The first system is inconsistent, the second system is consistent and dependent, and the third system is consistent and independent.

A system of equations can be classified as consistent, dependent, or inconsistent. A consistent system has at least one solution. A dependent system has infinitely many solutions, and an inconsistent system has no solution.

The first system of equations, y=-x+1 and y=-x, is inconsistent. This is because there is no value of x that can make both equations true at the same time. The graphs of these equations would be parallel lines that never intersect, meaning there is no solution.

The second system of equations, y=x+2 and y=x, is consistent and dependent. This is because there are infinitely many solutions that make both equations true. The graphs of these equations would be the same line, meaning every point on the line is a solution.

The third system of equations, y=x and y=2x, is consistent and independent. This is because there is only one solution that makes both equations true. The graphs of these equations would be two lines that intersect at one point, meaning there is only one solution.

In summary, the first system is inconsistent, the second system is consistent and dependent, and the third system is consistent and independent.

The mean number of days to fix defects is 3.2 days.

The random variable in this case is the number of days it takes to fix defects in a pair of eyeglasses. Therefore, the correct answer is:
rv X = the number of days to fix defects

The corresponding histogram for this frequency table would be right-skewed. This is because there is a higher probability of it taking fewer days to fix the defects, with the probability decreasing as the number of days increases.

To find the mean number of days to fix defects, we need to multiply each number of days by its corresponding probability and then sum the results. The formula for this is:

mean = ∑(x * P(x))

Where x is the number of days and P(x) is the probability of it taking that number of days.

Using the data from the table, we can calculate the mean as follows:

mean = (1 * 0.1) + (2 * 0.2) + (3 * 0.3) + (4 * 0.25) + (5 * 0.1) + (6 * 0.05)

mean = 0.1 + 0.4 + 0.9 + 1 + 0.5 + 0.3

To find out how many of each product Derrick can buy, we can use algebra. Let's call the number of headphones x and the number of cell phone cases y. We can set up an equation to represent the situation:

26x + 14y = 150

Now we can solve for one of the variables in terms of the other. Let's solve for y:

14y = 150 - 26x

y = (150 - 26x)/14

Now we can plug in different values for x and see what values of y will result in a total cost of at least $150. For example, if x = 1, then y = (150 - 26)/14 = 8.86. This means that Derrick could buy 1 pair of headphones and 8 cell phone cases for a total cost of $150.

Similarly, if x = 2, then y = (150 - 52)/14 = 7. This means that Derrick could buy 2 pairs of headphones and 7 cell phone cases for a total cost of $150.

We can continue plugging in different values for x until we find a combination of products that will cost at least $150. Alternatively, we could use a graphing calculator or an online graphing tool to graph the equation and find the intersection points with the line y = 150. These intersection points will represent the combinations of products that will cost at least $150.

The inequality that represents the set of solutions above the straight line is: x-3y<5

What is a linear inequality?

A linear inequality is an inequality in which one side is a linear expression in one or more variables, and the other side is a constant, or another linear expression. The solution set of a linear inequality is a region in the coordinate plane that satisfies the inequality.

Calculate the inequality to represent the set of solution by shaded region:

A linear inequality can be represented by a shaded region on the coordinate plane. The boundary of the region is a straight line, and the shaded region represents all the points in the plane that satisfy the inequality. In this case, the line that intersects the x-axis at (5,0) and the y-axis at (0, -5/3) represents the boundary of the region.

To find the inequality that represents the set of solutions above the line, we first need to find the equation of the line. We can use the point-slope form of the equation of a line, which relates the slope of the line and a point on the line to the equation of the line.

We know that the line passes through the points (5,0) and (0, -5/3), so we can calculate the slope of the line by using the formula:

m = (y2 - y1) / (x2 - x1)

where (x1, y1) and (x2, y2) are the two points through which the line passes.

m = (-5/3 - 0) / (0 - 5) = 1/3

Now we can use the point-slope form of the equation of the line to write the equation of the line:

y - y1 = m(x - x1)

where (x1, y1) is one of the two points through which the line passes.

Using the point (5,0) as (x1, y1), we get:

y - 0 = (1/3)(x - 5)

y = (1/3)x - 5/3

3y = x - 5

To represent the set of solutions above the line, we need to use the greater than symbol. So the inequality that represents the set of solutions above the straight line is:

The equation of the line through (3,5) and parallel to the line whose equation is ( y=-6x+4 ) is y = -6x + 23.

To find the equation of a line with the given properties, we need to use the concept of parallel lines and the point-slope form of a linear equation.

Parallel lines have the same slope, so the slope of the new line will be the same as the slope of the given line ( y=-6x+4 ), which is -6.

