What is a right angle triangle?
A right triangle, also known as a right-angled triangle, right-perpendicular triangle, orthogonal triangle, or formerly rectangled triangle, is a triangle with one right angle, or two perpendicular sides. The foundation of trigonometry is the relationship between the sides and various angles of the right triangle.
Given that, in △BCD
BD = 24 m

if a data set is symmetrical, which statistical measure best represents the entire spread of the data set?
Answers
The best statistical measure to represent the entire spread of the data set when a data set is symmetrical is the standard deviation.
The standard deviation is a measure of how much the individual data points vary from the mean of the data set.
It is calculated by taking the square root of the variance.
It is the average of the squared differences of each data point from the mean.
In a symmetrical data set, the mean, median, and mode are all equal and located at the center of the data set.
This represents that the data points are evenly distributed around the center.
The standard deviation can provide a good measure of the spread of the data points from this center.
Other measures of spread representing the range or interquartile range, may not be as useful in a symmetrical data set .
As they are more affected by outliers and skewness in the data.
Therefore, the symmetrical data set in best way represented by statistical measure known as standard deviation.

Hope high school has three elective courses for social studies and four electives for science. how many ways are there for alex to select three electives from them this semester with at least one from each subject?
Answers
Using the Fundamental Counting Theorem, it is found that there are 60 ways for Alex to select three electives from them this semester.
What is the Fundamental Counting Theorem?It is a theorem that states that if there are n things, each with \(n_1, n_2, \cdots, n_n\) ways to be done, each thing independent of the other, the number of ways they can be done is:
\(N = n_1 \times n_2 \times \cdots \times n_n\)
In this problem, we have that:
The first choice is one of three of social studies, hence \(n_1 = 3\).The second choice is one of four from science, hence \(n_2 = 4\).The third choice is any of the remaining 5, hence \(n_3 = 5\).Then the number of ways is given by:
N = 3 x 4 x 5 = 60.

Answers
Given that the equation of the line in the diagram is `y = 5 - x`. The line cuts the y-axis at P. So, the coordinates of point P are (0,5) and the gradient of the line is `-1`.
The equation of the line can be written as `y = -1x + 5`.Therefore, the y-intercept of the line is 5. Therefore, the coordinates of point P are (0,5).
To find the gradient of the line, we have to write the equation of the line in the form of `y = mx + c`.
We can rewrite `y = -1x + 5` as `y = (-1)x + 5`.From the above form of the equation, we can see that the gradient `m` is `-1`.Therefore, the gradient of line 1 is `-1`.Hence, the required answer is: Coordinates of point P is `(0,5)`.The gradient of the line is `-1`.

The population's standard deviation is equal to the standard deviation (Error) of the mean.
Let the population's standard deviation be x
2 = x / \(\sqrt{36}\)

If the standard deviation is to be decreased to 1.2

Can someone help me with this Question.
Answers
The formula we need to use is given above. In this formula, we will substitute the desired values. Let's start.
\(P=3W+D\)A) First, we can start by analyzing the first premise. The team has \(8\) wins and \(5\) losses. It earned \(8 \times 3 = 24\) points in total from the matches it won and \(1\times5=5\) points in total from the matches it drew. Therefore, it earned \(24+5=29\) points.
B) After \(39\) matches, the team managed to earn \(54\) points in total. \(12\) of these matches have ended in draws. Therefore, this team has won and lost a total of \(39-12=27\) matches. This number includes all matches won and lost. In total, the team earned \(12\times1=12\) points from the \(12\) matches that ended in a draw.
\(54-12=42\) points is the points earned after \(27\) matches. By dividing \(42\) by \(3\) ( because \(3\) points is the score obtained as a result of the matches won), we find how many matches team won. \(42\div3=14\) matches won.
That leaves \(27-14=13\) matches. These represent the matches team lost.
Finally, the answers are below.
\(A)29\)
\(B)13\)
Answer:
a) 29 points
b) 13 losses
Step-by-step explanation:
You want to know points and losses for different teams using the formula P = 3W +D, where W is wins and D is draws.
A 8 wins, 5 drawsThe number of points the team has is ...
P = 3W +D
P = 3(8) +(5) = 29
The team has 29 points.
B 54 pointsYou want the number of losses the team has if it has 54 points and 12 draws after 39 games.
The number of wins is given by ...
P = 3W +D
54 = 3W +12
42 = 3W
14 = W
Then the number of losses is ...
W +D +L = 39
14 +12 +L = 39 . . . substitute the known values
L = 13 . . . . . . . . . . subtract 26 from both sides
The team lost 13 games.
__
Additional comment
In part B, we can solve for the number of losses directly, using 39-12-x as the number of wins when there are x losses. Simplifying 3W +D -P = 0 can make it easy to solve for x. (In the attached, we let the calculator do the simplification.)

Which value of AB would make line EB parallel to line DC?
Answers
The value of AB in triangle ADC and AEB such that it make line EB parallel to line DC is given by to option d. 36.
To make line EB parallel to line DC,
Ensure that triangle AED and triangle ABC are similar triangles.
This can be achieved by having the corresponding sides of the triangles in proportional lengths.
Let us find the value of AB that would make line EB parallel to line DC.
In triangle AED, we have AE = 51 and ED = 17.
In triangle ABC, we have BC = 12.
If the triangles are similar, then the ratio of corresponding sides should be equal.
This implies,
AB/BC = AE/ED
Plugging in the values we get,
⇒ AB/12 = 51/17
Cross-multiplying and get the value ,
⇒ AB × 17 = 12 × 51
⇒ AB = (12 × 51) / 17
⇒ AB = 36
Therefore, the value of AB that would make line EB parallel to line DC is equal to option d. 36.
