Two length of the same frequency and amplitude moving in opposite directions combine to form a standing wave, which appears to be stationary. Given that the pool in this instance is 24 m long and has six loops, the wavelength is 4 m.

Wavelength = Length of Pool / Number of Loops

24 m / 6 loops

= 4 m

Wavelength

= 4 m

Two waves of the same frequency and amplitude moving in opposite directions combine to form a standing wave, which appears to be stationary. A stationary wave pattern is produced when the two waves collide and interfere with one another. Six loops make up the 24 m-long pool in this instance. As a result, the standing wave's wavelength is equal to the pool's length divided by the number of loops, or 24 m / 6 = 4 m. This indicates that the standing wave's wavelength is 4 metres. Standing waves can be used to determine a wave's speed because they are equal to wavelength times frequency. Understanding how waves behave in various contexts, such as swimming pools, oceans, or other bodies of water, can be helped by this.

For the given triangle the measure of the angle y is 65°.

Hence the correct option is C.

The angles that are created outside of a triangle are its external angles.

In other terms, the angle created between one of a triangle's sides and its neighboring extended side is the triangle's exterior angle.

And the exterior angle of a triangle is the sum of the interior angles of opposite sides.

The given angles are:

Exterior angle =  130°

Interior angles are y° and y°

Therefore,

Exterior angle  = y° + y°

130° = y° + y°

2y° = 130

Dividing both sides by 2 we get,

y° = 65°

Hence,

The measure of the angle y is 65°.

The temperature on mountaintop was -10° and the temperature on the ground was 10°. The solution has been obtained by using the linear equation.

What is a linear equation?

One is the degree of the linear equation. It is obvious that there are no variables in linear equations with exponents greater than 1. The graph's equation results in a straight line.

We are given that the temperature on the mountaintop was 20° lower than temperature on the ground.

Let the temperature on the ground be 'x'.

So, temperature on the mountaintop = x - 20

Also, the temperature on a mountaintop and the temperature on the ground had opposite values.

So,

x = - (x - 20)

On solving this, we get

⇒x = -x + 20

⇒2x = 20

⇒x = 10°

So, x - 20 = 10 - 20 = -10°

Hence, the temperature on mountaintop was -10° and the temperature on the ground was 10°.

The convincing evidence provided by the confidence interval depends on whether the interval includes or excludes the value of 12 ounces. If it excludes 12 ounces, it provides convincing evidence of a difference. If it includes 12 ounces, it does not provide convincing evidence of a difference.

To determine whether the confidence interval provides convincing evidence that the true mean volume is different than 12 ounces, we need to examine the confidence interval and its relationship to the value of 12 ounces.

A confidence interval is constructed based on sample data and provides a range of values within which the true population parameter is estimated to lie. The width of the confidence interval is influenced by factors such as the sample size, variability of the data, and chosen level of confidence.

If the confidence interval for the mean volume does not include the value of 12 ounces, it suggests that the true mean volume is likely to be different from 12 ounces. In this case, the confidence interval provides convincing evidence that the true mean volume is different from 12 ounces.

However, if the confidence interval does include the value of 12 ounces, it does not provide convincing evidence that the true mean volume is different from 12 ounces. This suggests that the data is consistent with the possibility that the true mean volume could be 12 ounces.

The purpose of the ninth was to assert the principle that the enumerated rights are not exhaustive and final and that the listing of certain rights does not deny the existence of other rights.

The Ninth Amendment was part of the Bill of Rights added to the Constitution on December 15, 1791. It states that all rights not enshrined in the Constitution belong to the people, not to the US government. In other words, the rights of citizens are not limited to those stipulated in the Constitution. Simply put, the Ninth Amendment declares that the enumeration of certain rights in the Constitution should not be construed as withholding or disrespecting others from people. According to Judge Harry A. Blackman, Roe v. Wade (1973),

Step-by-step explanation:

The probability that at least 1 out of 5 randomly selected American children (ages 3 to 5) is read to every day by someone at home is approximately 0.996.

The concept of probability is used to analyze and predict outcomes in various fields, including mathematics, statistics, physics, economics, and everyday life. It is based on the understanding that in a well-defined and controlled situation, the relative frequency of an event occurring approaches a stable value as the number of trials or observations increases.

The probability of a child being read to every day by someone at home is 58%, which can be expressed as 0.58. Therefore, the probability of a child not being read to every day is 1 - 0.58 = 0.42.

To find the probability that at least 1 out of 5 children is read to every day, we can calculate the complement of the probability that none of the 5 children is read to every day.

P(at least 1 read) = 1 - P(none read)

P(none read) = (0.42)⁵

P(at least 1 read) = 1 - (0.42)⁵

P(at least 1 read) ≈ 0.994.

Answer:

Third answer is correct

Step-by-step explanation:

As we can easily tell from the graphs one of the functions f(x) = -1, f(x) = 4 (the lower line is at -1 and the other (upper) line is at 4 on the y axis). So only the last two answers can be correct.

The lower line starts at -3 and ends at 3, so near f(x) = -1, x is more than -3 and less than 3 (also we can write it as -3 < x < 3). Therefore the third answer is correct.

Step-by-step explanation:

Step-by-step explanation:

Hey, there!!

Let's simply work with it,

60° + 2x° + (2x+12)° = 180° { being a linear pair}.

or, 72° + 4x = 180°

4x = 180° - 70°

\(x = \frac{108}{4} \)

Therefore, the value of x is 27°.

Now,

2x° = (2×27)°= 54°

(2x+12)° = 2×27°+12°= 66°.

(x+2)= 27+ 2= 29°

Now, The left angle is 27°.

Therefore, The answer is option A.

The ordered pair of C'' after the sequence of transformation is (-14, -5)

Here we have know that  ABC can be plotted at A (-14, 14), B (-8, 11) & C (-14, 5).

Here we all know that the y-axis reflection rule is written as,

=> (x, y) → (-x, y)

And the value of x coordinate flips in sign from positive to negative, or vice versa. Then the value of y coordinate stays the same.

Then the point is look like C(-14,5) will then reflect based on the following rule,

=> (x, y) → (x, y)

The transformed coordinates are look like,

=> (-14,5) ((-14),5)

=> (-14,5)→ (14,5)

Therefore, here we have point C' located at (14,5) after applying the y-axis reflection rule on point C.

Now, the next operation to do is is the 180 degree rotation.

And this can be clockwise or counterclockwise.

Then the rotation rule is written as

=> (x, y) → (-x,y)

Now, for this time both coordinates flip in sign.

Here we have know that this rule only works if the center of rotation is the origin.

Now, let us apply that rotation rule to C' to find where C" is located.

Then the rule can be written as,  (x, y) → (-x,y)

=> (14,5)→ (-14, -5)

Its correct

50 quarts of sparking water and 25 quarts of grape juice are needed for 75 quarts of punch.

An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.

Given that a punch recipe calls for 1(¹/₂) quart of sparkling water and 3/4 of a quart of grape juice.

The ratio of sparkling water to grape juice is,

1(¹/₂) : (3/4 quarts) = (3/2) : (3/4) =  2 : 1

The amount sparkling water in the total volume is 2 : (2+1) = 2/3 of the total volume. For a volume of 100 quarts, the sparkling water content is

2/3 · 75quarts = 50 quarts

Then the grape juice content is,

1/3 · 75 quarts = 25 quarts

Therefore, 50 quarts of sparking water and 25 quarts of grape juice are needed for 75 quarts of punch.
