the time, in minutes, it took each of 11 students to complete a puzzle was recorded and is shown in the following list, along with the five-number summary. 9, 17, 20, 21, 27, 29, 30, 31, 32, 35, 58
Based on the 1.5 × IQR rule for outliers, there is no evidence to support the student's claim because there is only one outlier at 58 minutes.
What is an outlier?An outlier is also referred to as anomalous data and it can be defined as a numerical value that is either unusually too small or large (big) in comparison with the overall pattern of the numerical values contained in a data set.
What is an interquartile range?IQR is an abbreviation for interquartile range and it can be defined as a measure of the middle 50% of data values when they are ordered from lowest to highest.
Mathematically, interquartile range (IQR) is the difference between quartile 1 (Q₁) and quartile 3 (Q₃):
IQR = Q₃ - Q₁
Based on the given data set, the following interquartile ranges was calculated by using Excel:
Q₃ = 31.5
Q₁ = 20.5
Now, the interquartile range (IQR) is given by:
IQR = Q₃ - Q₁
IQR = 31.5 - 20.5
IQR = 11
Based on the 1.5 × IQR rule for outliers, we have:
1.5 × IQR = 1.5 × 11 = 16.5
Therefore, our fences will be 16.5 points below Q₁ and 16.5 points above Q₃:
Lower fence = 20.5 - 16.5 = 4.5
Upper fence = 4.5 + 31.5 = 36.
In conclusion, we can reasonably infer and logically deduce that there is no evidence to support the student's claim because there is only one outlier at 58 minutes.

Find 5 numbers that have a mean of 40 and a median and deviationof 35 and a mode of 25.
The 5 number are 25, 25, 35, 45 and 70 that has the mean of 40 and a median and deviation of 35 and a mode of 25.
Mean:
Mean is the sum of all observations divided by the number of observations.
Median:
Median defines the value of the middlemost observation, obtained after arranging the data in ascending or descending order.
Mode:
The value which appears most often in the given data i.e. the observation with the highest frequency is called a mode of data.
Given,
Mean = 40
Median = 35
Mode = 25
We know that the mean value is is the sum of all observations divided by the number of observations.
So, Let us consider v,w,x,y,z are the five numbers.
So it can be written as,
[tex]Mean=\frac{v+w+x+y+z}{n}[/tex]
We know that,
Mean = 40 and n = 5.
Then,
[tex]40=\frac{v+w+x+y+z}{5}[/tex]
Therefore,
=> v + w + x + y + z = 40 x 5
=> v + w + x + y + z = 200 --------------------------(1)
Here we know that the Median is 35.
The median in equation (1) is x,
So x = 35
And the mode is 25, we know that definition of mode so let us consider it will occurs at least twice,
So, the values of v = 25 and u = 25
Now apply the values on the equation,
=> 25 + 25 + 35 + y + z = 200
=> 85 + y + z = 200
=> y + z = 200 - 85
=> y + z = 115
So, here we have to take the combinations that gives the value of 115 and the values must be greater than 35.
So, the values are 45 and 70.
Therefore, the five numbers are 25, 25, 35, 45 and 70.

Draw a pair of intersecting lines that forms a pair of complementary angles. Explain your reasoning.
A pair of intersecting lines that forms a pair of complementary angles is as drawn below.
What are the pair of complementary angles?
Remember that complementary angles are defined as angles which sum is equal to 90°.
Besides, each of the pairs of opposite angles made by two intersecting lines are called vertical angles. Now, from congruent proofs, we know that that vertical angles are congruent. In another words, they have the same measure.
Thus, we have to draw two vertical angles that measure:
90° ÷2 = 45°

Step-by-step explanation:
The graph g(x) = sin (x + 2π) is a transformation of the graph f(x) = sin x exactly one period to the right, and the two graphs look identical. Is it true or false and explain why
It is true that the two graphs of g(x) = sin (x + 2π) and f(x) = sin x are identical.
How to Interpret Graph Transformations?The sine function is a periodic function, which means that the value of the sine function repeats itself after a regular interval. This regular interval is called the period. The period for a sine function is 2π radians. This means that the value of the sine function will be same for any two points separated by 2π radians.
If x = 0, then sin (x) = sin (0) = 0 and sin (x + 2π) = sin (0 + 2π) = sin (2π) = 0
If x = π/2, then sin (x) = sin (π/2) = 1 and sin (x + 2π) = sin (π/2 + 2π) = sin (5π/2) = 1
Thus, it can be seen that the graph of sin (x + 2π) replicates the graph of sin (x) exactly after one period of the sine function.
Thus, we conclude that it is true that the two graphs of g(x) and f(x) are identical.

