Write an equation to match this graph.

All u have to do is use the Traingle Inequality theorem, which states that the sum of two sides lenghts of a triangle is always greater than the third side. if this is true for all three combinations of added side lengths then you will have a triangle

Hope this helps :>

Answer:

3, 5, 7

Step-by-step explanation:

given 3 sides, for a triangle to be formed, then the sum of any 2 sides must be greater than the third side.

4 , 4 , 8

4 + 4 = 8 , not greater than 8, so does not form a triangle

1 , 2 , 3

1 + 2 = 3 , not greater than 3, so does not form a triangle

3 , 9 , 14

3 + 9 = 12 < 14 , so does not form a triangle

3 , 5 , 7

3 + 5 = 8 > 7

3 + 7 = 10 > 5

5 + 7 = 12 > 3

condition is satisfied , so will form a triangle

Answer: This is known as Gay-Lussac's Law.

The relationship states that the pressure and volume of a gas are directly proportional at constant temperature. Therefore, if the pressure is increased by 25%, the volume must be decreased by 25% to maintain the constant product of pressure and volume.

a. The shape of the sampling distribution is normal by the Central Limit Theorem.

b. The mean is 0.23.

c. The standard error is 0.125, which means that the sample proportions differ by around 0.125 from the mean of 0.23.

d. The probability is 0.2877 = 28.77%.

By the Central Limit Theorem, each sample has at least 10 successes and at least 10 failures, and the shape of the distribution is normal.

For each sample, the mean and the standard error are specified as follows:

Hence, the distribution of differences, the mean, and the standard error are specified as follows:

Using the z-score formula, the probability that the difference is greater than 30 is 1 subtracted by the p-value of Z when X = 0.3, Therefore:

Z = (0.3 - 0.23)/0.125

Z = 0.56

Z = 0.56

Answer: 11

The variation in the values is due to random error. Hence, it can be reduced by taking more observations to estimate the measure of the mass of the ring.

One way to minimize experimental error in this situation is to take multiple measurements and use the average of those measurements as the final value. This helps to account for any small fluctuations or inaccuracies in the individual measurements.

Also, it is important to ensure that the balance is properly calibrated and that the ring is placed on the balance in the same way each time.

Other ways to minimize experimental error include using a more precise measuring instrument, such as a digital scale, and ensuring that the lab environment is controlled and stable (i.e. no drafts or vibrations that could affect the measurements).

a. The total interest paid on the 25-year mortgage is $110411.

b. The total interest paid on the 30-year mortgage is $135644.

What is the meaning of APR?

Annual percentage rate (APR) is the term used to describe the annual interest produced by a sum that is levied against borrowers or distributed to investors. APR is a percentage that expresses the actual yearly cost of borrowing money over the course of a loan or the income from an investment. This does not account for compounding and includes any fees or additional costs related to the transaction. Consumers can compare lenders, credit cards, or investment products using the APR as a benchmark figure.

Given that, the amount that is borrowed is $220,000.

If you borrow it for 25 years, you will pay $1,101.37 monthly.

The amount that you need to pay is (1,101.37×12×25) = 330411.

The total interest is =  (330411 - 220,000) = $110411.

If you borrow it for 30 years, you will pay $987.90 monthly.

The amount that you need to pay is (987.90×12×30) = 355644.

The total interest is =  (355644 - 220,000) = $135644

5x/5 = 140.50/5

x = 140.50/5

x = 28.10

To find this, we need to take the quotient between the number of eggs and the number of batches, so we will get:

The results of operations between functions:

Case A: (f + g) (x) = x / (x + 9) + x³

Case B: (f - g) (x) = x / (x + 9) - x³

Case C: (f · g) (x) = x⁴ / (x + 9)

Case D: (f / g) (x) = 1 / [x² · (x + 9)]

Function (f / g) (x) has the following domain: x ∈ R - {- 9, 0}.

According to function theory, we can obtain a function with more complexity by operations between two functions, the most common operations are listed below:

Now we proceed to determine the resulting function:

Case A:

(f + g) (x) = f(x) + g(x)

(f + g) (x) = x / (x + 9) + x³

Case B:

(f - g) (x) = f(x) - g(x)

(f - g) (x) = x / (x + 9) - x³

Case C:

(f · g) (x) = f (x) · g (x)

(f · g) (x) = [x / (x + 9)] · x³

(f · g) (x) = x⁴ / (x + 9)

Case D:

(f / g) (x) = f(x) / g(x)

(f / g) (x) = [x / (x + 9)] / x³

(f / g) (x) = 1 / [x² · (x + 9)]

The domain of (f / g) (x) is the set of all values of x-values such that the function exists. In this case, we must determine the values of the denominator of (f / g) (x) such that it is not equal to zero.

x² · (x + 9) = 0

The binomial variable with mean 17 transformers and standard deviation √2.55 transformers.

In math standard deviation is defined as a measure of how dispersed the data is in relation to the mean.

Here we have know that the good electrical transformers operate at approximate 85% of the total time and 20 electrical transformers are chosen at random.

Here let us assuming the variable is a binomial variable.

Then we have written it as in the following form,

=> Mean = number of samples * probability

And the value of standard deviation is calculated as

=> Standard Deviation = √mean (1 − probability)

Here we know that the value of mean is calculated as,

=> 85% * 20 = 0.85*20 = 17 transformers

Then the value of Standard deviation is calculated as,

=> √mean * (1 − 0.85)

Apply the values on the formula, then we get,

=> √17 * 0.15 =√2.55 transformers.

Totally correct about the mentioned before is 2.5%. This is because the z-score for this situation is (494 - 686) / 96 = -2. According to the Empirical Rule, approximately 95% of observations will fall within 2 standard deviations of the mean. In this case, the question is asking for the percent of students who scored less than 494, which is below 2 standard deviations, so the answer is 2.5%.

The Empirical Rule states that for a normal distribution, approximately 68% of the data will fall within one standard deviation of the mean, approximately 95% of the data will fall within two standard deviations of the mean, and approximately 99.7% of the data would get fall within 3 standard deviations of the mean. So if we know the mean and standard deviation of a normal distribution, we can use this rule to estimate the percentage of data that falls within a certain range.

In this specific question, the mean of Math Level 2 SAT subject test score was 686 with a standard deviation of 96. We were asked to find the percent of students who scored less than 494. To find this we first calculated the z-score which is (494 - 686) / 96 = -2.

Since the z-score is -2 it means that it's 2 standard deviation below the mean, and according to the Empirical rule 95% of observations will fall within 2 standard deviations of mean. This means that 2.5% of observations will fall above 2 standard deviations and 2.5% of observations will fall below 2 standard deviations. So the answer is 2.5%.

If the ratio of dolphins to penguins is 2:5, then for every 2 dolphins, there are 5 penguins. If there are 30 penguins, you can use this ratio to find out how many dolphins there are. To find out how many dolphins there are, you can set up a proportion:

(number of dolphins) / (number of penguins) = (2) / (5)

You know that the number of penguins is 30, so you can substitute that in and solve for the number of dolphins:

(number of dolphins) / 30 = 2 / 5

Multiply both sides by 30 to solve for the number of dolphins:

number of dolphins = (2/5) * 30 = 6

So, if there are 30 penguins, there would be 6 dolphins.
