Earned income is said to be $35,000, Base tax amount at that level is $4386, The amount over $31850 is  $3150, Line 3 is multiplied by 25% is $787.50, The sum of lines 2 and 4 is $5173.50 and This amount divided by 12 is $431.13.

Two or more expressions with an Equal sign is called as Equation.

Given,

The given Federal Income Tax Table Single: Over But not over The tax is $0 $7,825 10% of the amount over $0 $7,825 $31,850 $788 + 15% of the amount over $7,825 $31,850 $77,100 $4,386 + 25% of the amount over $31,850 $77,100 $160,850 $15,699 + 28% of the amount over $77,100 $160,850 $349,700 $39,149 + 33% of the amount over $160,850 $349,700 And Over $101,469 + 35% of the amount over $349,700

Earned income is said to be $35,000.

Base tax amount at that level is $4386.

The amount over $31850 is $35000-31850 = $3150

Line 3 is multiplied by 25%: $3150×0.25 = $787.50

The sum of lines 2 and 4 is $4386 +787.50 = $5173.50

This amount divided by 12 is ... $5173.50/12 ≈ $431.13

Hence, Earned income is said to be $35,000, Base tax amount at that level is $4386, The amount over $31850 is  $3150, Line 3 is multiplied by 25% is $787.50, The sum of lines 2 and 4 is $5173.50 and This amount divided by 12 is $431.13.

The distance to the point is less than c=10, so the point is inside the circle.

Given that, (a, b) = (5, –2) and c = 10.

The domain and range are defined for a relation and they are the sets of all the x-coordinates and all the y-coordinates of ordered pairs respectively. For example, if the relation is, R = {(1, 2), (2, 2), (3, 3), (4, 3)}, then:

Domain = the set of all x-coordinates = {1, 2, 3, 4}

Range = the set of all y-coordinates = {2, 3}

Part A:

Use of the Pythagorean theorem gets you to the equation for a circle in essentially one step:

Sum of squares of sides = square of hypotenuse

(x -a)²+(y -b)² = c² circle centered on (a, b) with radius c.

Part B:

The circle will be defined for values of x in the domain f ± c, and for values of y in the range b ± c.

domain: 5 ± 10 = [5, -5]

Range: -2 ±10 = [8, -11]

Part C:

The distance from point (10, 2) to (a, b)=(5, -2) is

c² = (10-5)² +(-2-2)²

c² = 25+16

c² = 41

c=√41

c=6.4

The distance to the point is less than c=10, so the point is inside the circle.

Therefore, the distance to the point is less than c=10, so the point is inside the circle.

2 cups of milk relate to 6 1/4 cups of flour.

such recipes represent a direct dependency of one variable on the other. one variable is always the other variable multiplied by a constant factor.

m = cups of milk

f = cups of flour

m = n×f

2 = n×(6 1/4) = n×(6×4 + 1)/4 = n×25/4

8 = 25n

n = 8/25

now, f = 43 3/4 = (43×4 + 3)/4 = 175/4

so,

m = 8/25 × 175/4 = (8×175)/(25×4) = 2×7 = 14

you will need 14 cups of milk.

a. The numeric value at Thursday -> x = 4 is of 32 degrees, which agrees with the graph.

b. A numeric value of 35 degrees Fahrenheit is obtained on Monday and on Thursday, also agreeing with the graph.

To obtain the numeric value of a function or of an expression, we replace each instance of the variable in the function or in the expression by the value at which we want to find the numeric value.

In this problem, the function is defined as follows:

f(x) = 3x² - 18x + 56.

Giving the temperature in degrees Fahrenheit in x days after Sunday.

The day that represents Thursday is given by:

x = 4.

Hence the temperature is the numeric value of the function at x = 4, replacing both instances of x on the function by 4, hence:

f(4) = 3(4)² - 18(4) + 56 = 32 ºF.

Which agrees with the graph, as the Thursday's bar is a value slightly above 30, which can be interpreted as 32.

The numeric value is of 35 when:

3x² - 18x + 56 = 35

The solutions to the quadratic equation are:

x = 1.6, x = 4.4.

Hence the days are:

Monday and Thursday.

The dimensions of the rectangular window that gives a maximum area are as follows;

Width = [tex]\dfrac{12}{2+\pi }[/tex] feet and length = 3 feet

The maximum value of a function is given by the point at which the graph of the function has the highest value.

The parameters of the window are;

Length of the framing material available = 12 ft.