Answer:
y = 0.24 or y = - 29.76==============================
Identity of the square of a sum of two numbers:
(a + b)² = a² + 2ab + b²Given equation:
y² + 30y = - 7We can see one of the numbers is y, and the second one is 15 as twice the product is 30y.
Add 15² = 225 to both sides to complete the square, then solve it:
y² + 2*15y + 15² = 225 - 7(y + 15)² = 218y + 15 = ± √218y = - 15 ± √218y = - 15 ± 14.76 (rounded to the nearest hundredths)y = 0.24 or y = - 29.76Answers:
y = ± 221.47, y = -0.24, y = -29.76
Step-by-step explanation:
y^2 + 30y = -7
Move -7 over to the other side
y^2 + 30y +7 = 0
This takes form of a quadratic equation of ax^2 + bx + c = 0, where y = x
Quadratic formula is x = (-b ± (sqrtb^2 - 4ac)/2a and replace everything so it's y = (-30 ± (sqrt30^2 - 4*1*7)/2*1. Once solved, the answer choices are y = ± 221.47, y = -0.24, or -29.76.

What is intersection?A third item made up of everything that is simultaneously contained in all of the other things is called an intersection of two or more objects in mathematics. In Euclidean geometry, for instance, the intersection of two lines in a plane that are not parallel is where they come together. More broadly, the set of elements that are a part of all of the sets is what is meant by the intersection of sets in set theory. The items being considered do not need to be in a shared space, unlike the Euclidean concept.
A point is the most frequent shape for an intersection in plane geometry, while there are other shapes that can be used as well. An intersection is an item of lesser dimension that is incident to each in incidence geometry, which is typically applied to flats.

Answer:
65a-15a^2
Step-by-step explanation:
Find the distance between C ( 2 , 4 ) and D ( 5 , 7 ) . Round to the nearest tenth, if necessary.
The distance between the points is 4.3.
Given the points are C(2,4) and D (5,7)
let the two points be:
C (2,4) = (x₁ , y₁)
D (5,7) = (x₂ , y₂)
The length of the section of a line connecting any two places represents their distance. Only one line connects the two places, and it passes through both. The length of the line segment that connects the two places may therefore be used to compute the distance between them.
Distance between the points = √(x₂ ₋ x₁)² ₊ (y₂ ₋ y₁)²
substitute the points.
d = √(5 ₋ 2)² ₊ (7 ₋ 4)²
d = √(3)² ₊ (3)²
d = √9 ₊ 9
d = √18
d = 4.24
rounding off to nearest tenth
d = 4.3
Hence we get the distance between two points as 4.3.

Point R is on line segment QS. Given QR = 4, QS = 4x, and RS = 5x – 9,
determine the numerical length of RS.
Answer: RS
The numerical length of RS is 16.
Given, Point R is on line segment QS.
A line segment in geometry has two different points on it that define its boundaries. A stretch of a line that connects two locations is frequently referred to as a line segment. A line has no ends and can continue indefinitely in either direction, which is how it differs from a line segment.
QR = 4 , QS = 4x and RS = 5x ₋ 9
we know that, QS ₊ RS = QR
⇒ RS = QR ₋ QS
⇒ 5x ₋ 9 = 4x ₋ 4
unknown items move to the left of the equal sign and known items move to the right of the equal sign.
5x ₋ 4x = 9 ₋ 4
x = 5
therefore, RS = 5x ₋ 9
= 5(5) ₋ 9
= 25 ₋ 9
= 16
hence we get the length of RS as 16.
