The following is true about the study: e. It has one factor (medication) blocked by age.

In statistics, when a factor (independent variable) is blocked by another factor, it means that the effect of the first factor is controlled or eliminated by the second factor.

In this case, the factor that is blocked is the medication, which means that the effect of medication on the outcome variable is controlled by age.

Blocking a factor is often done in experimental design to remove the effects of extraneous variables or to control the influence of certain factors on the outcome variable.

In this case, age is considered a blocking variable because it is not of interest in the study, but it may have an effect on the outcome variable. By blocking the effect of medication by age, the study can better isolate the effect of medication on the outcome variable.

In summary, the statement e. "It has one factor (medication) blocked by age" is correct which means that the study controlled for the effect of age on the outcome variable by blocking the effect of medication by age.

Answer:

27 students

Step-by-step explanation:

\(\frac{78}{100} =\frac{x}{35} \\\)

cross multiply and you get 27

All this question is trying to ask is to find 78% percent of the total number of student in the class.

So first convert 78 to decimal by dividing it by 100: \(\frac{78}{100} = 0.78\)

Next multiply that with the total number of students which is 35.

So, \(0.78 * 35 = 27.3\)

Now I don't think there can be a decimal here. The question must be wrong or the percentage might be incorrect. But, just for sake, we'll round it up so the final answer would be: \(27\)

The proportion would be: \(273:10\)

The statement that is true abut the slopes of perpendicular lines is that: D. One of the slopes is negative and the other is positive.

If two lines are perpendicular, it means that their slope (which is the change in y over x or rise/run along the line) will be negative reciprocal to each other.

For example, if the slope of one line is 2, the slope of any line that is perpendicular to the line must be negative reciprocal to 2, which is -1/2.

If we multiply their slopes together, we must have -1. I.e. 2 * -1/2 = -1. Therefore, if one is negative the other would be positive.

The correct answer is: D. One of the slopes is negative and the other is positive.

Unconscious processing is a complex cognitive phenomenon that involves a wide range of mental activities that occur outside of our conscious awareness. It is not simply a group of answer choices or a set of predetermined responses that are guided by habit or well-established routines.

Rather, unconscious processing is a highly nuanced and multifaceted process that is guided by a variety of different factors, including our emotions, our past experiences, our cultural background, and our personal beliefs and values.

At the same time, it is important to note that unconscious processing is not entirely independent of our executive functions or our conscious awareness. While it may be composed of relatively specialized parts, such as our automatic reflexes and basic sensory processing systems, these parts are still intricately connected to the higher-level cognitive processes that govern our decision-making, problem-solving, and goal-oriented behavior.

In short, unconscious processing is a complex and dynamic process that involves a broad range of cognitive and emotional factors, and is intimately intertwined with our conscious awareness and executive functions.

Answer:

\(7y=-5x-11\)

Step-by-step explanation:

Since it says the lines are parallel both of their gradients will be same.

so gradient of line 1 = \(y=\frac{14-5x}{7}\) = \(y=\frac{14}{7}-\frac{5x}{7}\)= \(-\frac{5}{7}\)

so equation of line 2 = \(y-y_{1}=m(x-x_{1} )\)

                                   = \(y-(-3)_{}=\frac{-5}{7} (x-(-2)_{} )\)

                                   = \(y +3=-\frac{5}{7}x+\frac{10}{7}\)

                                   = \(y =-\frac{5x+10}{7}-3\)

                                   = \(7y=-5x-11\)

Step-by-step explanation:

basically a line equation typically looks like

y = ax + b

with a being the slope, and b bent the y-intercept (y value when x = 0).

5x + 7y = 14

7y = -5x + 14

y = -5/7 x + 14/7 = -5/7 x + 2

so, wie know the slope of the original line : -5/7 .

any line parallel to it must have the same slope.

our desired line looks like

y = -5/7 x + b

to get b we use the provided point (-2, -3).

-3 = -5/7 × -2 + b = 10/7 + b

-21/7 = 10/7 + b

-31/7 = b

and the full equation is

y = -5/7 x - 31/7

7y = -5x - 31

5x + 7y = -31

Answer:

.

Step-by-step explanation:

.

There would be no asterisks plotted, indicating no outliers, as none of the observations (20, 24, and 28) fall below the lower fence or above the upper fence. The correct answer is b.

