Three people: Alan, Betty, Carol

Alan has 9 shares.

Betty has 10 shares.

Carol has 11 shares.

Therefore, there are a total of 9 + 10 + 11 = 30 shares.

Since the profit is $67,500, let's divide this one by the total number of shares.

The profit per share is $2,250.

Since Alan has 9 shares, let's multiply $2,250 to 9.

Therefore, Alan's share must be $20,250.

Let's do the same with Betty and Carol.

To summarize, Alan will receive $20,250, Betty will receive $22,500, and Carol will receive $24,750 from the proft

Step-by-step explanation:

A line of symmetry is a line you could place on a shape (usually a square, rectangle, triangle, etc, but here the "shape" is the word checkbook) which, if you folded the shape on the line, the two halves of the shape would exactly match each other.

"checkbook" does NOT have any lines of symmetry. BUT,

CHECKBOOK

does have a line of symmetry, horizontally, right thru the middle.

Vertical angles are : 1 and 6

supplementary angles : 1 and 2

linear pair : angle 4 and 8

adjacent angles: 21 and 22

A supplementary angle is an angle that, when added to another angle, results in a total angle measure of 180 degrees. In other words, if two angles are supplementary, the sum of their angle measures will be equal to 180 degrees.

For example, if angle A measures 100 degrees, its supplementary angle B would measure 80 degrees, since 100 + 80 = 180. Conversely, if angle B measures 120 degrees, its supplementary angle A would measure 60 degrees, since 120 + 60 = 180.

Answer: The perimeter of the triangle is 69 cm.

Step-by-step explanation:

Let us consider the side of the triangle be 3x ,4x and 5x.

According to the question,

The longest side of the triangle be 30 cm.

. 5x=30cm

Hill's Criteria of Strength is the only criteria that must be met 100% for a causal relationship to be possible.

The Criteria of strength is Hill's first test for causation. He stated that the likelihood of an association being causative increases with the size of the connection between exposure and disease. Hill used Percival Pott's investigation into the prevalence of scrotal cancer in chimney sweeps to highlight this issue. Since the correlation between that occupation and sickness was so strong (almost 200 times more than in other jobs), it was concluded that chimney soot was probably a contributing factor. On the other hand, Hill argued that minor connections are less indicative of causation since they are more likely to be explained by other underlying factors (such as bias or confounding).

To evaluate possibly causative associations, it is essential to define what is meant by a "strong" correlation. Scientists may now distinguish between strong and weak associations using more mathematically sound criteria than Hill had in mind because of developments in statistical theory and computing capacity. Strength is no longer just understood as an association's magnitude. Furthermore, multi-factorial disorders and the existence of determinant risk variables that are tiny in magnitude but statistically significant have received more attention from researchers. The recognized standard for determining the strength of an observed correlation and, hence, its potential causation, is statistical significance today rather than the magnitude of the association.

Using the relation between velocity, distance and time, it is found that:

a. The equation used to find the distance of the flowerbed from the​ hive is: d = 540 feet per minute x 1.6 minutes.

b. The distance of the flower bed from the hive is: 864 feet.

Velocity is given by the distance divided by the time, as follows:

v = d/t

In the context of this problem, we have that:

The times are as follows:

The sum of this times is of 22 - 18 = 4 minutes, hence:

[tex]t_1 + t_2 = 4[/tex]

During the first step, that is, from hive to flowerbed, the velocity is 1.5 times greater than during the second step, thus the second time is 1.5 times the first time, that is:

[tex]t_2 = 1.5t_1[/tex]

Then the first time is calculated as follows:

[tex]1.5t_1 + t_1 = 4[/tex]

[tex]2.5t_1 = 4[/tex]

[tex]t_1 = \frac{4}{2.5}[/tex]

[tex]t_1 = 1.6[/tex]

The velocity during this time was of 9 feet per second = 540 feet per minute, for 1.6 minutes, hence the equation is:

d = v x t

d = 540 feet per minute x 1.6 minutes.

d = 864 feet.

The Central Limit Theorem states that over a large number of samples, the sampling average of the sample means would be closer to the population mean.

The Central Limit Theorem states that for a random variable X, with mean given by [tex]\mu[/tex] and standard deviation given by [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

This means that over a large number of trials, i.e., of samples from the population, the mean of the sample means will be close to the population mean, with a small standard error, as the standard error is inversely proportional to the square root of the sample size.

Temperature simply means the degree of hotness and coldness in a body.

In this case, they find that the surface temperature at one location is 45 ° Celsius. They also find that the temperature decreases by 7 ° Celsius for each kilometer you go up from the surface.

Let T = the temperature (in Celsius).

We are given the following absolute value equation

Let us solve the problem then we will compare it with the given solution.

Now we will solve for the positive and negative sign separately

Comparing it with the given solution, there is an error on the left-hand side step 2. (the sign of 38 should be positive but in the figure, it is shown negative)

Now let us substitute the obtained x values into the original absolute value equation and check if they satisfy the equation.

For x = -4:

Hence, x = -4 is a valid solution.

For x = -38:

Hence, x = -38 is not a valid solution.

The above is an example of an extraneous solution.

An extraneous solution is a solution that we get during the process of solving an equation but it is not really the solution meaning that it does not satisfy the equation!

Therefore, x = -4 is the only solution to the given equation.

The building is 5.88 units tall.

It is given that the ball is dropped from a tall building.

The formula in the box relates the distance in meters "d" fallen to the time in seconds "t".

The formula is given below :

d = 4.9*t

The ball falls for a total of 1.2 seconds before hitting the ground.

The ball will travel a distance in the time interval from when the ball is dropped until it hits the ground.

The time for which the ball travels the distance is 1.2 seconds.

The distance travelled by the ball is :

d = 4.9*t

d = 4.9*1.2

d = 5.88

Hence, the ball travels a distance of 5.88 after it is dropped from the top of the building and before hitting the ground.

The height of the building is equal to the distance calculated.

The height of the building is 5.88.

The height, h of the parallelogram is 4 feet.

A parallelogram is a quadrilateral with opposites sides equal to each other. Opposite sides of a parallelogram are also parallel to each other.

Opposite angles of a parallelogram are congruent. The consecutive or adjacent angles of a parallelogram is supplementary.

Therefore, the height of the parallelogram can be found as follows:

The sum of angles in a parallelogram is 360 degrees.

Hence,

sin ∅ = opposite / hypotenuse

where

sin ∅ = 3 / 6

sin ∅ = 1 / 2

∅ = sin⁻¹ 0.5

∅ = 30

Therefore,

30 + 30 + 2x = 360

where

60 + 2x = 360

2x = 360 - 60

2x = 300

x = 300 / 2

x = 150

Let's find the height of the parallelogram using trigonometric ratios,
