In hypothesis testing, the null hypothesis (H0) and the alternative hypothesis (Ha) are used to assess the validity of a claim or statement about a population parameter.

Here are the answers to the given questions:

12. The null and alternative hypotheses divide all possibilities into:

b. Two non-overlapping sets

The null hypothesis and the alternative hypothesis are mutually exclusive and collectively exhaustive.

They represent two distinct possibilities or explanations regarding the population parameter being tested.

These sets do not overlap, meaning that an observation or outcome can only fall into one of these two categories.

13. Which of the following is true of the null and alternative hypotheses?

d. It is possible for neither hypothesis to be true

In hypothesis testing, the null hypothesis represents the default position or the status quo. It assumes that there is no significant difference or effect present in the population.

The alternative hypothesis, on the other hand, contradicts the null hypothesis and suggests that there is a significant difference or effect.

It is important to note that the null hypothesis is either rejected or failed to be rejected based on the evidence provided by the data.

The alternative hypothesis is not proven or accepted; instead, it is typically accepted by default when the null hypothesis is rejected.

Therefore, it is possible for neither hypothesis to be true if there is insufficient evidence to support the rejection of the null hypothesis. In such cases, no strong conclusion can be made based on the available evidence.

Answer:

Answer is 71.95°

Step-by-step explanation:

Cosine formula is

a^2=b^2+c^2-2bc(cosA)

cos A =b^2+c^2-a^2/2bc

if a= 119,b=94,c=173

cos A=94^2+173^2-119^2/2(94*173)

=8836+29,929-14,161/2(16,262)

=38765-14,161/32,524

=24604/32,524

=0.7564

cos A=0.7564

cos^-1=40.85°.that's for angle A.

Using the same formula

B=31.1°

C=180-(40.85+31.1)

C=180-71.95

C=108.05

Since angle on a straight line is 180

therefore x is 71.95

The function which describes the amount in dollars Emile has saved after t weeks is given by, A(t) = 30 + 15(t - 1).

Hence the correct option is (B).

The variable which represents the number of weeks is 't' and the amount saved after t weeks represented by 'A'.

Since from the table we can see that for every extra 1 unit of 't' there is an increase of $15 in 'A' in same rate.

From the table we can conclude that the relation between A and t is Linear.

So the function rule which describes the relation between them better, let that be, A = p*t + q, where p and q are arbitrary constants.

From the table we can see that, when t = 1 then A = 30. So,

30 = p*1 + q

p + q = 30 ................ (i)

Again when t = 6 then A = 105, so

6p + q = 105 ................... (ii)

Subtracting equation (i) from equation (ii) we get,

6p + q - p - q = 105 - 30

5p = 75

p = 75/5

p = 15

Substituting p = 15 in equation (i) we get,

15 + q = 30

q = 30 - 15 = 15

So the function which describes the amount saved A after t weeks is given by,

A(t) = 15t + 15

A(t) = 15t + 30 - 15

A(t) = 30 + 15(t - 1)

Hence the correct option is (B).

The translated vertices, substitute the values into the area formula:
  Area = \(1/2 * |0(y2 - y3) + (x2 - x1)(y3 - y1) + (x3 - x1)(y1 - y2)|\)

To find the area of triangle R, we can use the formula:

Area =\(1/2 * |x1(y2 - y3) + x2(y3 - y1) + x3(y1 - y2)|\)

Here's how you can apply the hint and solve the problem step-by-step:

The problem involves proving that the area of a triangle with arbitrary vertices can be calculated using a determinant of a matrix. After placing the vertices coordinates into a 3x3 matrix, we find that the area is half the absolute value of the determinant of this matrix.

The question is asking to prove that the area of a triangle with vertices at (.x1; y1/), (.x2; y2/), and (.x3; y3/) can be calculated using the determinant of a matrix. The first step in the proof is to arrange the coordinates of the vertices into a 3x3 matrix.

The determinant of this matrix will give 2 times the area of the triangle formed by these vertices. The next step is to calculate the determinant of this matrix. This can be done by expanding along a row or a column and making use of the property det(A) = -det(A^transpose).

Doing the calculations, we get that the area of the triangle is half the absolute value of the determinant of the matrix, which confirms the statement.

The event that the card is a queen, denoted as e, and the event that the card is a heart, denoted by f, are not independent.

Independent events are events where the occurrence or outcome of one event does not affect or influence the occurrence or outcome of another event. In other words, the outcome of one event has no effect on the probability of the other event happening. For example, flipping a coin and rolling a dice are independent events, because the outcome of one event (e.g., heads on a coin flip) does not affect the outcome of the other event (e.g., rolling a six on a dice).

The event "the card is a queen" reduces the number of cards in the deck, while the event "the card is a heart" also reduces the number of cards in the deck. The intersection of these two events, "the card is a queen of hearts," is a smaller set of cards than either event individually, so these events are dependent.

