Step-by-step explanation:

A:
Parallel lines never intersect each other because in order for them to be classified as parallel, they must have the same slope, which will never cross over each other at any point; True
B:
A transversal does intersect two or more parallel lines, but crossing two parallel lines at three distinct points is not possible; False
C:
Perpendicular distance between parallel lines is always the same because they have the same slope and therefore are always the same distance away from each other; True

Answer:

The answer is True.

To solve the above equation follow the BODMAS rule

That is,

Brackets of Division Multiplication Addition Subtraction

BODMAS rule states that mathematical expressions with multiple operations need to be solved from left to right in the order of BODMAS.

so,

first, calculate the value in the brackets

(144-4)*(12/4)+3 = (140)*(12/4)+3

=140*(3)+3

According to the rule, a division operation is to be performed but there is no division operation in the equation we skip this step and proceed to the next operation

so, multiply 140*3

=420+3

the next operation is the addition

=423

the next operation according to the rule is subtraction which is not required to be performed in the equation.

therefore,

(144-4)*(12/4)+3 = 423

Answer:

x = 22.5

<ADE = 67.5

Step-by-step explanation:

Triangle = 180 degrees

180 - 1 right angle (90 degrees) = 90 degrees

90 = 4x

x = 22.5

<ADE is corresponding to <ABC, therefore <ADE is also equal to 3x. Since we know x = 22.5 already:

3 x 22.5 = 67.5

so <ADE = 67.5

Answer:

reason being is because -4x is negative while 4x is not.

Answer:

Solving 4x < - 16 gives the answer x < - 4

Solving - 4x < - 16 gives the answer x < 4

In the first inequality, the value of x starts decreasing from the negative side of the number line i. e. from -4 while in the second inequality, the value of x starts decreasing from the positive side of the number line i. e. from 4.

Cohen's conventions for interpreting d, this effect is small. Therefore, the correct answer is a. small.

According to Cohen's conventions for interpreting the effect size (d), the effect described in the study is considered "small." Cohen's conventions provide a general guideline for categorizing the magnitude of an effect size.

In this case, the effect size (d) is calculated to be 0.02. Cohen's conventions typically classify effect sizes as follows:

Small effect: d = 0.2

Medium effect: d = 0.5

Large effect: d = 0.8

Since the effect size of 0.02 is significantly smaller than the threshold for a small effect (0.2), it falls into the "small" category. This means that the difference in the number of words uttered per day between men and women, as reported in the study, is relatively small or negligible in practical terms.

Therefore, the correct answer is a. small.

Both representations convey the same information about the direction and magnitude of the vector AB. The only difference is the reference point from which the displacement is measured.

To find the vector representation of the directed line segment AB, where A is the point (0, 3, 3) and B is the point (5, 3, -2), we subtract the coordinates of A from the coordinates of B.

The vector AB is given by:

AB = B - A

AB = (5, 3, -2) - (0, 3, 3)

AB = (5 - 0, 3 - 3, -2 - 3)

AB = (5, 0, -5)

So, the vector AB is (5, 0, -5).

To draw the line segment AB and its equivalent representation starting at the origin, we start by plotting the point A at (0, 3, 3) and the point B at (5, 3, -2) on a coordinate system.

Using a ruler or straight edge, we draw a line segment connecting the points A and B. This line segment represents the directed line segment AB.

Next, we draw a vector starting from the origin (0, 0, 0) and ending at the point B (5, 3, -2). This vector represents the equivalent representation of AB starting at the origin.

To draw the vector, we measure 5 units in the positive x-direction, 3 units in the positive y-direction, and 2 units in the negative z-direction from the origin. This brings us to the point (5, 3, -2).

We label the vector as AB to indicate its direction and magnitude.

By drawing the line segment AB and the equivalent vector representation starting from the origin, we visually represent the vector AB in two different ways. The line segment shows the displacement from point A to point B, while the vector starting from the origin shows the same displacement but with the reference point at the origin.

The total cost of going to the carnival is $30. The independent variable is the carnival fee and the dependent is the cost of rides.

In any equation, the variables that represent the input and output are referred to as independent and dependent variables, respectively. An independent variable is the one for which we enter the values. The dependent variable is the one that reflects the output value. In mathematics, data techniques, and quantitative sciences, there are dependent and independent variables. Dependent variables are so named because, during an experiment, their values are examined under the presumption or requirement that they do, in fact, depend on other variables' values.

The cost of admission fee at the carnival = $9(independent variable)

Cost of each ride = $1.75

Let the number of rides = x (dependent variable)

The cost of 12 rides = 12 x

= 12( 1.75)
= $21

So, the cost to go to the carnival and 12 rides is

= $9+ $21

= $30

No, the presence of an effect does not necessarily imply that error variance will go away.

The presence of an effect does not necessarily imply that error variance will go away. In fact, error variance is an inherent part of any statistical model and represents the amount of variation in the response variable that is not explained by the predictor variables.

Even if a predictor variable has a significant effect on the response variable, there may still be some unexplained variation in the response that is attributable to error variance.

It is important to take into account and control for error variance in any statistical analysis, as it can affect the precision and accuracy of the estimates of the model parameters and can also influence the interpretation of the results.

One way to control for error variance is to use appropriate statistical methods, such as analysis of variance (ANOVA), regression analysis, or other modeling techniques that take into account the variability in the data.

The interval between doses should be approximately 10.4 hours to maintain a minimum concentration of 30% of the initial concentration in the body.

The interval between doses of a drug depends on its half-life and the desired minimum concentration in the body. The half-life of a drug is the time it takes for half of the initial dose to be eliminated from the body.

To determine the interval between doses, we can use the following formula

t = (t1/2 × ln(Cmin/Cmax)) / ln(2)

Where:

t1/2 is the half-life of the drug

Cmin is the desired minimum concentration in the body (expressed as a fraction of the initial concentration)

Cmax is the initial concentration of the drug

ln represents the natural logarithm function.

Substituting the given values, we get

t = (6.0h × ln(0.3)) / ln(2)

t ≈ 10.4h

b  - width of the rectangle.​

a = b + 5 - length of the rectangle.​

Perimetr:

P = 2* (a + b) = 2*(b + 5 + b) = 2*(2b + 5) = 4b + 10

The area:

S = a*b = (b + 5)*b = b² + 5b

S = 3*P

b² + 5b = 3*(4b + 10)

b² + 5b = 12b + 30

b² - 7b - 30 = 0

D = (-7)² + 4*1*30 = 79 + 120 = 199

Step-by-step explanation:

The 90% confidence interval for the true average of the body temperature is \($(36.07,37.91)$\). The upper limit of the confidence interval rounded to two decimal places is 37.91.

To find the 90% confidence interval for the true average of the body temperature, we will use the following formula:

\($$\bar{x}-z_{\alpha/2}\frac{\sigma}{\sqrt{n}},\bar{x}+z_{\alpha/2}\frac{\sigma}{\sqrt{n}}$$\)

where

\($\bar{x}$\) is the sample mean,

\($\sigma$\) is the standard deviation of the sample,

\($n$\) is the sample size and

\($z_{\alpha/2}$\) is the critical value for the given level of confidence.

Let us plug in the given values to the above formula.

\($$\bar{x}=36.99°C$$$$\sigma=1.13°C$$$$n=56$$$$\alpha =1-0.9=0.1$$$$z_{\alpha/2}=z_{0.05}=1.645$$\)

Substituting the values in the formula, we get;

\($$\begin{aligned}\bar{x}-z_{\alpha/2}\frac{\sigma}{\sqrt{n}} &\leq \mu \leq \bar{x}+z_{\alpha/2}\frac{\sigma}{\sqrt{n}}\\36.99-1.645\cdot \frac{1.13}{\sqrt{56}}&\leq \mu \leq 36.99+1.645\cdot \frac{1.13}{\sqrt{56}}\\36.07&\leq \mu \leq 37.91\end{aligned}$$\)

Therefore, the 90% confidence interval for the true average of the body temperature is \($(36.07,37.91)$\).

The upper limit of the confidence interval rounded to two decimal places is 37.91.
