Use the table in the book to find the P-value rounded to at least 4 decimal places.
It is not possible to find the exact P-value rounded to at least 4 decimal places by using tables, as the P-value is a continuous variable and tables only give a range of values containing the P-value.
The probability that you would have discovered a specific collection of observations if the null hypothesis were true is expressed as a number called the p value, which is determined from a statistical test.
In order to determine whether to reject the null hypothesis, P values are utilised in hypothesis testing. You are more inclined to reject the null hypothesis the smaller the p value.

Which fraction is equivalent to 1/2? Use the number line to help answer the question
Answer:
4/8
Step-by-step explanation:
-2x+20y=-18
8x+10y=-18
Answer:
x = -1
y = -1
Step-by-step explanation:
This is a system of equations- the set up of the problem lends well to using the elimination method. There are always many ways of solving a system of equations, both in methods and different strategies within each method. The problem isn't necessarily complete but I can assume you're being asked to solve for x and y values.
divide the first equation by -2. this means we can use elimination to cancel out the y value, and is also our simplest option (rather than multiplying the second equation by -2.
-2x + 20y = -18 --> x - 10y = 9
x - 10y = 9
8x + 10y = -18
Using the elimination method to essentially add the parts of the equations together, this comes out to 9x = -9 , meaning x = -1 .
We can then return to our original equations, and substitute -1 for x (either equation will work, but the second one is simpler and therefore the better option).
8 (-1) +10y = -18
-8 + 10y = -18
10y = -10
y = -1
CHECKING
Substitute both x and y values back into the original equations to check them. the sides should be equal if our values are correct.
-2 (-1) + 20 (-1) = -18
Our first equation works: 2 - 20 = -18
8 (-1) + 10 (-1) = -18
The second equation works as well: -8-10= -18

decide whether the function is a polynomial function. If so right it in standard form and state it’s degree type in leading coefficient if so write it in standard form and state its degree type in leading coefficient P(x)=-3x^2+10-4x
For the polynomial p(x) = -3x² - 4x + 10, the degree is 2 and the leading coefficient is -3
What is an polynomial?Polynomials consist of exponents of variables and numbers forming an equation using operations of addition and subtraction.
Polynomial is an expression composed of variables, constants and exponents combined using mathematical operations such as addition, subtraction, multiplication
Given the polynomial:
p(x) = -3x² + 10 - 4x
Rewriting the polynomial in standard form is done by rearranging based on exponents. Hence:
p(x) = -3x² - 4x + 10
The degree is 2 (x²) and the leading coefficient is -3(-3x²)

The measures of the three angles of a triangle are in the ratio of 1:2:2. Find their measures.
Answer:
36°, 72°, and 72°
Step-by-step explanation:
The interior angles of a triangle will always add to 180°.
Let's say the smallest angle is x, then the other two angles are both 2x.
x+2x+2x=180
5x=180
x=36
If our angles are x, 2x, and 2x, and we know x is 36, then the answer is:
36°, (2*36)°, and (2*36)°, which equals
36°, 72°, and 72°
Check: 36+72+72=180

Select the interval where the graph h is negative.
Answer: C
Step-by-step explanation:
Based on the graph, we know that it is negative if it is under the x-axis. It is also indicated by the negative labels.
A: incorrect
Looking at choice A, it says the interval is from -3<x<-2. This means we have to find x=-3 and x=-2. On the graph, that interval is above the x-axis, so it is positive, not negative.
B: incorrect
Looking at choice B, it says the interval is from 2<x<3. This means we have to find x=2 and x=3. On the graph, that interval is above the x-axis, so it is positive, not negative.
C: correct
Looking at choice C, it says the interval is from 4<x<5. This means we have to find x=4 and x=5. On the graph, that interval is under the x-axis, so it is negative.
Therefore, C is the correct answer.

