Brent's weighted average is 81.6%.

The weighted average can be described as a calculation that takes into account the varying degrees of importance of the numbers in a data set.

To calculate Brent's weighted average, you need to multiply each of his test scores by the weight for tests (30%), his quiz scores by the weight for quizzes (50%), and his homework scores by the weight for homework (20%), and then add all of those values together.

So first, multiply Brent's average test score of 82% by the weight for tests, which is 30%. That gives you 82% × 30% = 82% × 0.3 = 24.6%.

Then, multiply Brent's average quiz score of 94% by the weight for quizzes, which is 50%. That gives you 94% × 50% = 94% × 0.5 = 47%.

Then, multiply Brent's average homework score of 50% by the weight for homework, which is 20%. That gives you 50% × 20% = 50% × 0.2 = 10%.

Finally, add all of those values together: 24.6% + 47% + 10% = 81.6%.

Hence, Brent's weighted average is 81.6%.

Answer:

I think that B is not a linear equation.

Step-by-step explanation:

Linear eqautions can not contain exponents in them. B has x to the power of 3 and y to the power of 2, ruling it out to be a linear equation.

The difference in the Social Security and Medicare taxes paid is 1767.5.

a. The Social Security tax s(x) for 1978 can be expressed as a piecewise function as follows:

s(x) = 0.0605*min(x,17700)

b. The Social Security tax s(x) for 1988 can be expressed as a piecewise function as follows:

s(x) = 0.0751*min(x,45000)

c. The difference in Social Security and Medicare taxes paid between 1978 and 1988 is calculated as follows:

Difference = 0.0751*min(50,000,45000) - 0.0605*min(50,000,17700)

Difference = 1767.5

This means that if a person earned $50,000 in 1978 and $50,000 in 1988, the difference in the Social Security and Medicare taxes paid is 1767.5. This is because in 1978 the maximum taxable income was $17,700 and the Social Security and Medicare rate was 6.05%, so the Social Security and Medicare taxes paid would be 0.0605*min(50,000,17700) = 1053.5. In 1988, the maximum taxable income was increased to $45,000 and the Social Security and Medicare rate was increased to 7.51%, so the Social Security and Medicare taxes paid would be 0.0751*min(50,000,45000) = 2821. The difference between these two amounts is 1767.5.

Answer: the answer is 489

The area of the triangle is approximately 36.83 square units.

To find the area of a triangle using calculus, we can use the formula:

A = (1/2) ∫(x2 - x1)dy

Where x1 and x2 are the x-coordinates of the vertices, and dy is the change in the y-coordinate.

First, we need to find the equations of the lines that make up the sides of the triangle. The line between (0,0) and (6,1) has the equation y = (1/6)x. The line between (6,1) and (3,7) has the equation y = -2x + 13. The line between (3,7) and (0,0) has the equation y = (7/3)x.

Now we can use the formula to find the area of the triangle. We'll integrate from y = 0 to y = 1 for the first side, from y = 1 to y = 7 for the second side, and from y = 7 to y = 0 for the third side:

A = (1/2) ∫(x2 - x1)dy

= (1/2) ∫[(6x - 0) - (0 - 0)]dy from y = 0 to y = 1

+ (1/2) ∫[(13 - 2x) - (6x - 0)]dy from y = 1 to y = 7

+ (1/2) ∫[(0 - 0) - (7x/3 - 0)]dy from y = 7 to y = 0

= (1/2) ∫6xdy from y = 0 to y = 1

+ (1/2) ∫(13 - 8x)dy from y = 1 to y = 7

+ (1/2) ∫(-7x/3)dy from y = 7 to y = 0

= (1/2) [(3 - 0) + (49 - 8) + (-49/3 - 0)]

= (1/2) [(3) + (41) + (-49/3)]

= (1/2) [(147/3) + (123/3) + (-49/3)]

= (1/2) [(221/3)]

= 36.83

So the area of the triangle is approximately 36.83 square units.

The statistical unit for John's study is A. the 35 countries. John is trying to estimate the average literacy rate across all countries, and he randomly selected 35 countries to research their literacy rates. The statistical unit in this case is the individual country, as each country's literacy rate is being used to calculate the average.

The statistical unit for John's study is A. the 35 countries. This is because John's study is based on a sample of 35 countries that he randomly selected. The sample is used to estimate the average literacy rate for all countries. The sample size of 35 countries is large enough to provide a representative sample of the population of countries. If John had selected only a few countries or individuals, his estimate of the average literacy rate would not have been reliable. However, by selecting a sample of 35 countries, John can make a more accurate estimation of the average literacy rate for all countries.

