Answer:Net one

Step-by-step explanation:

To type in the square root of 0.20 × 0.80 ÷ 200 on a calculator, first enter the numerator (0.20 × 0.80) and divide by the denominator (200).

Then, press the square root button to get the result.

It is important to follow the order of operations, also known as PEMDAS, which means to first calculate the multiplication and division before taking the square root.

The correct answer should be approximately 0.02.

The four consecutive even integers are 28, 30, 32 and 34.

Given that, four consecutive even integers.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let the four consecutive even integers are x+1, x+3, x+5 and x+7.

2 times the sum of the first and second is 14 more than 3 times the fourth, we get

2(x+1+x+3)=3(x+7)+14

⇒ 4x+8=3x+21+14

⇒ 4x+8=3x+35

⇒ 4x-3x=35-8

⇒ x=27

So, four consecutive even integers are 28, 30, 32 and 34

Therefore, the four consecutive even integers are 28, 30, 32 and 34.

Answer:

y = \(-\frac{1}{5}x\) - 3

OR

y = \(-\frac{x}{5}\) - 3

Step-by-step explanation:

x + 5y = -15

5y = -x - 15

y = \(-\frac{1}{5}x\) - 3

or

(it's the same thing)

y = \(-\frac{x}{5}\) - 3

They are the same because x by itself has an invisible 1 in front of it.

1x = x

\(-\frac{x}{5}\) = \(-\frac{1x}{5}\) = \(-\frac{1}{5}x\)

a) The center of G and determining the distinct conjugacy classes, we can calculate the class equation of the finite group G.

b) We have shown both implications: if a Sylow p-subgroup is normal, then it is unique, and if it is unique, then it is normal.

(a) Deriving the class equation of a finite group G involves partitioning the group into conjugacy classes. Conjugacy classes are sets of elements in the group that are related by conjugation, where two elements a and b are conjugate if there exists an element g in G such that b = gag^(-1).

To derive the class equation, we start by considering the group G and its conjugacy classes. Let [a] denote the conjugacy class containing the element a. The class equation is given by:

|G| = |Z(G)| + ∑ |[a]|

where |G| is the order of the group G, |Z(G)| is the order of the center of G (the set of elements that commute with all other elements in G), and the summation is taken over all distinct conjugacy classes [a].

The center of a group, Z(G), is the set of elements that commute with all other elements in G. It can be written as:

Z(G) = {z in G | gz = zg for all g in G}

The order of Z(G), denoted |Z(G)|, is the number of elements in the center of G.

The conjugacy classes [a] can be determined by finding representatives from each class. A representative of a conjugacy class is an element that cannot be written as a conjugate of any other element in the class. The number of distinct conjugacy classes is equal to the number of distinct representatives.

By finding the center of G and determining the distinct conjugacy classes, we can calculate the class equation of the finite group G.

(b) To prove that a Sylow p-subgroup of a finite group G is normal if and only if it is unique, we need to show two implications: if it is normal, then it is unique, and if it is unique, then it is normal.

If a Sylow p-subgroup is normal, then it is unique:

Assume that P is a normal Sylow p-subgroup of G. Let Q be another Sylow p-subgroup of G. Since P is normal, P is a subgroup of the normalizer of P in G, denoted N_G(P). Since Q is also a Sylow p-subgroup, Q is a subgroup of the normalizer of Q in G, denoted N_G(Q). Since the normalizer is a subgroup of G, we have P ⊆ N_G(P) ⊆ G and Q ⊆ N_G(Q) ⊆ G. Since P and Q are both Sylow p-subgroups, they have the same order, which implies |P| = |Q|. However, since P and Q are subgroups of G with the same order and P is normal, P = N_G(P) = Q. Hence, if a Sylow p-subgroup is normal, it is unique.

If a Sylow p-subgroup is unique, then it is normal:

Assume that P is a unique Sylow p-subgroup of G. Let Q be any Sylow p-subgroup of G. Since P is unique, P = Q. Therefore, P is equal to any Sylow p-subgroup of G, including Q. Hence, P is normal.

Therefore, we have shown both implications: if a Sylow p-subgroup is normal, then it is unique, and if it is unique, then it is normal.

Answer:

The fractions are not equivalent. If you cross multiply 65 x 2 = 130 and 4 x 13 = 52. 130 > 52. Set them as a proportion. \(\frac{65}{4} = \frac{13}{2}\)

The third-period class has a higher mean score than the first-period class, indicating that, on average, the students in the third-period class scored higher on the midterm than the students in the first-period class.

The larger standard deviation of the third-period class compared to the first-period class indicates that the scores in the third-period class were more spread out, or more variable, than the scores in the first-period class.

This could be due to a variety of factors, such as differences in the difficulty of the test or differences in the academic abilities of the students.

The minimum possible area of each square cardboard piece which is used to produce circular drink coasters is 72.25 in².

The equation of the circle is the equation which is used to represent the circle in the algebraic equation form with the value of center point in the coordinate plane and measure of radius.

The standard form of the equation of the circle can be given as,

\((x-h)^2+(y-k)^2=r^2\)

Here (h,k) is the center of the circle and (r) is the radius of the circle.

A company produces circular drink coasters. the equation which represents the size of a coaster is,

\(x^2+ y^2 = 18.0625\)

The units are in the inches. This equation can be written as,

\(x^2+ y^2 = \dfrac{289}{16}\\x^2+ y^2 =\left( \dfrac{17}{4}\right)^2\)

Compare it with the equation of the circle, we get,

\(h=0\\k=0\\r=\dfrac{17}{4}\rm\; in\)

The radius of the circular coaster is 17/4. The diameter of it is,

\(d=2\times\dfrac{17}{4}\\d=\dfrac{17}{2}\rm \; in\)

Now, each coaster is cut from a square piece of cardboard. The diameter of the circular coaster will be equal to the side of the square piece of cardboard.

\(a=d=\dfrac{17}{2}\rm\; in\)

The area of the square is the square of its side. Thus, the area of a square piece of cardboard is,

\(A=a^2\\A=\left(\dfrac{17}{2}\right)^2\\A=72.25\rm\; in^2\)

Thus, the minimum possible area of each square cardboard piece which is used to produce circular drink coasters is 72.25 in².
