To add fractions with different denominators, we need to find a common denominator. By adding the fractions 1/2 and 7/8, we got the final answer is 11/8.

A fraction is part of a whole. In arithmetic, the number is expressed as a quotient, in which the numerator is divided by the denominator.

First, we can see that 3 and 8 have no common factors, so we can find their least common multiple (LCM), which is 24.

Then we can convert both fractions so that they have a denominator of 24:

1/3 = 8/24

4/8 = 3/6 = 12/24

Now we can add the fractions:

8/24 + 12/24 = 20/24

However, we should simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 4 in this case.

So the final answer is 5/6.

First, we can find the least common multiple (LCM) of the denominators, which is 8 in this case.

Then we can convert both fractions so that they have a denominator of 8:

1/2 = 4/8

7/8 = 7/8

Now we can add the fractions:

4/8 + 7/8 = 11/8

However, we should simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 1 in this case.

So the final answer is 11/8.

similarly,

3/4 + 2/3 = 17/12

7/16 + 9/16 = 1

1/6 + 4/9 = 11/18

1/2 + 1/6 = 2/3

3/10 + 1/2 = 4/5

4/15 + 1/3 = 3/5

3/4 + 7/12 = 4/3

5/6 + 3/10 = 17/15

The approximate of \(f_{x}(3,5)\) ≈ 4

We have to find an approximate of \(f_{x}(3,5)\)  using the contour diagram, x and y, which was shown below. The slope of a second line is used to estimate the x and y direction. The curl f divides by the curl x is almost equal to the delta x. At the point of x, 13 is equal to 17 and 2 is equal to 18. The points are in a diagram. The curly f divides by curly x is equal to the delta f divided by delta x, which is 18 minus 17 divided by 2 minus 1. The value of a f is equal to 1. From here we can say that f of x 13 is equal to 1.

The required probability is 0.325 or 32.5%.

Event A and B are independent. Suppose P(B) = 0.4 and P(A and B) = 0.13.

Given: P(B) = 0.4P(A and B) = 0.13

Formula used: We know that when two events A and B are independent, then P(A and B) = P(A) × P(B)

Hence, the formula for finding P(A) can be given by:P(A) = P(A and B) / P(B)

Now, let's put the given values in the formula:P(A) = 0.13 / 0.4P(A) = 0.325

So, the probability of event A is 0.325 or 32.5% (approx).

The equations given are x - 5y = 3 and 3x - 2y = -4. To find the solution to this system of equations, we need to find the values of x and y that satisfy both equations simultaneously.

One way to solve this system of equations is by substitution. We can solve one equation for x or y, and then substitute that expression into the other equation to eliminate one variable. Let's solve the first equation for x:

x - 5y = 3

x = 5y + 3

Now we can substitute this expression for x into the second equation:

3x - 2y = -4

3(5y + 3) - 2y = -4

15y + 9 - 2y = -4

13y = -13

y = -1

We can now substitute this value for y back into either equation to find the value of x:

x - 5y = 3

x - 5(-1) = 3

x + 5 = 3

x = -2

Therefore, the solution to the system of equations x - 5y = 3 and 3x - 2y = -4 is (-2, -1). This is the point where the solid line and dotted line intersect, as shown in the image.

The upper boundary of the first equation is at x = 12, y = 0. With these values, this is the second equation:

100(12) − 200(0) = 1,200.

The lower boundary of the first equation is at x = 0, y = 12. With these values, this is the second equation:

100(0) − 200(12) = -2,400.

Both of these scores are possible in the game, so they are both viable.

The x-component of fluid acceleration in terms of x and y is 2.

To find the x-component of fluid acceleration (ax), we need to differentiate the x-component of velocity (u) with respect to time.

However, the given equations provide the expressions for u in terms of x and y, not time. Therefore, we need to differentiate u with respect to x and y instead.

Given: u = 2x + y^2

To find the x-component of fluid acceleration (ax), we differentiate u with respect to x while treating y as a constant:

ax = ∂u/∂x = ∂(2x + y^2)/∂x = 2

The population proportion who participated in voting (63%) is higher than the sample proportion from this survey (58.91%).

To determine whether the population proportion who participated in voting or the sample proportion from the survey is higher, we need to compare the percentages.

The population proportion who participated in voting is given as 63% of all registered voters.

This means that out of every 100 registered voters, 63 participated in voting.

In the survey of retired voters, 162 out of 275 participants voted. To calculate the sample proportion, we divide the number of retired voters who participated (162) by the total number of retired voters in the sample (275) and multiply by 100 to get a percentage.

Sample proportion = (162 / 275) \(\times\) 100 ≈ 58.91%, .

