a towing vessel 35 meters in length, with a tow 100 meters astern, must show a minimum of how many masthead lights?

The percentage is the change over the original thus percentage error will be 2%.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

As per the given,

Estimation = 100

Actual amount = 102

% error = (Actual amount - Estimation)/Estimation  x 100

% error = (120 - 100)/100 x 100 = 2%

Hence"The percentage is the change over the original thus percentage error will be 2%".

To argue why the liberal arts are so important in education and leisure, one must discuss its Greek origin and how it is received today.

The term "liberal arts" comes from the Latin word "liberalis," which means free. It was used in the Middle Ages to refer to topics that should be studied by free people. Liberal arts refers to courses of study that provide a general education rather than specialized training. It encompasses a wide range of topics, including literature, philosophy, history, language, art, and science.The liberal arts curriculum is based on the idea that a broad education is necessary for individuals to become productive members of society. In ancient Greece, education was focused on developing the mind, body, and spirit.  

The study of the liberal arts is necessary to create well-rounded individuals who can contribute to society in meaningful ways. While the importance of the liberal arts has been debated, it is clear that they are more important now than ever before. The study of the liberal arts is necessary to develop the skills that are required in a rapidly advancing technological world.

Common denominator: 91/35 and 15/35

106/35.

Mixed form:  3 1/35

Brainliest and a heart would be the best, thank you.

Answer:

106/35 or 3 and 1/35 (depending on if the answer should be a mixed number or improper fraction)

Step-by-step explanation:

2 3/5 + 3/7

to add, you first convert to improper fractions by multiplying the denominator by the whole number and adding that product to the numerator

5*2=10 and 10+3=13 so the first fraction is now 13/5

the problem is now 13/5+3/7

when adding fractions the denominator needs to be the same. To find the least common multiple (or LCM) or a number you take the number's prime factorization and multiply together the largest number of each prime together. However, since these numbers are prime this is unnecessary and we can just multiply them. When multiplying to change the denominator or numerator you must always multiply the opposite side by the same number.  This is because a number over the same number equals one and thus you are altering the form without altering the intrinsic numerical value associated with it. For example, you would multiply 13/5 * 7/7 and get 91/35

Next we would multiply 3/7 * 5/5 because 5 is the number that would make the denominator of this fraction also equal 35 and get 15/35

We now have the equation 91/35 + 15/35

When adding the denominator stays the same and you add the numerators which would produce 106/35

We can convert this to a mixed number by seeing how many times 35 can go into 106 completely.

35 goes into 106 3 times with a leftover of 1 so the mixed version would be 3 and 1/35

The sample size for estimate the proportion of families in a certain area that are living below the poverty level is equals to the 318.75.

The standard error is a statistic term that is the standard deviation of its sampling distribution or an estimate of that standard deviation. In case of sample mean, it is called the standard error of the mean. Formula of standard mean is

\( SE =\sqrt{ \frac{\hat p (1 - \hat p)}{n}} \)

where, n--> sample size

We have a simple random sample for estimate the proportion of families,

Sample proportion = 0.15

Standard error = 0.02

We have to determine the sample size for the standard error of the estimate is .02.

Here, SE = 0.02, \hat p = 0.15

Using the standard score formula,

\( 0.02 =\sqrt{ \frac{0.15 (1 - 0.15)}{n}} \)

Squaring both sides

\( 0.02² = \frac{0.15 ×0.85 }{n} \)

\( 0.0004 = \frac{0.1275 }{n} \)

=> n = 318.75

Hence, required value is 318.75.

The unknown angles in the parallel lines are as follows;

x = 28

y = 23

When parallel lines are cut by a transversal line, angle relationships are formed such as linear angles, vertically opposite angles, interior angles, corresponding angles, alternate interior angles, alternate exterior angles etc.

using vertical angles and same side interior angles,

5y - 4 + 3y = 180 (same side interior angles are supplementary)

8y - 4 = 180

8y = 180 + 4

8y = 184

divide both sides by 8

y = 184 / 8

y = 23

Hence,

3y  = 2x + 13(corresponding angles)

corresponding angles are congruent.

Hence,

3(23) = 2x + 13

2x + 3(x+10) = 220.

