Answer:

Step-by-step explanation:

The solution to the set of equations can be found by solving the system:

3x + 3y = 12

x + y = 4

We can simplify the second equation by solving for y:

y = 4 - x

Substituting this expression for y into the first equation, we get:

The solution to the set of equations can be found by solving the system:

3x + 3y = 12

x + y = 4

We can simplify the second equation by solving for y:

y = 4 - x

Substituting this expression for y into the first equation, we get:

3x + 3(4 - x) = 12

3x + 12 - 3x = 12

12 = 12

This is a true statement, which means that the system is consistent and has infinitely many solutions. Therefore, the correct answer is:

There are infinitely many solutions.

Then , the lines are coincident and there are infinitely many solutions .

Case 2 :-

If we have,

[tex]\longrightarrow \boxed{ \dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}\neq\dfrac{c_1}{c_2} } \\[/tex]

Then, the linear equations are inconsistent and have no solutions , thus the lines are parallel .

So here with respect to angle standard form of pair linear equations, we have;

Hence here we have,

[tex]\longrightarrow \dfrac{a_1}{a_2} = \dfrac{3}{1} \\[/tex]

[tex]\longrightarrow \dfrac{b_1}{b_2}=\dfrac{3}{1} \\[/tex]

[tex]\longrightarrow \dfrac{c_1}{c_2}=\dfrac{-12}{-4}=\dfrac{3}{1} \\[/tex]

Answer: 165 degrees

Step-by-step explanation:

Let's start off and name the angle between the hour and minute hand x, representing the number of degrees between the hands. Next, let's look at the minute hand first. After exactly an hour, the minute hand does not change its position(since after one hour, it comes back to where it was previously). As for the hour hand however, its position differs by exactly "1 hour tick", which is equivalent to 30 degrees (360 / 12 hours). What that implies is that x would have to equal x + 30, which is clearly impossible. However, we can think about the problem in a different way: by looking at the acute angle only between the hands, that would indeed be possible. Assuming that x + 30 is greater than 180(since if it wasn't, that wouldn't be possible), we can write the following equation:

x = 360 - (x+30)

, with the right hand side coming from the fact that the obtuse angle of x + 30 must have an acute counterpart, of which both add up to 360.

Then, we can simplify to:

x = 330 - x

or:

2x = 330

x = 165.

This gives us our only answer of 165 degrees

Answer:

To find the slope of a line parallel to 3x - y = -1, we need to first rearrange this equation into slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept. Starting with 3x - y = -1, we can add y to both sides to get: 3x = y - 1 Then, we can add 1 to both sides to get: 3x + 1 = y This is now in slope-intercept form, with y = 3x + 1, so we can see that the slope of the line is 3. Since we want to find the slope of a line parallel to this one, we know that it must have the same slope of 3. Therefore, the answer is: Slope = 3.

So, the corresponding point for g(x) on the graph of f(x) is (-3/2, F (-3/2)).

In mathematics, a function is a relation between a set of inputs (the function's domain) and a set of possible outputs (the function's range) with the property that each input is associated with exactly one output.

Functions are often described using a formula or an equation, such as [tex]f(x) = x^2,[/tex] where "f" is the name of the function, "x" is the input variable, and "[tex]x^2[/tex]" is the output. The value of the function for a specific input value of "x" can be found by substituting that value into the equation.

Functions are used in many areas of mathematics, science, engineering, and economics to model real-world phenomena, analyze data, and solve problems. They are also important in computer science, where they are used to write algorithms and design software.

if we know the point (x, y) on the graph of a function f(x), we can find the corresponding point for the function g(x) = F(-1/2x) by substituting -1/2x for x in the expression for f(x) and simplifying. That is, we can find the point (u, v) on the graph of g(x) such that u = -1/2x and v = F(-1/2x), where (x, y) is a point on the graph of f(x).

For example, if f(x) = x^2 and the point (3, 9) is on the graph of f(x), then we can find the corresponding point for g(x) = F(-1/2x) by substituting -1/2x for x in the expression for f(x) and simplifying:

Answer:

Leonhard Euler was a Swiss mathematician who lived from 1707-1783. He made significant contributions to many areas of mathematics, including number theory, calculus, and geometry.

One of Euler's significant contributions to the field of sequences and series is his work on the summation of infinite series. In particular, he developed a method for finding the sum of an infinite geometric series, which has the form:

a + ar + ar^2 + ar^3 + ...

where a is the first term, r is the common ratio, and the series continues infinitely.

Euler's method for finding the sum of this series is as follows:

If |r| < 1, then the sum of the series is:

a / (1 - r)

For example, let's consider the infinite geometric series:

2 + 4 + 8 + 16 + ...

In this series, a = 2 and r = 2. Since |r| < 1, we can use Euler's formula to find the sum:

sum = a / (1 - r)

= 2 / (1 - 2)

= -2

Therefore, the sum of the infinite geometric series 2 + 4 + 8 + 16 + ... is -2.

Euler's formula is just one example of his many contributions to mathematics. His work on sequences and series laid the foundation for many important concepts in calculus, and his ideas continue to influence the field of mathematics today.

n = number of samples

From the information given,

µ = 46 days

Answer: To find the margin of error and construct a 90% confidence interval for the population mean, we can use the following formula:

Margin of error = t-value x (standard deviation / square root of sample size)

where t-value is the value obtained from the t-distribution table with n-1 degrees of freedom and a confidence level of 90%.

For a sample size of 8 and a confidence level of 90%, the degrees of freedom is 7 and the t-value is 1.895 (obtained from a t-distribution table).

Using the given values, we can calculate the margin of error as:

Margin of error = 1.895 x (7.9 / sqrt(8)) ≈ 5.69 (rounded to one decimal place)

So the margin of error is approximately 5.69 miles.

To construct a 90% confidence interval for the population mean, we can use the formula:

Confidence interval = sample mean ± margin of error

Substituting the values, we get:

Confidence interval = 18.5 ± 5.69

So the 90% confidence interval for the population mean is (12.81, 24.19).

Interpretation:

We are 90% confident that the true mean driving distance to work for the population lies between 12.81 and 24.19 miles. This means that if we were to take many samples of 8 people and calculate the confidence interval for each sample, 90% of those intervals would contain the true population mean. The margin of error is the amount by which the sample mean may differ from the true population mean.

As a result, the range of the population's mean height for male Swedes is between 70.331 and 73.669 inches.

The range of a function or relation in mathematics is the collection of all feasible output values (also known as the dependent variable). It is the collection of all possible values that such a function can have. For instance, since its function can output anything non-negative real integer, f(x) = x2 would have a range of all non-negative real numbers. The range is frequently stated as a collection of numbers or as a circle, and it may be either finite or infinite.

given

For the population mean height of male Swedes, the following formula provides a 95% confidence interval:

where n is the sample size, x is the sample mean, y is the standard deviation of height, n* is the z-score corresponding to a 95% confidence level, which is 1.96, and z* is the z-score.

By entering the specified values, we obtain:

CI = 72 ± 1.96 * (3/√48)

CI = (70.331, 73.669) (70.331, 73.669)

As a result, the range of the population's mean height for male Swedes is between 70.331 and 73.669 inches.

By multiplying the critical value (1.96), by the standard error, one may determine the error bound:

EBM = 1.96 * (3/√48) ≈ 1.382
