Using the table the quadratic equation is y = x² - 2

from the curve the quadratic equation is y = x² + 1

Quadratic equation is written of the form

y = a(x - h)² + k

from the table the vertex is

v(h, k) = v(0, -2)

substituting the values to the formula

y = a(x - 0)² - 2

y = ax² - 2

Using the point (2, 2) from the table

y = ax² - 2

2 = a * 2² - 2

2 = 4a - 2

4a = 2 + 2

4a = 4

a = 1

The equation of the curve is

y = x² - 2

from the graph the vertex is

v(h, k) = v(0, 1)

substituting the values to the formula

y = a(x - 0)² + 1

y = ax² + 1

Assuming a unit on the graph is a unit we take point (1, 2) where the curve passed

A shooter has a 27.92% chance of hitting the target at least 13 times.

This probability mass function in this type of binomial distribution is the quantity of successes ("x").

P(X = x) = ⁿCₓ . pˣ . qⁿ⁻ˣ

The required number of wins is five since we are concerned with the likelihood that target will be hit exactly five times.(i.e., x = 13).

P(X = 13) =  ¹⁵C₁₃. (0.89)¹³ (0.11)²

P(X = 13) = 0.2792

P(X = 13) = 27.92%

Therefore, there is a 27.92% chance that a shooter will hit its target at the very most 13 times.

The area of the polygons sorted in ascending order of area is:

Rectangle  = 4

Triangle = 12

Square = 13

In geometry, a polygon is a planar shape defined by a restricted number of straight line segments linked to form a closed polygonal chain.

Area of the triangle is:

[Ax(By - Cy) + Bx(Cy - Ay) + Cx(Ay - By)]/2

Where Ax and Ay are the x and y coordinates of A's vertex. The same is true for the x and y notations of the B and C vertices.

Given,

A(-4-3), B(1, -3), C(-1,2)

We have

[-4(-3-2) + (1(2-(-3)) + (-1(-2-(-3))]/2

= 24/2

= 12

As a result, the area of the triangle is 12.

We use the distance formula to calculate the area of the rectangle. The equation is as follows:

d² = (x₂ - x₁)² + (y₂-y₁)²

Where (x₁, x₂) are the first point's coordinates and (y₁, y₂) are the coordinates of the second point.

Assuming that the vertices are labeled as follows:

A(7,9), B(6,9), C(6,5), D(7,5), then

AB² = (6-7)² + (9-9)²

AB² = 1 + 0

AB = 1

BC² = (6-6)² + (5-9)²

BC² = 0² + -4²

BC = 4

CD² = (7-6)² +(5-5)²

CD² = 1² + 0²

CD = 1

DA² = (7-7)² + (9-5)²

DA² = 0² +4²

DA = 4

As is typical of a rectangle, we can deduce that AB = CD and BC = DA

Since the Area of the rectangle is AB x CD OR BC x DA

The area of the rectangle =4 x 1 = 4

We may also calculate the length of the square's sides using distance methods.

We only need the length of one side because the area of a square is provided as L2.

Hence,

AB = 3.60555

Hence the area of the square =3.60555²

= 12.9999908025

Area of the square is 13

Thus, the polygons are placed in increasing area order as follows:

Rectangle = 4

Triangle = 12

Square = 13

True, With an 80-person sample size, we are selecting from a skewed-right distribution, hence the sampling distribution mean should likewise be skewed-right.

80 people make up the sample that was taken from the population distribution with a right skew. We may infer that the sampling distribution of the sample means would be close to normalcy given the size of the sample.

In general, the distribution is normal.

The central limit theorem states that as sample size increases, the sample mean distributions become normal, with standard deviations equaling n and mean values approximating the population mean, regardless of the underlying distribution's form. In other words, the sample means sampling distribution turns roughly normal.

Given that:

2Ax = 0.08

Ax = 0.2

A fully discrete whole life insurance issued to (x) is 1000.

Firstly we have to find out the value of variance S.

