Answer:

1. b ∈ B 2. ∀ a ∈ N; 2a ∈ Z 3. N ⊂ Z ⊂ Q ⊂ R 4. J ≤ J⁻¹ : J ∈ Z⁻

Step-by-step explanation:

1. Let b be the number and B be the set, so mathematically, it is written as

b ∈ B.

2. Let  a be an element of natural number N and 2a be an even number. Since 2a is in the set of integers Z, we write

∀ a ∈ N; 2a ∈ Z

3. Let N represent the set of natural numbers, Z represent the set of integers, Q represent the set of rational numbers, and R represent the set of rational numbers.

Since each set is a subset of the latter set, we write

N ⊂ Z ⊂ Q ⊂ R .

4. Let J be the negative integer which is an element if negative integers. Let the set of negative integers be represented by Z⁻. Since J is less than or equal to its inverse, we write

J ≤ J⁻¹ : J ∈ Z⁻

The probability of rolling a 1 with the first die and a 5 with the second die is P(A ∩ B) = (1/6) x (1/6) = 1/36.

The probability of rolling a 1 with the first die and a 5 with the second die can be calculated using the joint probability formula. The joint probability formula is P(A ∩ B) = P(A) x P(B|A). In this case, A is rolling a 1 with the first die and B is rolling a 5 with the second die. P(A) is the probability of rolling a 1 with the first die, which is 1/6. P(B|A) is the probability of rolling a 5 with the second die given that a 1 was rolled with the first die, which is also 1/6. Therefore, the probability of rolling a 1 with the first die and a 5 with the second die is P(A ∩ B) = (1/6) x (1/6) = 1/36.

Right triangles are triangles having one right angle, which means they have two perpendicular sides. They were historically referred to as right triangles. Trigonometry's fundamental concept is the connection between a right triangle's sides and the other angles. The term "right triangle" refers to a triangle with an interior angle of 90 degrees. The hypotenuse, which is also the longest side of a right triangle, is opposite the right angle, and the height and base are its two arms.

Answer:

Step-by-step explanation:

Given the coordinate points (6, -3) and (7, -10), we are to find the equation of a line passing through this two points;

The standard equation of a line is y = mx+c

m is the slope

c is the intercept

Get the slope;

m = Δy/Δx = y2-y1/x2-x1

m = -10-(-3)/7-6

m = -10+3/1

m = -7

Get the intercept;

Substitute the point (6, -3) and m = -7 into the expression y = mx+c

-3 = -7(6)+c

-3 = -42 + c

c = -3 + 42

c = 39

Get the required equation by substituting m = -7 and c= 39 into the equation y = mx+c

y = -7x + 39

Hence the required equation is y = -7x + 39

The least number of trips that Ava must make in order to deliver 250 cartons of books is 10 trips.

The least number of trips that Ava must make in order to deliver 250 cartons of books can be found by dividing the total number of cartons by the number of cartons that her car can hold per trip.

This can be written as:
Least number of trips = Total number of cartons / Number of cartons per trip

Substituting the given values into the equation, we get:
Least number of trips = 250 cartons / 26 cartons
Least number of trips = 9.62

Since Ava cannot make a fraction of a trip, we need to round up to the nearest whole number. Therefore, the least number of trips that Ava must make in order to deliver 250 cartons of books is 10.

Answer: the answer is 21

Step-by-step explanation:

If one angle measures 170°, and another angle measures (6k + 44)° and both are vertical angles that means the second angle should be the same as the first angle.

Vertical angles are congruent meaning they have an equal measure.

Now we have to find k

(6k + 44) = 170

subtract 44 - 44 and 170 - 44

(6k) = 126

divide 6 by 6, that leaves with just k on the left.

126 divided by 6  equals to 21

k = 21

The focus is the point inside a parabola that helps determine the shape of the curve.

A parabola is an equation of a curve, such that any point on the curve is equidistant from a fixed point called the focus and a fixed line called the directrix of the parabola.

The equation of a parabola:

y = a(x - h)² + k

We have,

A parabola is a type of curve that is formed when a plane intersects a cone at an angle that is parallel to one of the cone's sides.

One of the key defining features of a parabola is that all points on the curve are equidistant from a fixed point, known as the focus, and a fixed line, known as the directrix.

The focus is located inside the parabola, and its distance from the directrix is equal to the distance from any point on the parabola to the directrix.

This property allows us to use the focus and directrix to determine the shape and location of the parabola.

Thus,

The focus is the point inside a parabola that helps determine the shape of the curve.

The graph will generally exhibit a local maximum at x = 2 and local minima at x = -1 and x = -4

To determine the local maxima and minima of the function f(x) = (x-2)(x+1)(x+4), we can analyze the derivative f'(x). By setting f'(x) equal to zero and solving for x, we can find the critical points of f. The intervals of increase and decrease can be determined by examining the sign of f'(x) in different intervals. Sketching a graph of f can provide a visual representation of its behavior, but it's important to note that the specific shape of the graph may vary.

To find the critical points of f(x), we set f'(x) = 0 and solve for x. In this case, f'(x) = (x-2)(x+1)(x+4). Setting this equal to zero, we find that the critical points are x = 2, x = -1, and x = -4. These are the points where f(x) may have local maxima or minima.

To determine the intervals of increase and decrease, we can examine the sign of f'(x) in different intervals. We can choose test points within each interval and evaluate f'(x) to determine its sign. For example, in the interval (-∞, -4), we can choose x = -5 as a test point. Evaluating f'(-5), we find that f'(-5) < 0, indicating that f(x) is decreasing in this interval. By applying a similar process to the other intervals (-4, -1) and (-1, 2), we can determine the intervals of increase and decrease for f(x).

Sketching a graph of f(x) can help visualize the behavior of the function. However, it's important to note that the specific shape of the graph may vary. The graph will generally exhibit a local maximum at x = 2 and local minima at x = -1 and x = -4, but the curvature and overall shape of the graph will depend on factors such as the scale of the axes and the positioning of the critical points.

The common sum is 18 as "the numbers from 1 to 8 are placed at the vertices of a cube in such a manner that the sum of the four numbers on each face is the same".

A summation, also known as a sum, is the outcome of adding two or more numbers or quantities. There are always an even number of terms in a summation. There could be only two terms, or there could be one hundred, thousand, or a million. The outcome or conclusion we arrive at when we add two or more numbers is known as the SUM. Addends are the numbers that are added.

Here,

The sum of the numbers on one face of the cube is equal to the sum of the numbers on the opposite face of the cube; these 8 numbers represent all of the vertices of the cube.

The alternative hypothesis in this case is that the variance of the population is significantly greater than 0.003. Therefore, the correct answer is option A, S^2>0.003.

The variance is a term used in statistics that refers to how far the numbers in a data set are spread out. A set of numbers with a large variance has a wide distribution, while a set with a small variance has a narrow distribution.

The formula for the variance is as follows:S² = ∑(X - μ)² / Nwhere:∑ = the sum ofX = each individual data pointμ = the population meanN = the number of data points in the population. The null hypothesis in this case would be that the variance of the population is not significantly different from 0.003.
