The M(x) or the estimate slope is 20.23X

A regression equation is used in stats to find out what relationship, if any, exists between sets of data. For example, if you measure a child’s height every year you might find that they grow about 3 inches a year. That trend (growing three inches a year) can be modeled with a regression equation.

[tex]Y_i=f(X_i, \beta)+e_i[/tex]        [tex]Y_i[/tex] = dependent variable

[tex]X_i[/tex] = independent variable

[tex]\beta[/tex] = unknown parameters

[tex]e_i[/tex] = error terms

Given here,  Y=20.23*X+516.1

Thus comparing it with the equation above we can deduce that

M(x) = 20.23x

Hence The M(x) or the estimate slope is 20.23X

The required value of y is obtained as -2.

The given system of equation can either have a unique solution, more than one solutions or no solution.

On this basis they are divided into two parts consistent and inconsistent.

A consistent system has one or more solutions while for an inconsistent system there are no solutions.

The given system of equations is as below,

4x - y = 10             (1)

x - 4 = y               (2)

Substitute the value of y from equation (2) into equation (1) to get,

4x - (x - 4) = 10

=> 3x + 4 = 10

=> 3x = 6

=> x = 2

Then, substitute x = 2 in  x - 4 = y  to get,

y = 2 - 4  = -2

Hence, the value of y for the given system of equations is -2.

Here,

Part A:

Jamal works as a valet made $10.25 an hour and an additional $50.10 in tips,

Thus number of hours be x

equation : 10.25x + 50.10 =0

or

Jamal works as a waiter made $6.75 an hour and an additional $125 in tips

equation : 6.75x + 125 = 0

Part B:

The total amount he made when both paychecks are same

=> 6.75x + 125 = 10.25x + 50.10

=> 10.25x-6.75x = 125-50.10

=>3.5x = 74.9

The composite function (f + g)(x) is (f + g)(x) = 9x² - x - 8

From the question, we have the following parameters that can be used in our computation:

f(x)=3x²+42-6

g(x)=62-5²-2

Express properly

So, we have the following representation

f(x) = 3x² + 4x -6

g(x) = 6x² - 5x - 2

The composite function is then calculated as

(f + g)(x) = f(x) + g(x)

So, we have

(f + g)(x) = 3x² + 4x -6 + 6x² - 5x - 2

(f + g)(x) = 9x² - x - 8

5. the most significant challenge that small businesses face is financial problems.

The primary purpose of the passage is to caution against uncritical embrace of nuclear fusion power as a major energy source.

Nuclear fission generates a significant amount of radioactive waste, which can be hazardous and needs to be stored securely for a long period of time. Nuclear fusion waste has a lower radioactivity and decays significantly more quickly. Fossil fuels like gas and oil are not required for nuclear fusion.

Radiation that is released voluntarily is referred to as radioactivity. An atomic nucleus that is unstable for some reason accomplishes this by "wanting" to give up some energy in order to change its configuration to one that is more stable.

The passage begins by classifying as misconceptions favorable views about nuclear fusion power and finishes by recommending the use of current energy sources going forward rather than nuclear fusion power.

Answer:  5 4/15

Step-by-step explanation:

1 3/5 + 3 2/3 = 8/5 + 11/3

Find the common denominator (5 and 3) = 15

So 8/5 equals to 24/15 because if 5 x 3 = 15 , 8 must also multiply by 3.

11/3 equals to 55/15 because if 3 x 5 = 15 , 11 must also multiply by 5.

Thus 24/15 + 55/15 = 79/15

This is an improper fraction, so converting to mixed number:

79/15 = 5 4/15 because 5 x 15 + 4 = 79

The amount of the last payment that Elroy will make is $710, which includes the $200 monthly payment and a balance of $510.

The last payment amount is the result of the mathematical operations of subtraction and multiplication.

The first mathematical operation was the subtraction of the down payment from the total cost of the video game system.

Using multiplication, the monthly payments are determined to be $3,400 for 17 months.  This is subtracted from the remaining balance to obtain the last payment amount.

The cost of a custom video game/virtual sound system = $4,210

Down payment = $100

The remaining balance for monthly payment = $4,110 ($4,210 - $100)

Payment period = 18 months (1¹/₂ years)

Monthly payments = $200

Payment for the first 17 months = $3,400 (17 x 200)

Last payment = $710 ($4,110 - $3,400)

Thus, if Elroy makes the minimum monthly payment of $200 till the last payment, then he will pay $710 to settle the account.

Answer:

Step-by-step explanation:

To solve the equation 3(x+1) = 4x-1, we need to use the rules of algebra to isolate the variable "x" on one side of the equation and simplify the other side.

First, we can distribute the 3 on the left side of the equation to obtain 3x + 31 = 4x-1. This gives us 3x + 3 = 4x-1.

Next, we can subtract 3x from both sides of the equation to obtain 3 + 3 = 4x-1-3x. This simplifies to 3 = x-1.

Now we can add 1 to both sides of the equation to obtain 3+1 = x. This gives us the final solution x = 4.

Therefore, the solution to the equation 3(x+1) = 4x-1 is x = 4.

What is a regulars polygon?

A regular polygon is denoted a area. The area bounded by equal length of arms. The angel between any two consecutive arms will same any other pair of consecutive arms.

The number of line of symmetry of a polygon is the same is the number of arm or sides of that polygon.

Thus the number of sides of a polygon that has 12 lines of symmetry is 12.

The angle of rotational symmetry of a polygon is 360°/n, where n is the number of arms.

Therefore,

Angle of rotational symmetry = 360°/n

Putting Angle of rotational symmetry = 24°:

24° = 360°/n

Multiply both sides by n

24n = 360
