The first quartile being 39 years old indicates a relatively younger age profile among the employees at CCNHS – Main Campus.
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.
To solve the problem, we need to understand the concept of quartiles. In statistics, quartiles divide a data set into four equal parts. The first quartile represents the point below which 25% of the data falls.
In this case, since 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. It suggests that there is a significant proportion of younger employees within the institution. Understanding the age demographics can be important for various purposes such as human resources planning, identifying generational differences, and designing age-appropriate policies or programs.
Overall, the first quartile being 39 years old indicates a relatively younger age profile among the employees at CCNHS – Main Campus.

1) The area of a circle circumscribed about a square is 307.7 cm².
2.a.) The angle ACB is 39 degrees.°.
2b.) The value of x is 5.42.
How to determine the area of a circle?We shall find the radius to determine the area of a circle.
First, find the side length of the square:
Since the perimeter of the square = 56 cm, then, each side of the square is 56 cm / 4 = 14 cm.
Next, find the diagonal of the square, using the Pythagorean theorem:
Diagonal = the diameter of the circumscribed circle.
Diagonal² = side length² + side length²
= 14 cm² + 14 cm²
= 196 cm² + 196 cm²
= 392 cm²
Take the square root of both sides:
Diagonal = √392 cm ≈ 19.80 cm (rounded to two decimal places)
Then, the radius of the circle which is half the diagonal:
Radius = Diagonal / 2 ≈ 19.80 cm / 2 ≈ 9.90 cm (rounded to two decimal places)
Finally, compute the area of the circle using the formula:
Area = π * Radius²
Area = 3.14 * (9.90 cm)²
Area ≈ 307.7 cm² (rounded to two decimal places)
Therefore, the area of the circle that is circumscribed about a square with a perimeter of 56 cm is 307.7 cm².
2. a) We use the property of angles in a circle to solve for angle ACB: an angle inscribed in a circle is half the measure of its intercepted arc.
Given that arc AB has a measure of 78°, we can find angle ACB as follows:
Angle ACB = 1/2 * arc AB
= 1/2 * 78°
= 39°
Therefore, the angle ACB is 39 degrees.
2b.) To solve for the value of x, we use the information that the angle ADB = (3x - 12)⁴.
Given that angle ADB is (3x - 12)⁴, we can equate it to the measure of the intercepted arc AB, which is 78°:
(3x - 12)⁴ = 78
Solve the equation for x, by taking the fourth root of both sides:
∛∛((3x - 12)⁴) = ∛∛78
Simplify,
3x - 12 = ∛(78)
Isolate x by adding 12 to both sides:
3x - 12 + 12 = ∛(78) + 12
3x = ∛(78) + 12
Finally, divide both sides by 3:
x = (∛(78) + 12) / 3
x = (4.27 +12) / 3
x = 5.42
So, x is 5.42
Therefore,
1) The area of the circle is 154 cm².
2a.) Angle ACB is equal to 102°.
2b.) The value of x is 5.42

If you know the answer answer it with the explanation thank you.
The four numbers are 1, 5, 11, and 23.
Four numbers have a mean of 10 and the median is 8. Two of the numbers are 1 and 5. The other two numbers must be 11 and 23.
The mean of a set of numbers is calculated by adding all of the numbers and dividing by the number of numbers. In this case, the mean is 10, so the sum of the four numbers is 40. We already know that two of the numbers are 1 and 5, so the other two numbers must add up to 34.
The median of a set of numbers is the middle number when the numbers are arranged in ascending order. In this case, the median is 8, so the third number must be 8. This leaves the fourth number to be either 11 or 23.
If the fourth number is 11, then the mean of the four numbers will be 9.5, which is not correct. Therefore, the fourth number must be 23.

Write this definition as a biconditional statement.
A rectangle is a parallelogram with four right angles.
the sum of two numbers is 59. the didference between the two numbers is 11 which is the smaller of the two numbers
The larger number is 35.Let's assume the two numbers are represented by the variables "x" and "y," where "x" is the smaller number.
Equation 1: x + y = 59 (The sum of the two numbers is 59)
Equation 2: x - y = 11 (The difference between the two numbers is 11, with the smaller number being y)
According to the given information, the sum of the two numbers is 59, which can be expressed as:
x + y = 59
The difference between the two numbers is 11, with "x" being the smaller number. This can be expressed as:
y - x = 11
We can now solve these two equations simultaneously to find the values of "x" and "y."
Rearranging the first equation to solve for "y" gives us:
y = 59 - x
Substituting this value of "y" into the second equation:
(59 - x) - x = 11
Simplifying the equation:
59 - 2x = 11
Subtracting 59 from both sides:
-2x = 11 - 59
-2x = -48
Dividing both sides by -2:
x = -48 / -2
x = 24
Therefore, the smaller number is 24. To find the larger number, we substitute the value of "x" into the first equation:
24 + y = 59
y = 59 - 24
y = 35.

A house on the market was valued at 432,000. After several years, the value decreased by 9%. By how much did the house's value decrease in dollars? What is the current value of the house?
Answer:
$393,120
Step-by-step explanation:
To find the decrease in the house's value in dollars, we need to calculate 9% of the initial value:
Decrease in value = (Initial value) * (Percentage decrease) = $432,000 * 9%
Converting the percentage to a decimal:
Decrease in value = $432,000 * 0.09 = $38,880
The house's value decreased by $38,880.
Now, to find the current value of the house, we need to subtract the decrease in value from the initial value:
Current value = Initial value - Decrease in value = $432,000 - $38,880 = $393,120
The current value of the house is $393,120.
Hope this helps!