The endpoints of a line segment AB are (1, -6) and (5, -6). The equation of a line BC is
y=x-11. Is triangle ABC a right triangle? Justify your answer.
No, triangle ABC is not a right triangle. The equation of a line BC "y=x-11" is a line with slope of 1, which means it has an angle of 45 degrees with respect to the x-axis. The segment AB has a slope of 0, which means it is parallel to the x-axis. A right triangle's legs must be perpendicular, therefore a line with a slope of 1 and a line with a slope of 0 cannot be the legs of a right triangle.
A RIGHT TRIANGLEA right triangle is a triangle in which one of the angles is 90 degrees. In order for a triangle to be a right triangle, the two sides (or legs) that form the 90-degree angle must be perpendicular to each other. Perpendicular lines have slopes that are negative reciprocals of each other.
In this case, the equation of the line segment AB is "y = -6", which means it is parallel to the x-axis. The slope of a line parallel to the x-axis is 0. On the other hand, the equation of the line BC is "y = x - 11", which means it has a slope of 1. A slope of 1 means that the line is at a 45 degree angle with respect to the x-axis.
Since the slopes of the two lines are not negative reciprocals of each other (0 and 1), the legs of the triangle cannot be perpendicular. Therefore, triangle ABC cannot be a right triangle.

A stack of identical 8-centimeter-by-10-centimeter rectangular playing cards is sitting on a table. The stack is 1 centimeter high and has a volume of 80 cubic centimeters. The table is bumped and the stack of cards is shifted so that the stack is no longer a right rectangular prism, but all of the cards are still part of the stack.
Which of the following statements are true of the shifted stack of cards? Select all that apply.
A) The shifted stack of cards has a volume of 80 cubic centimeters because it has the same base area and height.
B) The area of a card at any location in the stack remains the same.
C) The width of the stack from the leftmost edge to the rightmost edge will remain 10 centimeters because the volume is the same.
D) Cavalieri’s principle cannot be applied to the volume of the stack because the stack is a rectangular prism instead of a cylinder.

Approximately 3.4% of Americans are vegetarian. If we ask a random sample of 36 people, what is the probability that exactly 4 of them are vegetarian?
Answer:
0
Step-by-step explanation:
Given: 3.4% of Americans are vegetarian.
sample size = 36 people
Therefore, 3.4% of 36 = 1.224.
Hence, out of 36 people only 1.224 people which is approximately 1 is vegetarian.
So, the probability of exactly 4 people being vegetarian out of 36 people would be zero.
As out of 36 only 1 was vegetarian.
Hence, the correct answer would be 0

To prove that ΔABC is isosceles.
Properties of an isosceles triangle.An isosceles triangle is a type of triangle in which the length of its two sides, and measure of its two internal angles are equal. When a bisector of an angle is drawn to one of the internal angles of the triangle, two congruent triangles of corresponding properties are produced.
To prove that ΔABC is isosceles, we have:
<CAD ≅ <BAD (definition of an angle bisector)
CD ≅ BD (definition of a midpoint)
AC ≅ AB (congruent sides of an isosceles)
<ACD ≅ <ABD (congruent internal angles of an isosceles)
<ADC ≅ <ADB (definition of right angle)

Answer:
The value of x is 2/7 or 0.285
Step-by-step explanation:
Here, we will make equivalent expressions in the equation that all have equal bases.
6²⁽⁶ˣ⁻¹⁾ = 6⁵ˣ
Since, The bases are the same i.e., 6. So, exponent are also same
2(6x - 1) = 5x
Solve for x
12x - 2 = 5x
12x - 5x - 2 + 2 = 5x - 5x + 2
7x = 2
7x/7 = 2/7
x = 2/7 = 0.285
Thus, The value of x is 2/7 or 0.285
For verification
36⁶ˣ⁻¹ = 6⁵ˣ
36⁶⁽⁰°²⁸⁵⁾ ⁻ ¹ = 6⁵⁽⁰°²⁸⁵⁾
36¹°⁷¹ ⁻ ¹ = 6¹°⁴²⁵
36⁰°⁷¹ = 6¹°⁴²⁵
