how much would a school save by using company b instead of company a to server 200 students

Answer: c

Step-by-step explanation:

The correct answer is:

a = 43%

b = 88%

To determine the values of a and b in the relative frequency table, we need to analyze the information provided in the Venn diagram and the given table.

From the Venn diagram, we can gather the following information:

The circle labeled "satellite" has a value of 55.

The circle labeled "cable" has a value of 75.

The overlap between the two circles is labeled as 12.

Using this information, we can complete the table:

First column - "Satellite":

Entries: Satellite, Not satellite, Total

Total: 55 (as given in the Venn diagram)

Second column - "Cable":

Entries: Blank, 51%, Blank

To find the value for the "Cable" entry, we need to subtract the overlap (12) from the total number of cable users (75).

Cable: 75 - 12 = 63

Therefore, the entry becomes: Blank, 51%, Blank

Third column - "Not Cable":

Entries: a, b, Blank

To find the value for "a," we subtract the overlap (12) from the total number of satellite users (55).

a: 55 - 12 = 43

To find the value for "b," we subtract the overlap (12) from the total number of households (100).

b: 100 - 12 = 88

Therefore, the entries become: 43, 88, Blank

Fourth column - "Total":

Entries: Blank, Blank, 100%

The total number of households is given as 100% (as stated in the question).

Therefore, the values of a and b in the relative frequency table are:

a = 43% (rounded to the nearest percent)

b = 88% (rounded to the nearest percent)

Hence, the correct answer is:

a = 43%

b = 88%

Answer: 42 is the correct answer :]

The probability of the intersection of events A and B, P(AB), is 0.04.

When events A and B are independent, the probability of their intersection (AB) can be calculated by multiplying their individual probabilities.

Given that P(A) = 0.4 and P(B) = 0.1, we can find P(AB) as follows:

P(AB) = P(A) * P(B)

Substituting the given values:

P(AB) = 0.4 * 0.1

P(AB) = 0.04

Therefore , the probability of the intersection of events A and B, P(AB), is 0.04.

To understand the intuition behind this, let's consider two independent events, such as flipping a coin and rolling a die. The probability of getting heads on the coin is 0.5, and the probability of rolling a 4 on the die is 1/6. Since these events are independent, the probability of getting both heads on the coin and rolling a 4 on the die is calculated by multiplying their individual probabilities: 0.5 * 1/6 = 1/12. This means that the chance of both events occurring simultaneously is 1 out of 12 possibilities.

Similarly, in the given scenario, the probability of events A and B both occurring (P(AB)) is found by multiplying the probabilities of A and B: 0.4 * 0.1 = 0.04. This means that there is a 4% probability of both events A and B happening together.

The statements that can be used to compare the characteristics of the functions are:

1. g(x) has the greatest maximum value.

2. All three functions share the same domain.

Explanation:

- The table shows the values of three functions - f(x), g(x), and h(x) - evaluated at different values of x.

- We cannot determine the domain of f(x) or h(x) from the given table but we can see that g(x) has a domain of all real numbers.

- We can see that g(x) has the highest maximum value among the three functions, which is 8.

- We cannot determine the range of f(x) or g(x) from the given table but we can see that h(x) has a range of all negative numbers.

- We cannot say anything about the domain or range of f(x) based on the given table.

- Therefore, the two statements that can be used to compare the characteristics of the functions are: g(x) has the greatest maximum value and all three functions share the same domain.

Step-by-step explanation:

given two secants to a circle from an external point , then

the product of the measures of one secant's external part and that entire secant is equal to the product of the measures of the other secant's external part and that entire secant , that is

x(x + 21) = 10(10 + 17) ← distribute parenthesis

x² + 21x = 10 × 27 = 270 ( subtract 270 from both sides )

x² + 21x - 270 = 0 ← in standard form

(x + 30)(x - 9) = 0 ← in factored form

equate each factor to zero and solve for x

x + 30 = 0 ⇒ x = - 30

x - 9 = 0 ⇒ x = 9

however, x > 0 , then x = 9

a. The answer is: The fewest number of multibase blocks required to represent 20 longs in base seven is 2 flats.

b. The answer is: The fewest number of multibase blocks required to represent 10 longs in base three is 3 flats and 1 unit.

a. To represent 20 longs in base seven, we need to find the fewest number of multibase blocks required.

