1. The first quartile (1) of the ages of the 256 employees of CCNHS – Main Campus is 39 years old. What does it imply?
Answers
If the first quartile is 39 years old, it means that approximately one-fourth of the employees at CCNHS – Main Campus are 39 years old or younger.
The first quartile (Q1) of the ages of the 256 employees of CCNHS – Main Campus being 39 years old implies that 25% of the employees have an age equal to or less than 39 years old.
In statistical terms, the first quartile represents the point below which 25% of the data falls. It divides the data set into four equal parts, with each part containing 25% of the data. Therefore, if the first quartile is 39 years old, it means that approximately one-fourth of the employees at CCNHS – Main Campus are 39 years old or younger.
This information provides insight into the age distribution of the employees at the institution. It indicates that a significant portion of the employees are relatively young, with a quarter of them falling below the age of 39. Understanding the age demographics of the workforce can be useful for various purposes, such as planning professional development programs or implementing age-specific policies.

What else must you know to prove the triangles congruent by ASA? By SAS?
Answers
Note that given the proof of congruence by SAS, the only thing remaining to know is that "2 corresponding sides and the corresponding included angles of both triangles are equal."
What is the rationale for the above response?The definition of SAS Congruency is as follows:
The SAS postulate states that two sides and the included angle of one triangle are identical to the corresponding two sides and the included angle of another triangle.
As demonstrated in the triangle, the angles mCAD and mACB are congruent. Thus; m∠CAD ≅ m∠ACB
Because m∠CAD and m∠ACB are congruent, AD and BC must also be congruent. Now, because AC is shared by both triangles ABC and ADC, we get two matching equal sides with the included corresponding equal angles.
As a result, the SAS Congruence postulate is proven.

Suppose that the functions f and g are defined as follows.
Find f.g and f+ g. Then, give their domains using interval notation.

The composite functions and their domains are (f . g)(x) = √(4x - 1)/(5x² + 3) and \((f + g)(x) = \frac{5x^2\sqrt{4x-1}+3\sqrt{4x-1}+1}{5x^2+3}\)
Domain: x ≥ 1/4
Calculating the composite functions and their domainsGiven that
f(x) = 1/(5x² + 3)
g(x) = √(4x - 1)
For the first pair, we have
(f . g)(x) = f(x) * g(x)
So, we have
(f . g)(x) = 1/(5x² + 3) * √(4x - 1)
Evaluate
(f . g)(x) = √(4x - 1)/(5x² + 3)
For the domain, we have
4x - 1 ≥ 0
x ≥ 1/4
Next, we have
(f . g)(x) = f(x) * g(x)
So, we have
(f + g)(x) = 1/(5x² + 3) + √(4x - 1)

Let α= 0.05
Since the sample sizes are large therefore the test statistic used under H0 is
The critical region for α= 0.05 for a one tailed test Z > ± 1.645
Z = (x`2- x`1) /s/ √n
Z= 154.8-128.746.5/√50

Answer:

Step-by-step explanation:
4 × 9 = \(\sqrt 36\) = \(\sqrt{6}\)
The value of y is 6 units obtained by applying pythagoars's theorem in all possible right-angled triangles.
What is Pythagoras's theorem?In a right-angled triangle, the sum of the squares of the smaller two sides of a right-angle triangle is equal to the square of the largest side.
From the figure, we have three unknowns x, y, and z and we have 3 right-angled triangles so three equations can be formed.
x² = 4² + y²...(i)
z² = 9² + y²...(ii)
(4 + 9)² = x² + z²
13² = x² + z²...(iii)
Now, Subtracting eqn(ii) from eqn(iii) we have.
169 = x² + z²
(-) 81 = -(y)² + z²
-------------------------
88 = x² + y²...(iv).
Now adding eqn(i) and eqn(iv) we have,
2x² = 104.
x² = 52.
Putting this value in eqn(i) we have,
52 = 16 + y².
y² = 36.

