A certain type of legal proceeding has three possible outcomes: in favor of party a, in favor of party b, or not in favor of either party. The outcomes are expected to be 40 percent, 20 percent, and 40 percent, respectively. A random sample of 40 cases is selected from a certain judge to investigate whether the judge’s outcomes are consistent with the expected outcomes. A chi-square goodness-of-fit test is conducted, and the value of the chi-square test statistic is χ2=9. 19 with a corresponding p–value of 0. 1. Assuming the conditions for inference were met, which of the following is the correct interpretation of the p–value?
Answer:
D) If the null hypothesis is true, there is a 1 percent chance of obtaining a chi-square value of at least 9.19.
Explanation:
Most of this AP question is fluff to confuse you, so make sure to emphasize the p-value and the actual question being asked.
For these interpretation problems, for chi-square GOF (goodness of fit) tests, the p-value is interpreted as such:
If the null hypothesis ([tex]H_o[/tex]) is true, there is a [[tex]p[/tex]-value] probability of obtaining a chi-square ([tex]x^2[/tex]) value of [test-statistic [tex]x^2[/tex]] or more extreme.

The radius of circle c is 6 units and the measure of central angle acb is radians. What is the approximate area of the entire circle? square units what is the approximate area of the entire sector created by central angle acb? square units what is the approximate area of the shaded region only? square units.
Answer:
113
28
22
Explanation:
Area of shaded region ≈ 95.2 square units, Area of entire circle ≈ 113.1 square units.
What is circumference?The circumference is the perimeter of a circle or ellipse in geometry. That is, the circumference would be the circle's arc length if it were opened up and straightened out to a line segment.
The first step is to find the measure of the central angle acb in radians:
Since the radius of circle c is 6 units, the diameter of the circle is 2*6 = 12 units. Therefore, the circumference of the circle is:
C = πd = π(12) = 12π units
The central angle acb cuts off a portion of the circumference that is proportional to its measure, so we can set up the following proportion to find the measure of the central angle in radians:
(angle measure)/(360°) = (arc length)/(circumference)
Where the arc length is the length of the portion of the circumference cut off by the central angle.
Substituting the given values, we get:
(angle measure)/360° = x/(12π)
Simplifying, we get:
(angle measure) = 360°(x/(12π)) = 30x/π
Now we can use this value to calculate the area of the entire circle and the area of the sector created by central angle acb:
Area of entire circle = [tex]\pi r^2[/tex] = π[tex](6)^2[/tex] ≈ 113.1 square units
Area of sector acb = (1/2)[tex](6^2)[/tex](angle measure) = (1/2)(36)(30x/π) = 540x/π square units
To find the area of the shaded region, we need to subtract the area of triangle abc from the area of sector acb.
The central angle acb is divided into two congruent angles of measure x/2, so the angle measure of triangle abc is (180° - x)/2. We can use the Law of Cosines to find the length of side ab:
[tex]ab^2[/tex] = [tex]ac^2 + bc^2[/tex] - 2acbc cos((180° - x)/2)
Substituting the given values, we get:
[tex]ab^2[/tex] =[tex]6^2 + 6^2[/tex] - 2(6)(6) cos((180° - x)/2)
Simplifying, we get:
[tex]ab^2[/tex] = 72 - 72 cos((180° - x)/2)
Taking the square root of both sides, we get:
ab = √(72 - 72 cos((180° - x)/2))
Now we can calculate the area of triangle abc:
Area of triangle abc = (1/2)ab(bc)sin((180° - x)/2)
Substituting the given values, we get:
Area of triangle abc = (1/2)(√(72 - 72 cos((180° - x)/2)))(6)(sin((180° - x)/2))
Finally, we can subtract the area of triangle abc from the area of sector acb:
Area of shaded region = Area of sector acb - Area of triangle abc
Area of shaded region = (540x/π) - (1/2)(√(72 - 72 cos((180° - x)/2)))(6)(sin((180° - x)/2))
Approximating with x = 1.5 radians (which is approximately 86°), we get:
Area of entire circle ≈ 113.1 square units
Area of sector acb ≈ 283.5 square units
Thus, the Area of shaded region ≈ 95.2 square units.

Water has the ability to store heat longer than other substances. What benefit does this property of water provide to organisms?
Answer:

A rectangle’s length is 2 units more than twice its width. Its area is 40 square units. The equation w(2w + 2) = 40 can be used to find w, the width of the rectangle. What is the width of the rectangle? 4 units 5 units 10 units 12 units.
Given the value of the area, the width of the rectangle whose length is 2 units more than twice its width is 4 units
Option A) 4 units is the correct answer.
What is Rectangle?A rectangle is simply a 2-dimensional shape which has opposite sides equal to each other and all four angles are right angles.
Area of a rectangle is expressed as;
A = l × w
Where l is length and w is width
Given the data in the question;
Width of the rectangle = w unitsLength of the rectangle L = 2w + 2 unitsArea of the rectangle A = 40 units²Value of w = ?
We substitute our given values into the expression above.
A = l × w
40 = (2w + 2) × w
w( 2w + 2 ) = 40
2w² + 2w = 40
2w² + 2w - 40 = 0
divide through by 2
w² + w - 20 = 0
Using the quadratic formula;
x = (-b±√(b² - 4ac)) / (2a)
a = 1
b = 1
c = -20
w = (-1±√(1² - ( 4× 1 × -20 ))) / (2×1)
w = (-1±√(1 + 80)) / (2)
w = (-1±√(81)) / 2
w = (-1 ± 9) / 2
Hence
w = (-1 + 9) / 2 or (-1 - 9) / 2
w = 8/2 or -10/2
w = 4 or -5
But the width the rectangle cannot be a negative number.

The balloon ascends to an altitude of 20 km , where the pressure is 76. 0 mmhg and the temperature is − 50. ∘c. What is the new volume, v2 , of the balloon in liters, assuming it doesn't break or leak?
The new volume, v2, of the balloon in liters, assuming it doesn't break or leak, is 38.0546 L. To perform the calculation we will use the Boyle-Gay-Lussac law gas equation.
What is the Boyle-Gay-Lussac law?It is shown that the volume of the gas is inversely proportional to its pressure, while its volume is directly proportional to its temperature and constant pressure.
P1 x V1/T1 = P2 x V2/T2P1= Initial gas pressure
V1= Initial gas volume
P2= Final gas pressure
V2= Final volume of gas
T1= Initial gas temperature (Kelvin)
T2= Final gas temperature
Substituting the values in the formula, we have:
