Answer:

  50%

Step-by-step explanation:

You want the probability of rolling a divisor of 45 on a 6-sided die.

The probability is the ratio of outcomes of interest to the total number of possible outcomes, assuming they are equally likely.

The numbers on a die that are divisors of 45 are 1, 3, 5, which are 3 of the 6 possible outcomes.

  P(divisor of 45) = 3/6 = 1/2 = 0.50 = 50%

The probability of rolling a divisor of 45 is 50%.

As per normalization, the session table uses the third normal form

Normalization is an important step in designing a database, as it helps to eliminate issues such as data integrity and redundancy. This is achieved through a series of steps, known as normalization.

The Sports Physical Therapy Center database has a table named Session that keeps track of all therapy appointments at the center. The table contains various pieces of information such as the session number, date, patient number, length of session, therapist ID, therapist's last and first name, and the therapy code.

The Session table is used to check if there are any design issues and to apply the necessary normalization steps to fix these issues and ensure data is stored in an organized manner.

The total cost of the dinner is given by the equation A = $ 161.19

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total cost of the dinner be represented as A

Now , the equation will be

The cost of the dinner without tax and tip = $ 128.95

The sales tax percentage = 7.5 %

So , the sales tax amount = ( 7.5 % ) x cost of the dinner without tax and tip

Substituting the values in the equation , we get

The sales tax amount = ( 7.5/100 ) x 128.95

The sales tax amount = $ 9.0265

Now , the percentage of tip = 18 %

So , the tip amount = ( 18 % ) x 128.95

The tip amount = $ 23.211

And , the total cost of the dinner A = cost of the dinner without tax and tip + sales tax amount + tip amount

On simplifying the equation , we get

The total cost of the dinner A = $ 128.95 + $ 9.0265 + $ 23.211

The total cost of the dinner A = $ 161.1875

Hence , the total amount of dinner is $ 161.19

Answer: Let's call the number of hours worked h.

The cost of hiring Carmony is $255 + $85h.

The cost of hiring Holliday is $115h.

We want to find the number of hours h such that $255 + $85h is less than $115h.

We can write this as:

$255 + $85h < $115h

Subtracting $115h from both sides:

$255 < $115h - $85h

Combining like terms:

$255 < $30h

Dividing both sides by $30:

8.5 < h

So, it is cheaper to hire Carmony for more than 8.5 hours. For 8.5 hours or less, it is cheaper to hire Holliday.

A transformation of a function is a process that changes the position or shape of the function on a coordinate plane. There are several types of transformations, including:

Translation: A translation moves the graph of a function horizontally or vertically, but does not change its shape. This can be accomplished by adding or subtracting a constant to the input or output of a function.

Scaling: A scaling changes the size of a function's graph, but not its shape. This can be accomplished by multiplying the input or output of a function by a constant.

Reflection: A reflection flips the graph of a function over a line. This can be accomplished by negating either the input or the output of a function.

Stretching or Compression: A stretching or compression changes the height or width of a function's graph, but not its shape. This can be accomplished by multiplying the output of a function by a constant greater than 1 for stretching, or by a constant between 0 and 1 for compression.

These transformations can be used to shift, scale, reflect or distort the graph of a function, allowing for greater understanding and analysis of its properties.

The hole of f(x) is x = -3.

Option A is the correct answer.

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

f(x) = (x + 3) / (x - 4)(x + 3)

Now,

We see that there is a common factor both in the numerator and the denominator.

This means,

There is a hole in f(x).

Answer: x = -3

Step-by-step explanation:

correct on edge :)

The possible values of the number x are any real number that is less than or equal to 103.2. This can be written as: x <= 103.2

Let's call the number "x".

The sum of 4.5 and one-third of x can be written as:

4.5 + (1/3)x

The inequality to represent the statement "the sum is equal to at most 38.9" would be:

4.5 + (1/3)x <= 38.9

To solve for x, we can isolate x by subtracting 4.5 from both sides:

(1/3)x <= 34.4

And finally, multiplying both sides by 3:

x <= 103.2

So, all the possible values of the number x are any real number that is less than or equal to 103.2. This can be written as:

0.00426 is the probability of being dealt six clubs and three cards with one card .

Describe probability using an example?

A number between 0 and 1 is the probability of an event, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

                                 The likelihood of an event occurring increases as its probability increases. The flip of a fair (impartial) coin serves as a straightforward illustration.

We will get 9 cards out of 52 cards

Probability of getting 6 clubs is

total we have 13 clubs

no of chances = 13C6

chances of getting 3 cards from 3 other suits

= 39C3

Now, the total probability

Function f(x) is translated to the right 5 units.

resizing an object is accomplished through a change called dilation. The objects can be enlarged or shrunk via dilation. A shape identical to the source image is created by this transformation. The size of the form does, however, differ. A dilatation ought to either extend or contract the original form. The scale factor is a phrase used to describe this transition.

The scale factor is defined as the difference in size between the new and old images. An established location in the plane is the center of dilatation. The dilation transformation is determined by the scale factor and the center of dilation.

Any probability statement involving a normal random variable can be converted to an equivalent statement involving a standard normal random variable through the process of standardization.

Standardization is converting a normal random variable, X, to a standard normal random variable, Z, by subtracting its mean, μ, and dividing by its standard deviation, σ. The formula for standardization is given:

Z = (X - μ) / σ

Once a normal random variable has been standardized, it is easier to find probabilities because the standard normal distribution is well-known and widely used in statistical analysis. For example, if X is normally distributed with mean μ and standard deviation σ, the probability of X being between two values a and b can be found using the cumulative distribution function (CDF) of the standard normal distribution.

It takes Ermias and Manuel 3.43 hours to paint the room if they are working together. To find the time it takes for Ermias and Manuel to paint the room together, we can use the formula: 1/rate = time.

The rate is the combined painting rate of both workers, which is equal to the sum of their individual painting rates.

Let's call the time it takes for Ermias and Manuel to paint the room together "T". The combined painting rate of both workers is then 1/T.

The individual painting rates of Ermias and Manuel are 1/8 hours per room and 1/6 hours per room, respectively. Therefore, their combined painting rate is 1/8 + 1/6 = 6/48 + 8/48 = 14/48 hours per room.

Now we can use the formula 1/rate = time to find T:

1/ (14/48) = T

48/14 = T

T = 3.43 hours

So it takes Ermias and Manuel 3.43 hours to paint the room if they are working together.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Female colorblindness proportion = 1%

Male colorblindness proportion = 8%

Female sample size = 40

Male sample size = 20

Hence, We get;

Let us check if the condition np ≥ 10 is satisfied or not,

⇒ np

⇒ 40 × 0.01

⇒ 0.4 < 10

Since, the condition np ≥ 10 is not satisfied the binomial random variable cannot be well approximated by a normal random variable. A larger sample size would be required to satisfy the condition np ≥ 10.

Hence, The mean is,

μ = np

μ = 40*0.01

μ = 0.40

And, The standard deviation is,

σ = √p(1 - p)/n

σ = √0.01(1 - 0.01)/40

σ = 0.015

Thus, We get;

Mean = μ = 0.40

Standard deviation = σ = 0.015