Next, we can use the point-slope form of a linear equation, which is (y - y1) = m(x - x1), where m is the slope and (x1, y1) is a point on the line. Plugging in the given point (3, 5) and the slope -6, we get:

y - 5 = -6(x - 3)

Simplifying the equation, we get:

y - 5 = -6x + 18

y = -6x + 23

Finally, we can write the equation in slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept. The equation of the new line is y = -6x + 23.

Therefore, the equation of the line through (3,5) and parallel to the line whose equation is ( y=-6x+4 ) is y = -6x + 23.

No paint job, no trims, no extra things on the car.

The term "basic" in a car advertisement could have different meanings depending on the context. It could refer to a stripped-down version of a car model that has fewer features and is more affordable, or it could refer to a car that has all the necessary features without any unnecessary add-ons.

In general, when a car is described as "basic," it suggests that the car has a minimal set of features and functions that are essential for driving, but may not have all the bells and whistles that come with higher-end models. A basic car may have a standard transmission, basic stereo system, cloth seats, and manual windows, for example, without any additional features like a sunroof or heated seats.

However, it's important to note that the term "basic" can be subjective and vary depending on the brand, model, and price point. What one person considers basic, another may see as luxurious. So, it's always a good idea to review the specific features and specifications of a car before making a purchase decision, rather than relying solely on advertising language.

There are 4 white marbles out of 4+10 = 14 total

4/14 = 2/7 is the probability of randomly picking a white marble.

(2/7)*(2/7) = 4/49 is the probability of picking two whites in a row, when the first marble is replaced.

Use a calculator to find that 4/49 = 0.0816 approximately.

That converts to 8.16% after moving the decimal point two spots to the right. This is equivalent to multiplying by 100.

Based on the given information, the sample space for the event can be represented using a tree diagram, where the first level consists of the three pants (black, blue, and tan) and the second level consists of the five shirts (white, black, green, blue, and red). Each branch represents a possible combination of a pair of pants and a shirt.

To find the total number of outcomes in the sample space, we can simply multiply the number of options for pants (3) by the number of options for shirts (5), giving us a total of 15 possible outcomes.

For Natalie selecting a pair of pants and shirt that are the same color, the favourable outcomes would be the combinations where the pants and shirt are either both black or both blue. These can be listed as:

Plugging in \( x = 1 \) gives us \[ -144 = (1+1)(1-4)(1^2 - 6(1) + 13) = (2)(-3)(8) = -48a \] Solving for \( a \) gives us \[ a = \frac{-144}{-48} = 3 \] So, the expression for \( f(x) \) is \[ f(x) = 3(x+1)(x-4)(x^2 - 6x + 13) \]

To find the expression for \( f(x) \), we need to use the fact that the zeros of a polynomial are the values of \( x \) that make the polynomial equal to zero. This means that if \( -1, 4, \) and \( 3+2i \) are zeros of \( f(x) \), then the factors of \( f(x) \) are \[ (x+1)(x-4)(x-(3+2i))(x-(3-2i)) \] Now, we can simplify the last two factors by multiplying them together: \[ (x-3-2i)(x-3+2i) = (x-3)^2 - (2i)^2 = x^2 - 6x + 9 - 4i^2 = x^2 - 6x + 9 + 4 = x^2 - 6x + 13 \] So, the expression for \( f(x) \) is \[ f(x) = (x+1)(x-4)(x^2 - 6x + 13) \] Now, we can use the fact that \( f(1) = -144 \) to find the value of the leading coefficient of \( f(x) \). Plugging in \( x = 1 \) gives us \[ -144 = (1+1)(1-4)(1^2 - 6(1) + 13) = (2)(-3)(8) = -48a \] Solving for \( a \) gives us \[ a = \frac{-144}{-48} = 3 \] So, the expression for \( f(x) \) is \[ f(x) = 3(x+1)(x-4)(x^2 - 6x + 13) \] This is the final answer.

(ii) The cost of planting grass in the remaining portion of the garden at the rate of Rs 40 per m² is (900 - 120x + 4x²) × 40

To find the area of the path and the remaining portion of the garden, we need to first find the dimensions of the inner square after the path has been constructed.

Let the width of the path be "x" meters. Then the dimensions of the inner square garden will be (30-2x) meters on each side.

(i) The area of the path can be found by subtracting the area of the inner square from the area of the outer square.

Area of outer square = 30 × 30 = 900 sq.m.

Area of inner square = (30-2x) × (30-2x) = 900 - 120x + 4x² sq.m.

Area of path = Area of outer square - Area of inner square

= 120x - 4x² sq.m.

(ii) The remaining portion of the garden is the area of the inner square.

Area of remaining portion = (30-2x) × (30-2x) sq.m.

= 900 - 120x + 4x² sq.m.

The cost of planting grass in the remaining portion of the garden at the rate of Rs 40 per m² can be found by multiplying the area of the remaining portion by the rate.
