Answer: 7/13 is the y intercept

Answer:

x = 20

Step-by-step explanation:

x + 2x + 6x = 9x / 180

x=20

triangles = 180

angle 1 = ?

angle 2 = 160?

angle 3 = 20

1. Reason: Since QA divides ∠PQR into two different parts so it is a bisector∠PQA≅∠RQA.

2. The line which divides an angle into two different angles is known as a bisector.

4. ∠QXA≅∠QYA and they are situated opposites to each other so we can say that right angles are conjugate.

The value of x in quadrilateral JKLM is 29

A quadrilateral is a closed shape and a type of polygon that has four sides, four vertices and four angles. It is formed by joining four non-collinear points. The sum of interior angles of quadrilaterals is always equal to 360 degrees.

The sum of the interior angles in a quadrilateral is 360°

∠J + ∠K + ∠L + ∠M = 360

3X + 90 + 2X + 8 + 4X + 1 = 360

9x + 99 = 360

9x = 360 - 99

9x = 261

x = 261/9

x = 29

In conclusion 29 is the value of x in the quadrilateral.

Answer:

The runners will be in a straight line after 1/2 seconds.

To solve this problem, we can set the y-coordinates of each runner equal to each other and solve for t. The y-coordinate represents the lane number, and if the lane numbers are equal, the runners are on a straight line.

Jon: y = 1

Laura: y = 2

Ellis: y = 4

Jon: 3t = 1

Laura: 4t = 2

Ellis: 6t = 4

Solving these equations simultaneously, we find that t = 1/2 seconds. This means that after 1/2 seconds, the runners will be in a straight line.

For 8% p-value cutoff , Melissa should use 92% confidence interval

A confidence interval calculated for a treatment effect measure shows the range in which the true treatment effect is likely to fall.

A smaller sample size or higher variability will result in a wider confidence interval with a larger margin of error. The interval width is also influenced by the level of confidence. If you want a higher level of certainty, the interval should be wider.

The width of the confidence interval and the size of the p value are related.

The narrower the interval, the smaller the p value. The confidence interval, on the other hand, provides useful information about the likely magnitude of the effect under consideration as well as the accuracy of the estimate.

The solution of the equations 4x + 6y = 21 and 7x - 3y = 3 will be (1.5, 2.5).

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The linear equation is given below.

4x + 6y = 21            ...1

7x - 3y = 3              ...2

From equation 2, then we have

7x - 3y = 3

3y = 7x - 3

y = (7/3)x - 1

Put in equation 1, then we have

4x + 6[(7/3)x - 1] = 21

4x + 14x - 6 =  21

18x = 27

x = 3/2

x = 1.5

Then the value of the variable 'y' is calculated as,

y = (7/3)(3/2) - 1

y = 7/2 - 1

y = 3.5 - 1

y = 2.5

The solution of the equations 4x + 6y = 21 and 7x - 3y = 3 will be (1.5, 2.5).

The data given from the graph proves that Catherine and Ana's suspicions were correct and the athletes at their school do indeed have a quicker reaction time than other students at their school. The average reaction time for the athletes ranges from 240 - 300, while the normal student's reaction time ranges from 260 - 330. There still should be more experiments to test this theory to get more detailed and accurate results because there are still athletes that have the same reaction time as normal students and the dot away from the boxes shows that there is a athlete that has a slower reaction rate than all of the  normal students. So it is safe to say there is indeed a difference in reaction times, but not a drastic one.

According to the given statement Liam is incorrect because average speed is 34.28 miles per hour.

The average scores of a body's speed over a duration of time is its average speed. Because a moving body's speed is not constant over time and fluctuates, the average speed formula is required.

The overall distance the thing travels in a given amount of time is its average speed. A scalar value symbolizes the average speed. It has no direction and therefore is indicated by the magnitude.

Distance covered in first three hours = 40 × 3 = 120 miles

Time taking to covered remaining 120 miles = 120/30

                                                                          = 4 hours

Total time = 4 hours + 3 hours = 7 hours

Total distance = 120 miles + 120 miles

                        = 240 miles

Average speed = total distance /  total time

Average speed = 240 miles / 7 hours = 34.28 miles per hour

Any quality that pertains to a certain set is referred to in mathematics as a property. A property p that is rigorously specified for every component of a set X is typically defined as a function p: X → {true, false}.

The four properties of equality addition, subtraction, multiplication, and division can be used to solve an equation. To get the value of an equation's unknown variable, we can easily add, subtract, multiply, or divide the two sides of the equation.

The qualities of equality are those characteristics that have no effect on an equation's truth value, i.e., those characteristics that do not affect the equality of two or more values. These equality-related qualities enable us to define an equivalence relation and solve a number of algebraic equations.

y = [tex]\frac{2}{3}[/tex] x + [tex]\frac{26}{3}[/tex]

y = [tex]\frac{-3}{2}[/tex] x

Step-by-step explanation:

y = [tex]\frac{-3}{2}[/tex] x - 6

The slope of this line is -3/2

A perpendicular slope is the opposite reciprocal.  That means you flip it upside down and take the opposite sign.  Since this slope is negative, the perpendicular slope will be positive.  If I turn this fraction upside down it will be 2/3, so the perpendicular slope is 2/3.

For the equation of the line we need the slope (m) and the y intercept.  To find that we will use the point that goes through this line.

m = (2/3)

x  = -4      from the point given (-4, 6)

y = 6        from the point given (-4,6)

y = mx + b

6 = [tex]\frac{2}{3}[/tex] [tex](\frac{-4}{1})[/tex] + b

6 = [tex]\frac{-8}{3}[/tex] + b   Add [tex]\frac{8}{3}[/tex] to both sides

[tex]\frac{6}{1}[/tex] + [tex]\frac{8}{3}[/tex] = b

[tex]\frac{18}{3}[/tex] + [tex]\frac{8}{3}[/tex] = b

[tex]\frac{26}{3}[/tex]

y = [tex]\frac{2}{3}[/tex] x + [tex]\frac{26}{3}[/tex]

Parallel lines have the same slope.

m = [tex]\frac{-3}{2}[/tex]

x = -4   from the point (-4,6)

y = 6   from the point (-4,6)

y = mx + b

6 = [tex]\frac{-3}{2}[/tex][tex](\frac{-4}{1})[/tex] + b

6 = 6 + b  Subtract 6 from both sides

0 = b

y = [tex]\frac{-3}{2}[/tex] x

The correlation coefficient is -7.44, which shows a strong negative correlation.

To calculate the correlation coefficient, you can use the following formula:

r = (n Σ(xy) - Σ(x) Σ(y)) / √((n Σ(x²) - (Σ(x))²) (n Σ(y²) - (Σ(y))²))

Where n is the number of data points, x is the variable on the x-axis, y is the variable on the y-axis, Σ(xy) is the sum of the products of x and y, Σ(x) is the sum of x, Σ(y) is the sum of y, Σ(x²) is the sum of the squares of x, and Σ(y²) is the sum of the squares of y.

Plugging in the values from the data, we get:

r = (5 x 198 - 39 x 91) / √((5 x 114 - 39²) x (5 x 187 - 91²))

Simplifying this equation gives us:

r = (-179) / √((-97) x (-6))

r = (-179) / √(582)

r = (-179) / 24.07

r = -7.44

The correlation coefficient is -7.44, which indicates a strong negative correlation. This means that as the value of x increases, the value of y decreases. Conversely, as the value of x decreases, the value of y increases.