Based on the information, none of the observations 20, 24, and 28 can be classified as outliers since they are not below the lower fence or above the upper fence.

In a box plot, outliers are typically defined as observations that fall below the lower fence (Q1 - 1.5 * IQR) or above the upper fence (Q3 + 1.5 * IQR), where IQR is the interquartile range (Q3 - Q1).

Since the given data set does not contain any observations below the lower fence or above the upper fence, there would be no asterisks plotted to indicate outliers (option b is true). The three smallest observations (20, 24, and 28) are within the acceptable range and are part of the data set's distribution.

Therefore, the correct answer is b. There would be no asterisks plotted, indicating no outliers.

To calculate ∗f∗g by directly evaluating the integral in the definition of ∗f∗g, we need to find the convolution of the functions f(t) = et and g(t) = −4e−4t over the interval 0 ≤ t < ∞.

The convolution of two functions f(t) and g(t) is defined as:

(f * g)(t) = ∫₀ᴛ f(τ) g(t - τ) dτ

To calculate the convolution of f(t) and g(t), we need to substitute the given functions into the definition:

(f * g)(t) = ∫₀\(ᴛ e^τ (-4e^(−4(t-τ))) dτ\)

= \(-4e^(-4t)\)∫₀ᴛ\(e^(5τ)\) dτ

Using integration by substitution, we can simplify this integral to:

(f * g)(t) = -4e^(-4t) [(e^(5t) - 1) / 5]

Therefore, ∗f∗g = (f * g)(t) = \(-4/5 + (4/5)e^(t-4t) = -4/5 + (4/5)e^(-3t)\))

Thus, we have calculated the convolution of f(t) = et and g(t) = −4e−4t by directly evaluating the integral in the definition of ∗f∗g.

The utilization of the teller is approximately 53.33%.

To calculate the utilization of the teller, we need to compare the arrival rate and the service rate. The utilization represents the fraction of time the server (teller) is busy serving customers.

The arrival rate is given as 8 customers per hour, which means that, on average, 8 customers arrive at the teller's window in one hour. This follows a Poisson distribution.

The service rate is given as 15 customers per hour, indicating that, on average, the teller is able to serve 15 customers in one hour. The service times follow an exponential distribution.

Utilization is calculated as the ratio of the arrival rate to the service rate. In other words:

Utilization = Arrival rate / Service rate

Substituting the given values:

Utilization = 8 / 15 ≈ 0.5333

To express this as a percentage, we multiply the result by 100:

Utilization = 0.5333 * 100 ≈ 53.33%

Therefore, the utilization of the teller in this scenario is approximately 53.33%. This means that, on average, the teller is occupied serving customers about 53.33% of the time, and the remaining time is idle or available for serving new customers.

It is defined as two-dimensional geometry in which the angle between the adjacent sides is 90 degrees. It is a type of quadrilateral.

It is defined as the area occupied by the rectangle in two-dimensional planner geometry.

The area of a rectangle can be calculated using the following formula:

Rectangle area = length x width

It is given that:

A sidewalk that is 2 feet wide surrounds a rectangle that is 4 feet by 6 feet.

As we know,

The area of the rectangle = length x width

First, the area of the rectangle = 4x6 = 24ft²

The polar equation for this curve is: theta = pi/3 (or any angle that satisfies tan(theta) = sqrt(3))

To find the polar equation for the curve represented by the given Cartesian equations, we can use the conversion formulas between Cartesian and polar coordinates.

\(x^2 + y^2 = 25:\)

In polar coordinates, the conversion formulas are:

x = r cos(theta)

y = r sin(theta)

Substituting these values into the equation \(x^2 + y^2 = 25:\)

\((r cos(theta))^2 + (r sin(theta))^2 = 25\)

\(r^2 (cos^2(theta) + sin^2(theta)) = 25\)

\(r^2 = 25\)

The polar equation for this curve is simply:

r = 5

\(x^2 + y^2 = -8y:\)

x = r cos(theta)

y = r sin(theta)

Substituting these values into the equation \(x^2 + y^2 = -8y:\)

\((r cos(theta))^2 + (r sin(theta))^2 = -8(r sin(theta))\)

\(r^2 (cos^2(theta) + sin^2(theta)) = -8r sin(theta)\)
