a. The individuals in this study are Canadians of retirement age (65+). The variable in this study is whether or not they have diabetes.b. Suppose, only for the purpose of part (b) of this question, that the true proportion of Canadians of retirement age who have diabetes is actually 0.25.

i. If we were to take many SRSs of size 145, the approximate sampling distribution of the resulting sample proportions would be a normal distribution with a mean of 0.25 and a standard deviation of \(sqrt((0.25(1-0.25))/145)=0.04/12=0.0333.\)This is because the sample size is large (n > 30) and we assume the sampling distribution to be normal.

ii. Based on this sampling distribution, the probability of observing a sample proportion as small as what we observed (0.20) is calculated as follows:  Z = (0.20 - 0.25) / 0.0333 = -1.50P(Z < -1.50) = 0.0668 or 6.68%.

Therefore, the probability of observing a sample proportion as small as what we observed (0.20) is 6.68%.

c. Using the sample proportion of 0.20, the 95% confidence interval for the true proportion p is calculated as follows:

Margin of error = 1.96 x sqrt((0.20(1-0.20))/145) = 0.055

Interval = 0.20 ± 0.055 = (0.145, 0.255)

Therefore, we are 95% confident that the true proportion of Canadians of retirement age who have diabetes is between 0.145 and 0.255.

Solution:

Given:

From the graph, the x-intercept exists at (0,0) and (6,0).

The maximum value is (3,120).

The x-intercept represents the break-even points. The company was not in profit or loss when no pen was sold and when 6 pens were sold, the profit was $0 at these two points.

The maximum value of the graph represents the maximum profit made by the company. The company made a maximum profit of $120 when 3 pens were sold.

The interval where the function is increasing is from negative infinity to x = 3. This shows that the more pen sold, the higher the profit made.

The interval where the function is decreasing is from x = 3 to positive infinity. This shows that the less pen sold, the lower the profit made.

The approximate average rate of change of the graph from x = 3 to x = 5 is;

The rate represents a decrease of $30 for every pen sold across the decreasing interval.

The correct equations for the measures of the unknown angles x and y are:

x = cos(a), y = sin(a).

The trigonometric functions (sin, cos, tan) are mathematical functions that describe the relationships between the sides and angles of a right triangle. Given an angle a in a right triangle, we can use these functions to find the values of the side ratios for that angle. For example:

sin(a) = opposite side / hypotenuse

cos(a) = adjacent side / hypotenuse

tan(a) = opposite side / adjacent side

In these expressions, "opposite side" refers to the side opposite the angle a, "adjacent side" refers to the side adjacent to the angle a, and "hypotenuse" refers to the longest side in the right triangle (the one opposite the right angle).

The inverse trigonometric functions\((sin^-1, cos^-1, tan^-1)\) are the reverse of the trigonometric functions. Given a value of a trigonometric function, the inverse function returns the measure of the angle (in radians) for which that value is the result. For example:

\(sin^-1(y) = a (where y = sin(a))cos^-1(x) = a (where x = cos(a))tan^-1(t) = a (where t = tan(a))\)

So, the correct equations for the measures of the unknown angles x and y are:

\(x = cos^-1(x)y = sin^-1(y)\)

The SI base unit for measuring temperature is 4) Kelvin. Temperature is a physical quantity that measures the degree of hotness or coldness of an object or a system.

The International System of Units (SI) is a globally accepted system of measurement. In SI, temperature is measured using the Kelvin (K) scale, which is the SI base unit for temperature.

The Kelvin scale is based on the absolute zero point, which is the lowest possible temperature where all molecular motion ceases. Absolute zero is defined as 0 Kelvin (0 K). Temperature increments on the Kelvin scale are equivalent to increments on the Celsius scale, with 1 Kelvin being equal to 1 degree Celsius.

The other options listed, such as Celsius and Fahrenheit, are not SI base units for temperature but are commonly used in everyday contexts. Celsius (°C) is widely used in many countries and is based on the Celsius scale, which sets the freezing point of water at 0°C and the boiling point of water at 100°C at sea level. Fahrenheit (°F) is used mainly in the United States and a few other countries and has its freezing point at 32°F and boiling point at 212°F at sea level. However, neither Celsius nor Fahrenheit is considered an SI base unit for temperature.

There is only a 0.62% chance that the average length will be less than 2.4 inches. Therefore, we can conclude that it is unlikely for the average length of 100 randomly selected fish to be less than 2.4 inches.

Use the central limit theorem, which states that the distribution of sample means will be approximately normal regardless of the distribution of the population, as long as the sample size is large enough.

In this case, we are given that the length of one kind of fish is normally distributed, with a mean of 2.5 inches and a standard deviation of 0.4 inches. We want to find the probability that the average length of 100 randomly selected fish is less than 2.4 inches.

To apply the central limit theorem, we need to calculate the mean and standard deviation of the sampling distribution of the sample mean. The mean of the sampling distribution will be equal to the population mean, which is 2.5 inches. The standard deviation of the sampling distribution can be calculated using the formula:

standard deviation = population standard deviation / square root of sample size

In this case, the population standard deviation is 0.4 inches, and the sample size is 100, so:

standard deviation = 0.4 / sqrt(100) = 0.04 inches

Now that we have the mean and standard deviation of the sampling distribution, we can use the z-score formula to find the probability of obtaining a sample mean of less than 2.4 inches:

z = (sample mean - population mean) / standard deviation

z = (2.4 - 2.5) / 0.04 = -2.5

Using a standard normal distribution table, we can find that the probability of obtaining a z-score of -2.5 or less is approximately 0.0062. This means that the probability of obtaining a sample mean of less than 2.4 inches is approximately 0.0062.

