Answer:

cos L = 55/73

Step-by-step explanation:

The triangle KLM is a right angle triangle. The ∠M = 90°. The side KM = 48, LK = 73, and ML = 55. The ratio that represents the cosine of ∠L can be solved below.

The right angle triangle formed has an hypotenuse , opposite and an adjacent side. Using the SOHCAHTOA principle one can find the ratio that represent the cosine of ∠L.

opposite side = 48

adjacent = 55

hypotenuse = 73

cos L = adjacent/hypotenuse

cos L = 55/73

(a). The Tanakas paid a total of $523,906.40 for the townhome.

(b). The Tanakas paid $206,906.40 in interest on their mortgage over the 15-year period.

Simple interest is the type of interest that is calculated on the principal amount only.

It is a fixed percentage of the principal amount that is charged or earned over a certain period of time, without any compounding of interest.

(a) The total amount they ended up paying for the townhome is the sum of the down payment and the total amount of the mortgage payments.

Down payment = $41,000

Total amount of mortgage payments = monthly payment x number of payments = $2675.04 x 12 months/year x 15 years = $482,906.40

Total amount paid = down payment + total amount of mortgage payments = $41,000 + $482,906.40 = $523,906.40

(b) The amount of interest paid on the mortgage can be calculated by subtracting the principal (the amount borrowed) from the total amount paid.

Principal = Total cost of townhome - Down payment = $358,000 - $41,000 = $317,000

Total interest paid = Total amount paid - Principal = $523,906.40 - $317,000 = $206,906.40

The total number of workers if, In a​ company, 90​% of the workers are women, If 440 people work for the company who​ aren't women is 4400.

What is percentage?

As it is clear from the term per-cent means measuring anything per hundred. For example, you get marks per 100 marks, so you get the percentage.

Given:

In a​ company, 90​% of the workers are women,

If 440 people work for the company who​ aren't women,

Calculate the percentage of people who aren't women as shown below,

The percentage of people who aren't women = 100% - the percentage of women

The percentage of people who aren't women = 100% - 90%

The percentage of people who aren't women = 10%

Assume that there are a total of x workers then according to the statement,

10% of x = 440

10 / 100 × x = 440

x = 440 × 100 / 10

x = 4400

Answer:

10m ;

500 m²;

300 m²

Step-by-step explanation:

Aspect ratio = Length / width

Perimeter = 120

Perimeter, P = 2(l + b)

l = Length, b = width

Yolanda :

Aspect ratio = 2

l/b = 2

l = 2b

Hence,

120 = 2(2b + b)

120 = 2(3b)

120 = 6b

b = 120/6

b = 20

Zhang :

Aspect ratio = 5

l/b = 5

l = 5b

Hence,

120 = 2(5b + b)

120 = 2(6b)

120 = 12b

b = 120/12

b = 10

Area of Zhang :

Length * width

5b * b

5(10) * 10

50 * 10

= 500m²

Area of Yolanda :

Length * width

2b * b

2(20) * 20

40 * 20

= 800 m²

Difference :

800m² - 500m²

The required reverse Euclidean algorithm is the solution to the modular equation (5x) mod 91 is

x = 6(mod 91).

Given that (5*x) mod 91 =32.

To solve the modular equation (5*x) mod 91 =32 using reverse Euclidean algorithm is to find the modular inverse of 5 modulo 91.

Consider  (5*x) mod 91 =32.

5x = 32(mod 91)

Apply the Euclidean algorithm to find GCD of 5 and 91 is

91 = 18 * 5 + 1.

Rewrite it in congruence form,

1 = 91 - 18 *5

On simplifying the equation,

1 = 91 (mod 5)

The modular inverse of 5 modulo 91 is 18.

Multiply equation by 18 on both sides,

90x = 576 (mod91)

To obtain the smallest positive  solution,

91:576 = 6 (mod 91)

Divide both sides by the coefficient of x:

x = 6 * 90^(-1).

Apply the Euclidean algorithm,

91 = 1*90 + 1.

Simplify the equation,

1 + 1 mod (90)

The modular inverse of 90 modulo 91 is 1.

Substitute the modular inverse in the given question gives,

x = 6*1(mod 91)

x= 6 (mod91)

Therefore, the solution to the modular equation (5x) mod 91 is

x = 6(mod 91).

Answer: 250

Step-by-step explanation:

This problem is attempting to explain the distributive property to you.

The distributive property states that if you have the numbers a, b, and c:

\((a*c) + (b*c) = c * (a+b)\)

In your specific case, this would look like this:

\((23+37) * 4\frac{1}{6}\)

\(60 * \frac{(4*6)+1}{6}\)

\(60*\frac{25}{6}\)

To simplify, we factor a 6 out of the equation:

Option B : observed frequencies  are the frequencies obtained from the performance of an experiment for a goodness-of-fit test .    

The frequency, or outcomes, that are gathered during an experiment are known as observed frequencies. This is frequently the collection of data that is documented in mathematics. The distinction between an observed frequency and an expected frequency is described on the display poster. Counts derived from experimental data are known as observed frequencies. In other words, you really take measurements when the data is being collected. For instance, you might roll a die ten times and then tally the number of times each number appears. Following the experiment, the count is made. The observed frequencies are these numbers, and the sign for an observed frequency is O. There are k entries in the table. There are n total observed frequencies. Calculating predicted frequencies involves multiplying the probability.

Step-by-step explanation:

Answer:

False

Step-by-step explanation:

Check if they are equal by making the denominators the same, then comparing the numerator. The least common denominator of 10 and 15 is 30 (I might be wrong on that, but it won't change the answer), so make each one 30 by multiplying the top AND bottom by the number needed to get the denominator to 30. In this case, 10 needs to be multiplied by 3, so 9/10 = 27/30, and 15 by 2, so 12/15 = 24/20. Now it is easy to see that 27/30 and 24/30 are NOT the same, so your answer is "false".

The percentage of jars will be filled with between 251 ml and 254 mL is 85.26%

To calculate the percentage of a number, we need to use a different formula such as:

P% of Number = X

where X is the required percentage.

If we remove the % sign, then we need to express the above formulas as;

P/100 * Number = X

We are given that;

Labeled quantity= 250ml

Distributed variable = 252 mL

o= 0.9 mL.

First, we need to calculate the z-score for 251 mL and 254 mL using the formula:

z = (x - μ) / σ

where x is the value we want to standardize, μ is the mean of the distribution, and σ is the standard deviation.

For 251 mL:

z = (251 - 252) / 0.9 = -1.11

For 254 mL:

z = (254 - 252) / 0.9 = 2.22

Next, we can use a standard normal distribution table or calculator to find the area under the curve between these two z-scores. If using a table, we look up the area corresponding to a z-score of 2.22 (0.9861) and subtract the area corresponding to a z-score of -1.11 (0.1335) to get:

0.9861 - 0.1335 = 0.8526

Therefore, the answer percentage will be approximately 85.26% .