Comparing the population proportion (63%) with the sample proportion (58.91%), we can see that the population proportion who participated in voting (63%) is higher than the sample proportion from this survey (58.91%).

Therefore, based on the given data, the population proportion who participated in voting is higher than the sample proportion from this survey.

The location of the test score associated with the third quartile is the value that corresponds to the 123rd rank in a class of 163 students.

The third quartile, also known as the upper quartile, is a statistical measure that divides a set of data into quarters. It is the point at which 75% of the data lies below it and 25% of the data lies above it. To find the location of the test score associated with the third quartile, we need to arrange the test scores in ascending order and then find the value that corresponds to the 75th percentile.

Given that there are 163 students in the class, we can determine the rank of the score associated with the third quartile as follows:

Rank of the third quartile = 0.75 x 163 = 122.25

Since we cannot have a fractional rank, we need to round up to the next whole number. Therefore, the rank of the score associated with the third quartile is 123.

Next, we need to find the value of the test score that corresponds to the 123rd rank. We can do this by using a percentile rank calculator or by manually counting the test scores from the lowest to the highest until we reach the 123rd score.

In summary, the location of the test score associated with the third quartile in a class of 163 students is the value that corresponds to the 123rd rank.

The range of the function g(x) = |x - 12| - 2 is {y | y > -2}, indicating that the function can take any value greater than -2.

To find the range of the function g(x) = |x - 12| - 2, we need to determine the set of all possible values that the function can take.

The absolute value function |x - 12| represents the distance between x and 12 on the number line. Since the absolute value always results in a non-negative value, the expression |x - 12| will always be greater than or equal to 0.

By subtracting 2 from |x - 12|, we shift the entire range downward by 2 units. This means that the minimum value of g(x) will be -2.

Therefore, the range of g(x) can be written as {y | y > -2}, which means that the function can take any value greater than -2. In other words, the range includes all real numbers greater than -2.

Visually, if we were to plot the graph of g(x), it would be a V-shaped graph with the vertex at (12, -2) and the arms extending upward infinitely. The function will never be less than -2 since we are subtracting 2 from the absolute value.

There's some unknown (but derivable) system of equations being modeled by the two lines in the given graph. (But we don't care what equations make up these lines.)

There's no solution to this particular system because the two lines are parallel.

How do we know they're parallel? Parallel lines have the same slope, and we can easily calculate the slope of these lines.

The line on the left passes through the points (-1, 0) and (0, -2), so it has slope

(-2 - 0)/(0 - (-1)) = -2/1 = -2

The line on the right passes through (0, 2) and (1, 0), so its slope is

(0 - 2)/(1 - 0) = -2/1 = -2

The slopes are equal, so the lines are parallel.

Why does this mean there is no solution? Graphically, a solution to the system is represented by an intersection of the lines. Parallel lines never intersect, so there is no solution.

Mary used 66 pounds of type A coffee and 82 pounds of type B coffee to make a total of 148 pounds of the blend, with a total cost of $694.20.

Let's assume Mary used x pounds of type A coffee and (148 - x) pounds of type B coffee.

The cost of type A coffee is $5.30 per pound, so the cost of the type A coffee used is 5.30x.

The cost of type B coffee is $4.20 per pound, so the cost of the type B coffee used is 4.20(148 - x).

According to the given information, the total cost of the blend is $694.20. Therefore, we can set up the equation:

5.30x + 4.20(148 - x) = 694.20

Simplifying and solving for x

5.30x + 621.60 - 4.20x = 694.20

1.10x = 72.60

x = 66

The statement is false. The existence of a scalar α such that αv is an eigenvector of a does not imply that v itself is an eigenvector of a.

A group of numbers built up in a rectangular array with rows and columns. The elements, or entries, of the matrix are the integers. In addition to numerous mathematical disciplines, matrices find extensive use in the fields of engineering, physics, economics, and statistics.

The statement is false. An eigenvector is a non-zero vector that, when multiplied by a matrix, produces a scalar multiple of itself. In other words, if v is an eigenvector of a matrix A, then Av = λv, where λ is the corresponding eigenvalue.

The statement suggests that if a is an nn matrix (presumably an n x n matrix), and a scalar α exists such that αv is an eigenvector of a, then v must also be an eigenvector of a. However, this is not necessarily true.

Let's consider a counterexample to demonstrate this. Suppose we have the 2x2 identity matrix I:

I = [[1, 0],

    [0, 1]]

In this case, any non-zero vector v will satisfy the condition αv = v for α = 1. However, not all non-zero vectors v are eigenvectors of I. In fact, the only eigenvectors of I are [1, 0] and [0, 1] with corresponding eigenvalues of 1.

Therefore, the statement is false. The existence of a scalar α such that αv is an eigenvector of a does not imply that v itself is an eigenvector of a.