In base seven, we have the following conversions:

1 long = 1 unit

1 flat = 10 units

1 block = 10 flats

To represent 20 longs, we can use 2 flats (each flat representing 10 units) and 0 units since there are no remaining units.

So, the fewest number of multibase blocks required would be 2 flats.

Therefore, the answer is: The fewest number of multibase blocks required to represent 20 longs in base seven is 2 flats.

b. To represent 10 longs in base three, we need to find the fewest number of multibase blocks required.

In base three, we have the following conversions:

1 long = 1 unit

1 flat = 3 units

1 block = 3 flats

To represent 10 longs, we can use 3 flats (each flat representing 3 units) and 1 unit since there is one remaining unit.

So, the fewest number of multibase blocks required would be 3 flats and 1 unit.

Therefore, the answer is: The fewest number of multibase blocks required to represent 10 longs in base three is 3 flats and 1 unit.

The solution to the cube root equation ^3√(x + 1) - 2 = 0 is x = 7.

To solve the cube root equation ^3√(x + 1) - 2 = 0, you can follow these steps:

Isolate the cube root term: Add 2 to both sides of the equation, resulting in ^3√(x + 1) = 2.

Remove the cube root by raising both sides to the power of 3: Cubing both sides gives (^3√(x + 1))^3 = 2^3. This simplifies to x + 1 = 8.

Isolate the variable x: Subtract 1 from both sides of the equation, resulting in x = 8 - 1, which simplifies to x = 7.

In summary, to solve a cube root equation, you need to isolate the cube root term by performing inverse operations on the equation. In this case, adding 2 to both sides isolated the cube root term.

Then, you remove the cube root by raising both sides to the power of 3, which simplifies the equation to x + 1 = 8. Finally, by isolating the variable x, you subtract 1 from both sides to obtain the solution x = 7.

Therefore, using the midpoint rule with n = 4, the estimated work done by the force in moving the object from x = 2 to x = 18 is approximately 109.6 J.

To estimate the work done by the force in moving an object from x = 2 to x = 18 using the midpoint rule with n = 4, we divide the interval [2, 18] into 4 subintervals of equal width.

The width of each subinterval is given by Δx = (18 - 2) / 4 = 4.

Next, we calculate the midpoint of each subinterval and evaluate the force function at those midpoints.

The midpoints are: x = 4, 8, 12, 16.

Evaluating the force function at the midpoints, we get: f(4) = 5.6, f(8) = 8.8, f(12) = 8, f(16) = 5.

Now, we can calculate the work done in each subinterval by multiplying the force by the width of the subinterval:

W₁ = f(4) * Δx = 5.6 * 4 = 22.4 J

W₂ = f(8) * Δx = 8.8 * 4 = 35.2 J

W₃ = f(12) * Δx = 8 * 4 = 32 J

W₄ = f(16) * Δx = 5 * 4 = 20 J

Finally, we sum up the individual work values to get the total work done:

W = W₁ + W₂ + W₃ + W₄ = 22.4 + 35.2 + 32 + 20 = 109.6 J

Given statement solution is :- The present value of R13,000 per year invested for 8 years at 10% compound interest is approximately R69,776.60.

To calculate the present value of an investment with compound interest, we can use the formula for the present value of an annuity:

PV = A *[tex](1 - (1 + r)^(-n)) / r[/tex]

Where:

PV = Present value

A = Annual payment or cash flow

r = Interest rate per period

n = Number of periods

In this case, the annual payment (A) is R13,000, the interest rate (r) is 10% per year, and the investment is made for 8 years (n).

