Step-by-step explanation:

The 90% confidence interval for the proportion of returns at the Houston store is approximately 0.0555 to 0.1945.

To construct a confidence interval for the proportion of returns at the Houston store, we can use the formula for confidence intervals for proportions. The formula is:

\(CI = p' \pm Z * \sqrt{\frac{(p' * (1 - p'))}{n}}\)

Where:

p' is the sample proportion (number of returns / sample size)

Z is the critical value corresponding to the desired confidence level (90% confidence corresponds to Z = 1.645)

n is the sample size

In this case, the sample proportion (p') is 10/80 = 0.125, the critical value(Z) for a 90% confidence level is 1.645, and the sample size (n) is 80.

Substituting these values into the formula, we get:

\(CI = (0.125 \pm 1.645) * \sqrt{\frac{(0.125 * (1 - 0.125))}{80}}\)

Calculating the values inside the square root:

\(\sqrt{\frac{0.125 * (1 - 0.125))}{80}} \approx 0.0422\)

Substituting this value back into the formula:

\(CI = (0.125 \pm 1.645) * 0.0422\)

Calculating the values inside the confidence interval:

0.125 ± 0.0695

The lower bound of the confidence interval is:

0.125 - 0.0695 ≈ 0.0555

The upper bound of the confidence interval is:

0.125 + 0.0695 ≈ 0.1945

So, The range of the proportion of returns at the Houston store's 90% confidence level is about from 0.0555 to 0.1945.

Answer:

Perimeter: 4+\(\pi \\\) mm

Area: \(\pi\) mm^2

Step-by-step explanation:

Perimeter:

90/360 * 4\(\pi \\\) +2 + 2 = 4+ \(\pi \\\)

Area:

90/360 * 4\(\pi\) = \(\pi\)

Answer: 7.14 mm and 3.14 mm²

Step-by-step explanation:

The perimeter of a figure is the total length on the outside of the figure. A regular circle has a perimeter of \(2\pi r\), where r is the radius and \(\pi\) is an irrational constant, approximately 3.14.

Due to the right angle, we know that this is a quarter circle, as it is a quarter of 360°, or a full circle. Hence, the curved portion of the quarter circle is \(\frac{1}{4}* 2\pi r\) or \(\frac{1}{2} \pi r\). The radius is 2 mm, so this value is

\(\frac{1}{2} \pi*2=\pi\)

However, this isn't the total perimeter, as there are straight edges in the figure too. Both edges are radii of the whole circle, so both would be 2mm. Their total is

\(2+2=4\)

By adding \(\pi\) to 4 we get \(\pi +4\) or 7.14 mm.

The  area is the total space enclosed by a figure. The total area of a whole circle is \(\pi r^2\), where r is still the radius. Since this is a quarter circle, it would take up a quarter of the area, or \(\frac{1}{4} \pi r^2\). We can plug in 2 for r and solve to get the area.

\(\frac{1}{4}\pi*2^2\\\frac{1}{4}\pi*4\\\pi\)

Hence, the area is \(\pi\), or around 3.14 mm².

An enumerator is a special data type in some programming languages that allows us to give names to integer values, making the code more readable and easier to maintain.

However, an enumerator cannot be directly assigned to an int variable because they are not compatible data types. An int variable can only store integer values, while an enumerator is a named constant that represents an integer value.

To assign an enumerator to an int variable, we need to explicitly cast the enumerator to an int using type conversion.

The answer to this question based on limits is -4/3

What is limits?

Limits are very interesting concepts in mathematics which are veryuseful when we are dealing with numbers like infinity or numbers where some functions are not defined

Concepts of limits give us brief understanding that why these things are not defined

Solution;

We are asked to calculate a limit

By limits laws we can apply limit to both numerator and denominator respectively

Numerator = lim x--->2 2x-2

= just put 2 in place of x we will get 4 - 2 = 2 ans

Denominator = 2f(3x) - x

put limit as x = 2 in this we get

2 f(6) - 2

we need values of f(6) we can take from graph that f(6) = -3/2

hence answer to our question is 2 divided by -3/2

which in turn our answer for this limit problen is -4/3

The value of p is -4 in the linear equation in one variable 4 - 3p = -5p - 24 the answer is -14.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

The linear equation in one variable is:

4 - 3p = -5p - 24

After solving:

5p - 3p = -24 - 4

2p = -28

What is function ?

A function in mathematics from a set X to a set Y allocates exactly one element of Y to each element of X. The sets X and Y are collectively referred to as the function's domain and codomain, respectively.

a mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable).