The shape of the window = A semicircle on top of a regular rectangular window

Required; The dimension of the rectangular part of the Norman window that allows the most light

Solution;

Diameter of the semicircular part of the window = The width of the rectangular part

Let x represent the width of the window, we have;

Perimeter of the semicircle = π·x/2

Side length of the rectangular window = (12 - π·x/2 - x)/2

Area of the rectangular part of the window, A = x × (12 - π·x/2 - x)/2

Area of the semicircle = π·x²÷4

Area of the window, is therefore;

[tex]A =\dfrac{ x \times (12 - \dfrac{\pi \cdot x}{2} - x)}{2} +\dfrac{ \pi \cdot x^2}{4}[/tex]

At the maximum area, of the rectangular part, we have;

[tex]A_r' =\dfrac{d}{dx}\left( A =\dfrac{ x \times (12 - \dfrac{\pi \cdot x}{2} - x)}{2} \right) = -\dfrac{x\cdot \pi +2\cdot x-12}{2} = 0[/tex]

x·π + 2·x - 12 = 0

The width, x = [tex]\dfrac{12}{2+\pi }[/tex] feet

The length of the rectangle is therefore;

[tex](12 - \pi \cdot \dfrac{6}{2+\pi } - \dfrac{12}{2+\pi })/2 = 6 - \pi \cdot \dfrac{3}{2+\pi } - \dfrac{6}{2+\pi } = 3[/tex]

The image of (12, -12) after a dilation by a scale factor of 1/4 ​centered at the origin would have these coordinates (3, -3).

In Geometry, dilation simply refers to a type of transformation which typically changes the size of a geometric object based on the scale factor applied, but not its shape.

Next, we would dilate the coordinates of the preimage (12, -12) by using a scale factor of 1/4 centered at the origin (0, 0) as follows:

Coordinate A (12, -12) → Coordinate A' (12 × 1/4, -12 × 1/4) = Coordinate A' (3, -3).

In conclusion, the coordinates of the image after a dilation by using a scale factor of 1/4 are (3, -3).

The vertex is (-2, 11), then the vertex form of the quadratic is:

f(x) = 5*(x + 2)^2 - 11

A quadratic equation with a leading coefficient a and a vertex (h, k) can be written in vertex form as:

y = a*(x - h)^2 + k

And for a quadratic equation of the form:

y = a*x^2 + b*x + c

The vertex is at:

h = -b/2a

In this case, our equation is:

f(x) =5x^2 + 20x + 9

Then:

h = -20/2*5 = -2

Evaluating in x = -2 we get:

f(-2) = 5*(-2)^2 + 20*-2 + 9

f(-2) = 5*4 - 40 + 9

f(-2) = 20 - 40 + 9 = -20 + 9 = -11

The vertex is (-2, -11), and the leadin coefficient is a = 5, then the vertex form is:

f(x) = 5*(x + 2)^2 - 11

Answer:

1/3

Explanation:

Imagine you repeat the experiment 100 times.

It is expected that half of the times (50) you take the fair coin and half of the times (50) the trick coin.

When you take the fair coin, half of the times you get heads, that is 25 times from 100 you “get the fair coin AND you get heads with the fair coin”.

When you take the trick coin, all the times you get heads, that is 50 times from the original 100 you “get the trick coin AND you get heads with the trick coin”.

In total, it is expected you get heads 75 times. And from those, 50 times will be with the trick coin and 25 times with the fair coin.

Now, if you get one of those at random, what’s the likelihood it was the fair coin?

Well, you have 25 cases it was the first coin and 50 cases it wasn’t, so it is 25 from a total of 75 and that is 25/75 = 1/3. That is, about 33.33%

Also, with probability theory:

Bayes’ Theorem:

P(B|A) = P(A ∩ B) / P(A)

P(A|B) = P(A ∩ B) / P(B)

So: with just the definitions I prove Bayes:

P(B|A) = P(A|B) * P(B) / P(A)

In our case:

P(Fair| Heads) = P(Heads|Fair) * P(Fair) / P(Heads)

p = P(Fair | Heads) = 0.5 * 0.5 / P(Heads)

What is P(Heads) ??

We can apply this:

Heads = (Heads ∩ Fair) U (Heads ∩ Trick)

And those in the union are disjoint (mutually exclusive), so:

P(Heads) = P(Heads ∩ Fair) + P(Heads ∩ Trick) =

= P(Heads|Fair) * P(Fair) + P(Heads|Trick) * P(Trick) =

= 0.5 * 0.5 + 1.0 * 0.5 = 1/4 + 1/2 = 3/4

Then:

p = P(Fair | Heads) = 0.5 * 0.5 / P(Heads) = 1/4 / (3/4) = 1/3

The probability that the sample proportion of the number of people using the courier will differ from the population proportion by greater than 0.03 is 0.0504

The probability is calculated using z score, this is used to determine the amount of standard deviations a sample, X is from the mean

The z score is given by the formula

z = (X - μ) / σ

Definition of variables

mean, μ  = p = 0.05

sample size, n = 202

standard deviation, σ

= √{(p(1 - p)) / n}

= √{(0.05(1 - 0.05)) / 202}

= √{(0.05 * 0.95) / 202}

= 0.01533

The probability

differ from the population proportion by less than 3%

|X - 0.05| > 0.03

X < 0.02 OR X > 0.08

P(z < 0.02) + P(z > 0.08 )

z score for z < 0.02

z = (0.02 - 0.05) / 0.01533

= -1.9569

p value for z < -1.9569 = 0.02518

z score for z > 0.08

z = (0.08 - 0.05) / 0.02196