Using the formula and substituting the given values, we can calculate the present value:

PV = [tex]13000 * (1 - (1 + 0.10)^(-8)) / 0.10[/tex]

Calculating this expression:

PV = [tex]13000 * (1 - 1.10^(-8)) / 0.10[/tex]

= 13000 * (1 - 0.46318) / 0.10

= 13000 * 0.53682 / 0.10

= 6977.66 / 0.10

An order-preserving function is one where x < y implies f(x) < f(y). An isomorphism is a one-to-one order-preserving function between two partially ordered sets, while an automorphism is an isomorphism of a set to itself.

In the given excerpt, it explains the concepts of order-preserving functions, isomorphisms, and automorphisms in the context of partially ordered sets.

Order-Preserving Function:

A function f: P -> Q, where P and Q are partially ordered sets, is said to be order-preserving if for any elements x and y in P, if x < y, then f(x) < f(y). In other words, the function preserves the order relation between elements in P when mapped to elements in Q.

Increasing Function:

If P and Q are linearly ordered sets, then an order-preserving function is also referred to as an increasing function. It means that for any elements x and y in P, if x < y, then f(x) < f(y).

Isomorphism:

A one-to-one function f: P -> Q is called an isomorphism of P and Q if it satisfies two conditions:

a. f is order-preserving: For any elements x and y in P, if x < y, then f(x) < f(y).

b. f is onto (surjective): Every element in Q has a pre-image in P.

When an isomorphism exists between (P, <) and (Q, <), it means that the two partially ordered sets have a structure that is preserved under the isomorphism. In other words, they have the same ordering relationships.

Automorphism:

An automorphism of a partially ordered set (P, <) is an isomorphism from P to itself. It means that the function f: P -> P is both order-preserving and bijective (one-to-one and onto). Essentially, an automorphism preserves the structure and order relationships within the same partially ordered set.

These concepts are fundamental in understanding the relationships and mappings between partially ordered sets, particularly in terms of preserving order, finding correspondences, and exploring the symmetry within a set.

The fraction in its lowest terms for 7 1/2 percent is 3/40.

To express the mixed number 7 1/2 percent as a fraction in its lowest terms, we need to convert it to a fraction and simplify.

First, we convert the mixed number to an improper fraction:

7 1/2 percent = 7 1/2 / 100

To simplify this fraction, we find the least common multiple (LCM) of the denominator (2) and the percent denominator (100), which is 200.

Now, we can rewrite the fraction with the common denominator:

7 1/2 / 100 = (7 * 2 + 1) / 200 = 15/200

To simplify the fraction further, we can divide both the numerator and denominator by their greatest common divisor (GCD). In this case, the GCD of 15 and 200 is 5.

15/200 = (15 ÷ 5) / (200 ÷ 5) = 3/40

AE || CB is proved using alternate interior angles.

1.1 To calculate the size of the angles:

(a) Ô₁: Since D = 50° and AD is a chord, Ô₁ is the central angle of chord AD. According to the properties of a circle, the measure of a central angle is equal to twice the measure of the inscribed angle it intercepts. Therefore, Ô₁ = 2D = 2 * 50° = 100°.

(b) с Ê₁: Angle с Ê₁ is an inscribed angle that intercepts chord CB. According to the inscribed angle theorem, the measure of an inscribed angle is equal to half the measure of the intercepted arc. In this case, the intercepted arc is AD. Since Ô₁ = 100° and the intercepted arc AD is opposite to Ô₁, с Ê₁ = 180° - Ô₁ = 180° - 100° = 80°.

1.2 To prove that AE || CB:

To prove that AE || CB, we need to show that the corresponding angles are equal.