A function is a type of rule that produces one output for a single input. Source of the image: Alex Federspiel. This is illustrated by the equation y=x2. Any input for x results in a single output for y. Considering that x is the input value, we would state that y is a function of x.

f o g is composite function, y values of g passed as x values into f.

f o g = 1/(x² + 5x)

A parallelogram is a straightforward quadrilateral with two sets of parallel sides in Euclidean geometry and in the given parallelogram the required value of x is 3 units.

A parallelogram is a straightforward quadrilateral with two sets of parallel sides in Euclidean geometry.

A parallelogram's facing or opposing sides are of equal length, and its opposing angles are of similar size.

In a parallelogram, the diagonals are split in half while the opposite sides are equal.

In a rhombus, all four sides are equal and the diagonals intersect at 90 degrees.

So, a parallelogram's diagonals cut each other in half.

Hence, WC = CY.

This is:

2x + 5 = 3x + 2

Take away 2x from each side:

5 = 3x - 2x + 2

5 = x + 2

Take away from both sides:

5 - 2 = x + 2 - 2

yes, actually it is possible. The mathematical expression f(x)=exp or ex denotes the exponential function.

The mathematical expression f(x)=exp or ex denotes the exponential function. The word, unless specifically stated differently, normally refers to the positive-valued function of a real variable, though it can be extended to the complex numbers or adapted to other mathematical objects like matrices or Lie algebras. When the input variable x appears as an exponent in the formula f(x) = axe, an exponential function is indicated. The exponential curve is influenced by both the exponential function and the value of x.

One of the key mathematical operations is the exponential function (though it would have to admit that the linear function ranks even higher in importance). We allow the exponent to be the independent variable to create an exponential function. The formula f(x)=2x is a straightforward example.

Hence, yes, actually it is possible.

Option D (9) is not a probability and is not a possible answer choice for a probability question.

To find the probability of the intersection of events A and B (denoted as P(A ∩ B)), we need to know how many elements are in both A and B. Since there are 2 repeated elements between the events, this means that there are a total of 7 - 2 = 5 distinct elements between them.

Therefore, P(A ∩ B) = 5/7.

Note that none of the answer choices provided match this result exactly. Option A is the closest with a probability of 4/7, but this is the probability of A alone, not the intersection of A and B.

Answer:

\((a)120^\circ\\(b)60^\circ\)

Step-by-step explanation:

In the diagram BC(Main Street) is parallel to AD(Willow Lane)

Therefore, ABCD is a Trapezoid.

Since in a trapezoid, adjacent angles are supplementary

Therefore:

\(\angle C+ \angle D=180^\circ\\\angle C+ 60^\circ=180^\circ\\\angle C=180^\circ- 60^\circ\\\angle C=120^\circ\)

Since \(AB \cong CD\), ABCD is an Isosceles Trapezoid.

In an Isosceles trapezoid, the base angles are congruent:  

Therefore:\(\angle A \cong \angle D$ and \angle B \cong \angle C\)

Therefore:

\(\angle A \cong \angle D=60^\circ\\\angle B \cong \angle C=120^\circ\)

(a)

The angle between Main Street and the west path is \(\angle CBA = 120^\circ\)

(b)

The mean and variance of a binomial random variable with n trials and success probability p are np and np(1-p), respectively.

The mean and variance of a binomial random variable with n trials and success probability p are given by the following formulas:

Mean = np

Variance = np(1-p)

Where n is the number of trials and p is the probability of success in each trial.

To understand this better, let's consider an example. Suppose we conduct an experiment where we toss a coin 10 times and we want to know the probability of getting exactly 5 heads.

This is a binomial experiment because there are only two possible outcomes (heads or tails) and each trial is independent of the others. The probability of getting a head on any given trial is 0.5.

Using the formula for the mean, we get:

Mean = np = 10 x 0.5 = 5

This means that on average, we can expect to get 5 heads out of 10 tosses.

Using the formula for the variance, we get:

Variance = np(1-p) = 10 x 0.5 x (1-0.5) = 2.5

This means that the spread of the distribution is relatively large, indicating that there is a significant amount of variability in the number of heads we can expect to get.

Let's call the first odd integer "x". Then, the next 4 consecutive odd integers would be x+2, x+4, x+6, and x+8.

To find the sum of the three smallest, we add x + (x+2) + (x+4) = 3x + 6.
To find the sum of the two largest, we add (x+6) + (x+8) = 2x + 14.
We know that the sum of the three smallest is 3 more than the sum of the 2 largest, so we can set up an equation:
3x + 6 = 2x + 14 + 3
Simplifying this equation, we get:
x = 11
So the first odd integer is 11, and the 5 consecutive odd integers are: 11, 13, 15, 17, and 19.
To check our work, we can verify that the sum of the three smallest is indeed 3 more than the sum of the 2 largest:
11 + 13 + 15 = 39
17 + 19 = 36
39 = 36 + 3
