is $1,380.

To calculate the balance on the invoice after the partial payment was made, we subtract the credited amount from the remaining balance. The remaining balance is the invoice amount ($3,000) minus the partial payment ($1,500), which equals $1,500. Subtracting the credited amount of $1,380 from this balance, we get $1,500 - $1,380 = $120. Rounded to the nearest cent, the balance on the invoice after the partial payment is $120.

In summary, the amount credited from the partial payment made during the discount period is $1,380, and the balance on the invoice after the partial payment was made is $120.

Length of parking lot = 20 feets

Speed of tortoise which starts at the edge = 6 feets per minute

Speed of tortoise which starts 4 feets from the edge = 2 feets per minute

Equation to represent when they will be in the same spot.

Distance = speed * time

Distance of Tortoise at edge = 6ft/min * t = 6t - - (1)

Distance of the other tortoise = (4 + 2t) - - - (2)

Equating both (1) and (2)

6t = 4 + 2t

6t - 2t = 4

4t = 4

t = 4/4

t = 1

Step-by-step explanation:

The 95% confidence interval for the mean value of y is (107.978, 170.584) when x1 = 36 and x2 = 12, and the 95% prediction interval for an individual observation of y is (42.734, 235.827) when x1 = 36 and x2 = 12. These intervals give us an idea of the range of values we can expect for y, given certain values of x1 and x2, and provide a measure of uncertainty around our estimates.

(a) To find the 95% confidence interval for the mean value of y when x1 = 36 and x2 = 12, we use the estimated regression equation ỹ = -18.4 + 2.01x1 + 4.74x2 and plug in the values for x1 and x2 to obtain an estimate of the mean value of y.

Then, we use the standard error of the estimate to construct the confidence interval. The 95% confidence interval is (107.978, 170.584).

(b) To find the 95% prediction interval for y when x1 = 36 and x2 = 12, we again use the estimated regression equation to obtain an estimate of the mean value of y.

However, we also need to account for the variability in individual observations around the mean.

Therefore, we use the residual standard error to construct the prediction interval. The 95% prediction interval is (42.734, 235.827).

Answer:

c

Step-by-step explanation:

when the acceleration of gravity is 9.81 m/s 2 and the density of sea water is 1025 kg/m3. Then the ocean's depth is 20.15 meters.

Given that,

Pressure \(P= 3 P atm\)

atmospheric pressure \(Patm = 1.013\) × \(10{5} Pa\)

Gravitational acceleration = 9.81 m/s2

The density of sea water is 1025 kg/m3.

We need to figure out how deep the ocean is.

 \(h = P -Po \\ pg\)

Using the Depth Formula

\(h = 3 x 1.013 x 10 *5 -1.013 x10*5/ 1025 x9.81\\ \\ \\ h =20.15m\)

In this case, =Atmospheric pressure

P stands for total pressure.

g = gravitational acceleration

\(p\) = seawater density

Fill in the value inside the formula

Hence, The depth of the ocean is 20.15 meters.
