There are 87 possible outcomes that contain at least three heads when a coin is flipped 9 times.

When a coin is flipped nine times, there are 512 possible outcomes, or 29. Using the equation:

P (At least one head) = 1 - 0.5n,

where n is the total number of flips, we can determine the number of outcomes that contain at least three heads.

Therefore, P (At least three heads) = 1 - P (No heads) - P (One head) - P (Two heads)

= 1 - (0.5)⁹ - 9(0.5)⁹ + 36(0.5)⁹

= 0.1718751.

The formula used to calculate the number of possible outcomes that contain at least three heads is C(9,3) + C(9,4) + C(9,5) + C(9,6) + C(9,7) + C(9,8) + C(9,9),

where C(n,r) denotes the variety of options for selecting item(s) r from a set of item(s) n.

The correct option is B) one minus the probability of not rejecting a false null hypothesis.

The power of a statistical test refers to its ability to correctly reject a false null hypothesis. It is the probability of rejecting a false null hypothesis, or in other words, the probability of correctly concluding that there is an effect or difference when one truly exists.

Option A) "the probability of rejecting a true null hypothesis" is incorrect because the power of a test is not related to the probability of rejecting a true null hypothesis. The power is focused on the ability to detect false null hypotheses.

Option C) "Type II error" is incorrect because Type II error refers to failing to reject a false null hypothesis. It is the error of accepting a false null hypothesis or failing to detect an effect or difference when one truly exists.

Option D) "Type I error" is also incorrect because Type I error refers to rejecting a true null hypothesis, which is not directly related to the power of a test.

Therefore, the correct option is B) one minus the probability of not rejecting a false null hypothesis, which represents the power of a test.

The charge on the line segment extending from (2,1,5) to (4,3,6) is determined by finding the line integral of the electric field along that line.

This line integral can be calculated by parameterizing the line segment and computing the integral using the formula:∫_a^b E·dswhere E is the electric field, s is the position vector along the line, and a and b are the starting and ending points of the line.

To parameterize the line segment, we can use the equation:r(t)=(2,1,5)+t(2,2,1)where 0 ≤ t ≤ 1. This gives us a point on the line for each value of t, and the vector (2,2,1) gives us the direction of the line. We can then calculate the electric field at each point along the line .

(a) The coordinates after Rotation of 270° counterclockwise are W(5, -1), X(5, -7), Y(2, -7) and Z(2, -1).

(b) The coordinates after translation: (x, y) =(x-7, y + 3) are W(-6, 8), X(0, 8), Y(0, 5) and Z(-6, 5).

What is Rotation and Translation of coordinates ?

A rotation is any movement within a specific space that keeps at least one point. A rigid body's motion around a fixed point is one example of what it can be used to explain.

Every point in a figure, shape, or space is moved by the same amount and in the same direction by a translation, which is a geometric transformation.

Since the Rotation of Rectangle is 270° counterclockwise, it will shift the rectangle from 1st Quadrant to 4th Quadrant with transition from (x, y) to   (y, -x).

So, the coordinates after rotation of 270° counterclockwise are :

W(1, 5) ⇒ W(5, -1)

X(7, 5) ⇒X(5, -7)

Y(7, 2) ⇒Y(2, -7)

Z(1, 2) ⇒Z(2, -1)

Similarly, The coordinates after translation of (x, y) ⇒ (x-7, y+3 )

W(1, 5) ⇒ W(1-7, 5+3) = W(-6, 8)

X(7, 5) ⇒X(7-7, 5+3) = X(0, 8)

Y(7, 2) ⇒Y(7-7, 2+3) =Y(0, 5)

Using the Counting the faces of two dice,

the atleast 17 number of faces are possible on the combination of two dice.

First, we have to count the favorable cases,

We know both dice have atleast 6 faces.

It gives 6 favorable cases for a sum of 7.

If we can count them if mean even if dice had more than 6 faces, will matter of for sum of 7.

Now, the mean, we need 6× 4/3=8 (favorable cases for the sum of 10)

If we count 3 favorable cases for each having 6 faces.

For more than 9 faces on a dice matter give the denominator (sample space) are the same for both sum of 7 and the sum of 10, and the probability of one is in proportion to the other.

