The height of the building after using proportion is  110.5 ft.

What is proportion ?

The main conceptual underpinnings on which proportion is described are ratio and fractions. When two ratios are written as a fraction using the formula a/b, ratio a:b, and then a proportion, they are equal. A and b in this situation can be any two integers. For grasping the myriad concepts in science and mathematics, the ratio and proportion are crucial constructing elements. With the right amount of proportion, a variety of problems in daily life, such as those encountered in the kitchen or in business when processing transactions, can be resolved. It facilitates comparison by establishing a relationship between two or more quantities.

Here House height = 13ft

Shadow of the house height = 20 ft

Shadow of the building height = 170ft

Noe using proportion ,

=> \(\frac{House height}{shadow of the house} = \frac{building height}{shadow of the building}\)

=> \(\frac{13}{20} = \frac{x}{170}\)

=> x=\(\frac{13*170}{20}\) =110.5 ft.

Hence the height of the building is 110.5 ft tall.

Answer:

a) 8

Step-by-step explanation:

a // b and c is transversal

So, alternate exterior angles are congruent.

12x - 12 = 10x + 4

Add 12 to both side

12x = 10x + 4 + 12

12x = 10x + 16

Subtract 10x from both sides

12x - 10x = 16

2x = 16

Divide both sides by 2

x = 16/2

x = 8

Step-by-step explanation:

Exterior angle given:

Interior angle is supplementary with exterior angle:

The description of the cosine function is \(\mathrm{f(x) = -10 \cos( \frac{2\pi}{3}) x + 10}\).

A cosine function's general form is given by:

\(\mathrm{f(x) = A \times cos(Bx + C)) + D}\)

where:

A stand for amplitude, or the ratio of the maximum to the minimum value.

B = 2π / period

C stands for horizontal phase shift.

(Midpoint between the Maximum and Minimum Values) D = Vertical Shift

We can determine the parameters for the specified function given the information given:

Period = 3 (This means B = 2π / 3)

Maximum value = 20

This means the amplitude A is half of this, so A = 20 / 2 = 10

Minimum value = 0

This means the vertical shift D is half of the difference between the maximum and minimum.

So, D = (20 - 0) / 2

= 10

The amplitude is negative because the function is a mirror of its parent function over the x-axis, hence A = -10.

Putting it all together, the function is:

\(\mathrm{f(x) = -10 \cos( \frac{2\pi}{3}) x + 10}\)

Hence the final expression after the transformation is \(\mathrm{f(x) = -10 \cos( \frac{2\pi}{3}) x + 10}\).

m and b are usually the ones a lot of people use. m is slope and b is y-intercept.

Answer:

%15.5

Step-by-step explanation:

200+(200x)=231

*x is the interest rate

so let's break down this question by going backwards. we can subract 200 from both sides since we cann easily get rid of +200. so you would get:

200x= 31

Now divide both sides by 200 to eliminate anything else, just to keep x alone.

x= 0.155

and a percent it would be %15.5

and to check:

200+(200*0.155)= 231

By simplifying the expression we get \(4x^{\frac{3}{2} }y^{\frac{5}{2} }\)

A number can be obtained by multiplying the square root of that integer by itself. The word "square root" is represented by the symbol \(\sqrt[2]{}\) .The opposite of squaring an integer is finding its square root.

According to the given information

Given x > 0

          y > 0

we need to simply the following expression

\(\sqrt[4]{256x^{6}y^{10} }\)

By simplifying

we get

= \((4^{4}x^{6} Y^{10}) ^{\frac{1}{4} }\)

= \(4x^{\frac{6}{4} } y^{\frac{10}{4} }\)

=  \(4x^{\frac{3}{2} }y^{\frac{5}{2} }\)

The one-way ANOVA controls for the Type I Error and should be used instead. When comparing multiple means, conducting multiple independent two-sample t-tests is not recommended because the probability of committing a Type I error increases with each additional test, leading to an inflated overall Type I error rate.

ANOVA is a better method for comparing means when there are more than two groups as it compares all means simultaneously and controls for Type I error.

(a) Null hypothesis: The type of crime does not depend on the age of the person who committed the crime.

Alternate hypothesis: The type of crime depends on the age of the person who committed the crime.

(b) To determine if there is a relationship between the age of a criminal and the nature of the crime at the 5% level of significance, we can use the critical value method.

First, we need to calculate the expected values for each cell under the assumption of independence between age and type of crime. We can calculate the expected values using the row and column totals:

Expected value = (row total * column total) / sample size

Expected values for the table are as follows:

graphql

Copy code

       Age       | Type of Crime

                 |   Violent  | Non-violent |   Total

CSS

Copy code

under 25    |      10       |     10        |     20

mathematical

Copy code

Total          |      40       |     40        |     80

Next, we can calculate the chi-square statistic using the formula:

chi-square = ∑ ((observed value - expected value)^2) / expected value

Using the observed and expected values from the table, we can calculate the chi-square statistic:

chi-square = ((15-10)^2)/10 + ((30-20)^2)/20 + ((10-10)^2)/10 + ((5-10)^2)/10 + ((30-20)^2)/20 + ((10-10)^2)/10 = 1.5 + 2.5 + 0 + 2.5 + 2.5 + 0 = 9

To determine if there is a relationship between the age of a criminal and the nature of the crime, we need to compare the chi-square statistic to the critical value from the chi-square distribution table. The degrees of freedom for this test is (number of rows - 1) * (number of columns - 1) = (3-1) * (2-1) = 2.

