The perimeter of a triangle is 42 meters. Side (a) is two less than side (b) and side (c) is triple side (b). What are the lengths of the three sides?

Answer:

If the shipping is included with the 4 dollars then it would be that she can buy 5 bracelets, but if it was 4$ + 3$ then she can only buy 2

Step-by-step explanation:

Answer:

Perimeter = 4.5√3 + 4.5

Area = 3.375√3

Step-by-step explanation:

Well you can first see that triangle ABC is a 30°60°90° triangle.

Since angle A is 60 and it is bisected, you will have a small 30°60°90° triangle and a 120°30°30° triangle.

You can say that DA is congruent to BD by Base Angle Theorem.

DA = 3

By using the ratios of the sides of the 30°60°90° you get that CD is 1.5 and CA is 1.5√3

CD = 1.5

CA = 1.5√3

BC = 4.5

Area = (4.5 * 1.5√3) / 3 = 6.75√3 / 2

Area = 3.375√3

By using the 30°60°90° ratio again, you get that BA = 3√3

Perimeter = 1.5√3 + 3√3 + 4.5

Perimeter = 4.5√3 + 4.5

I'm not 100% sure that the answer is right so check it.

1) The wavelength of A is equal to 6.98 × \(10^{-8}\)meters

2) The wavelength of B is equal to 3.45 × \(10^{-11}\) meters

Since we know that the wavelength = speed of light / frequency

The speed of light is 3.00 × \(10^8\) meters per second.

For light sample A with a frequency of 4.30 × 10^15 Hz can be calculated as;

wavelength of A = (3.00 ×  \(10^8\)  m/s) / (4.30 × 10^15 Hz)

wavelength of A = 6.98 ×  \(10^{-8}\) meters

For light sample B with a frequency of 8.70 × \(10^18\) Hz can be calculated as;

wavelength of B = (3.00 ×  \(10^8\) m/s) / (8.70 ×\(10^18\) Hz)

wavelength of B = 3.45 ×  \(10^{-11}\)  meters

Answer:

Step-by-step explanation:

(a) To find the probability that it is raining when you arrive in Oneirabad on a random day, we need to use the law of total probability.

Let A be the event that it is raining, and B be the event that it is the Wet season.

P(A) = P(A|B)P(B) + P(A|B')P(B')

Given that the Wet season lasts for 1/3 of the year, we have P(B) = 1/3. The probability that it is raining during the Wet season is 3/4, so P(A|B) = 3/4.

The Dry season lasts for 2/3 of the year, so P(B') = 2/3. The probability that it is raining during the Dry season is 1/6, so P(A|B') = 1/6.

Now we can calculate the probability that it is raining when you arrive:

P(A) = (3/4)(1/3) + (1/6)(2/3)

= 1/4 + 1/9

= 9/36 + 4/36

= 13/36

Therefore, the probability that it is raining when you arrive in Oneirabad on a random day is 13/36.

(b) Given that it is raining when you arrive, we can use Bayes' theorem to calculate the probability that your visit is during the Wet season.

Let C be the event that your visit is during the Wet season.

P(C|A) = (P(A|C)P(C)) / P(A)

We already know that P(A) = 13/36. The probability that it is raining during the Wet season is 3/4, so P(A|C) = 3/4. The Wet season lasts for 1/3 of the year, so P(C) = 1/3.

Now we can calculate the probability that your visit is during the Wet season:

P(C|A) = (3/4)(1/3) / (13/36)

= 1/4 / (13/36)

= 9/52

Therefore, given that it is raining when you arrive, the probability that your visit is during the Wet season is 9/52.

(c) Given that it is raining when you arrive, the probability that it will be raining when you return to Oneirabad in a year's time depends on the season. If you arrived during the Wet season, the probability of rain will be different from if you arrived during the Dry season.

Let D be the event that it is raining when you return.

If you arrived during the Wet season, the probability of rain when you return is the same as the probability of rain during the Wet season, which is 3/4.

