In short form, the use of the term Enigmatologist is a general term for anyone who deals with any puzzle science, such as mathematics. However, the word occultism is a new coin coined nearly 30 years ago by the American Will Shortz, the only trained occultist in the world.

Answer:

\(\sf h(x) = y -4\)

Answer:

x = 5

Step-by-step explanation:

x is to x+5 what x-2 is 70 x+1

x/x+5 = x-2/x+1

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

x^2+x = x^2+ 5x - 2x - 10

x^2 - x^2 = -x + 5x - 2x - 10

10 = 2x

x = 5

Use the Pythagorean Theorm

a^2 + b^2 = c^2

6^2 + 11^2 = x^2

x^2 = 4356

x = 66

The probability of winning by picking the number 30 in roulette is 1/38.

In the game of roulette, the wheel consists of 38 spaces, with numbers 0 through 36 and an additional space marked 00. When you pick a specific number, such as 30, the probability of that number coming up on the wheel can be determined by calculating the ratio of favorable outcomes to the total number of possible outcomes.

In this case, there is only one favorable outcome, which is the ball landing on the number 30. The total number of possible outcomes is 38 since there are 37 numbered spaces (0 through 36) and one additional space for 00. Therefore, the probability of winning by picking the number 30 is 1 out of 38.

To put it simply, if you were to play roulette many times, you would expect the number 30 to come up approximately once every 38 spins on average. This probability remains the same for each individual spin, as each spin of the roulette wheel is an independent event.

To determine if the polynomial is even, odd, or neither, we substitute -x for x in the polynomial and simplify. -3(-x)² + 6(-x) = -3x² - 6x. Since the polynomial is not equal to its negation, it is neither even nor odd.

To write the equation of the line with an x-intercept at -6 and a y-intercept at 2, we can use the slope-intercept form of a line, y = mx + b, where m is the slope and b is the y-intercept.

In this case, the y-intercept is given as 2, so the equation becomes y = mx + 2. To find the slope, we can use the formula (y2 - y1) / (x2 - x1) with the given points (-6, 0) and (0, 2). We find that the slope is 1/3. Thus, the equation of the line is y = (1/3)x + 2.

For the polynomial f(x) = -3x² + 6x, the degree is 2 and the leading coefficient is -3. The end behavior of the graph is determined by the degree and leading coefficient. Since the leading coefficient is negative, the graph will be "downward" or "concave down" as x approaches positive or negative infinity.

To find the zeros, we set the polynomial equal to zero and solve for x. -3x² + 6x = 0. Factoring out x, we get x(-3x + 6) = 0. This gives us two solutions: x = 0 and x = 2.

The x-intercept is the point where the graph intersects the x-axis, and since it occurs when y = 0, we substitute y = 0 into the polynomial and solve for x. -3x² + 6x = 0. Factoring out x, we get x(-3x + 6) = 0. This gives us two x-intercepts: (0, 0) and (2, 0).

To determine if the polynomial is even, odd, or neither, we substitute -x for x in the polynomial and simplify. -3(-x)² + 6(-x) = -3x² - 6x. Since the polynomial is not equal to its negation, it is neither even nor odd.

The length of the side XY taken out by using trigonometric formulas is 12.208 cm.

Now we know that ΔWXY is a right-angled triangle. With ∠XWY = 90°

Hence we see that we can use the trigonometric formulas to find the length of XY

Since ∠YWX = 35° with XW being the corresponding side and XY being the hypotenuse we can use the formula

cosx = base/hypotenuse

Now using a scientific calculator we can calculate

cos35 to be 0.81915

or, base/hypotenuse = 0.81915

or, WX/XY = 0.81915

or, 10/XY = 0.81915

or, XY = 10/0.81915

The joint probability density function (pdf) of Y1, Y2, and Y3 is, f(y1, y2, y3) = (1/(y1*y3^2)) * e^(-(y3/(y1+y2)) - (y2/y1)) for y1 > 0, y2 > 0, y3 > 0, and 0 elsewhere.

To obtain this joint pdf, we apply the transformation technique to the random variables X1, X2, and X3. We define the transformation functions:

Y1 = g1(X1, X2) = X1/X2
Y2 = g2(X1, X2, X3) = X3/(X1+X2)
Y3 = g3(X1, X2) = X1+X2

Next, we calculate the Jacobian determinant of the transformation:

J = |∂(Y1, Y2, Y3)/∂(X1, X2, X3)| = |1/(X2^2)|

Now, we express X1, X2, and X3 in terms of Y1, Y2, and Y3:

X1 = Y1Y3/(1+Y1+Y2)
X2 = Y3/(1+Y1+Y2)
X3 = Y2Y3/(1+Y1+Y2)

Substituting these expressions and the Jacobian determinant into the joint pdf of X1, X2, and X3, which is e^(-(x1+x2+x3)), we obtain the joint pdf of Y1, Y2, and Y3 as mentioned above.

