The solution for the given equation √2x - 7 = 1 is  extraneous .

Mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.

Solve for x , √2x - 7 = 1

1x − 2+1x + 2=4(x − 2)(x + 2) .

1x − 2+1x + 2=4(x − 2)(x + 2)

(x − 2)(x + 2)(x − 2)+(x − 2)(x + 2)(x + 2)=4(x − 2)(x + 2)(x − 2)(x + 2)

(x−2)+(x+2)=4

2x=4

x=2

However, since division by zero is prohibited, the number 2 is not included in the range of the original equation because it would reduce one of the fractions' denominators to zero.

As a result, it can't be one of the roots of the initial equation.

2 is therefore an erroneous solution. As a result, the equation has no answers.

Answer:

45

Step-by-step explanation:

Since

5 : 225 = 1 : X

Then we know

225/5 = X/1

Multiplying both sides by 1 cancels on the right

1 × (225/5) = (X/1) × 1

1 × (225/5) = X

Then solving for X

X = 1 × (225/5)

X = 45

Therefore

5 : 225 = 1 : 45

Answer:45

Step-by-step explanation:well all you do is divide 5 from 225

On solving the provided question, we can say that we excluded example 2 above, a maximum of 3 triangles can be created with those rods.

A triangle is a polygon since it has three sides and three vertices. It is one of the basic geometric shapes. The name given to a triangle containing the vertices A, B, and C is Triangle ABC. A unique plane and triangle in Euclidean geometry are discovered when the three points are not collinear.

\(2-inch, 3 inch, 4-inch\)

triangle, because 2+3 > 4, 2+4 > 3, and 3+4 > 2

\(2-inch, 3 inch, 5-inch\)

This is doesn't make  a triangle as  \(2+5 > 3, and 3+5 > 2,\)

2+3 is not more  than 5,, they cannot make triangle.

\(2-inch, 4 inch, 5-inch\)

triangle, because 2+4 > 5, 2+5 > 4, and 4+5 > 2

\(3-inch, 4 inch, 5-inch\)

a triangle, because 3+4 > 5, 3+5 > 4, and 4+5 > 3

Therefore, since we excluded example 2 above, a maximum of 3 triangles can be created with those rods.

Answer:

Let's define the variables:

x = yards of Organza ribbon that you buy.

y = yards of Satin ribbon that you buy.

We know that the price per yard of Organza ribbon is $0.07, this means tat if you buy x yards, the cost will be:

C = x*$0.07

And the cost of the Satin ribbon is $0.04, so if you buy y yards of that ribbon, the cost will be:

C = y*$0.04

Adding that together, the total cost is:

C = x*$0.07 + y*$0.04

Now we know that you pay $5, this means that the total cost is exactly $5, then we have the equation:

$5 = x*$0.07 + y*$0.04

Now we can isolate the variable y to get:

y = ($5/$0.04) - x*($0.07/$0.04)

y = 125 - x*1.75

Now we can just input different values of x to find the correspondent value of y.

This means that:

if x = 0 (0 yards of the Organza ribbon)

then:

y = 125 - 0*1.75 = 0

This combination is:

0 yards of organza, and 125 yards of satin.

Now, if x = 20, then:

y = 125 - 20*1.75  = 90

This combination is:

20 yards of organza, and 90 yards of satin.

if x = 40, then:

y = 125 - 40*1.75 = 55

This combination is:

40 yards of organza, and 55 yards of satin.

The 3 combinations that we found cost exactly $5.

The amount of money that Ben gets is £140.

Let's denote the amount Abby gets as 2x. Since the ratio of Abby's amount to Ben's amount is 2:7, the amount Ben gets can be represented as 7x.

Chloe and Denesh each get 1.5 times the amount Abby gets, which means they each get 1.5 * 2x = 3x.

The total amount shared between Abby, Ben, Chloe, and Denesh is £360. So we can write the equation: 2x + 7x + 3x + 3x = £360.

Simplifying the equation, we have: 15x = £360.

Dividing both sides by 15, we find that x = £24.

Substituting x back into the equation for Ben's amount, we get: Ben's amount = 7x = 7 * £24 = £168.

Therefore, Ben gets £140.

Answer:

the answer to the question is 1

The investment's expected return is 5.95%.

The expected return of an investment is calculated by multiplying the probabilities of each possible return by their respective returns and summing them up. In this case, Gautney Enterprises has provided the probabilities and returns for the investment. By applying the formula, we find that the expected return is 5.95%.

To calculate the standard deviation, we need to determine the variance first. The variance is computed by taking the difference between each possible return and the expected return, squaring those differences, multiplying them by their respective probabilities, and summing them up. Once we have the variance, the standard deviation is simply the square root of the variance. The standard deviation measures the degree of risk associated with an investment.