Using a significance level of 5% and 2 degrees of freedom, the critical value is approximately 5.991.

Since the chi-square statistic (9) is greater than the critical value (5.991), we reject the null hypothesis. This suggests that there is a relationship between the age of a criminal and the nature of the crime.

(c) Assumptions associated with this procedure:

The data used for the analysis is a random sample from the population of crimes in the city.

The observations are independent of each other.

The expected values in each cell of the contingency table are not too small (typically, they should be at least 5).

The chi-square test assumes that the variables being analyzed are categorical and the data is frequency-based.

If there are 6 red blocks and 4 blue blocks and a child is arranging them in a row, then there will be total of 210 possible arrangements.

In this scenario, there are a total of 10 blocks (6 red and 4 blue).

To determine the number of different arrangements possible, you'll need to find the combinations of these 10 blocks.

Using the formula for combinations (n! / (r! (n-r)!)), where n is the total number of blocks and r is the number of one type (e.g. red):

Total possible arrangements = 10! / (6!4!) = 210

So, there are 210 different possible arrangements of the 6 red blocks and 4 blue blocks in a row.

As per the unitary method, Nikhil has 21 pencils and Cortez has 63 pencils.

Let's say Nikhil has x number of pencils. Then, according to the problem, Cortez has three times as many pencils as Nikhil. Therefore, Cortez has 3x number of pencils.

Together, they have a total of 84 pencils. So, we can write an equation based on the number of pencils owned by Nikhil and Cortez as follows:

x + 3x = 84

Simplifying the equation, we get:

4x = 84

Dividing both sides by 4, we get:

x = 21

So, Nikhil has 21 pencils. Using the fact that Cortez has three times as many pencils as Nikhil, we can find out how many pencils Cortez has:

Cortez has 3x = 3(21) = 63 pencils.

Complete Question:

Lance has three times as many pencils as Nick, and they have 84 pencils together. How many pencils does each of them have?

Answer: 2/8.

Step-by-step explanation:

When we have this type of problem, the usual way to solve them is trying with known types of sequences.

I will start with the arithmetic sequence, where the difference between any two consecutive terms is a constant. And if we call this difference as D, we will have the recursive relation:

Aₙ = Aₙ₋₁ + D

To check if this sequence is an arithmetic sequence, we can take the first two terms and see the difference:

(5/8 - 3/4) = (5/8 - 6/8) = -1/8.

Now let's do the same, but with the second and third terms:

(1/2 - 5/8) = (4/8 - 5/8) = -1/8

The difference is the same, -1/8.

Now we can use the recursive relationship above and the last given term of the sequence to find the next one:

A₅ = A₄ + (-1/8)

A₅ = 3/8 - 1/8 = 2/8

Then the next fraction in the sequence was 2/8.

Answer: f(x) = -1 + 0x

Step-by-step explanation:

The fourth ordered pair using the two

sequences is ( 7/3 ,106) .

The first sequence is constructed by first multiplying the terms by 2 and then adding one-third starting from zero. So, sequence starts from 0.

First term of first sequence, a₁ = 0

a₂ = (2x0) + 1/3 = 1/3

a₃ = (2x1/3) + 1/3 = 2/3 + 1/3 = 1

a₄ = (2x1) + 1/3 = 2 + 1/3 = 7/3

Hence, the sequence is 0, 1/3, 1, 7/3, ...

The second sequence is constructed by first adding one half in terms and then multiplying by 4. The sequence starts from 1 ,

a₁ = 1

a₂ = (1 +1/2) × 4 = (3/2)4 = 6

a₃ = (6+1/2) x 4 = 13/2 x 4 = 26

a₄ = (26 + 1/2)× 4 = 53/2 x 4 = 106

Hence, the sequence is 1, 6, 26, se106, ...

Therefore, the fourth terms of the two sequences are the following, 7/3 and 106.

So, required ordered pairs is ( 7/3, 106).

The consumption bundle that will not be the consumer's choice, given the assumptions of choosing the optimal bundle, is option B) 30 snacks and 12 meals. To determine the optimal consumption bundle, we need to consider the consumer's budget constraint and maximize their utility.

Given that the price of snacks is $4 and the price of meals is $10, and the consumer has $240 remaining on their meal card, we can calculate the maximum number of snacks and meals that can be purchased within the budget constraint.

For option A) 5 snacks and 20 meals, the total cost would be $4 × 5 + $10 × 20 = $200. Since the consumer has $240 remaining, this bundle is feasible.

For option B) 30 snacks and 12 meals, the total cost would be $4 × 30 + $10 × 12 = $240. This bundle is on budget constraint, but it may not be the optimal choice since the consumer could potentially consume more meals for the same cost.

For option C) 20 snacks and 16 meals, the total cost would be $4 × 20 + $10 × 16 = $240. This bundle is also on budget constraint.

Since options A, C, and D are all feasible within the budget constraint, the only bundle that will not be the consumer's choice is option B) 30 snacks and 12 meals. The consumer could achieve a higher level of utility by reallocating some snacks to meals while staying within the budget constraint. Therefore, the correct answer is option B.
