The set G = Zp × is a group under modular multiplication. This is because the set contains all the non-zero elements of Zp, and modular multiplication satisfies the four group properties:

Using Lagrange's Theorem, we can prove Fermat's Little Theorem: that for any integer a not divisible by p, ap-1 ≡ 1 (mod p). Let n be the smallest positive integer such that an ≡ 1 (mod p).

Since a is not divisible by p, the order of a (the smallest value of n) must divide p - 1, or in other words, n | (p - 1). By Lagrange's Theorem, this implies n = p - 1, which in turn implies that ap - 1 ≡ 1 (mod p). This proves Fermat's Little Theorem.

The measure of the vertex angle of triangle ACE is 50°. The solution has been obtained by using properties of angles.

What is an angle?

An angle is a figure in plane geometry that is created when two rays or lines share an endpoint.

We are given an isosceles triangle ACE which means that AC = CE.

We are given ∠BDE = 115°

Since, angles on a straight line form a linear pair, therefore

⇒∠BDE + ∠BDC = 180°

⇒115° + ∠BDC = 180°

⇒∠BDC = 65°

Since, BD║AE so,

∠BDC = ∠AEC

So, ∠AEC = 65°

Since, AC = CE so,

∠AEC = ∠CAE

So, ∠CAE = 65°

Now, using angle sum property, we get

⇒∠AEC + ∠CAE + ∠ACE = 180°

⇒65° + 65° + ∠ACE = 180°

⇒130° + ∠ACE = 180°

⇒∠ACE = 50°

Hence, the measure of the vertex angle of triangle ACE is 50°.

The formula for testing the significant difference between two population variances is the F-test. The F-test is used to compare the variances of two populations and is calculated by dividing the larger variance by the smaller variance. The formula for the F-test is:

F = s1^2 / s2^2

Where s1^2 is the variance of the first population and s2^2 is the variance of the second population.

If the calculated F value is greater than the critical F value from the F distribution table, then there is a significant difference between the two population variances. If the calculated F value is less than or equal to the critical F value, then there is not a significant difference between the two population variances.

If Angela used 1/5 of her beads and gave 78 to Santiago, she would have 130 beads left.

To find out how many beads Angela had left, we need to first find out how many beads she started with. We can do this by using the information given in the question and setting up an equation. Let's let x represent the number of beads Angela started with.

According to the question, Angela used (1)/(5) of her beads to make bracelets, so she had (4)/(5) of her beads left. She then gave 78 beads to Santiago, which left her with (1)/(2) of her original number of beads. We can write this as an equation:

(4)/(5)x - 78 = (1)/(2)x

To solve for x, we can first multiply both sides of the equation by 10 to get rid of the fractions:

8x - 780 = 5x

Next, we can subtract 5x from both sides of the equation to isolate the variable:

3x = 780

Finally, we can divide both sides of the equation by 3 to find the value of x:

x = 260

So Angela started with 260 beads. We proceed to find out how many you have left:

P = (1/2)(260)

P = 130

So Angela had 130 beads left after giving 78 beads to Santiago.

The Johnston index of each voter is 3.317 and the Deegan-Packel index of each voter is  0.154

The Johnston index and the Deegan-Packel index are two measures of voting power that take into account the number of votes each voter has and the number of votes required for passage.

a) The Johnston index is calculated by taking the square root of the product of the number of votes a voter has and the number of votes they need for passage. In this case, the Johnston index for each voter is:
MA: √(4*(12-4)) = √32 = 5.657
ME: √(3*(12-3)) = √27 = 5.196
NH: √(2*(12-2)) = √20 = 4.472
CT: √(4*(12-4)) = √32 = 5.657
RI: √(3*(12-3)) = √27 = 5.196
VT: √(1*(12-1)) = √11 = 3.317

b) The Deegan-Packel index is calculated by taking the number of winning coalitions that a voter is a part of and dividing it by the total number of winning coalitions. In this case, the Deegan-Packel index for each voter is:
MA: 20/26 = 0.769
ME: 14/26 = 0.538
NH: 8/26 = 0.308
CT: 20/26 = 0.769
RI: 14/26 = 0.538
VT: 4/26 = 0.154

Overall, the Johnston index and the Deegan-Packel index provide different perspectives on the voting power of each voter. The Johnston index takes into account the number of votes each voter has and the number of votes required for passage, while the Deegan-Packel index takes into account the number of winning coalitions each voter is a part of.

The least positive angle is 180 - θ.

To sketch the least positive angle and find the values of the six trigonometric functions for the given equation 3x + 5y = 0, x ≥ 0, we need to first find the slope and y-intercept of the equation.

The slope of the equation is -3/5 and the y-intercept is 0. This means that the line passes through the origin and has a negative slope.

To sketch the least positive angle, we need to find the angle between the x-axis and the line. Since the slope is negative, the angle will be in the second quadrant. The least positive angle is the reference angle in the second quadrant, which is 180 - θ.

To find the values of the six trigonometric functions, we can use the slope and y-intercept to find the coordinates of a point on the line. One such point is (5, -3).

Using these coordinates, we can find the values of the trigonometric functions:
sin θ = -3/√(5^2 + (-3)^2) = -3/√34
cos θ = 5/√(5^2 + (-3)^2) = 5/√34
tan θ = -3/5
csc θ = √34/-3
sec θ = √34/5
cot θ = -5/3

Therefore, the least positive angle is 180 - θ and the values of the six trigonometric functions are as follows:
sin θ = -3/√34
cos θ = 5/√34
tan θ = -3/5
csc θ = √34/-3

Answer:

118.7 inches squared.