In this scenario, the expected return of the investment is 5.95%, but we need to consider the standard deviation as well to assess the risk. If the standard deviation is high, it indicates a greater level of uncertainty and potential volatility in returns. A low standard deviation implies a more stable investment.

Without the specific values for each return and their respective probabilities, we cannot calculate the exact standard deviation. However, Gautney Enterprises should compare the calculated expected return and the associated standard deviation to their risk tolerance and investment objectives. If the expected return meets their desired level of return and the standard deviation aligns with their risk appetite, they may consider investing in this security.

Explanation:

15+35.50 = 50.50 dollars is the total before tax is applied.

Take 8.25% of this to get

0.0825*50.50 = 4.16625

and this rounds to 4.17, which is the amount of sales tax charged.

$4.17 = 4 dollars + 17 cents

---------

Extra info:

The grand total will be 50.50+4.17 = 54.67

Another way to get the grand total is to multiply 1.0825 by the previous subtotal (50.50) getting 50.50*1.0825 = 54.66625 and that rounds to 54.67

The multiplier 1.0825 effectively means "increase by 8.25%"

Chang only wanted to spend $44, and the boat costs $8/hr. So, the variable would only be 8t, and you would put 44 on the other side.

Then, you'd put -4 on the side with 8t, because you can take off $4.

So, the setup would be;

44 = 8t - 4.

The amount of money left with K Maria is $245.08.

K Maria had $469.38. She gave $99.37 to Mike and $124.93 to Kerry. How much money is left with her?

K Maria had $469.38.

She gave $99.37 to Mike and $124.93 to Kerry.

We will need to find the difference between the total money K Maria had and the money given to Mike and Kerry. Therefore, the amount of money left with her can be calculated as follows;

Total money that K Maria gave out;= $99.37 + $124.93= $224.30

The amount of money left with K Maria can be found by subtracting the money she gave out from the total money she had initially;

Amount of money left with K Maria;= $469.38 - $224.30= $245.08

Therefore, the amount of money left with K Maria is $245.08.

The utilitarian hedonistic calculus is a system that attempts to determine the morality of an action based on its overall utility and the resulting pleasure or happiness it produces. The factors that are considered in this calculus include the intensity, duration, certainty or uncertainty, propinquity or remoteness, fecundity, purity, and extent of the pleasure or pain that will result from the action.

However, there is one factor that is not considered in the utilitarian hedonistic calculus, and that is the individuality of the persons involved. This means that the calculus does not take into account the unique qualities, desires, and preferences of the individuals affected by the action. Instead, it treats them all as if they were interchangeable and equally capable of experiencing pleasure or pain.

This lack of consideration for individuality has been criticized as a weakness of the utilitarian hedonistic calculus, as it can lead to outcomes that are unfair or unjust. For example, the calculus might suggest that it is acceptable to sacrifice the happiness of a minority group for the greater good of the majority, even if this violates their rights and dignity as individuals.

In summary, the utilitarian hedonistic calculus does not factor in individuality as a consideration in determining the morality of an action.

B.) This is not a binomial experiment, because the number of trials is not fixed.

Step-by-step explanation:

For a certain experiment to be classed as a binomial, it has to meet some criteria ;

Which include ;

1.) The trials should be independent.

11.) Each trial should be classifiable into one of success of failure.

111). There is a fixed mean probability for success and failure

IV) There is a fixed number of trials, in experiment described above, the number of trials isn't fixed, it is variable, as the trial will continue until a defective item is obtained.

\( \csc(82.4^\circ) \approx \frac{1}{0.988} \approx 1.012 \) (rounded to three decimal places). The solutions to the equation \( \frac{x-1}{3} = \frac{5}{x} + 1 \) are \( x = 5 \) and \( x = -3 \).

Using a calculator, we find that \( \sin(82.4^\circ) \approx 0.988 \) (rounded to three decimal places). Therefore, taking the reciprocal, we have \( \csc(82.4^\circ) \approx \frac{1}{0.988} \approx 1.012 \) (rounded to three decimal places).

Now, let's solve the equation \( \frac{x-1}{3} = \frac{5}{x} + 1 \) for \( x \):

1. Multiply both sides of the equation by \( 3x \) to eliminate the denominators:

  \( x(x-1) = 15 + 3x \)

2. Expand the equation and bring all terms to one side:

  \( x^2 - x = 15 + 3x \)

  \( x^2 - 4x - 15 = 0 \)

3. Factorize the quadratic equation:

  \( (x-5)(x+3) = 0 \)

4. Set each factor equal to zero and solve for \( x \):

  \( x-5 = 0 \) or \( x+3 = 0 \)

This gives two possible solutions:

  - \( x = 5 \)

  - \( x = -3 \)

Therefore, the solutions to the equation \( \frac{x-1}{3} = \frac{5}{x} + 1 \) are \( x = 5 \) and \( x = -3 \).
