a random selection of indoors and outdoors pool managers are surveyed about the number of people in each age group that swim there. results from the survey are displayed in the two way table. based on the data, does there appear to be an association between pool type and age group? explain your reasoning​

Answer:   \(11\text{x}^{3}\text{y}^{4}\)

=====================================

Work Shown:

\(\left(121\text{x}^6\text{y}^8\right)^{1/2}\\\\\left(121\right)^{1/2}*\left(\text{x}^6\right)^{1/2}*\left(\text{y}^8\right)^{1/2}\\\\\sqrt{121}\text{x}^{6*(1/2)}\text{y}^{8*(1/2)}\\\\11\text{x}^{3}\text{y}^{4}\\\\\)

Therefore,

\(\left(121\text{x}^6\text{y}^8\right)^{1/2}=11\text{x}^{3}\text{y}^{4}\\\\\)

--------------

Explanation:

The exponent of 1/2 represents a square root. This is how \((121)^{1/2}\) turned into \(\sqrt{121}\) which then simplified to 11.

As for the variable terms, we multiply that outer exponent 1/2 with each exponent inside the parenthesis. Think of it like the distribution rule. It's not really distribution, but similar.

Recall that \((a^b)^c = a^{bc}\)

You can use the distributive property to multiply:

( y )( y² - 2y + 4 ) + ( 2 )( y² - 2y + 4) =

y³ - 2y² + 4y + 2y² - 4y + 8 =

y³ + 8

The -2y² and the 2y² cancel each other, and the 4y and -4y cancel each other out!

Answer:

The statement B. "The diagonals are perpendicular and one pair of adjacent sides are congruent." is not sufficient to prove that a parallelogram is a square.

A parallelogram is a quadrilateral with opposite sides that are parallel and equal in length. It has opposite angles equal in measure. The diagonals of a parallelogram bisect each other.

A square is a type of rectangle and a type of parallelogram. It is a four-sided polygon with all sides of equal length and all angles right angles. The opposite sides of a square are parallel and congruent, and opposite angles are congruent as well. The diagonals of a square are congruent and bisect each other. Additionally, the diagonals of a square are also perpendicular to each other.

Note that a rhombus also has congruent adjacent sides and perpendicular diagonals, but it's not a square.

Therefore, if the diagonals are perpendicular and one pair of adjacent sides are congruent, the parallelogram is not necessarily a square.

The conditional "If there is no rain, then there is no rainbow" is equivalent to "Rain is a necessary condition for a rainbow."

The statement "Rain is a necessary condition for a rainbow" implies that if there is no rain, then there will be no rainbow. This is captured by the conditional "If there is no rain, then there is no rainbow." If the necessary condition of rain is not met, it follows that a rainbow cannot occur.

On the other hand, the remaining conditionals are not equivalent to the statement "Rain is a necessary condition for a rainbow."

The conditional "If there is no rainbow, then there is no rain" is the inverse of the original statement. It suggests that if there is no rainbow, it implies there is no rain. While it is true that rain is often associated with rainbows, the absence of a rainbow does not necessarily mean there is no rain. Therefore, the inverse is not equivalent.

The conditional "If there is a rainbow, then there is rain" is the converse of the original statement. It states that if there is a rainbow, it implies there is rain. While this is often the case, it does not capture the necessary condition aspect of the original statement. There can be other factors that contribute to the formation of a rainbow, such as water droplets in the atmosphere, without the presence of rain. Therefore, the converse is not equivalent.

The conditional "If there is rain, then there is a rainbow" is the contrapositive of the original statement. It suggests that if there is rain, it implies there is a rainbow. While rain is indeed a common condition for the formation of rainbows, it does not capture the necessary condition aspect of the original statement. There can be rain without the occurrence of a rainbow, such as in light drizzles or heavy downpours without sunlight. Therefore, the contrapositive is not equivalent.

In summary, the only conditional that is equivalent to "Rain is a necessary condition for a rainbow" is "If there is no rain, then there is no rainbow."

#Select which one(s) of the following conditionals are equivalent to Rain is a necessary condition for a rainbow. If there is no rainbow, then there is no rain If there is no rain, then there is no rainbow. If there is a rainbow, then there is rain If there is rain, then there is a rainbow.

Answer:

decrease/decrease.

Step-by-step explanation:

both will decrease in quantity due to lack of food from the primary producer. Once the prey reduces, it affects the population of the predator.

