Step-by-step explanation:

edge 2020

On solving the inequality, 9 weeks of exercise are necessary to lower the individual’s resting heart rate below 70 beats per minute.

An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.

\(-0.1x^{3} + 0.6x^{2} +85 < 70\\\)

where, x is the number of weeks of exercise is necessary to lower the individual's resting heart rate below 70 beats per minute.

This cubic inequality can be solved by hit and trial method.

when x = 7.

\(-0.1x^{3} + 0.6x^{2} +85 < 70\\\)

\(=-0.1*7^{3} + 0.6*7^{2} +85\) = 80.1

80.1 > 70

Thus, x = 7 is not suitable.

when x = 8.

\(-0.1x^{3} + 0.6x^{2} +85 < 70\\\)

\(=-0.1*8^{3} + 0.6*8^{2} +85\) = 72.2

72.2 > 70

Thus, x = 8 is not suitable.

when x = 9.

\(-0.1x^{3} + 0.6x^{2} +85 < 70\\\)

\(=-0.1*9^{3} + 0.6*9^{2} +85\) = 60.7

60.7 < 70

Thus, x = 9 is suitable.

The approximate 95% confidence interval for the proportion of coworkers who have received this year's flu vaccine is (0.339, 0.501). Based on this information, it is true that 95% of the coworkers fall within the interval (0.339, 0.501), and we can be 95% confident that the proportion of coworkers who have received the vaccine is between 33.9% and 50.1%. However, it is false to say that there is a 95% chance that a randomly selected coworker has received the vaccine or that there is a 42% chance for a randomly selected coworker to have received the vaccine.

The approximate 95% confidence interval for the proportion of coworkers who have received this year's flu vaccine is (0.339, 0.501). Based on this information, we can determine which of the following statements are true:

a) 95% of the coworkers fall in the interval (0.339, 0.501).

This statement is true. The 95% confidence interval represents the range of values within which we can be 95% confident that the true proportion of coworkers who have received the flu vaccine lies. Therefore, we can say that 95% of the coworkers fall within the interval (0.339, 0.501).

b) We are 95% confident that the proportion of coworkers who have received this year's flu vaccine is between 33.9% and 50.1%.

This statement is true. The 95% confidence interval (0.339, 0.501) provides us with a range of values within which we can be 95% confident that the true proportion of coworkers who have received the flu vaccine lies. Therefore, we can say that we are 95% confident that the proportion of coworkers who have received the vaccine is between 33.9% and 50.1%.

c) There is a 95% chance that a randomly selected coworker has received the vaccine.

This statement is false. The 95% confidence interval does not represent a probability or chance for an individual coworker. It provides a range of values within which we can be 95% confident that the true proportion of coworkers who have received the flu vaccine lies. It does not give information about the likelihood of an individual coworker receiving the vaccine.

d) There is a 42% chance that a randomly selected coworker has received the vaccine.

This statement is false. The 42% represents the proportion of coworkers in the survey who have received the flu vaccine, but it does not represent the chance or probability for a randomly selected coworker to have received the vaccine. The 42% is a point estimate, not a probability.

e) We are 95% confident that between 33.9% and 50.1% of the samples will have a proportion near 42%.

This statement is false. The confidence interval (0.339, 0.501) does not directly provide information about the proportion of samples that will have a proportion near 42%. The confidence interval represents the range of values within which we can be 95% confident that the true proportion of coworkers who have received the flu vaccine lies, but it does not specifically address the proportion of samples near 42%.

The pattern of the data indicates a linear relationship or strong positive correlation between the average house prices and average monthly payments.

The monthly payment for a house costing $450,000 is $3,600.

A formulate connecting the average monthly payment with the average house price in slope-intercept form is y = 0.008x.

In Mathematics, a proportional relationship can be represented by this equation:

y = kx

Where:

Next, we would determine the constant of proportionality (k) as follows:

Constant of proportionality (k) = y/x

Constant of proportionality (k) = 8/1000

Constant of proportionality (k) = 1/125 or 0.008.

Therefore, a formula that connects the two variables is given by;

y = kx

y = 0.008x

When average house price (x) = $450,000, the average monthly payment (y) is given by:

y = 0.008(450,000)

y = $3,600.

In conclusion, we can logically deduce that the pattern of the data shows a linear relationship or strong positive correlation between the average house prices (x) and average monthly payments (y) because as the average house prices (x) increases, the average monthly payments (y) also increases.

Recall that ,

\(\sf\qquad\longrightarrow \dfrac{\sqrt{x}}{\sqrt{y}}=\sqrt{\dfrac{x}{y}}\)

On using this , we have ;

\(\sf\qquad\longrightarrow \sqrt{\dfrac{\cancel{64}\cancel{x}y^5}{\cancel{8x}}}\)

Simplify the square root ,

\(\sf\qquad\longrightarrow \pink{ 2y^2\sqrt{2y}} \)

Hence the required answer is 2y²√{2y} .

The correct answer is d. U.S. government purchases increase by $30,000; U.S. net exports decrease by $30,000; U.S. GNP increases by $30,000; and U.S. GDP is unaffected.

U.S. government purchases increase by $30,000; U.S. net exports decrease by $30,000; U.S. GNP increases by $30,000; and U.S. GDP is unaffected.