2x + 3x + 50 = 220

The required value of y is 117°

Given AB and CD are parallel lines;

and EF is the transversal

Thus 2x + 16 = 3x - 12 { because they are corresponding angles }

On solving the above mentioned linear equation

we get,

x = 25

Thus the required angles are  2x + 16 = 50 + 16 = 66 degrees

and 3x - 12 = 75 - 12 = 63 degrees

And to find the value of y

we can use linear pair property

Thus y + 63 = 180

y = 180 - 63

This is due to the Beta error being a false negative, which would suggest that the lead levels did not go above the permitted limit even though they did.

As a result, the park would continue to be open and the general public would be exposed to a potentially dangerous situation.

On the other side, a false positive (also known as an Alpha error) would cause the park to be closed without a need and would prevent the public from accessing a secure park.

Compound interest formula

where

• A: final amount, in dollars

• P: principal, in dollars

• r: interest rate, as a decimal

• n: number of times interest is compounded per year

• t: time, in years

Substituting with P = $20,000, r = 0.05 (=5/100), n = 4 (quarterly means that the interest is compounded 4 times per year), and t = 3/4 years, we get:

The cost to repair a bicycle equals 150X, where X has the following probability function: f(x)=20x(1−x)3 Thus standard deviation of the repair cost is approximately 0.267.

To calculate the standard deviation of the repair cost, we need to find the variance first. The variance of a random variable X can be calculated using the formula:

Var(X) = E(X^2) - [E(X)]^2

First, let's calculate E(X):

E(X) = ∫(x * f(x)) dx, integrated from 0 to 1

E(X) = ∫(x * 20x(1−x)^3) dx, integrated from 0 to 1

E(X) = ∫(20x^2(1−x)^3) dx, integrated from 0 to 1

E(X) = 20 * ∫(x^2(1−x)^3) dx, integrated from 0 to 1

Solving the integral, we find E(X) = 4/7.

Next, let's calculate E(X^2):

E(X^2) = ∫(x^2 * f(x)) dx, integrated from 0 to 1

E(X^2) = ∫(x^2 * 20x(1−x)^3) dx, integrated from 0 to 1

E(X^2) = ∫(20x^3(1−x)^3) dx, integrated from 0 to 1

E(X^2) = 20 * ∫(x^3(1−x)^3) dx, integrated from 0 to 1

Solving the integral, we find E(X^2) = 4/15.

Now, we can calculate the variance:

Var(X) = E(X^2) - [E(X)]^2

Var(X) = (4/15) - (4/7)^2

Var(X) = 4/15 - 16/49

Var(X) = 40/105 - 48/105

Var(X) = -8/105

The standard deviation (σ) is the square root of the variance:

σ = sqrt(-8/105)

Thus, the standard deviation of the repair cost is approximately 0.267.

Answer:

Anna's final payment will be $2,574.21, which is the remaining balance on the loan.

Step-by-step explanation:

To calculate the amount of interest Anna will save by paying off the loan early, we need to first calculate the total amount of interest she would have paid if she had made all the scheduled payments. To do this, we can multiply the loan amount by the interest rate and the number of months the loan was taken out for:

$4,000 * 8% * 24 months = $768

Since Anna paid off the loan early, she will not pay all of this interest. The amount of interest she will save is the difference between the total interest and the amount of interest she has already paid. To calculate the amount of interest Anna has already paid, we can multiply the number of payments she has made by the interest portion of her payment:

9 payments * ($180.91 - $180.91 * 0.08) = $935.82

The amount of interest Anna will save is the difference between the total interest and the amount of interest she has already paid:

$768 - $935.82 = -$167.82

Anna will save a negative amount of $167.82 in interest because she has already paid more in interest than she would have if she had made all the scheduled payments.

Consider the same figure as given above. It is observed that DP/PE = DQ/QF and also in the triangle DEF, the line PQ is parallel to the line EF.

So, ∠P = ∠E and ∠Q = ∠F.

Hence, we can write: DP/DE = DQ/DF= PQ/EF.

The above expression is written as

DP/DE = DQ/DF=BC/EF.

It means that PQ = BC.

Hence, the triangle ABC is congruent to the triangle DPQ.

(i.e) ∆ ABC ≅ ∆ DPQ.
