The regression line is flat when there is no ability to predict whatsoever. The regression line is sloped at an angle when there is a relationship. The extent to which the regression line is sloped, however, represents the degree to which we are able to predict the y scores with the x scores

Consecutive numbers are numbers that follow each other in order, with a difference of 1 between each number.

The concept of consecutive numbers has been studied since ancient times, and has been used in various mathematical problems and puzzles.

Consecutive numbers are also commonly used in algebra, where they can be used to set up equations to solve problems. For example, if you are asked to find the sum of the first n consecutive numbers, you can set up the equation (n/2)(2a + (n-1)) = sum, where a is the first number and sum is the total sum of the consecutive numbers.

In geometry, consecutive numbers are used to define polygons, such as triangles, quadrilaterals, pentagons, and so on. For example, a triangle consists of three consecutive vertices on a plane, while a quadrilateral consists of four consecutive vertices.

The formula below is often used by project managers to compute, E, the estimated time to complete a job, where O is the shortest completion time, P is the longest completion time, and M is the most likely completion time P = 6E - O - 4M.

Given, that E is the estimated time to complete a job.

O is the shortest completion time.

P is the longest completion time.

And, M is the most likely completion time.

The equation given, E = (O + 4M + P)/6

By balancing the equation, multiplying both sides by 6 we get

or, 6E = O + 4M + P

Now, subtracting O + 4M from both sides, we get

P = 6E - O - 4M.

Therefore, we get P in terms of P = 6E - O - 4M.

The proportion of people who have visited a haunted house among those who like horror movies is 53. 42 %.

We can find the proportion of people who have visited a haunted house among those who like horror movies by dividing the number of people who like horror movies and have visited a haunted house by the total number of people who like horror movies :

The proportion is therefore:

= Number who have visited haunted house / Total number of people who like horror movies x 100 %

= 39 / 73 x 100 %

= 0. 5342 x 100 %

= 53. 42 %

Answer:  x = 9/5 or  \(1\frac{4}{5}\)

35 1/5 is the perimeter of the square and the triangle.

Step-by-step explanation:

The square has 4 sides, so the perimeter of the square is 4(x+3)

The triangle has 3 sides so the perimeter is 3(3x-1)

The perimeters are equal, so 4(x+3) = 3(3x-1)

Solve by distributing and then

4x +12 = 9x - 3  subtract 4x from both sides and add 3 to both sides

4x-4x +12 -3 = 9x-4x -3 +3  cancel the zero sums and combine similar terms.

9 = 5x  divide both sides by 5

x =  9/5

Check:  4(9/5 +3) = 3[3(9/5) -1]

36/5 + 3   = [3( 27/5  -1 ]   27/5 -3  -3 equivalent -15/5  27/5 -15/5 = 12/5

36/5 = 3(12/5)  = 36/5   TRUE!  simplify to mixed numbers

35 1/5 is the perimeter of the square and the triangle.

Answer:

120yd cube

Step-by-step explanation:

The measure of angle K and L in the first figure is ∠L = 23 degrees and ∠K = 157. Second figure, the measure of ∠K = ∠L = 70 degrees.

A polygon's interior angle is the angle created between its two adjacent sides. Alternately, we may state that the internal angle of a polygon refers to the angle measured at the interior portion of a polygon.

For figure 2 the two lines are parallel to each other, and the line that meets the parallel line at points at M and L are from two equal lines.

Hence, the angle suspended by both are equal, that is:

∠L = ∠M

∠L = 23 degrees.

Now, the ∠K and ∠J are created by two parallel lines; hence they are equal:

∠K = ∠J = x

The sum of interior angles of a quadrilateral is 360, so:

∠L + ∠M + ∠J + ∠K = 360

23 + 23 + x + x = 360

46 + 2x = 360

2x = 360 - 46

x = 157

Hence, the measure of angle K and L is 157 and 23 respectively.

For the second figure, the angle K and L are created by equal length of segments.

∠K = ∠L = x

The sum of interior angles of a quadrilateral is 360, so:

∠L + ∠M + ∠J + ∠K = 360

x + 90 + 130 + x = 360

2x + 220 = 360

2x= 360 - 220

x = 70

Hence, the angle of K and L is 70 degrees.

The height of the bridge is  442.23m.

In the question ,

it is given that

time taken(t) to reach the pebble from bridge to the water = 9.5 sec

the initial velocity(u) = 0    ....as the ball was at rest ,

the acceleration(a) is the gravity = 9.8 m/s

let s be the distance between bridge and water , which means the height of the bridge = h

Now by the second equation of motion , we have

h = u*t + (1/2)*a*t²

Substituting the values of u, a, t from above , we get

h = 0*9.5 + (1/2)*9.8*(9.5)²

h = 0 + (1/2)*9.8*90.25

h = 0 + 884.45/2

h = 884.45/2

h = 442.225

h ≅ 442.23

Therefore , if a pebble dropped from a bridge strikes the water exactly 9.5 sec then the height of the bridge is 442.23m .

The value of x in degrees will be 6° and 11° using properties of parallel lines.

They are typically equal-distance, parallel straight lines. The lines here are parallel. They never come together no matter how far you extend them in any one way.

Pairs of equal-sized angles that are both obtuse or acute and are generated on the same side of the transversal are known as corresponding angles. Each pair of comparable angles on the same side of the crossing transversal is equal to the other.

The alternative angle theorem states that alternate interior angles or alternate exterior angles that come from cutting two parallel lines are congruent.

In the above figure,

8x + 7 = 55

8x  = 55 - 7

x = 6

Measure of the angle will be 8 × 6 + 7 = 49

Axis of symmetry: x = 2

Vertex at: (2, -13)

y-intercept is (0, -5)

Step-by-step explanation:

The equation for the x-value of the vertex in a quadratic of the form:

\(y=ax^2+bx+c\)

is given by:

\(x_{vert}=-\frac{b}{2\,a}\)

which in our case gives:

\(x_{vert}=\frac{8}{2*2} =2\)

Then the equation for the axis of symmetry is given by:  x = 2

and the y of the vertex can be calculated as:

\(y_{vert}=2 (2)^2-8\,(2)-5=-13\)

Then the vertex is at the point: (2, -13)

And the y-intercept is found when x=0, that is:

y-intercept is (0, -5)