Regarding the independence of Y1, Y2, and Y3, we can determine it by checking if the joint pdf factors into the product of the marginal pdfs. In this case, if the joint pdf does not factorize, then Y1, Y2, and Y3 are not mutually independent.

The rhombus have the meeting of the side length CD to be equal to 15.

A rhombus is a two-dimensional geometric shape with four equal sides and four equal angles, but the angles are not necessarily 90 degrees. It is a type of parallelogram.

Since all the sides of the rhombus are equal, then;

AD = AB = CD

4x - 9 = 2x + 3 = CD

we can solve for x as follows:

4x - 9 = 2x + 3

4x - 2x = 9 + 3 {collect like terms}

2x = 12

x = 12/2 {divide through by 2}

x = 6

so;

AD = 4(6) - 9

AD = 15.

Therefore, the rhombus have the meeting of the side length CD to be equal to 15.

We can solve this equation using the distributive property. First, we will use the distributive property to multiply the 3y by 2.

The distributive property is a mathematical rule that allows you to multiply a single number by a group of numbers by multiplying the single number by each number in the group individually. This rule can be expressed in two ways. The first way is a(b + c) = ab + ac. The second way is a(b - c) = ab - ac.

This will give us 2x * 3y = 2(3y). Then, we will subtract 6 from both sides of the equation, which gives us 2x * 3y - 6 = 2(3y) - 6. We can then divide both sides of the equation by 6, which gives us 2x * 3y / 6 = 2(3y) / 6. Finally, we can divide both sides of the equation by 3y, which gives us 2x = -2. Therefore, the solution to 2x 3y = -6 is 2x = -2.

Answer:

n = 8 or n = −6

Explanation:

First, isolate the absolute value:

5 − |n − 1| = −2

7 − |n − 1| = 0

7 = |n − 1|

Then, split this into two equations, since the result of the absolute value could be positive or negative:

7 = n − 1                           7 = −(n − 1)

8 = n                                7 = −n + 1

(11)  40% of 70 is 28.

(12) 30 is 200% of 60.

What is percent?

A percentage in mathematics is a figure or ratio that is stated as a fraction of 100. The abbreviations "pct.", "pct.", and occasionally "pc" are also used to indicate it, while the percent symbol, "%," is most frequently employed. A % has no dimensions and no standard measurement.

(7) Suppose 55 is x%  of 100.

So,

55x/100 = 100

x/100 = 100/55

x = 1.8181 x 100

x = 181.81%

Therefore, 55 is 181.81% of 100.

(8) Suppose 22% of x is 24.2

So,

x(22)/100 = 24.2

x = 24.2 x 100/22

x = 110

Therefore, 22% of 110 is 24.2

(9) Suppose 19 is 50% of x.

So,

19 = 50(x)/100

x = 19 x 100/50

x = 38

Therefore, 19 is 50% of 38.

(10) Suppose 25 is 32% of x.

So,

25 = 32(x)/100

x = 25 x 100/32

x = 78.125

Therefore, 25 is 32% of 78.125

(11) Suppose 40% of x is 28

So,

40(x)/100 = 28

x = 28 x 100/40

x = 70

Therefore, 40% of 70 is 28.

(12) Suppose 30 is x% of 60

So,

30(x)/100 = 60

x = 60 x 100/30

x = 200

Therefore, 30 is 200% of 60.

Answer:

819

Step-by-step explanation:

We solve the above question using simple interest

The formula for the total amount in a bank amount when it earn simple interest annually is:

A = P(1 + rt)

When

P = Initial amount in the account = 780

r = Simple Interest rate = 2.5% = 0.025

t = 2 years

A = 780(1 + 0.025 × 2)

A = 780(1 + 0.050)

A = 780(1 .050)

A = 819.00

Answer: y = 1.73*x - 0.46

Step-by-step explanation:

For a linear equation of the form:

y = a*x + b

Where a is the slope and b is the y-intercept.

If we have an angle of A degrees with respect to the x-axis, the slope of the function can be calculated as:

Tan(A) = a.

in this case, we have we have an inclination of 30° to the positive x-axis (measured from the positive y-axis) and we know that the angle between the positive x-axis and the positive y-axis is 90°, then the angle measured from the positive axis will be such that:

A + 30° = 90

A = 90° - 30° = 60°

Then the slope is:

a = Tan(60°) = 1.73

Then we have the equation:

y = 1.73*x + b

And we know that this line passes through the point (2, 3) then we can replace x by 2 and y by 3 in the equation, and find the value of b.

3 = 1.73*2 + b

3 - 1.73*2 = b = -0.46

Then the equation is:

y = 1.73*x - 0.46
