There is 14.8 grams of sugar are there in a 200 ml glass of juice.

For the given question,

There are 18.5 gram of sugar in 250 ml of glass of juice.

This can be written as;

250 ml ------> 18.5 grams of sugar.

For 1 ml of the glass of juice, divide both sides by 250.

1 ml ------> 18.5/250 grams of sugar.

For 200 ml of the glass of juice, multiply both sides by 200.

200 ml ------> 18.5×200/250 grams of sugar.

200 ml ------> 14.8 grams of sugar.

Thus, 14.8 grams of sugar are there in a 200 ml glass of juice.

Answer:

x=4

Step-by-step explanation:

first you would factor the -2(2x-1). -2x2x= -4x, -2x-1= 2

the equation would then be 5x-4x+2=6

add the x's together which turns the equation to 1x+2=6

minus 2 from both sides of the equation which gives you x=4

The required value of x would be 4 in the given equation 5x − 2(2x − 1) = 6.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

We have to determine the value of x in the equation

Given that the equations as :

⇒ 5x − 2(2x − 1) = 6

Open the parentheses and apply the multiplicative property,

⇒ 5x - 4x + 2 = 6

Apply the subtraction operation in the terms of x

⇒ x + 2 = 6

⇒ x = 6 - 2

⇒ x =  4

Therefore, the required value of x would be 4 in the equation

Answer:

İt is solved by using derivative

The edges of box are 20–2x,15–2x and x

Volume=(20–2x).(15–2x).x

İf you take derivative and then find the roots of derivative we obtain exstramum points that means these values make volume maximum or minimum

But

Answer is not rational

Answer:

A = 300-x^2 for area

A = 20L * 15 -x^2   for area

20L - x^2 = 300 - x^2 /15 -x^2 could also work to find length .

SIMPLIFIED

L - x = 300/20 -  ( x^2 )/ 15 - x

Step-by-step explanation:

Length = L = 20 inches.

Area of one side = A = 15 X 20 = 300 cm^2

= 300 - x^2  

This means the missing corner square is also squared

Simplifies to sqrt 300 - x

but as length was asked 20L * 15 -x^2

we know one side may be 15x 15

and if one side is 15 x 20

then instead of 15 x 15 it may be 15 x 20

eitherway we are looking at one side representing area of one side of the box. 300-x is our answer.

Bayesian regression with undirected network predictors offers a powerful framework for analyzing brain connectome data and gaining a deeper understanding of the relationships between brain connectivity and various outcomes of interest.

Bayesian regression with undirected network predictors refers to a statistical modeling approach that combines Bayesian inference principles with regression analysis when the predictors are represented as an undirected network. This approach is particularly useful when dealing with data that has a network structure, such as brain connectome data.

In the context of brain connectome data, a connectome represents the structural or functional connectivity between different regions or nodes of the brain. Each node can be seen as a predictor variable, and the relationships between nodes are represented by edges in the network.

Bayesian regression allows for flexible modeling of the relationships between predictors and the response variable, taking into account uncertainty in the parameter estimates. By incorporating the network structure of the predictors, Bayesian regression with undirected network predictors can capture complex dependencies and interactions among brain regions, providing insights into the relationships between brain connectivity and the outcome of interest.

Using the distance formula, the distance from point Q to point R is 12 units.

The distance from point Q to point R can be calculated using the distance formula:

distance = √((x2 - x1)^2 + (y2 - y1)^2)

We are told that:

Point Q is located at (-4, 6).

Point R is located at (8,6).

Therefore, we would have the following, where we have the given parameters:

(x1, y1) = (-4, 6)

(x2, y2) = (8, 6)

Distance between the two points (QR) = √((8 - (-4))^2 + (6 - 6)^2) = √(144 + 0) = √(144) = 12 units

1. Total revenue formula: Rx = 10,000x^(3/2)/(2+√x). 2. Marginal revenue formula: MR(x) = R′(x). 3. MR(9) calculation.


To find the marginal revenue (MR) and evaluate MR(9), we first need to understand the total revenue formula and how to calculate the derivative of this formula.

1. Total revenue formula (Rx):
The total monthly revenue from the sale of x automobiles of a certain model is given by:
Rx = 10,000x^(3/2)/(2+√x)
2. Marginal revenue formula (MR):
The marginal revenue (MR) is calculated by taking the derivative of the total revenue formula, Rx.
3. MR(9) calculation:
To find MR(9), we substitute x = 9 into the derivative formula of Rx.

Now, let's calculate the MR(9) step by step:
Step 1: Find the derivative of Rx:
To find the derivative, we need to apply the power rule and chain rule.
The derivative of Rx with respect to x is given by:
R′(x) = (d/dx) [10,000x^(3/2)/(2+√x)]
Step 2: Simplify the derivative:
To simplify the derivative, we can use the quotient rule and the power rule.
R′(x) = [10,000 * ((2+√x) * (3/2) * x^(1/2)) - (10,000 * x^(3/2) * (1/2) * (√x))] / (2+√x)^2
Simplifying further:
R′(x) = [15,000x^(3/2) + 5,000x - 10,000x^(3/2)√x] / (2+√x)^2
Step 3: Calculate MR(9):
Substitute x = 9 into the derivative formula.
MR(9) = [15,000(9)^(3/2) + 5,000(9) - 10,000(9)^(3/2)√9] / (2+√9)^2
Simplifying:
MR(9) = [15,000(27) + 5,000(9) - 10,000(27)√9] / (2+3)^2
MR(9) = [405,000 + 45,000 - 270,000] / 25
MR(9) = 180,000 / 25
MR(9) = 7200
Therefore, MR(9) = 7200.

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.

Answer: 102

Step-by-step explanation:

Let the number of adults tickets be represented by x

Let the number of children tickets be represented by y.

We can then form an equation which will be:

x + y = 259 ....... i

6x + 5y = 1397 ...... ii

From equation i, y = 259 - x ...... iii

Put equation iii into ii

6x + 5y = 1397

6x + 5(259 - x) = 1397

6x + 1295 - 5x = 1397

Collect like terms

6x - 5x = 1397 - 1295

x = 102

Since Mary and Max are playing a game with complex numbers, Max's score must be equal to 1/(3 + 2i), so that the product of their score is one.

A reciprocal function simply refers to a type of function which comprises a constant on its numerator and an algebraic expression or complex number in its denominator such as: f(x) = 2/3 + 7i.

In Mathematics, a reciprocal function is typically used when describing relationships that are inversely proportional to one other.

Let the variable n represent Max's score. Therefore, a mathematical expression which models the product of both Mary and Max's score is given by the following:

Product = 3 + 2i × n = 1

Making n the subject of formula, we have the following as Max's score;

n = 1/(3 + 2i)

3 + 2i × 1/(3 + 2i) = 1

(3 + 2i)/(3 + 2i) = 1
