In a group of students 25% are enrolled in physics, 23% in sociology, 17% in chemistry, 14% in political science, 12% in anthropology, and 9% in math. you are going to select an individual from the group of students. the probability of event a is equivalent to the probability that you select someone who studies social science (sociology, political science and anthropology) or physics. what is the probability of the event a’s complement?
The probability of event A's complement, which signifies selecting a student not studying social science or physics, is 26%.
The probability of selecting someone who studies social science (sociology, political science, and anthropology) or physics is the sum of the individual probabilities for those subjects: 23% (sociology) + 14% (political science) + 12% (anthropology) + 25% (physics) = 74%. To find the probability of the event A's complement, which is selecting a student not studying any of these subjects, we subtract the probability of event A from 100%: 100% - 74% = 26%. Therefore, the probability of selecting a student not enrolled in any of the mentioned social science subjects or physics is 26%.

A brick oven has an opening as shown. What is the area of the entire opening?
Answer:
[tex]13.93ft^{2}[/tex]
Step-by-step explanation:
The area of the opening will be the sum of the area of the two shapes shown which are rectangle and half ellipse:
[tex]Area =Area_{rectangle}+\frac{1}{2} Area_{Ellipse}[/tex]
The area of the rectangle is:
[tex]Area_{Rectangle}=a*b[/tex]
where:
[tex]a=4ft\\b=2\frac{1}{2}ft[/tex]
we replace values(we convert the mixed fraction to improper fraction by multiplying the whole number part by the fraction's denominator, then add that to the numerator then write the result on top of the denominator.):
[tex]Area_{Rectangle}=4*2\frac{1}{2} =4*\frac{5}{2}=10[/tex]
The area of the ellipse is:
[tex]Area_{Ellipse}=a*b*\pi[/tex]
where:
[tex]a=Radius1=1\frac{1}{4}ft\\b=Radius2=2ft\\[/tex]
Radius2 will be half the side of the rectangle
[tex]Radius2=\frac{4}{2}=2[/tex]
we replace the values:
[tex]Area_{Ellipse}=1\frac{1}{4} *2*\pi=\frac{5}{4}*2*\pi=\frac{5}{2}\pi =7.85[/tex]
we calculate now the total area:
[tex]Area =Area_{rectangle}+\frac{1}{2} Area_{Ellipse}\\Area=10+\frac{1}{2}(7.85)=10+3.93=13.93ft^{2}[/tex]

In a plane, line N is parallel to line O, Line O is parallel to P, and line L is perpendicular to line N. Which must be true?
A) N||L
B) N||P
C) L||O
D) P||L
Answer:
The correct answer is option B) N || P
Step-by-step explanation:
N || P.
As it is given, in a plane, line N is parallel to line O, Line O is parallel to P, and line L is perpendicular to line N.
Since, N is parallel to O, and O is parallel to P, then N must be parallel to P.
So, option B is correct.
given that (6 3) is on the graph of f(x) find the corresponding point for the function f(-1/2x)
Answer:
this answer is wrong on plato, trust me
Step-by-step explanation:
We need to find the corresponding y-coordinate for x = -3. Unfortunately, since we don't have additional information about the function f(x), we cannot determine the value of f(-3) and provide the corresponding point.
To find the corresponding point for the function f(-1/2x) when (6, 3) is on the graph of f(x), we need to substitute the x-coordinate of (6, 3) into the function -1/2x and determine the resulting y-coordinate.
Given that (6, 3) is on the graph of f(x), it means that f(6) = 3.
Now let's substitute -1/2x into the function:
f(-1/2x) = f(-1/2 * 6) = f(-3)
Therefore, we need to find the corresponding y-coordinate for x = -3. Unfortunately, since we don't have additional information about the function f(x), we cannot determine the value of f(-3) and provide the corresponding point.
In summary, without more information about the function f(x), we cannot find the corresponding point for the function f(-1/2x) when (6, 3) is on the graph of f(x).

What is the discriminant of the polynomial below? 4x2 - 20x + 25
The discriminant of the given polynomial is 0, indicating one real root.
Explanation:The discriminant of a quadratic equation is a value that can be used to determine the nature of the solutions (roots) of the equation. It is calculated using the formula b^2 - 4ac, where a, b, and c are the coefficients of the equation.
In the given polynomial, the coefficients are a = 4, b = -20, and c = 25. Plugging these values into the formula, we get: (-20)^2 - 4(4)(25) = 400 - 400 = 0.
Since the discriminant is equal to zero, the polynomial has one real root.