If you arrived during the Dry season, the probability of rain when you return is the same as the probability of rain during the Dry season, which is 1/6.

Since the season you arrived in is independent of the weather when you return, we need to consider the probabilities based on the season you arrived.

Let C' be the event that your visit is during the Dry season.

P(D) = P(D|C)P(C) + P(D|C')P(C')

Since P(C) = 1/3 and P(C') = 2/3, we can calculate:

P(D) = (3/4)(1/3) + (1/6)(2/3)

= 1/4 + 1/9

= 9/36 + 4/36

= 13/36

Therefore, the probability that it will be raining when you return to Oneirabad in a year's time, given that it is raining when you arrive, is 13/36.

The terms vertical and horizontal often refer to directions. Vertical lines run up and down, and horizontal lines run sideways. The letter 'v' pointing down tells you which direction is vertical.

Anything parallel to the horizon is called horizontal. Vertical is the opposite of horizontal, so anything that forms a 90-degree angle (right angle) with the horizontal or horizontal line is said to be vertical. Therefore, horizontal lines are lines from left to right. Place a horizontal one next to it, like a person is lying down, as opposed to a vertical one. When sleeping (unless it's a horse) the body is horizontal. Horizontal ones are parallel to the ground or pointing in the same direction as the horizon.

Answer:

0.2333 = 23.33% probability that both of them have the secret decoder ring

Step-by-step explanation:

The cereals are chosen without replacement, which means that the hypergeometric distribution is used to solve this question.

Hypergeometric distribution:

The probability of x successes is given by the following formula:

\(P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}\)

In which:

x is the number of successes.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

\(C_{n,x}\) is the number of different combinations of x objects from a set of n elements, given by the following formula.

\(C_{n,x} = \frac{n!}{x!(n-x)!}\)

In this question:

45 boxes, which means that \(N = 45\)

22 have the secret decoder ring, which means that \(k = 22\)

Two boxes, which means that \(n = 2\)

What is the probability that both of them have the secret decoder ring?

This is P(X = 2). So

\(P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}\)

\(P(X = 2) = h(2,45,2,22) = \frac{C_{22,2}*C_{23,0}}{C_{45,2}} = 0.2333\)

0.2333 = 23.33% probability that both of them have the secret decoder ring

The expression 5x + 5x² can be written as a linear combination of (x − 1 − x²), (−1 − x²), and (1 − x). The coefficients of the linear combination are 6, -4, and -5, respectively.

A(x - 1 - x²) + B(-1 - x²) + C(1 - x) = 5x + 5x²

Expanding and simplifying the left side, we have:

(A - B + C) + (-Ax² - Bx² - Cx²) + (A - C)x

Comparing the coefficients of the like terms on both sides, we get the following system of equations:

A - B + C = 5   (coefficient of x)

-A - B - C = 0   (coefficient of x²)

A - C = 0   (coefficient of the constant term)

Solving this system of equations, we find A = C and B = -5. Plugging these values back into the equations, we get:

A - B + A = 5   =>   2A - 5 = 5   =>   A = 5/2

-A - B - A = 0   =>   -3A - 5 = 0   =>   A = -5/3

A - A = 0   =>   0 = 0

Since we obtain contradictory results for A, there is no consistent solution to the system of equations. Therefore, we cannot express 5x + 5x² as a linear combination of x - 1 - x², -1 - x², and 1 - x. Hence, the answer is DNE (Does Not Exist) in all answer blanks.

Now, let's simplify the expression 7 - 7-5x + 5x²:

7 - 7-5x + 5x² simplifies to 7 + 5x² - 7 + 5x = 5x² + 5x.

The Babylonian approximation 3;41 is equal to 3.683, which is very close to the correct value of 3.637. we need to calculate the correct value for the ratio of the area of a regular heptagon to the square of a side.

