Is the mean of the following data is 18.75 then find the value of p?
The value of p is 20
Mean is the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers.
Mean = (Sum of all the observations/Total number of observations)
Is the mean of the following data is 18.75 then find the value of p?
Xi 10 15 p 25 30
Fi 5 10 7 8 2
We may prepare th frequency table as given below:
mean=(∑Fi *Xi) / ∑Fi
= (5*10 + 10*15 + 7*p + 8*25 + 2* 30)/ (5 + 10 +7 +8 +2)
= (460+7p)/ 32
=18.75
460+7p=(18.75×32)
⇒(460+7p)=600
⇒7p=140
⇒p=20

When data are transformed to ranks and the Pearson correlation is performed, the Spearman correlation is what is obtained as a correlation.
What is meant by correlation?A statistical measure known as correlation expresses how linearly connected two variables are (meaning they change together at a constant rate). It is a typical strategy for describing straightforward relationships without explicitly stating cause and effect. The degree of a linear link between two quantitative variables is measured by the term "correlation." The degree to which two or more variables change in relation to one another is indicated by the statistical concept of correlation. A statistical metric known as correlation, which is given as a number, describes the strength and direction of a relationship between two or more variables.Therefore, the correct answer is A)the Spearman correlation

8. Solve the Right Triangle.
The length of the perpendicular of the right-angle triangle will be 20.4 meters.
What is a right-angle triangle?It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.
The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The Pythagoras theorem formula is given as
H² = P² + B²
The hypotenuse is 30 m and the base is 22 m. Then the length of the perpendicular is given as,
30² = P² + 22²
900 = P² + 484
P² = 900 - 484
P² = 416
P = 20.4 m

what is the value of y if the slope of the line is 3 and two points on the line is (0,y) and (2,4)
The value of y is -2.
What is coordinate of point?
The coordinates are a pair of numbers that, using the horizontal and vertical lines, precisely pinpoint a point's location on a cartesian plane. typically represented by (x, y), the point's x and y values on a graph. There are two coordinates in every point or ordered pair.
Given points are (0,y) and (2,4).
The formula of slope of a line that passes through the points (x₁, y₁) and (x₂, y₂) is (y₂ - y₁)/(x₂ - x₁).
The slope of the given line is (4 - y)/(2 - 0) = (4 - y)/2.
Again given that the slope of the line is 3.
Therefore,
(4 - y)/2 = 3
Multiply both sides by 2
4 - y = 6
Subtract 4 from both sides:
-y = 2

To prove m∠ = m∠2.
Then,
m∠3 + m∠2 = 180m∠1 + m∠3 = 180m∠1 = m∠2How to prove corresponding angles?The corresponding angles theorem states that If two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent.
Corresponding angles are formed when a transversal passes through two lines.
As we know that line segment m is parallel to the line segment n.
m || n .
Hence,
m∠3 + m∠2 = 180 (same interior angles)
Same side interior angles are two angles that are on the same side of the transversal and on the interior of (between) the two lines.
Same side interior angles are supplementary.
m∠1 + m∠3 = 180(sum of angles on a straight line)

Any equation of the form where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
In mathematics, a dimension is the length or width of an area, region, or space in one direction.
area = length × width
a = l × w
But, we want to triple than area;
3A = 3 (l × w)
3A = (k × l) (k × w)
k² = 3
k = √3

Increased Dimension: 6√3 - 6 and 3√3 - 3
let x is the amount of increase in each side:
(x + 6) (x + 3) = 3(18)
x² + 3x + 6x + 18 = 54
x² + 9x + 18 = 54

How do you find the rate of change on a line graph?
To get the slope of a graphed function, use the average rate of change formula. Divide the change in y-values by the change in x-values to determine the average rate of change.
The slope, rise over run, or change in over the change in of a line determines its rate of change. A graph's slope triangle or two points in a table can be used to compute the slope.
It is frequently referred to as rate of change when determining the slope of real-world scenarios. "Rate of change" and "slope" have the same meaning. Use the slope formula or create a slope triangle if you are asked to determine the rate of change.

At the rate given, how many kilometers can Mikaela bike in 1 hour?
If Mikaela runs for 1 hour and bikes for 1 hour at the rates given, how far will she travel
Answer:
Mikaela run 10 km in 1hour
Mikaela bikes 25km in 1hour
35km If Mikaela runs for 1 hour and bikes for 1 hour at the rates given
Step-by-step explanation:
Let's solve how many km Mikaela runs in 1 hour.
0.5 hour = 30 minutes
5km = 30 minutes
10km = 60 minute
Let's solve how many km Mikaela bikes in 1 hour.
0.8 hour = 48 minutes
20km = 48 minutes
To get from 48 minutes to 60 minutes, we times 1.25. So, we take 20 times 1.25 = 25km
So, Mikaela bikes 25km in 1 hour.
Let's solve how far she traveled If Mikaela runs for 1 hour and bikes for 1 hour at the rates given
10km+ 25km = 35km

the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 4x - 2 ← is in slope- intercept form
with slope m = 4
given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{4}[/tex] , then
y = - [tex]\frac{1}{4}[/tex] x + c ← is the partial equation

The roots of the quadratic equation 2x^2 + 5x + 3 are the two values of x that make the equation equal to 0. These two values are x = -3 and x = -1/2.
The roots of a quadratic equation are the two values of x that make the equation equal to 0. To find the roots of the equation 2x^2 + 5x + 3, we need to set the equation equal to 0 and solve for x. We can do this by using the Quadratic Formula, which states that the two roots of a quadratic equation ax^2 + bx + c = 0 are x = [-b +/- sqrt(b^2 - 4ac)] / 2a. In this equation, a = 2, b = 5, and c = 3. We can plug these values into the formula to get x = [-5 +/- sqrt(25 - 24)] / 4. Simplifying this expression gives us x = -3 and x = -1/2, which are the two roots of the equation 2x^2 + 5x + 3.

What is the sample correlation coefficient?Generally, r represents the sample correlation coefficient, which is a measure of the strength and direction of the linear relationship between two variables in a sample of data. It ranges from -1 to 1, where -1 represents a perfect negative correlation, 0 represents no correlation, and 1 represents a perfect positive correlation.
p represents the p-value, which is a measure of the statistical significance of the sample correlation coefficient. It represents the probability that the observed correlation occurred by chance, assuming that there is no true correlation in the population.
A p-value of less than 0.05 is often used as a threshold for determining statistical significance, meaning that the observed correlation is unlikely to have occurred by chance and is likely to reflect a true correlation in the population.
