To solve this problem, we should write a system of linear equations;

Let;

3x + 2y = 610 ...eq(i)

y - 10 = 2x ...eq(ii)

From equation (ii)

y = 2x + 10 ...eq(iii)

Put eq(iii) into equ(i)

3x + 2(2x + 10) = 610

3x + 4x + 20 = 610

x = 590/7 = 84.3

Put x = 84.3 into equ(ii)

y - 10 = 2(84.3)

y = 1250 / 7

y = 178.6

The percentage of higher risk is unaffected by exposure as relative risk in unity.

In order to determine the strength of the relationship between exposures (treatments or risk factors) and outcomes, relative risk is employed in the statistical analysis of data from ecological, cohort, medical, and intervention studies. For instance, in a study looking at how the drug apixaban affected the occurrence of thromboembolism, 8.8% of patients receiving a placebo developed the condition, whereas only 1.7% of patients receiving the medication did. This means that the relative risk is.19 (1.7/8.8), meaning that patients receiving apixaban had 19% the disease risk of patients receiving a placebo. [4] In this instance, apixaban lowers the probability of disease, making it a protective rather than a risk factor.

Values of relative risk can be understood as long as the relationship between the exposure and the result is assumed to be causal.

RR = 1 denotes that the outcome is unaffected by exposure.

When the risk of the outcome is less than 1, this is referred to as a "protective factor."

RR > 1 indicates that the exposure, a "risk factor," has an effect on the outcome's risk.

Therefore, the percentage of higher risk is unaffected by exposure as relative risk in unity.

The result of DNA replication, given the fact that most cancer cases came as a result of DNA replication errors, is C. A chromosome with two identical DNA strands is formed.

The biological process of creating two identical copies of DNA from a single original DNA molecule is known as DNA replication.

After this process is complete and all the DNA has been copied, the cell actually has twice as much DNA as it needs, which it can then divide and parcel into the daughter cell, resulting in the daughter cell and the mother cell being nearly genetically identical in many cases.

Volume of solid generated by revolving the region bounded by the graph is 3817.53 unit

A volume is created while a plane figure rotating about an axis or around any straight line situated on the same plane.

We apply definite integration to calculate the required volume.

we are given the equation y = 5x² and y =0, x= 3

volume is calculated by using the formula, V = ∫π y² dx

                                                                      V = ∫₀³π (5x²) ² dx

On the y-axis x = 0 so upper limit x = 3 and lower limit x= 0

                                                          V= π × 25/5 [x⁵] ³₀

1. The solution to the quadratic equation, x² - 14x + 49 = 40, is x = 13.32 and x = 0.68

2. The solution to the quadratic equation, x² - x = 12, is x = -3 and x = 4

3. i. The factors of 2x² - 15x - 8 = 0 are (2x +1) and (x - 8)

ii. The x-intercepts of 2x² - 15x - 8 = 0 are x = -1/2 and x = 8

From the question, we are to solve the given quadratic equation by completing the square.

The given equation is

x² - 14x + 49 = 40

Solving the equation

x² - 14x + 49 = 40

x² - 14x = 40 - 49

x² - 14x = -9

Multiply the coefficient of x by 1/2 square and add to both sides

x² - 14x + (-7)² = -9 + (-7)²

(x - 7)² = -9 + 49

(x - 7)² = 40

x - 7 = ±√40

x = 7 ± √40

x = 7 ± 6.32

x = 7 + 6.32 OR 7 - 6.32

x = 13.32 OR 0.68

Solving x² - x = 12 by factoring

x² - x = 12

x² - x - 12 = 0

x² -4x + 3x - 12 = 0

x(x - 4) + 3(x - 4) = 0

(x + 3)(x - 4) = 0

x + 3 = 0 OR x - 4 = 0

x = -3 OR x = 4

Determining the factors of 2x² - 15x - 8 = 0

2x² - 15x - 8 = 0

2x² - 16x + x - 8 = 0

2x(x - 8) + 1(x - 8) = 0

(2x + 1)(x - 8) = 0

The factors are (2x +1) and (x - 8)

Determining the x-intercepts

(2x + 1)(x - 8) = 0

2x + 1 = 0 and x - 8 = 0

2x = -1 and x = 8

x = -1/2 and x = 8

Hence, the x-intercepts are -1/2 and 8

Answer:

The following equations are true when 3.27 is used:

÷ 1,000 = 0.0327

÷ 10 = 0.327

÷ 100 = 3.27

Note that the equations ÷ 102 and ÷ 1 are not true when 3.27 is used. The equation ÷ 102 is not true because 102 is not a multiple of 1,000, so dividing 3.27 by 102 will not result in a value that is close to 0. The equation ÷ 1 is not true because it is simply stating that 3.27 divided by 1 is equal to 3.27, which is true but not very interesting or useful.

The number of belts produced must be positive: X1, X2, X3 >= 0

The shadow price of a constraint can be understand as the change in the objective function value for a unit change in the right-hand side (RHS) value of the constraint, with all other variables held constant.

A constraint is a condition of an optimization problem that should be satisfied the condition.

Here we can formulate this problem as a linear programming model (LPM):

Consider X1 be the number of belt A produced per day

Let X2 be the number of belt B produced per day

Let X3 be the number of belt C produced per day

The objective function is to maximize the profit, that is;

3X1 + 5X2 + 4X3.

The constraints are as follows:

The time spent on machine M1 must be less than or equal to 8 hours per day then;

2X1 + 3X2 <= 8

The time spent on machine M2 must be less than or equal to 10 hours per day then;

3X1 + 2X2 + 5X3 <= 10

The time spent on machine M3 must be less than or equal to 15 hours per day then we have

2X1 + 2X2 + 4X3 <= 15

Thus number of belts produced must be positive:

X1, X2, X3 >= 0

To solve this LPM using the simplex algorithm, you can follow these steps:

w In standard form, the objective function is to minimize the cost, and all constraints are in the form of "less than or equal to" a certain value.

The pivot row is the row that corresponds to the smallest positive ratio between the right-hand side (RHS) value and the corresponding pivot column element the constraint 2X1 + 3X2 ≤ 8.

Now Interpret the shadow prices.

The shadow price of a constraint can be understand as the change in the objective function value for a unit change in the right-hand side (RHS) value of the constraint, with all other variables held constant.

It can help to understand the value of the constraints in the LPM and how they contribute to the optimal solution.

⭐ What is the equation of a line in slope intercept form?

The given line of best fit is written in slope-intercept form. All we have to do is identify which term is the slope.

[tex]y = -3x + 5[/tex]

-3 is the coefficient of x. Therefore, -3 is the slope.

The equation of line in slope in intercept form will be equal to y = 4x - 4.

It is possible to determine a line's direction and steepness by looking at its slope. Finding the slope between lines inside a coordinate plane can aid in anticipating if the lines are perpendicular, parallel, or none at all without physically using a compass.

As per the data provided in the question,

The formula for a line is y = mx + b, where m denotes the slope and b the y intercept.

The linear equation that represent the total cost after x month is y = 35 + 29.95x.

What is linear equation?

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."

Given that, a cable operator offer at $29.95 per month plus a one-time installation fee.

Assume that, a be one time installation fee.

After x month, they need to pay without one-time installation fee is 29.95x.

The total amount that need to pay after x month is a + 29.95x

The linear equation that represents total cost after x month is

y = a +  29.95x

Putting y = 214.70 and x = 6

214.70 = a +  29.95 × 6

214.70 = a +  179.70

a = 35.