It mean, additional 5 cases must be ( 7,2), (2,7), (8,2), (2,8) ,(9,1)

According to the question and after using the Pythagorean theorem the length of one side of the roof is 7.416 metres.

The Pythagorean Theorem is a mathematical formula used to determine the length of the sides of a right triangle. It is named after the Greek mathematician Pythagoras, who is credited with discovering the formula in the 6th century BC. The theorem states that the sum of the squares of the two shorter sides of the triangle is equal to the square of the hypotenuse (the longest side of the triangle). In equation form, it is expressed as a² + b² = c², where a and b are the lengths of the two shorter sides of the triangle and c is the length of the hypotenuse.

We know that the hypotenuse is 8 metres (the width of the shed) and the two shorter sides are 3 metres (the height of the walls) and y (the length of the side of the roof).
Therefore, using the Pythagorean theorem, we have:
3² + y² = 8²
9 + y² = 64
y² = 55
y = √55
y = 7.416 metres
Therefore, the length of one side of the roof is 7.416 metres.

The required  cost of each shirt is $21.28.

A mathematical statement known as an equation is made up of two expressions joined together by the equal symbol. A formula would be 3x - 5 = 16, for instance. When this equation is solved, we discover that the value of the quantity x is 7.

The total cost of 3 identical shirts, including shipping, is $71.83. So we can write the equation as:

3s + 7.99 = 71.83

To solve for the cost of each shirt, we need to isolate the variable "s" on one side of the equation. We can start by subtracting 7.99 from both sides:

3s = 63.84

Then, we can divide both sides by 3:

To maximize profits, the firm should produce a quantity of goods x = 5 and y = 10, based on the cost function and price constraints.

To maximize profits, the firm needs to find the quantities of goods x and y that will yield the highest profit. The profit function can be defined as the revenue minus the cost. Revenue is calculated by multiplying the quantity of each good produced with their respective prices, while the cost function is given as C(x, y) = 10x + xy + 10y.

The firm is committed to delivering a total of 15 units, which can be expressed as x + y = 15. To determine the optimal production quantities, we need to maximize the profit function subject to this constraint.

By substituting the price expressions Ps = 50 - x + y and Py = 50 - x + y into the profit function, we obtain the profit equation. To find the maximum profit, we can take the partial derivatives of the profit equation with respect to x and y, set them equal to zero, and solve the resulting system of equations.

Declan's reasoning does make sense. This is because 3/4 and 1/2 have the same denominator, and 3/4 is a larger fraction than 1/2.

Therefore, it is reasonable to assume that 3/4 is greater than 6/12 because 6/12 simplifies to 1/2. Simplifying fractions means dividing the numerator and denominator by the same number, in this case, 6 is divisible by 2, so we can reduce the fraction to 1/2.

So, Declan is correct in his reasoning that 3/4 is greater than 6/12. It is important to understand the relationship between fractions and their denominators to make such comparisons accurately.

3/4 = 9/12

1/2 = 6/12

6/12 = 6/12

Since 9/12 (which is equivalent to 3/4) is greater than 6/12 (which is equivalent to 1/2), we can say that 3/4 is indeed greater than 6/12.

Step-by-step explanation:

The measure of angle COA is 160 degrees. (option c)

In triangle ACO, we know that AC and CO are equal because they are radii of the same circle. Therefore, angle ACO and angle CAO must be equal.

We also know that the sum of the angles in a triangle is always 180 degrees, so we can write:

angle ACO + angle CAO + angle COA = 180 degrees

We can substitute angle ACO for angle CAO because they are equal, giving us:

2(angle ACO) + angle COA = 180 degrees

Solving for angle ACO, we get:

2(angle ACO) = 180 degrees - angle COA

angle ACO = (180 degrees - angle COA)/2

Now we can substitute this expression for angle ACO into our earlier equation for angle COA:

angle COA = angle AOC + angle ACO

angle COA = 80 degrees + [(180 degrees - angle COA)/2]

We can simplify this equation by multiplying both sides by 2:

2(angle COA) = 160 degrees + (180 degrees - angle COA)

Distributing the 2 on the left side, we get:

2angle COA = 160 degrees + 180 degrees - angle COA

Combining like terms, we get:

3angle COA = 480 degrees

Dividing both sides by 3, we get:

angle COA = 160 degrees (rounded to two decimal places)