What, roughly, is the percent uncertainty in the volume of a spherical beach ball whose radius is r = 2.86 plus or minus .09 m?
Final answer:
To calculate the percent uncertainty in the volume of a spherical beach ball when the radius is uncertain, you multiply the square of the radius by four (surface area), by the uncertainty in the radius, and then compare this value to the total volume. The percent uncertainty is found to be approximately 2.62%.
Explanation:
To determine the percent uncertainty in the volume of a spherical beach ball with a radius of 2.86 1 0.09 meters, one must first calculate the volume's uncertainty, then relate this to the total volume, and finally convert this relationship into a percentage.
The formula for the volume of a sphere is [tex]V = (4/3)\pi(r^3)[/tex]. Since volume is proportional to the cube of the radius, any uncertainty in the radius dramatically affects the volume uncertainty. Using a function for the volume V(r) and applying the approximation for small changes in r, we have:
[tex]V = (4/3)\pi(r^2))(r)[/tex]
For a radius of 2.86 meters and an uncertainty of 0.09 meters, the uncertainty V in volume is 170 [tex]cm^3[/tex]. The volume is approximately V = [tex](4/3)(3.14)(2.86^3)[/tex] = 6538 [tex]cm^3[/tex]. Therefore, the volume expressed with its uncertainty is [tex]6500 \pm170[/tex] [tex]cm^3,[/tex] rounded to avoid false precision.
To find the percent uncertainty:
Convert the uncertainty to the same units as the ball's volume if needed (here both are in cm^3).
Divide the uncertainty by the volume: (170/6500) x 100%.
The percent uncertainty is approximately 2.62%.
if a circle is inscribed in a triangle, the center of the circle is called the _____ of the triangle.
A. radius
B. incenter
C. circumcenter
Answer:
The correct answer to the following question will be Option B (Incenter).
Step-by-step explanation:
The middle of the circle which is carved in a triangle is the triangle incenter, the point where the triangle angle bisectors cross.
There are following steps to construct an inscribed circle in a triangle are as follows:
Step 1: Create the incenter.
Step 2: Construct a line that passes through incenter, perpendicular to one side of the triangle. The segment which connects the incenter with the triangle intersection point and the perpendicular line is the circle radius.
Step 3: Build a centered circle at the incenter with radius spotted in step 2.

A state’s license plates consist of 3 letters followed by 3 numbers. What is the probability of randomly generating a license plate that reads AHW 304?
Answer: [tex]\frac{1}{17576000}[/tex]
Step-by-step explanation:
Given: A state’s license plates consist of 3 letters followed by 3 numbers.
Since, there are 26 letters in English alphabet and 10 digits in set of numbers(0,1,....,9).
Then , the total number of license plates can be generated (if repetition is allowed)=
[tex]26\times26\times26\times10\times10\times10=17576000[/tex]
In AHW304, each alphabet and number occurs only once, the number of license plate with this = 1

Use the drop-down menus to complete each statement to show why √65 is between 12 and 18.
Answer:
12 < 6√5 < 18
Step-by-step explanation:
It has been given in the question 4 < 5 < 9 and we have to show 6√5 is between 12 and 18.
For box number 1.
4 < 5 < 9 ⇒ √4 < √5 < √9
For the box number 2.
√4 < √5 < √9 ⇒ 2 < √5 < 3
For the box number 3.
we multiply the inequality by 6.
6×(2 < √5 < 3) ⇒ 6×2 < 6×√5 < 6×3
Therefore final answer is 6×2 < 6×√5 < 6×3 ⇒ 12 < 6√5 < 18
The square root of 65 (√65) falls between 8 and 9, as these are the square roots of the closest perfect square numbers (64 and 81 respectively). The range of 12 to 18 provided in the question seems incorrect.
Explanation:The student's question is referring to the mathematical concept of square roots of numbers. The square root of a number is a value which, when multiplied by itself, yields the original number. In the case of √65, we need to locate it between two perfect square numbers, which are 64 (8^2) and 81(9^2). As a result, √65 should fall between 8 and 9.
However, the interval of 12 and 18 as stated in the question seems to be a mistake, as they are not the correct boundaries for the value of √65. Please verify the numbers in your question.

A right triangle has a side with length 12 in and a hypotenuse with length 20 in. find the length of the second leg (in inches). (round to the nearest hundredth if needed)
Graph the following piecewise function and then find the range.
Answer:
The correct option is 3.
Step-by-step explanation:
The given piecewise function is
[tex]f(x)=\begin{cases}3x^2+1 & \text{ if } -4<x<6 \\ 6 & \text{ if } 6\leq x<9 \end{cases}[/tex]
Range is the set of output or y values.
The given function for 6 ≤ x < 9 is
[tex]f(x)=6[/tex]
It is a constant function, the value of function is 6 for all values of x.
Range = 6
The given function for -4 < x < 6 is
[tex]f(x)=3x^2+1[/tex] .... (1)
It is a quadratic function.
The vertex form of a quadratic function is
[tex]f(x)=a(x-h)^2+k[/tex] ....(2)
Where (h,k) is vertex and a is constant.
From (1) and (2), we get a=3,h=0,k=1.
The vertex of this function is (0,1), it means the range of this function is greater than or equal to 1. But this function is only defined for -4 < x < 6.
[tex]f(-4)=3(-4)^2+1=49[/tex]
[tex]f(6)=3(6)^2+1=109[/tex]
The maximum value of the maximum value of the function is 109 at x=6. Since 6 is not included in the interval -4 < x < 6, therefore 109 is not included in the range.
Range = [1,109)
When we combined the range of both functions we get
Range = [1,109)
Therefore the correct option is 3.