The type of sampling used in this scenario is B. Stratified sampling. Stratified sampling involves dividing the population into distinct subgroups or strata and then selecting samples from each subgroup.

In this case, Miranda divides her day into three parts: morning, afternoon, and evening. Each part of the day represents a stratum or subgroup.  Miranda measures her breathing rate at 4 randomly selected times during each part of the day. This means she is taking samples from each of the three strata (morning, afternoon, and evening) and collecting data from within those subgroups.

By using stratified sampling, Miranda ensures that her samples represent the different parts of her day in a proportional and systematic manner, allowing her to capture potential variations in her breathing rate throughout the day.

We have to find the value of  `(sinθ+cosθ−tanθ)/(secθ+cscθ−cotθ)`

Let's find all trigonometric ratios:

We can say that:

\($$\tan \theta= \frac{opp}{adj}= \frac{-4}{3}$$$$\text\)

{Using the Pythagorean Theorem we can find the hypotenuse }

\($$$$\text{Hypotenuse = } \sqrt{(-4)^2+(3)^2}\)

\(= \sqrt{16+9}\)

= \(\sqrt{25}\)

=\(5$$$$\)

Substituting the values of sinθ, cosθ and tanθ in `

\(= \frac{\frac{3}{5} + \frac{-4}{5} - \frac{-4}{3}}{\frac{-4}{5} + \frac{5}{3} - \frac{-3}{4}}$$$$\)

\(=\frac{\frac{9}{15} + \frac{-12}{15} + \frac{20}{15}}{\frac{-16}{20} + \frac{25}{12} + \frac{3}{4}}$$$$\)

\(=\frac{\frac{17}{15}}{\frac{-14}{15}}$$$$\)

\(=-\frac{17}{14}$$\)

Therefore, \(`(sinθ+cosθ−tanθ)/(secθ+cscθ−cotθ)\)` is equal to

`-17/14` when `tanθ=−43` (Quadrant II).

We want to analyze the given linear equation, we will find that the slope is 60, and it means that he charges 60 per hour.

A general linear equation is written as:

y = a*x +b

In this case, we have the equation:

c(t) = 60*t + 65

Is easy to identify that the slope is equal to 60.

θ lies in the second quadrant (QII).

Given that csc(θ) > 0 and tan(θ) < 0, we can determine the quadrant in which θ lies based on the signs of the trigonometric function. Recall the signs of trigonometric functions in each quadrant: In the first quadrant (QI), all trigonometric functions are positive. In the second quadrant (QII), only sin(θ) and csc(θ) are positive. In the third quadrant (QIII), only tan(θ) and cot(θ) are positive. In the fourth quadrant (QIV), only cos(θ) and sec(θ) are positive. Given that csc(θ) > 0, we can conclude that θ lies in either QI or QII since csc(θ) is positive in both quadrants. Now, considering that tan(θ) < 0, which means the tangent function is negative, we can narrow down the possibilities. In QI, both tan(θ) and csc(θ) are positive, so it does not satisfy the given condition tan(θ) < 0. Therefore, θ must lie in QII. In conclusion, θ lies in the second quadrant (QII).

Step-by-step explanation:

For question 10, the present equivalent of $5,000 received in 2.5 years at 8% interest compounded monthly is approximately $4,096.37. For question 9, the engineer will repay $4,050.00.

For question 10, to calculate the present equivalent of $5,000 that will be received in 2.5 years at 8% interest compounded monthly, we can use the formula for the present value of a future sum compounded monthly:

Present Value = Future Value / (1 + (interest rate / number of compounding periods))^(number of compounding periods * number of years)

Calculating the present value:Present Value = $5,000 / (1 + (0.08 / 12))^(12 * 2.5) ≈ $4,096.37

Therefore, the present equivalent of $5,000 that will be received in 2.5 years at 8% interest compounded monthly is approximately $4,096.37.

For question 9, to calculate the amount of money that will be repaid at the end of 5 years for a $3,000 loan at 7% simple interest per year, we can use the formula for simple interest:

Interest = Principal * Interest Rate * Time

Calculating the interest:Interest = $3,000 * 0.07 * 5 = $1,050

Total amount repaid = Principal + Interest = $3,000 + $1,050 = $4,050.00

Therefore, the engineer will repay $4,050.00 at the end of 5 years.
