The length of side b is 56m, angle A is 45°, and angle C is 67°.

In the given triangle with side lengths a = 74m, b ≈ 56m, and c = 36m, the length of side b is approximately 56m.

To solve the triangle, we can use the Law of Cosines and the fact that the sum of angles in a triangle is 180 degrees. Given angle B = 67°51', we have:

Using the Law of Cosines, we have:

b² = a² + c² - 2ac * cos(B)

Substituting the known values:

b² = 74² + 36² - 2 * 74 * 36 * cos(67°51')

Calculating the value of b:

b ≈ √(74² + 36² - 2 * 74 * 36 * cos(67°51'))

b ≈ 55.92m (rounded to the nearest whole number, b ≈ 56m)

Using the Law of Cosines again, we have:

cos(A) = (b² + c² - a²) / (2 * b * c)

Substituting the known values:

cos(A) = (56² + 36² - 74²) / (2 * 56 * 36)

Calculating the value of A:

A = cos⁻¹((56² + 36² - 74²) / (2 * 56 * 36))

A ≈ 45° (rounded to the nearest whole number)

Using the fact that the sum of angles in a triangle is 180 degrees:

C = 180° - A - B

Substituting the known values:

C ≈ 180° - 45° - 67°51'

Calculating the value of C:

C ≈ 67°9' (rounded to the nearest whole number, C ≈ 67°)

Therefore, in the given triangle, the length of side b is approximately 56m, angle A is approximately 45°, and angle C is approximately 67°.

Thus, the possible subsets of the set a = {a, b, c, d, e} using both elements a and b are: {a, b}, {a, b, c}, and {a, b, d}.

To find all possible subsets of the set a = {a, b, c, d, e} using both elements a and b, we need to consider all the possible combinations of these two elements with the remaining elements in the set.

There are three possible subsets that we can create using both elements a and b:

1. {a, b} - This is the subset that contains only the elements a and b.
2. {a, b, c} - This subset contains the elements a and b, along with the third element c.
3. {a, b, d} - This subset contains the elements a and b, along with the fourth element d.

Note that we cannot create any more subsets using both elements a and b because we have already considered all the possible combinations with the remaining elements in the set.

In summary, the possible subsets of the set a = {a, b, c, d, e} using both elements a and b are: {a, b}, {a, b, c}, and {a, b, d}.

The frequency distribution provides the intervals and corresponding frequencies, but the values within each interval are not given. To calculate the 77th percentile using the given frequency distribution, we need to determine the measurement value that separates the lower 77% of the data from the higher 23%.

We need to make an assumption about the distribution of the data within each interval. For simplicity, we will assume that the values within each interval are uniformly distributed.

To calculate the 77th percentile, we follow these steps:

Calculate the total frequency: Add up all the frequencies given in the table.

Determine the cumulative frequency: Calculate the cumulative frequency for each interval by adding up the frequencies starting from the first interval.

Find the interval containing the 77th percentile: Multiply the total frequency by 0.77 (77%) to obtain the desired percentile.

Interpolate to find the exact measurement value: Use linear interpolation to estimate the measurement value corresponding to the 77th percentile within the interval found in step 3.

By following these steps, we can calculate the 77th percentile using the given frequency distribution.

In Analysis of variance,  X (bar) is not affected by whether or not the population means are equal.

Analysis of variance  is a statistical method for examining differences in means. It consists of a number of statistical models and the accompanying estimating techniques (such as the "variation" within and between groups). Ronald Fisher, a statistician, created Analysis of variance. The rule of total variance, on which the Analysis of variance is based, divides the observed variance in a given variable into components owing to various causes of variation.

ANOVA generalizes the t-test beyond two means by offering a statistical test to determine if two or more population means are equal. In other words, the Analysis of variance is employed to determine whether two or more means differ from one another.

The required surface area of a rectangular container is 588cm² using a volume of 1,372 cm³.

The quantity of space enclosing a three-dimensional shape's exterior is its surface area.

In comparison to the definition of arc length for one-dimensional curves or the definition of surface area for polyhedra (i.e., objects with flat polygonal faces), where the surface area is equal to the sum of the areas of its faces, the mathematical definition of surface area in the presence of curved surfaces is significantly more complex.