A table can be represented with a linear function equation as y = mx + b, where m is the slope and b is the y-intercept.

Assuming we have a table of values as shown in the image attached below, to write an equation of linear function for the table, do the following:

Pick two pairs of values, say, (1, 5) and (2, 25) and find the slope (m):

Slope (m) = change in y / change in x = (25 - 5)/(2 - 1)

Slope (m) = 20

Find the y-intercept (b) by substituting (x, y) = (1, 5) and m = 20 into y = mx + b:

5 = 20(1) + b

5 = 20 + b

5 - 20 = b

-15 = b

b = -15

Write the equation of the linear function by substituting m = 20 and b = -15 into y = mx + b:

The number of hours Natalie worked babysitting last week is 6hrs and the number of hours she worked landscaping last week is 2 hrs.

Let x be the number of hours Natalie worked babysitting and y be the number of hours she worked landscaping. Then, the total earnings were 11x + 10y = $86.

Also, x = 3y, because she worked 3 times as many hours babysitting as she did landscaping.

Substitute x = 3y into the first equation:

11(3y) + 10y = $86

Expanding the first term we get,

33y + 10y = $86

Combining terms,

43y = $86

Dividing both sides by 43 we get,

y = $2

So, Natalie worked y = 2 hours of landscaping.

To find the number of hours she worked babysitting, substitute y = 2 into x = 3y as follows -

x = 3(2) = 6

So Natalie worked x = 6 hours babysitting.

The equation \(x^2 + y^2 + z^2 = 8006\) has no solutions because 8006 is congruent to 6 modulo 8, which cannot be obtained as a sum of three squares; and there are infinitely many positive integers that cannot be expressed as the sum of three squares by Legendre's three-square theorem.

To prove that the equation \(n x^2 + y^2 + z^2 = 8006\) has no solutions, we can use the hint and work modulo 8.

Note that any perfect square is congruent to 0, 1, or 4 modulo 8. Therefore, the sum of three perfect squares can only be congruent to 0, 1, 2, or 3 modulo 8.

However, 8006 is congruent to 6 modulo 8, which is not possible to obtain as a sum of three squares.

Hence, the equation\(x^2 + y^2 + z^2 = 8006\) has no solutions.

To demonstrate that there are infinitely many positive integers that cannot be expressed as the sum of three squares, we can use the theory of modular arithmetic and Legendre's three-square theorem, which states that an integer n can be expressed as the sum of three squares if and only if n is not of the form \(4^a(8b+7)\) for non-negative integers a and b.

Suppose there are only finitely many positive integers that cannot be expressed as the sum of three squares, and let N be the largest such integer.

By Legendre's theorem, N must be of the form \(4^a(8b+7)\) for some non-negative integers a and b. Note that N is not a perfect square, since any perfect square can be expressed as the sum of two squares.

Let p be a prime factor of N, and consider the equation \(x^2 + y^2 + z^2 = p.\)  This equation has a solution by Lagrange's four-square theorem, which states that any positive integer can be expressed as the sum of four squares.

Since p is a prime factor of N, it follows that p is not of the form \(4^a(8b+7),\) and hence p can be expressed as the sum of three squares. Therefore, we have found a positive integer (p) that cannot be expressed as the sum of three squares, contradicting the assumption that N is the largest such integer.

Hence, there must be infinitely many positive integers that cannot be expressed as the sum of three squares.

The equation x² + y² + z² = 8006 has no solution because 8006 cannot be expressed as a sum of 3 perfect squares

From the question, we have the following parameters that can be used in our computation:

x² + y² + z² = 8006

To do this, we make use of modulo 8

So, we have

x² + y² + z² = 8006 mod (8)

The perfect squares less than or equal to 8 are 0, 1 and 4

So, we have

n ≡ 0 (mod 8) ⟹ n²  ≡ 0² ≡ 0 (mod 8)

n ≡ 1 (mod 8) ⟹ n²  ≡ 1² ≡ 1 (mod 8)

n ≡ 2 (mod 8) ⟹ n²  ≡ 2² ≡ 4 (mod 8)

n ≡ 3 (mod 8) ⟹ n²  ≡ 3² ≡ 1 (mod 8)

n ≡ 4 (mod 8) ⟹ n²  ≡ 4² ≡ 0 (mod 8)

n ≡ 5 (mod 8) ⟹ n²  ≡ 5² ≡ 1 (mod 8)

n ≡ 6 (mod 8) ⟹ n²  ≡ 6² ≡ 4 (mod 8)

n ≡ 7 (mod 8) ⟹ n²  ≡ 7² ≡ 1 (mod 8)

The above means that no 3 values chosen from {0, 1, 4} will add up to 7 (mod 8).

This also means that 8006 ≡ 7(mod 8).

So, it cannot be expressed as a sum of 3 perfect squares.