First, we need to convert the Babylonian approximation 3;41 into a decimal. To do this, we divide 41 by 60, which is equal to 0.683. Then, we add this decimal to the whole number 3, resulting in 3.683.

Next, we need to calculate the correct value for the ratio of the area of a regular heptagon to the square of a side. To do this, we use the equation A = (7/4)s^2, where A is the area of the heptagon and s is the length of the side. We can rearrange this equation to become (A/s^2) = (7/4). This results in a value of 3.637 for the ratio.

Finally, we compare the two values. 3.683 is very close to 3.637, so the Babylonian approximation is accurate.

The value of test statistic for test of independence is 62.5

The Chi-square test of independence checks that two variables are related or not. We have to count for two nominal variables. We also believe that the two variables are unrelated. The test allows us to determine whether or not our idea is plausible.

The sections that follow go over what we need for the test, how to perform it, understanding the results, statistical details, and p-values.

Given,

the table shows the beverage preferences for random samples of teens and adults.

For calculating the test statistics,

First wee need to calculate the expected values of every observed values.

Expected values for teens,

\(E(50)=\frac{250*400}{1000}=100\\\\E(100=)\frac{250*400}{1000}=100\\\\E(200)=\frac{400*400}{1000}=160\\\\E(50)=\frac{100*400}{1000}=40\)

Expected values for adults,

\(E(200)=250-100=150\\\\E(150)=250-100=150\\\\E(200)=400-160=240\\\\E(50)=100-40=60\)

Now, the test statistic is given by:

\(X^2=\frac{\sum\limits^n_{i=1}(O_i-E_i)^2}{E_i}\)

Where, Ei=expected value and Oi = observed value

\(X^2=\frac{(50-100)^2}{100}+\frac{(100-100)^2}{100}+...\frac{(200-240)^2}{240}+\frac{(50-60)^2}{60}=62.5\)

The most likely peptide segment to be part of a stable alpha helix at physiological pH would be option 3: pro-leu-thr-pro-trp. So, correct option is 3.

The stability of an alpha helix is influenced by several factors, including the propensity of the amino acid residues to adopt helical conformations and the presence of stabilizing interactions such as hydrogen bonding.

Proline (Pro) is known to disrupt helical structures due to its rigid cyclic structure, which introduces a kink and prevents the proper formation of hydrogen bonds. Option 1, which contains three consecutive glycines (Gly), may also hinder helix stability due to the absence of side chains that can participate in stabilizing interactions.

On the other hand, option 3 contains proline (Pro), leucine (Leu), and threonine (Thr), which have a relatively high propensity to form helices. Additionally, the presence of tryptophan (Trp) at the C-terminal end can contribute to stabilizing hydrophobic interactions within the helix.

While options 4, 5, 6, and 7 contain charged or aromatic residues, they may not provide the same level of stability as the combination of Pro, Leu, Thr, and Trp in option 3.

So, correct option is 3.

Answer:

These two triangles are similar triangles. This means that their side lengths are proportional to each other.

Thus, making line segment EC equal to "x", and BC equal to "y" we can write:

8/y = 28/(10+y)

The next step is to get rid of the fractions, which can be done by cross multiplying.

So we have:

8(10+y) = 28(y)

After distribution and some simplification, you should get the value of y.

80+8y = 28y

80 = 20y

80/20 = 20y/20

4 = y

y = 4

Knowing that y = BC, and y = 4, it is clear that BC = 4.

Since BC = 4, one can use the Pythagorean Theorem to solve for segment EC.

Pythagorean Theorem: a^2 + b^2 = c^2, where a and b are the side lengths of a right triangle, and c is the hypotenuse (in other words the longest side)

In our case, a and  b are 8 and 4 (the order doesn't really matter here).

So we have: 8^2 + 4^2 = c^2

64 + 16 = c^2

80 = c^2

c = sqrt 80

c  = 4 sqrt 5

And we arrive at the answer- EC = 4 sqrt 5, making B the correct choice.