The surface area of smooth surfaces, such as spheres, is determined using their representation as parametric surfaces.

Partial derivatives and double integration are used in this definition of surface area, which is based on infinitesimal calculus techniques.

So, we have the volume:

1,372 cm³

Then, h = 1372/s².

Now, calculate as follows:

4 s 1372/s^2 + s^2 = area

5488/s + s^2 = area

s^2 + 5488 (s^-1) = area    

2s - 5488 s^-2 = 0

5488 s^-2 = 2s

5488 = 2 s^3

2744 = s^3    

s =  14        

s * h * s = 1372    

Then, we will have: h = 7

Surface area = 14*14+4*7*14 = 196+4*7*14 = 588 cm²

Therefore, the required surface area of a rectangular container is 588cm² using a volume of 1,372 cm³.

Answer:

F = 53.1°

Step-by-step explanation:

When you consider F as your angle

cos F = adjacent / hypotaneous

or, cos F = EF/DF

We do not have DF right now,

so DF² = DE² + EF²

DF = √ (12² + 9²)

DF = 15

cos F = adjacent / hypotaneous

or, cos F = EF/DF

cos F = 9 / 15

F = cos ⁻¹ (9/15)

F = 53.1°

Step-by-step explanation:

By the Hypotenuse Leg theorem, we have proven that ΔPXA ≅ ΔQYA

From the question, we are to prove that ΔPXA ≅ ΔQYA

From the Hypotenuse Leg theorem which states that "two right triangles are congruent if the hypotenuse and one leg of one right triangle are congruent to the other right triangle's hypotenuse and leg side".

From the given information,

PX ⊥ XY

ΔPXA is right triangle with hypotenuse PA

Also,

QY ⊥ XY.

ΔQYA is right triangle with hypotenuse AQ

We have that A is the midpoint of PQ

∴ PA ≅ AQ

This means the hypotenuse of ΔPXA is congruent to the hypotenuse of ΔQYA

Also,

A is the midpoint of XY,

∴ XA ≅ AY

This means the legs of the right triangles are equal.

Hence, by the Hypotenuse Leg theorem, we have proven that ΔPXA ≅ ΔQYA

Question: In a sale, the price of a book is reduced by 25%. The price of the book in the sale is £12. Work out the original price of the book

Answer: £16

Step-by-step explanation:

To determine the original price of the book, we can use the fact that the sale price is 75% (100% - 25%) of the original price. Let's denote the original price as x.

75% of x = £12

To solve for x, we can set up the equation:

0.75x = £12

To isolate x, we divide both sides of the equation by 0.75:

x = £12 / 0.75

x = £16

Therefore, the original price of the book was £16.

When calculating S² pooled, each sample's estimate of population variance is weighted by its respective contribution to the total degrees of freedom. Therefore, the correct option is (c).

When conducting a hypothesis test for the difference between two population means, it is often necessary to estimate the common population variance. In this case, the pooled variance or S² pooled is used, which is a weighted average of the sample variances from each of the two samples. To calculate S² pooled, each sample's estimate of population variance is weighted by its respective contribution to the total degrees of freedom. The total degrees of freedom is equal to the sum of the degrees of freedom of each sample, which is n1 - 1 + n2 - 1 = n1 + n2 - 2. The weights are proportional to the degrees of freedom of each sample, so the weight for the first sample is (n1 - 1)/(n1 + n2 - 2) and the weight for the second sample is (n2 - 1)/(n1 + n2 - 2).

Therefore, S² pooled = [(n1 - 1)S1² + (n2 - 1)S2²]/(n1 + n2 - 2), where S1² and S2² are the sample variances of the two samples. The pooled standard deviation is then the square root of S² pooled.

In summary, S² pooled is the weighted average of the sample variances, where the weights are proportional to the degrees of freedom of each sample. The total degrees of freedom is equal to the sum of the degrees of freedom of each sample.

the length of the unknown side (side C) is 25 units.In a right triangle, the Pythagorean theorem states that the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

Given:
Side A = 15
Side B = 20

Let's denote the length of the unknown side as C. Applying the Pythagorean theorem, we have:

C^2 = A^2 + B^2

Substituting the given values:

C^2 = 15^2 + 20^2
C^2 = 225 + 400