An open box is made from a 40 -cm by 50-cm piece of tin by cutting a square from each corner and folding the edges. The area of the resulting base is 1496cm squared. What is the length of the sides of the squares?
Answers
The length of the sides of the squares is 3 cm.
What is a rectangle?A rectangle is a quadrilateral with all four interior angles 90°.
Given that, the dimension of the rectangular tin piece is 40 cm by 50 cm.
Let the length of the sides of the square is x.
Then, the dimensions of the resulting rectangular base are (40 - 2x) by
(50 -2x).
Given that, the area of the resulting base is 1496 square cm.
Therefore, it follows:
(40 - 2x)(50 -2x) = 1496
2000 - 80x -100x + 4x² = 1496
4x² - 180x + 2000 -1496 = 0
4x² - 180x + 504 = 0
x² - 45x + 126 = 0
x² - 42x - 3x + 126 = 0
x(x- 42) - 3(x - 42) = 0
(x - 3)(x - 42) = 0
x-3 =0 or x - 42 = 0
x = 3 or x = 42
Note that the dimension of the rectangular tin piece is 40 cm by 50 cm, therefore, x = 42 cm cannot be the length of the square.

find the 55th term in the following arithmetic sequence: -102, -98,-94, -90, ...
Answers
We are given the following sequence:
\(-102,-98,-94,-90\)This is an arithmetic sequence that means that each term can be found by adding a constant term to the previous term. In this case, that constant term is 4, since:
\(\begin{gathered} -102+4=-98 \\ -98+4=-94 \\ -94+4=-90 \end{gathered}\)This term is called the common difference. The n-th term of an arithmetic sequence is given by:
\(a_n=a_1+(n-1)d\)Where:
\(\begin{gathered} a_1=\text{first term} \\ d=\text{common difference} \end{gathered}\)In this case, we have:
\(a_n=-102+(n-1)4\)Solving the operations we get:
\(a_n=-102+4n-4\)Simplifying:
\(a_n=-106+4n\)Now we replace "n = 55" since we want to find the 55th term:
\(a_{55}=-106+4(55)\)Solving the operations:
\(a_{55}=114\)Therefore the 55th term is 114

Computer games in which the players take the roles of characters are very popular. They go back to earlier tabletop games such as "Dungeons & Dragons." These games use many different types of dice. A four‑sided die has faces with one of the numbers 1,2,31,2,3 , or 44 appearing at the bottom of each visible face. In this case the sample space is ????={2,3,4,5,6,7,8}S={2,3,4,5,6,7,8} .
Suppose the strength of a character in a game is determined by rolling a four‑sided die twice and adding 22 to the sum of the numbers. Give a probability model (sample space and probabilities of outcomes) for the character’s strength.
(a) What is the sample space of the character's strength of a character?
????={1,2,3,4,5,6,7,8,9}S={1,2,3,4,5,6,7,8,9}
????={4,5,6,7,8,9,10}S={4,5,6,7,8,9,10}
????={3,5,7,9}S={3,5,7,9}

P(strength of a character=9):P(strength of a character=9):
In this probability model, what is the P(strength of a character = 13 )P(strength of a character = 13 ) ? (Enter your answer rounded to four decimal places.)
P(strength of a character=13):P(strength of a character=13):
Answers
The sample space of the character's strength is {3,4,5,6,7,8,9,10,11}. P(strength of a character = 4) = 1/9, P(strength of a character = 9) = 2/9, P(strength of a character = 13) = 1/9.
The sample space for the character's strength is {4,5,6,7,8,9,10,11}.
(a) The probability model for the character's strength is as follows:
P(strength of a character = 4) = 1/16
P(strength of a character = 5) = 2/16
P(strength of a character = 6) = 3/16
P(strength of a character = 7) = 4/16
P(strength of a character = 8) = 3/16
P(strength of a character = 9) = 2/16
P(strength of a character = 10) = 1/16
(b) P(strength of a character = 4) = 1/16
P(strength of a character = 9) = 2/16 = 1/8
P(strength of a character = 13) = 4/16 = 1/4

How to Interpret the degree of Polynomial functions?For polynomial functions f(x) and g(x), if deg(f) = m * deg(g) = n, then we have the following:
Option A: deg(f + g) = max(m, n)
This is true because we know that the degree of the sum of two polynomials is the maximum of their individual degrees.
Option B: deg(f * g) <= m + n
This is true because we know that the degree of the product of two polynomials is at most the sum of their individual degrees.
Option C: If g is a factor of f, then deg(f) <= m
This is true because If g is a factor of f, it means that f can be divided by g without leaving a remainder. In this case, the degree of f is less than or equal to the degree of g.
D. The deg(f ^ 3) = 3m
This is not true because the degree of the polynomial f raised to the power of 3 is not necessarily equal to 3 times the degree of f. The degree of f^3 will depend on the individual terms and their exponents.
