Answer: 1.23

Step-by-step explanation: To find this answer, we need to move the decimal place. So, the 7 will move 1 place to the right of the 7, and then the decimal place will move to the right of the 8. So, now it should look like this:

[tex]\frac{08.61}{7}[/tex]

Then, divide using long division. You should get 1.23. To check, you can multiply 1.23 by 7, to get the dividend, 0.861. I hope this helped!

Since the points on this graph represent a relationship between x- and y-values, a statement about the relationship which is true include the following: A, it cannot be proportional because the straight line through the points does not go through the origin.

In Mathematics, the graph of any proportional relationship between two (2) variables is always characterized by a straight line with the data points starting from the origin (0, 0) and passes through other unique data points on the cartesian coordinate.

By critically observing the graph which shows a relationship between the x-values and y-values, we can logically deduce that it does not start from the origin (0, 0) and as such, it does not represent a proportional relationship.

In this context, we can reasonably infer and logically conclude that cost is not proportional to area in the situation represented by this graph.

Researchers frequently select a level of significance of 0.05. The reason for this is that if we chose a lower threshold of significance, we will have less room to reject the null hypothesis and so a higher likelihood of making a type 2 error.

On the other hand, if the degree of significance is higher, more type 1 errors are made, leading us to reject the hypothesis even though it is correct. Therefore, 0.05 is a balanced level that is neither significantly greater nor significantly smaller. The health care and nutrition-related industries are mostly included in some of the studies where we require a lower level of importance. This type of industry has a higher error rate, which causes more fatalities and negative side effects.

We can use a higher level of relevance in a variety of circumstances, such as the entertainment and marketing-related industries. The reason for this is that even if there are more potential for error, it won't harm the person; instead, it just affects the information, which we can assess using common sense.

Answer:

Step-by-step explanation

since they are complementary their angles should add up to 90.

18+(8x-28)=90

you solve from there

add common values

8x-10+90

add 10 to both sides

8x=100

divide by 8

x=12.5

The answer is:

Work/explanation:

Since we're given both angles, we can set up an equation and find x.

The sum of two complementary angles is 90°.

Now, set up the equation:

[tex]\sf{8x-28+18=90}[/tex]

[tex]\sf{8x-10=90}[/tex]

Add 10 on each side

[tex]\sf{8x=100}[/tex]

The numeric values of each function at x = 3 are given as follows:

f(3) = 50.

g(3) = 10.

The division is given as follows: f(3)/g(3) = 5.

The space of f(x)/g(x) is given as all genuine values with the exception of x = - 7, as the function g(x), which is the denominator of the division, expects a worth of 0 at x = - 7.

To track down the numeric worth of a function or of articulation, we supplant each example of the variable in the function or in the articulation with the worth at which we need to track down the numeric worth.

Subsequently, the numeric values are found to supplant the solitary example of x by 3 in each function, as follows:

f(3) = 5(3) + 35 = 15 + 35 = 50.

g(3) = 3 + 7 = 10.

Subsequently, the division is given as follows:

(f/g)(3) = f(3)/g(3) = 50/10 = 5.

The eigenvalues of the matrix are -1,1,3 and the corresponding eigenvectors are [-1,2,2], [1,-1,-1], [1,1,1] respectively.

The matrix is given as

2 1 -1

3 2 -3

3 1 -2

To find the eigenvalues and eigenvectors of a matrix A, we need to solve the following equation:

Av = λv

where v is the eigenvector and λ is the eigenvalue.

So, we have

(2 1 -1) (x) = λ (x)

(3 2 -3) (y) (y)

(3 1 -2) (z) (z)

We can find the eigenvalues by solving the characteristic equation which is det(A-λI) = 0.

The characteristic equation for the above matrix is

(2-λ)((-λ-2)(-λ+1) - 2) - 3(1)(-λ+1) + 3(1)(-λ-2) = 0

Solving the above equation we get λ = -1,1,3

Now we can find the eigenvectors for each eigenvalue.

For λ = -1

(2 1 -1) (x) = -1 (x)

(3 2 -3) (y) (y)

(3 1 -2) (z) (z)

Solving the above equation we get x = -1, y = 2 and z = 2. So the eigenvector is [-1,2,2].

For λ = 1

(2 1 -1) (x) = 1 (x)

(3 2 -3) (y) (y)

(3 1 -2) (z) (z)

Solving the above equation we get x = 1, y = -1 and z = -1. So the eigenvector is [1,-1,-1].

For λ = 3

(2 1 -1) (x) = 3 (x)

(3 2 -3) (y) (y)

(3 1 -2) (z) (z)

Solving the above equation we get x = 1, y = 1 and z = 1. So the eigenvector is [1,1,1].

The length of the midsegment of 28. is 17 units and 29. is 27 units.

A line drawn by joining the midpoints of any two of the triangle's sides is known as the midsegment. All three sides of a triangle can be divided in half, with the midpoint being the point that is equally spaced from either vertex, regardless of whether the triangle is a right triangle, isosceles triangle, or sometimes an equilateral triangle.

If the slope and sides are same then we can cut the midsegment ad paste it such that it becomes an rectangle.

28. Now the length of the rectangle = n + 12 + n + 12 = 4n + 6 + 2n - 2

⇒ 2n + 24 = 6n +4

⇒ 20 = 4n

⇒ n = 20/4

⇒ n = 5

Length of midsegment = 5 + 12

                                       =  17 units

29. Now the length of the rectangle = 2n+ 11 + 2n+ 11 = 5n - 2 + n + 8

⇒ 4n + 22 = 6n + 6

⇒ 16  = 2n

⇒ n = 16/2

⇒ n = 8

Length of midsegment = 2(8) + 11

                                       =  27 units

Answer:

5509 yes votes

Step-by-step explanation:

We will start by adding together our ratio, so we know how many voters there were in a total ratio, so we can divide our total number of people by it, and then multiply it by the number of people who said yes (7 people).

Our ratio was 7:4, so adding those two numbers together gives us 11. Then, dividing 8657 by 11 gives us:

8657 / 11 = 787

Now, we will multiply 787 by 7, since that was the number of people who said yes:

787 * 7 = 5509

So, there were 5509 yes votes.

The equation of the line passing through the points (0, 3) and (-5, 0) is y = -3/5 x + 3

The equation of a line in slope-intercept form is y = mx + b, where m is the slope of the line and b is the y-intercept.

Here,

To find the equation of the line passing through the points (0, 3) and (-5, 0), we can use the slope-intercept form and the slope formula:

m = (y2 - y1) / (x2 - x1) = (0 - 3) / (-5 - 0) = -3/5

where (x1, y1) = (0, 3) and (x2, y2) = (-5, 0) are the coordinates of the given points.

Now we can substitute the value of m and the coordinates of one of the points into the equation of the line to find the value of b:

y = mx + b

3 = (-3/5)*0 + b

b = 3

So the equation of the line passing through the points (0, 3) and (-5, 0) is:

y = -3/5 x + 3

We can also convert the equation to point-slope form as :

y - y1 = m(x - x1)

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

y - 3 = -3/5 x

y = -3/5 x + 3

Hence, the equation of the line passing through the points (0, 3) and (-5, 0) is y = -3/5 x + 3