Let's consider angle AED and angle BDC. Both angles are inscribed angles that intercept the same arc AD. According to the inscribed angle theorem, the measure of an inscribed angle is equal to half the measure of the intercepted arc. Since angle AED and angle BDC intercept the same arc AD, they are equal: AED = BDC.

Additionally, angle AED and angle с Ê₁ are alternate interior angles formed by a transversal (AD) intersecting two parallel lines (AE and CB). According to the alternate interior angle theorem, when two parallel lines are intersected by a transversal, the alternate interior angles are congruent. Therefore, angle AED = с Ê₁.

Since angle AED = с Ê₁ and AED = BDC, we can conclude that с Ê₁ = BDC. This equality of corresponding angles proves that AE is parallel to CB, and thus, AE || CB.

5. The integral of [tex]\(\frac{1}{2+5x} dx\)[/tex] is [tex]\(\frac{\ln|2+5x|}{5} + C\)[/tex].

Step-by-step explanation:

Let's break down each integral:

1. Integral of [tex]\(\cos(x) e^{\sin(x)} dx\)[/tex]

  This is a case of a simple substitution. We can let [tex]\(u = \sin(x)\)[/tex], then [tex]\(du = \cos(x) dx\)[/tex]. Substituting these into the integral, we get [tex]\(\int e^u du\)[/tex], which is simply [tex]\(e^u + C\)[/tex]. Substituting back for [tex]\(u\)[/tex], we get [tex]\(e^{\sin(x)} + C\)[/tex].

2. Integral of [tex]\(\cos^2(x) dx\)[/tex]

  The double-angle formula is used here. We know that [tex]\(\cos^2(x) = \frac{1 + \cos(2x)}{2}\)[/tex]. Substituting this into the integral, we get [tex]\(\int \frac{1 + \cos(2x)}{2} dx\)[/tex], which can be separated into two simpler integrals: [tex]\(\frac{1}{2} \int dx + \frac{1}{2} \int \cos(2x) dx\)[/tex]. The integral of [tex]\(dx\) is \(x\)[/tex], and the integral of [tex]\(\cos(2x)\)[/tex] is [tex]\(\frac{1}{2}\sin(2x)\)[/tex]. So, the result is [tex]\(\frac{x}{2} + \frac{\sin(2x)}{4} + C\)[/tex].

3. Integral of \(\frac{\cos(\sqrt{x})}{\sqrt{x}} dx\)

  This is another case of simple substitution. We can let [tex]\(u = \sqrt{x}\)[/tex], then [tex]\(du = \frac{1}{2\sqrt{x}} dx\), or \(2 du = \frac{dx}{\sqrt{x}}\)[/tex]. Substituting these into the integral, we get [tex]\(2 \int \cos(u) du\), which is \(2\sin(u) + C\)[/tex]. Substituting back for [tex]\(u\)[/tex], we get [tex]\(2\sin(\sqrt{x}) + C\)[/tex].

4. Integral of [tex]\(\frac{1}{\sqrt[3]{1-7x}} dx\)[/tex]

  Here, we can let [tex]\(u = 1 - 7x\)[/tex], then [tex]\(du = -7 dx\)[/tex], or [tex]\(-\frac{1}{7} du = dx\)[/tex]. Substituting these into the integral, we get [tex]\(-\frac{1}{7} \int u^{-1/3} du\)[/tex], which is [tex]\(-\frac{3}{7}u^{2/3} + C\)[/tex]. Substituting back for [tex]\(u\)[/tex], we get [tex]\(-\frac{3(1 - 7x)^{2/3}}{14} + C\)[/tex].

5. Integral of [tex]\(\frac{1}{2+5x} dx\)[/tex]

  This is a standard form of integral that results in a natural logarithm. The integral of [tex]\(\frac{1}{a+bx} dx\)[/tex] is [tex]\(\frac{1}{b} \ln |a+bx| + C\)[/tex]. So, the result is [tex]\(\frac{\ln|2+5x|}{5} + C\)[/tex].