Step-by-step explanation:

The area is the total space taken up by a flat (2-D) surface or shape. The area is always measured in square units.

Diameter is the length across the entire circle, the line splitting the circle into two identical semicircles.

The expression for solving the area of a circle is A = π × [tex]r^{2}[/tex].

To solve for the semicircle above, we can divide the diameter into 2 to get the radius.

So, the radius of the upper semicircle is 6 inches.

If the radius of a circle is 6 inches, then you can substitute r for 6 into the formula.

This simplifies to A = 36π. If a semicircle if half the size of a normal circle, then it will be A = 18π, because 36 ÷ 2 = 18.

To solve for the lower semicircle, we can do the same this as we did above.

But wait, we don't know the radius or diameter!

No worries! To solve for the diameter of the circle, we can take the line that is parallel to the semicircle (the one that has a length of 12in) and subtract 6 from it. We subtract 6 from it because the semicircle takes up the remaining length of the line, not including the 6in.

To solve for the lower semicircle, we can divide the diameter by 2 to get the radius.

So, the radius of the circle is 3.

Now we can insert 3 into the expression.

This simplifies to A = 9π. If a semicircle if half the size of a normal circle, then it will be A = 4.5π because like above, 9 ÷ 2 = 4.5.

Adding the two semicircles together:

So, the area of both semicircles is approximately 70.6858 square inches.

To solve for the area of a rectangle we use the expression:

Inserting the dimensions of the rectangle:

So, the area of the rectangle is 48 square inches.

Adding the two areas together:

Therefore, the area of the entire figure, rounded to the nearest tenth is [tex]118.7[/tex] [tex]in^{2}[/tex].

A. we can observe that 1(x) is continuous at x = kπ- for any integer k, and hence, it is continuous only at x = kπ, where k is an integer.

B. We have proved that limx → 2 (x2 - 1) = 3 using the definition of a limit.

A. To prove that 1(x) = {(sin(x) × EQ (x) XER-Q, X = zkπ, K 6 z is continuous only at x = kπ, where k is an integer without using L'Hospital's Rule, we can use the concept of limits.Let's consider the left limit of the function at x = kπ+ (where ε > 0 is a small value).

Here, we can observe that:

lim x → kπ+ 1(x) = lim x → kπ+ sin(x)/x > 0 since sin(x) > 0 when x is in (kπ, kπ + ε/2) and x is in (kπ - ε/2, kπ)

So, 1(x) = {(sin(x) × EQ (x) XER-Q, X = zkπ, K 6 z is continuous at x = kπ+ for any integer k.

Similarly, we can observe that 1(x) is continuous at x = kπ- for any integer k, and hence, it is continuous only at x = kπ, where k is an integer.

B. To prove that limx → 2 f(x) = 3, we can use the following definition of a limit:

For any ε > 0, there exists a δ > 0 such that |f(x) - 3| < ε for all 0 < |x - 2| < δ.

Here, f(x) = x2 - 1, and we need to prove that limx → 2 (x2 - 1) = 3.

Using algebraic manipulation, we can write x2 - 1 - 3 = (x + 2)(x - 2).Now, |(x + 2)(x - 2)| = |x + 2||x - 2|.

Therefore, we need to find δ such that |(x + 2)(x - 2)| < ε whenever 0 < |x - 2| < δ.

In order to ensure this, we can put an upper bound on |x + 2| and |x - 2|:|x + 2| < 4 (since x is close to 2)|x - 2| < δ

From the above inequalities, we can say that |(x + 2)(x - 2)| < 4δ.

Then, we can say that |(x2 - 1) - 3| = |(x + 2)(x - 2)| < 4δ < ε.

So, we can choose δ = ε/4.

Hence, we have proved that limx → 2 (x2 - 1) = 3 using the definition of a limit.

Box whisker plots are used to abstract a collection of data that has been approximated using an interval scale. Just a box plot is another name for it. They are mostly employed while interpreting data. It is one of the graphical approaches that shows how the dataset's data varies from one another. The histogram may be used to display the data as well. Yet a histogram offers a useful presentation. Box and whisker plots are preferable to histograms because they may exhibit numerous sets of data on a single graph, which adds more information.

From the box whisker plot we see that the lower quartile is 42 and the median is 56.

The median represents the 50th percentile whereas lower quartile is 75%.

The only possible rational zero of the polynomial is 0

The possible zeros of the polynomial P(v) = 14v^5 + 6v^4 + 5v^3 - 4v^2 + 2v can be found by using the Rational Root Theorem. This theorem states that if a polynomial has rational zeros, they will be in the form of p/q, where p is a factor of the constant term and q is a factor of the leading coefficient.

In this case, the constant term is 0 and the leading coefficient is 14. The factors of 0 are just 0, and the factors of 14 are 1, 2, 7, and 14. Therefore, the possible rational zeros of the polynomial are 0/1, 0/2, 0/7, and 0/14, which all simplify to just 0.

This means that the only possible rational zero of the polynomial is 0. However, there may also be irrational or complex zeros. To find these, we would need to use other methods, such as synthetic division or the quadratic formula.

In conclusion, the possible zeros of the polynomial P(v) = 14v^5 + 6v^4 + 5v^3 - 4v^2 + 2v are 0 and any irrational or complex numbers that satisfy the equation.