In other words, if we were to randomly select 100 fish from this population and calculate the average length, there is only a 0.62% chance that the average length would be less than 2.4 inches. Therefore, we can conclude that it is unlikely for the average length of 100 randomly selected fish to be less than 2.4 inches.

                                                                                         y ≤ \(x^{2}\)  + 4

(h, k) = (1, -4), p = \(\frac{1}{4}\)

\(y > x^{2} -2x-3\)

rewrite y > \(x^{2} -2x-3\) in the standard form

\(4.\frac{1}{4} (y-(-4))=(x-1)^{2}\)

 y ≤ \(x^{2}\)  + 4

therefore parabola properties are:

(h,k) = (1, -4), p= \(\frac{1}{4}\)

The basic parabola has the accompanying properties: It is symmetric about the y-axis, which is an axis of symmetry. The base worth of y occurs at the beginning, which is a base-defining moment. It is also called the vertex of the parabola. The arms of the parabola go on indefinitely.

The missing sides of the right triangle are DE = 4.195 and DF = 6.527 and the missing angle is 50°.

In this question we find a right triangle with a known side and two known angles. The missing sides can be found by following trigonometric functions:

tan F = DE / EF

cos F = EF / DF

And the angle D is found by the following expression:

D = 90° - F

If we know that EF = 5 and F = 40°, then missing sides and angle are, respectively:

DE = EF · tan F

DE = 5 · tan 40°

DE = 4.195

DF = EF / cos F

DF = 5 / cos 40°

DF = 6.527

Answer:

  Practice -- lots of it

Step-by-step explanation:

I usually choose a solution method that I believe will find the desired answer for me in the least number of simple steps. What constitutes a "simple" step depends on a number of things:

__

I often choose a graphing calculator as my first approach to solving a quadratic. It easily shows the roots, and can show the vertex. (Sometimes, scaling the graph is required, so I actually prefer to use a touch-screen for the purpose. It is easier to "pinch" than to type in possible graph limits by trial and error.) The answer is generally provided to 3 or 4 significant figures, which is usually enough to tell if the solution is rational or irrational.

The easiest way to describe an integer (or rational) solution to someone else (on Brainly, for example) is usually to show the factoring of the quadratic. Finding the roots with a graphing calculator significantly aids the factoring process. (It is much easier to "find" the solution if you know the solution before you start looking.)

__

As we said at the beginning, the answer to your question is "practice." Many curricula try to offer opportunities to practice. I find most of these pretty annoying. What I suggest is that you find your own internal motivation to practice solving different kinds of quadratics in several different ways. That is, solve the same quadratic by ...

It might take you a couple of hours of work to learn the best way to solve an equation in under 5 minutes.

In this process, you will discover what you need to know to choose a method that works nicely for you. I believe you will find that total familiarity with arithmetic facts (sums, products, squares) and operations on all the different ways to represent numbers (integer, decimal, fraction, percent, scientific notation) will help you significantly.

Some "area" problems give you the difference of dimensions (length and width), and ask you to find the dimensions that give a specific area. This can be solved by (x)(x -d) = A. If you don't immediately recognize factors of A that differ by d, then you might have to resort to the quadratic formula to solve this.

Another approach is to let the variable represent the average dimension. Then the equation becomes (x -d/2)(x +d/2) = A, which is a "difference of squares" form that is much more easily solved. The solution for x is √(A +(d/2)²), and all you have to do is add and subtract d/2 from that solution to find the dimensions. This is an example of what I mean by transforming the problem.

let us call the number x for now

the number (x) is multiplied by 3 to give us

3x

then,

it is added to 6 to give

3x + 6

then, our sum is divided by 8:

(3x + 6) / 8

according to the question, the result is 6

therefore,

3x + 6 / 8 = 6

if we cross multiply,

3x + 6 = 8 ( 6 )

3x + 6 = 48

collecting like terms,

3x = 48 - 6

3x = 42

divide through by 3 to give

3x / 3 = 42 / 3

x = 14

therefore, x = 14

to reassure us of our answer,

since (3(x) + 6) / 8 = 6

and we know that x = 14,

therefore,

(3(14) + 6) / 8 = 6

(42 + 6) / 8 = 6

48 / 8 = 6

6 = 6

therefore, we are now sure that x = 14

The given procedure does not result in a binomial distribution because it does not satisfy the criteria of having only two possible outcomes and independent trials.

No, this procedure does not result in a binomial distribution. In order for a distribution to be binomial, it must meet four criteria: (1) there must be a fixed number of trials; (2) the trials must be independent; (3) there must be only two possible outcomes (i.e., success or failure); and (4) the probability of success must remain the same in all trials.

In the given procedure, there are more than two possible outcomes (i.e., the different TV shows that the college students can choose) and the trials are not independent. Therefore, the procedure does not satisfy two of the four criteria necessary for a binomial distribution.

A binomial distribution can be described by the formula:

\(P(x) = nCx * p^x * (1 - p)^(n - x)\)

where n is the number of trials, x is the number of successes, and p is the probability of success. Since the given procedure does not meet the criteria for a binomial distribution, this formula does not apply.
