Using a system of equations, it is found that:

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are A and B.

51.5% of 227 million eligible voters voted, hence, considering millions as the unit measure:

A + B = 0.515 x 227

A + B = 117.

The equation for A in terms of B is given by: A = 117 - B.

Candidate A won the popular vote by 4.8 million votes, hence:

A = B + 4.8.

B + 4.8 = 117 - B

2B = 112.2

B = 61.1.

A = 61.1 + 4.8 = 65.9.

The decision-maker is advised to use three dummy variables. The rule of thumb states that it is better to use lesser dummy variables than the categories being investigated. In this case, the categories are four - North, South, East, and West.

This is a statistical term that refers to a factor that is characterized with the value of one or zero in order to explain the presence of absence of an effect that is categorized.

This is used mainly in regression analysis.

Answer:

250m^2

Step-by-step explanation:

Area of quadrilateral = ½ × diagonal length × sum of the length of the perpendiculars drawn from the remaining two vertices

We can substitute the numbers given into the formula shown above.

1/2 * 25 * (8+12)m^2

This can be simplified to 1/2 * 25 * 20 which is 250m squared

Answer:

[tex]\huge\boxed{(12,80),(10,65)}[/tex]

Step-by-step explanation:

The line given has a slope of 7.5 and a point at (12, 80)

Because of the slope, simply subtract 2 from the x and subtract 15 from the y to get another point, at (10, 65)

Thus, simply put your points at (10, 65) and (12, 80)

Answer:

Step-by-step explanation:

yes....the pair of linear equations has unique solution.....

2x + 3y - 7 = 0 ...... (i)

3x + 2y + 10 = 0 ....... (ii)

on comparing the equation i nd ii with a1x + b1y + c1 = 0

nd a2x + b2y + c2 = 0 reslectively......

a1 = 2 ; b1 = 3 ; c1 = -7

a2 = 3 ; b2 = 2 ; c2 = 10

here....its clear that......

a1 / a2 is not equal to b1 / b2

Therefore the given pair of linear equation have a unique solution........

Answer:

[tex]f(x) = \dfrac14(x + 1)^2(x + 3)(x -2)( x - 3)[/tex]

Tia is correct

Step-by-step explanation:

From inspection of the graph, we can say that the leading coefficient of the function is positive as:

[tex]f(x) \rightarrow - \infty, \textsf { as } \ x \rightarrow - \infty\\f(x) \rightarrow +\infty, \textsf { as } \ x \rightarrow + \infty[/tex]

From inspection of the graph, we can see that the curve intercepts the x-axis at x = -3, x = 2, x = 3

As the curve touches the x-axis at (-1, 0) then this means that the root x = -1 has multiplicity 2

Therefore, [tex]f(x) = a(x + 1)^2(x + 3)(x -2)( x - 3)[/tex] where [tex]a[/tex] is some positive constant.

If we multiply the constants, we can determine the y-intercept:

y-intercept = a x 1² x 3 x -2 x -3 = 18a

Therefore, the y-intercept is at y = 18a

From inspection of the graph, the y-intercept is at y = 4.5

So to determine the value of a:  18a = 4.5 ⇒ a = 1/4

Therefore, the fully factored form of the equation is:

[tex]f(x) = \dfrac14(x + 1)^2(x + 3)(x -2)( x - 3)[/tex]

Step-by-step explanation:

Have a good day :)

Answer:

Step-by-step explanation:

Perimeter of the square is 24(4)=96.

Perimeter of the rectangle is 2(10+length)=96

10+length=48

length=38 m

Area of the square is 24^2 = 576.

Area of the rectangle is 10 * 38 = 380

So the square has an area 196 m^2 greater.

Answer:

Step-by-step explanation:

The gross pay that shows up on your paycheck is the sum of wages, commissions, and any other earnings your employer may share with you (tips, insurance offsets, bonuses). From this gross pay, government regulations may require the deduction of taxes of various kinds. Your employer may deduct the cost of insurance, and you may voluntarily have amounts deducted for additional taxes, insurance, union dues, or retirement plan contributions. The pay that you take home is the net pay after these deductions.

__

Chien gets paid at the rate of $15 per hour for 20 hours per week and 2 weeks per pay-period. We are not told of any other earnings or contributions to his gross pay. So, it will be ...

  ($15/h)(20 h/wk)(2 wk/period) = $600/period

Chien's gross pay will be $600 each pay period.

__

As discussed above, "net pay" and "take-home pay" are synonymous.

__

As discussed above, there may be a variety of deductions from his gross pay that will reduce his net pay. Often the largest of these is income tax together with Social Security tax. There may be additional deductions for insurance, union dues, health plan contributions, and retirement plan contributions.

__

Chien's budget should be based on money he actually has available to spend. That would generally be his net pay.

If Chien is considering changing jobs or his family situation, changes to payroll deductions may figure into his budget. Ordinarily, those costs would be considered "fixed" and not subject to a budgeting process.

Answer:

6. mean = 1.4

7. variance = 1.64

standard deviation = √1.64

Step-by-step explanation:

6.  

[tex]\textsf{mean }\mu=\[ \sum [x \cdot p(x)][/tex]

⇒ [tex]\mu[/tex] = 0 x 0.4 + 1 x 0.1 + 2 x 0.2 + 3 x 0.3 = 1.4

7. see attached for completed table

[tex]\textsf{variance }\sigma^2=\[ \sum [(x -\mu)^2 \cdot p(x)][/tex]

Therefore, variance is the total of the last column:

[tex]\sigma^2[/tex] = 0.784 + 0.016 + 0.072 + 0.768 = 1.64

standard deviation is the square root of variance:

[tex]\sigma=\sqrt{1.64}[/tex]

Answer:

324 square feet (or whatever you call it i don't use feet and inches lol)

Step-by-step explanation:

We gotta divide this into a trapezoid and a rectangle.

the rectangle part is easy which is 6x18=108

Then the trapezoid

b1=6 b2=18 h=18

6+18=24

24x18=432

432/2=216

now we add them 216+108=324