Answer:  Their monthly mortgage payment, including principal and interest is $806.27. As we can calculate this problem using formula:

EMI = [P x R x (1+R)^N] / [(1+R)^N-1],

Given:  Laura and Martin obtain a 25-y \in a r, $ 90,000 conventional mortgage at 10.0 % on a house selling for $ 120,000.

Let us calculate their monthly mortgage payment, including principal and interest:

Formula: EMI = [P x R x (1+R)^N] / [(1+R)^N-1],

where, P = Principal amount, R = Rate of interest, N = Number of months.

Let, the principal amount be P = $90,000

Rate of interest be R = 10% per annum

Tenure N = 25 years = 25 x 12 = 300 months

Therefore, the monthly interest rate = 10% / (12 months) = 0.1 / 12 = 0.0083333

Monthly payment = [90000 x 0.0083333 x (1+0.0083333)^300] / [(1+0.0083333)^300-1]= $ 806.27

Step-by-step explanation:

Since the slope is positive (3) in the equation y = 3x + 1, it means that the graph has a positive slope, meaning the line slopes up from left to right.

The y intercept is 1

the x intercept is:  

0 = 3x + 1

x = 1/3

Therefore, the graph of y = 3x + 1 lies in quadrants I, II and III.  Graph the equation to prove this.  

Using the Well-Ordering Principle (WOP), it can be proven that in every tournament with n players (where n is a natural number), there is at least one top player, defined as someone who either beats every other player or beats someone who beats the other player.

We will prove this statement by contradiction. Assume that there exists a tournament with n players where there is no top player. This means that for each player, there exists either another player who beats them or a chain of players such that each player beats the next one. Now, consider the set S of all players in this tournament. Since S is a non-empty set of natural numbers, it has a least element, let's say k.

Now, player k either beats every other player in the tournament, making them a top player, or there exists a player, let's say player m, who beats player k. In the latter case, we have a chain of players: k, m, p_1, p_2, ..., p_t, where p_1 beats p_2, p_2 beats p_3, and so on until p_t.

However, this contradicts the assumption that there is no top player, as either player k beats every other player (if m does not exist), or player m beats someone who beats the other player (if m exists). Hence, by contradiction, we have shown that in every tournament with n players, there is at least one top player.

To simplify the equations so that there would be no fractions, we

1. Multiply both sides by 8

2. Multiply both sides by 12

3. Multiply both sides by 10

4. Multiply both sides by 30

From the question, we are to determine what we could do first to each side of the equations so that there would be no fraction

1. (4x -4)/8 = (x +2)/4

Multiply both sides by the LCM of the denominators

The denominators are 8 and 4

The LCM of 8 and 4 is 8

Thus,

Multiply both sides by 8

8 × (4x -4)/8 = 8 × (x +2)/4

4x -4 = 2(x +2)

2. 3(4 - r)/6 = (4 + r) /4

Multiply both sides by the LCM of the denominators

The denominators are 6 and 4

The LCM of 6 and 4 is 12

Thus,

Multiply both sides by 12

12 × 3(4 - r)/6 = 12 × (4 + r) /4

2 × 3(4 - r) = 3(4 + r)

6(4 - r) = 3(4 + r)

3. (5q + 3)/10 = (q + 2)/5

Multiply both sides by the LCM of the denominators

The denominators are 10 and 5

The LCM of 10 and 5 is 10

Thus,

Multiply both sides by 10

10 × (5q + 3)/10 = 10 × (q + 2)/5

(5q + 3) = 2(q + 2)

4. 4(b - 7)/15 = (b + 3)/10

Multiply both sides by the LCM of the denominators

The denominators are 15 and 10

The LCM of 15 and 10 is 30

Thus,

Multiply both sides by 30

30 × 4(b - 7)/15 = 30 × (b + 3)/10

2 × 4(b - 7) = 3(b + 3)

8(b - 7) = 3(b + 3)

The equation of the line that is parallel to the given line and passes through the point (–2, 2) is: B. y = 1/5(x) + 12/5

In order to determine the equation of this line, we would first of all calculate its slope. Mathematically, the slope of any straight line can be calculated by using this formula;

\(Slope,\;m = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope\;,m = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}\)

By critically observing the graph of the line, we can logically deduce the following points:

Point (x, y) = (0, -3)

Point (x, y) = (-5, -4)

Substituting the given points into the formula, we have;

Slope = (-4 - (-3))/(-5 - 0)

Slope = (-4 + 3)/(-5)

Slope = -1/-5

Slope = 1/5

In Geometry, two (2) lines are parallel under the following conditions:

m₁ = m₂

Note: m represents the slope.

Mathematically, the point-slope form of a line is given by this equation:

y - y₁ = m(x - x₁)

Where:

At point (-2, 2), we have:

y - 2 = 1/5(x - (-2))

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

y - 2 = x/5 + 2/5
