The height of the building, using similar triangles, is given by:

36 feet.

Similar triangles are two triangles that share these two features, which are listed as follows:

The second bullet point, regarding proportional side lengths, is especially relevant in the context of this problem, as a proportional relationship is built to find the height h of the building.

From the similar triangles, the equivalent side lengths are presented as follows:

Hence the proportional relationship that models this situation is presented as follows:

3/18 = 6/h.

Applying cross multiplication, the height of the building is obtained as follows:

3h = 18 x 6

h = 6 x 6 (simplifying by 3)

h = 36 feet.

The diagram is given by the image shown at the end of the answer.

By another pair of sides along with pair of angles we can prove that two triangles are congruent by ASA congruence postulate.

What is ASA Congruence Postulate?

A set of triangles can be proven to be congruent using the angle-side-angle rule.

According to the ASA rule, two triangles are congruent if their two included sides and two angles are the same as those of another triangle.

Using the ASA Congruence Postulate and by considering the following image,

∠ B = ∠ Q, ∠ C = ∠ R and sides between ∠B and ∠C , ∠Q and ∠ R are equal to each other.

i.e. BC= QR.

Hence, Δ ABC ≅ Δ PQR.

Answer:

$1.60

Step-by-step explanation:

12.73÷8 = 1.59125

(1.59 rounded is 1.60)

Answer:

  $1.59 per lb

Step-by-step explanation:

What is a "unit price" depends on the unit of interest. Unit price tags on the shelf in a store are supposed to aid a shopper in determining the best value. In the situation described here. possible unit prices are ...

  cost per bag

  cost per pound

__

Obviously, the cost per bag is ...

  ($12.73)/(1 bag) = $12.73 per bag

The cost per pound will be ...

  ($12.73)/(8 lb) = $1.59125 /lb ≈ $1.59 per lb

y = 7/8x shows a proportional relationship where 7/8 is the constant.

A proportional relationship is a type of relationship between two variables in which the ratio of their values is constant. This means that if one variable increases, the other variable will also increase in proportion to the first.

One way to identify a proportional relationship is to look for an equation that has the form y = kx, where y and x are the two variables and k is a constant value. This equation represents a direct proportion, in which the value of y is directly proportional to the value of x.

For example, if y represents the cost of a product and x represents the number of units of the product being purchased, the equation y = 2x could represent a direct proportion, where the cost of the product is $2 per unit.

Therefore, the equation, y = 7/8x is a proportional relationship.

The median age of the 120 people seated in the first five rows of the concert was 31.

Value is an important concept in economics and business. It is the worth of goods, services, or assets that is determined by the market or by an individual. It can be measured in terms of money, time, or effort. Value is also used to describe a person’s sense of worth or importance. Values can be seen as the principles, standards, or goals that guide an individual’s actions and decisions. Ultimately, value is subjective and is held by each person and can change over time.

The box and whisker plot provided by the sponsor shows the ages of the 120 people seated in the first five rows of the concert. The box and whisker plot shows a minimum value of 18, a maximum value of 45, a median of 31, a first quartile of 24, and a third quartile of 37.

Answer:

Step-by-step explanation:

12x15=180

(a) One ball is drawn at random from the urn and it is red, so the posterior distribution of X can be found using Bayes' theorem:

P(X = x | red) = P(red | X = x) * P(X = x) / P(red)

where P(X = x) is the prior probability of X being x, P(red | X = x) is the probability of getting a red ball given that X is x, and P(red) is the total probability of getting a red ball.

Since all possible values of X from 0 to 9 are equally likely, the prior probability of X being x is P(X = x) = 1/10 for x = 0, 1, 2, ..., 9.

The probability of getting a red ball given that X is x can be calculated using the hypergeometric distribution:

P(red | X = x) = (x choose 1) * (9-x choose 8-x) / (9 choose 1)

where (x choose k) is the number of combinations of x items taken k at a time.

The total probability of getting a red ball is:

P(red) = sum(P(red | X = x) * P(X = x)) for x = 0, 1, 2, ..., 9

Using these formulas, we can find the posterior distribution of X and the mean of X:

Posterior distribution of X:

P(X = x | red) = P(red | X = x) * P(X = x) / P(red)

Mean of X:

E(X | red) = sum(x * P(X = x | red)) for x = 0, 1, 2, ..., 9

(b) Now suppose that a second ball is drawn from the urn, without replacing the first, and it is green, so the posterior distribution of X can be found using Bayes' theorem again:

P(X = x | red, green) = P(green | X = x) * P(X = x | red) / P(green)

where P(X = x | red) is the posterior distribution of X from part (a), P(green | X = x) is the probability of getting a green ball given that X is x, and P(green) is the total probability of getting a green ball.

The probability of getting a green ball given that X is x can be calculated using the hypergeometric distribution:

P(green | X = x) = (9-x choose 1) * (x choose 8-x) / (9 choose 1)

The total probability of getting a green ball is:

P(green) = sum(P(green | X = x) * P(X = x | red)) for x = 0, 1, 2, ..., 9

Using these formulas, we can find the posterior distribution of X and the mean of X:

Posterior distribution of X:

P(X = x | red, green) = P(green | X = x) * P(X = x | red) / P(green)

Mean of X:

E(X | red, green) = sum(x * P(X = x | red, green)) for x = 0, 1, 2, ..., 9

The value of probability P (A or B) is,

P (A or B) = 19/34

We have to given that,

From the Venn diagram, we can observe that there are two events A and event B

n(A ∪ B) = 17 + 2

n(A ∪ B) = 19

And, The sample space would be,

n(S) = 17 + 2 + 15

n(S) = 34

Hence, Using the definition of probability,

P(A) = n(A) / n(S)

P (A) = 17/34

P (A) = 1/2

P(B) = n(B)/n(S)

P(B) = 2/34

P(B) = 1/17

So, We get;

P (A or B) = P (A) + P (B)

P (A or B) = 1/2 + 1/17

P (A or B) = 19/34

Height = 10 cm

The approximate total amount of felt used in the logo is calculated as

Amount = Area of semi-circle + Area of triangle
