The line segment joining the points (1/2, -2) and (1, 1) cuts the line 3x + 4y = 7 at the point of intersection of the line defined by the points and the line 3x + 4y = 7.

To find the ratio of the line segment at this point of intersection, we first need to find the point of intersection. We can do this by solving the system of equations defined by the line 3x + 4y = 7 and the line defined by the points (1/2, -2) and (1, 1).

Once we have the point of intersection (x,y), we can use the following formula to find the ratio:

(x - 1/2) : (y + 2) = (x2 - x1) : (y2 - y1) = (x - x1) : (y - y1)

Where (x1, y1) and (x2, y2) are the coordinates of the two points defining the line segment

Answer:

It's 4

Step-by-step explanation:

Trust the math

Answer: 4

Step-by-step explanation:

With the pythagorean theorem, a²+b²=c².

C² is always the hypotenuse, which in this case is [tex]2\sqrt 5\\[/tex]. The length of the base, a², is 2, ad we don't know b so we'll substitute it as "x".
So...
(2)²+(x)²=[tex](2\sqrt{5} )^2[/tex].

Simplify to get 4+(x)²=([tex]2\sqrt{5} \\[/tex])².

Now, to write as a single radical, we need to square the two ("undoing" the square root). So, we get ([tex]\sqrt{4} *\sqrt{5\\[/tex] )², which is ([tex]\sqrt{20}[/tex])². Since we're squaring a square root, the square root almost "cancels out", leaving just the 20.

Now going back to our pythagorean theorem equation,

4+(x)²=20. Now we can subtract 4, getting (x)²=16. Hence, x= ± 4, and since a side can't be egative, it's just 4.

VERIFICATION: (4)²+(2)²=20, =16+4=20 ✓

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas. The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

Given, that each pair of wings is made with 3/4 yard of fabric. Since the fabric costs $8 per yard. Therefore:

1) 3/4 x $8 will give us the cost of the amount required for 3/4 yard of fabric.  3/4 x $8 = $6 each

2) Now, we are told that Mr. Townsend needs to make 13 pairs of butterfly wings and as such:

Amount needed to make 13 pairs is expressed as; 3/4 x $8 x 13 = $78

3) Treat 1 yard of fabric like the fraction 4/4.

Now, if this 1 fabric is equal to $8, then it means that 3/4 of the fabric will be $6. That is for one pair of butterfly wings, there's 13 of those so multiply $6 by 13.

This is easier  because we know how much 1 fabric costs, but we don't know what 3/4 of it does, so we treat 1 yard of fabric as the fraction 4/4.

A two-sample t-test is the inferential statistical test that would be best suitable to this situation.

The area of mathematics known as probability deals with numerical representations of how likely it is for an event to happen or for a claim to be true. A number between 0 and 1 is the probability of an occurrence, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

A t-test is a method for evaluating hypotheses that involve examining the means of one or more populations. A t-test can be used to determine if one group deviates from a predetermined value, whether two groups diverge from one another (an independent two-sample t-test), or whether paired measurements reveal a statistically significant difference.

The sample variance is the most accurate point estimate of the population variance sigmasquared.

The best point estimate of the population variance is the sample variance. This is because the sample variance is an unbiased estimator of the population variance, meaning that it is the most accurate estimate of the population variance. The sample variance is calculated by taking each individual data point, subtracting the sample mean, squaring the result, and then summing the results. The sample variance then is the sum of these squared differences divided by the number of data points minus one. This is a consistent estimator, meaning that it will always produce the same result even if the sample size is different. This is why the sample variance is the best point estimate for the population variance.

a) An equation that relates the area of the desktop components is w(w+3) = w(7-w).

b) The value of w is 2.

c) The combined area of the desktop components is 20 square feet.

What is an area of an object?

The total space occupied by a flat (2-D) surface or the shape of an object is defined as its area. Draw a square on a piece of paper with a pencil. It is a two-dimensional figure. The area of the shape on the paper is referred to as its Area. Consider your square to be made up of smaller unit squares.

Given that two components joined together to make the desktop.

The width of both components is w ft.

The length of one component is 3+w ft.

The length of the other component is (7-w) ft.

The area of the first component is w(3+w) sq. ft.

The area of the second component is w(7-w) sq. ft.

The area of the components are equal.

Therefore,

w(3+w) = w(7-w)

3w + w² = 7w - w²

3w + w² - 7w + w² = 0

2w² - 4w = 0

2w(w - 2) = 0

Either                         or,

2w = 0                            w - 2 = 0

w = 0                                w = 2

Since the length of width is never zero, Thus w = 2.

The area of the component is w(3+w) +  w(7-w)  sq. ft

Putting w=2 in w(3+w) +  w(7-w)  sq. ft:

A = 2(3+2) +  2(7-2)  sq. ft

A = 10 +10  sq. ft

A = 20  sq. ft

An equation of the line of best fit in slope-intercept form include the following: y = -10x + 105.

If the trend continues, the number of pairs of shoes that would be left in stock 10 days after the shipment arrived is 5 pairs of shoes.

In order to write an equation of the line of best fit in slope-intercept form, we would use the given data points. Mathematically, the slope-intercept form of a line can be calculated by using this equation:

y = mx + c

Where:

Next, we would determine the slope by using the given data points as follows;

Slope, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope, m = (y₂ - y₁)/(x₂ - x₁)

Slope, m = (45 - 95)/(6 - 1)

Slope, m = -50/5

Slope, m = -10.

At point (1, 95), an equation of this line can be calculated in slope-intercept form as follows:

y - y₁ = m(x - x₁)

y - 95 = -10(x - 1)

y - 95 = -10x + 10

y = -10x + 10 + 95

y = -10x + 105

For the number of pair shoes left in stock 10 days, we have:

y = -10(10) + 105

y = -100 + 105

y = 5 pairs of shoes.

Graphing, Substitution, and Elimination.

Step-by-step explanation:

Graphing: Graphing is the best method to use when introducing a new student to solving systems of two equations in two variables because it gives them a visual to recognize what they are looking for. Graphing is less exact and often takes more time than the other methods. I only recommend graphing to find a solution if the problem comes with a graph already drawn and the intersection appears to be on an exact coordinate.

Substitution: Substitution gives the advantage of having an equation already written for the second variable when you find the first one. Substitution is best used when one (or both) of the equations is already solved for one of the variables. It also works well if one of the variables has a coefficient of 1.

Elimination: Elimination is the method that I use almost every time. If you are not sure which method to use, I recommend that you use elimination. Elimination is best used when both equations are in standard form (Ax + By = C). Elimination is also the best method to use if all of the variables have a coefficient other than 1.

I hope this gives you some idea about which method you should use. All three methods will give the same solution. Also, you should always check your answer in both equations to make sure it is correct.