Variance S = (insurance issued)^2 * [2Ax - Ax^2]/(1- Ax)^2

Variance S = (1000)^2 * [0.08 -  0.2^2]/(1- 0.2)^2

Variance S = (1000)^2 * [0.04]/.64

Variance S = (1000)^2 * .0625

Variance S = 62500

Standard deviation of S = (insurance issued) * [[tex]\sqrt{2Ax - Ax^2}[/tex]]/(1- Ax)

Standard deviation = 1000 * [[tex]\sqrt{0.08 - 0.2^2}[/tex]]/(1- 0.2)

Standard deviation = 1000 * 0.2/0.8

Standard deviation = 1000 * 1/4 = 250

4 to 8 hours or more are typical for active labor. Your cervix will expand on average at a rate of 1 cm per hour. What you can do: Seek encouragement and support from your labor partner and your medical team. To ease your discomfort, try deep breathing and relaxation exercises.

Given:

Longobardi corporation bases its predetermined overhead rate on the estimated labor- hours for the upcoming year.

At the beginning of the most recently completed year, the corporation estimated the labor-hours for the upcoming year at 46,000 labor- hours.

The estimated variable manufacturing overhead was $6.25 per labor-hour and the estimated total fixed manufacturing overhead was $1,026,260.

The actual labor- hours for the year turned out to be 41,200 labor-hours.

Estimated total manufacturing overhead

= $1,026,260 + ($6.25 per labor- hour X 46,000 labor - hours)

= $1,313,760

Predetermined overhead rate

= $1,313,760 / 46,000 labor-hours

P(4, 7.25) are the coordinates of circumcentre of the triangle

The circumcenter of a triangle is the point where the perpendicular bisectors of the sides of that particular triangle intersect

Given: The vertices R(-2,5), S(-6, 5), T(-2,-1)​

Let P(x,y) be the circumcentre of triangle. Then,

PR = PS = PT

PR² = PS²

(x-(-2))² + (y-5)² = (x-(-6))² + (y-5)²

(x+2)² + (y-5)² = (x+6)² + (y-5)²

x²+4x+4 + y²-10y+25 = x²+12x+36 + y²-10y+25

12x-4x = 36 -4

8x = 32

x = 32/8 = 4

Also, PS² = PT²

(x-(-6))² + (y-5)² = (x-(-2))² + (y-(-1))²

(x+6)² + (y-5)² = (x+2)² + (y+1)²

x²+12x+36 + y²-10y+25 = x²+4x+4 + y²+2y+2

12x-4x-10y-2y = 4+2-36-25

8x-12y = -55 .......(1)

put x= 4 into (1):

8x-12y = -55

8(4)-12y = -55

32 -12y = -55

-12y = -55-32

-12y = -87

The amount of $34.65 is deducted from Ron’s gross wages for social security at 6.2% and Medicare at 1.5% .

Percentage means one part of every cent or hundred. And it is represented by symbol '%'.

Given that Ron earns $450 in gross wages on January 10.

To find deduction amount from Ron’s gross wages for social security at 6.2% ;

Firstly, we find  6.2% of $450 that is $450 x 6.2 / 100 = $27.9 and then we substract to the gross wages.

$450 - $27.9 = $422.1

Now to find 1.5 % of $450 that is 450 x 1.5/ 100 = $6.75 and then we substract to the gross wages.

$450 - $6.75 = $443.25

The required linear function in slope intercept form is C = 5x + 20

What is equation of line in slope intercept form?

The most general form of equation of line in slope intercept form is given by y = mx + c

Where m is the slope of the line and c is the y intercept of the line.

Slope of a line is the tangent of the angle that the line makes with the positive direction of x axis.

If [tex]\theta[/tex]  is the angle that the line makes with the positive direction of x axis, then slope (m) is given by

m = [tex]tan \theta[/tex]

The distance from the origin to the point where the line cuts the x axis is the x intercept of the line.

The distance from the origin to the point where the line cuts the y axis is the y intercept of the line.