This is because the U.S. Air Force is paying a foreign citizen for their services, which counts as a U.S. government purchase. This will increase U.S. government purchases by $30,000.

                              However, since the payment is being made to a foreign citizen, it is not considered a part of U.S. net exports, which will decrease by $30,000. At the same time, the payment will increase U.S. GNP by $30,000, since it represents income earned by a U.S. citizen abroad.

Finally, since the payment does not represent any new production or economic activity within the United States, it will not affect U.S. GDP.

By applying the definitions of rigid transformation ((x, y) → (0.5 · x, 0.5 · y)) and dilation, we conclude that the coordinates of Q'(x, y) are (0.1).

Herein we must apply a rigid transformation into a given point to determine an image. Rigid transformations are transformations applied on a geometric locus such that Euclidean distance is conserved. Dilations are a kind of rigid transformations such that:

(x, y) → (k · x, k · y), for k > 0

If we know that Q(x, y) = (0, 2) and k = 0.5, then the coordinates of Q' are:

Q'(x, y) = (0.5 · 0, 0.5 · 2)

Q'(x, y) = (0, 1)

Yes, it is possible for a research study to have statistically significant results but limited clinical value. This can happen when the results obtained from the study are statistically significant but are not significant enough to influence clinical practice.

Statistical significance refers to the likelihood that a research finding is not due to chance. The p-value is used to determine statistical significance. The p-value measures the likelihood of getting a result as extreme as or more extreme than the one observed by chance. If the p-value is less than 0.05, the result is usually considered statistically significant. Results that are statistically significant but do not have any practical impact on the clinical field are considered to have limited clinical value. A statistical significance value does not imply that the result is significant in a clinical context. The size of the effect is also critical when interpreting statistical significance. Large sample sizes might result in minor differences being statistically significant but practically insignificant.

Therefore, the annual annuity payment can be approximately $6,069,727.

To calculate the size of the annual annuity payment, we can use the present value formula for an ordinary annuity. The formula is given by:

PMT = PV / [(1 - (1 + r)⁻ⁿ) / r]

Where:

PMT = Annual annuity payment

PV = Present value of the annuity

r = Annual interest rate

n = Number of periods

Given:

PV = $230 million

r = 8% = 0.08

n = 40 years

Using the formula, we can calculate the annual annuity payment:

PMT = 230,000,000 / [(1 - (1 + 0.08)⁻⁴⁰) / 0.08]

A firm experiences increasing returns to scale if inputs are doubled and output more than doubles.

When the firm's output grows at a faster rate than the growth in inputs, increasing returns to scale result. In this case, the company experiences economies of scale, which makes it more effective as it grows its production.

The firm is able to boost productivity and efficiency as it expands its scale of operations if inputs are doubled and output more than doubles.

This can be ascribed to a number of things, including specialisation, labour division, the use of capital-intensive technology, discounts for bulk purchases, and spreading fixed costs over a higher output. Lower average costs per unit of output result in higher profitability and competitiveness for the company.

The firm gains a number of benefits from growing returns to scale. First off, it lets the company to benefit from cost savings brought about by economies of scale, allowing it to manufacture goods or services for less money per unit. This may enable more competitive pricing on the market or result in larger profit margins.

Second, raising returns to scale can result in better operational effectiveness and resource utilisation. As the company grows in size, it will be able to use resources more wisely and profit from production volume-related synergies.market prices that are competitive.

A linear equation is an algebraic equation with simply a constant and a first-order (linear) component of the form y=mx+b, where m is the slope and b is the y-intercept. The above is sometimes referred to as a "linear equation with two variables," where y and x are the variables.

Ax+By=C is the typical form for linear equations in two variables. 2x+3y=5, for example, is a simple linear equation. It is rather simple to get both intercepts when an equation is stated in this way (x and y).

Let's call the number of minutes passed "t".

The total number of sticks in the wood pile after t minutes is given by the equation:

Woodpile = 5 + 7t - 3t = 5 + 4t

We want to find the time t it takes for the wood pile to have 45 sticks:

Hence, option D is correct.

Step-by-step explanation:

Given the system of equations

Line A: y = x − 1

Line B: y = −3x + 11

Arrange equation variables for elimination

\(\begin{bmatrix}y-x=-1\\ y+3x=11\end{bmatrix}\)

subtracting the equations

\(y+3x=11\)

\(-\)

\(4x=12\)

solving 4x = 12 for x

\(4x = 12\)

divide both sides by 4

\(\frac{4x}{4}=\frac{12}{4}\)

Simplify

\(x = 3\)

For y = x − 1, substutute x = 3

y = x-1

y = 3 - 1

The probability of getting 3 is P(A) = 1/216. The probability that sum being 3 is 1 / 216.

When three dice are thrown simultaneously, the probability that the sum is 3 is 1/216. A dice can show a minimum of one and a maximum of six dots, for a total of six sides, giving it a total of 6 * 6 * 6 = 216 possible outcomes.

:When three dice are thrown simultaneously, the probability that the sum is 3 is 1/216. The probability can be calculated as follows:

Let A be the event that the sum is 3. The number of ways to get 3 is 1, i.e., (1, 1, 1). The total number of possible outcomes is 6³,

since each die can have 6 possible outcomes.

Therefore, the probability of getting 3 is P(A) = 1/216.
