what is the reduced form of 10/35
​

The correct option is (C) 95%.

The level of confidence associated with the interval $58.73 ≤ μ ≤ $68.40 is 95%.Explanation:The given interval represents the confidence interval of the population mean for the money that a typical college student spends per day during spring break.A confidence interval is defined as a range of values that is estimated to contain the true unknown value of a population parameter with a certain level of confidence.

Suppose the confidence level is C% and the margin of error is E, then the confidence interval can be calculated as: sample mean ± (critical value) × (standard error of the mean)Where the standard error of the mean is calculated as:standard error of the mean = standard deviation / sqrt(sample size)The sample size is 35, the sample mean is $63.57, the standard deviation is $17.32, the margin of error is ($68.40 - $63.57) / 2 = $2.915 and the critical value at 95% level of confidence with 34 degrees of freedom is 2.03.

Therefore, the confidence interval for the population mean is:$63.57 ± 2.03 × ($17.32 / sqrt(35))= $63.57 ± $5.99≈ [$57.58, $69.56]The interval [$58.73, $68.40] is contained within the confidence interval, which means that the level of confidence associated with it is at least 95%.Thus, the correct option is (C) 95%.

Therefore, the degree of the resulting polynomial is m + n when two polynomials of degree m and n are multiplied together.

What is polynomial?

A polynomial is a mathematical expression consisting of variables and coefficients, which involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents. Polynomials can have one or more variables and can be of different degrees, which is the highest power of the variable in the polynomial.

Here,

When two polynomials are multiplied, the degree of the resulting polynomial is the sum of the degrees of the original polynomials. In other words, if the degree of the first polynomial is m and the degree of the second polynomial is n, then the degree of their product is m + n.

This can be understood by looking at the product of two terms in each polynomial. Each term in the first polynomial will multiply each term in the second polynomial, so the degree of the resulting term will be the sum of the degrees of the two terms. Since each term in each polynomial has a degree equal to the degree of the polynomial itself, the degree of the resulting term will be the sum of the degrees of the two polynomials, which is m + n.

EXPLANATION:

Given;

We are given a graph of a function.

Required;

We are required to determine from the graph if the function is even, odd or neither even nor odd.

Solution:

To determine this from a graph, we should note that a function which is symmetrical with the y-axis is an even function. The graph which is symmetrical with the origin after a 180 degree rotation is an odd function.

Observe that if this graph is flipped from left to right (across the y-axis), it would not retain its original shape.

However, if the graph is rotated 180 degrees about the origin, it would retain its original shape.

Therefore, the graph depicted is an odd function

The integers are -3 and -1.

There are 9 dogs and 6 pigeons.

Each burger costs php 17 and each soda costs php 19.

Let's assume the two integers are x and y. We have the following equations: x + y = -4 and x - y = 2. Solving these equations, we find that x = -3 and y = -1.

Let's assume the number of dogs is d and the number of pigeons is p. We have the following equations: d + p = 15 (total number of pets) and 4d + 2p = 48 (total number of legs). Solving these equations, we find that there are 9 dogs and 6 pigeons.

Let's assume the cost of each burger is b and the cost of each soda is s. We have the following equations: 5b + 1s = 97 (Kelly's purchase) and 3b + 2s = 89 (Ken's purchase). Solving these equations, we find that each burger costs php 17 and each soda costs php 19.

To develop the estimated regression equation to predict the repair time given the number of months since the last maintenance service, the type of repair, and the repairperson who performed the service, we need to perform a multiple linear regression analysis.

The estimated regression equation can be represented as: Repair time = β0 + β1(Months since last maintenance) + β2(Type of repair) + β3(Repairperson)

where β0 is the intercept, β1 is the coefficient of months since last maintenance, β2 is the coefficient of type of repair, and β3 is the coefficient of repairperson.

To incorporate the assumption that if the type of repair is electrical and if Dave Newton performed the service, the repair time is lower, we can introduce an interaction term between the type of repair and the repairperson. The equation will then be:

Repair time = β0 + β1(Months since last maintenance) + β2(Type of repair) + β3(Repairperson) + β4(Type of repair × Repairperson)

The coefficients can be estimated using regression analysis techniques, and the resulting equation can be used to predict the repair time for a given set of values for the independent variables.

The probability that the sample proportion is greater than than 0.36 is 0.9952

When comparing a hypothesised proportion to a predetermined theoretical proportion of the population, a one proportion Z-test is employed as a hypothesis testing approach.

The test is used to establish the significance of the discrepancy between the sample proportion (hypothesised) and population theoretical proportion.

The formula to determine Z-statistics for sample proportion is

Z = p - P / √pq/n

where , p is sample proportion

P is population proportion

n is sample size

According to the question,

It is given that

Percentage that manager believes that of the company's orders come from first-time customers = 26%

P = 0.26

Sample size : n = 155

Sample Proportion : p = 0.36

q = 1 - 0.36

=> q = 0.64

We have to find the probability that the sample proportion is greater than than 0.36

z-statistic = 0.36 - 0.26 / √ (0.36×0.64)/155

=> 0.10/0.0385

=> 2.59

P( z > 2.59 ) = 1 - P( z < 2.59)

TCT is equal to the product topology on X x Y. To define the product topology on X x Y, we consider the collection of subsets of X x Y that can be written as the union of sets of the form U x V, where U is an open set in X and V is an open set in Y. This collection forms a basis for the product topology on X x Y.

Denote the product topology on X x Y by T. To show that the projection map Tx: (X x Y, T) → (X, T₁) given by (x, y) → x is continuous, we need to show that the preimage of every open set in X under Tx is open in X x Y.

Let U be an open set in X. Then the preimage of U under Tx is given by Tx^(-1)(U) = {(x, y) in X x Y | Tx(x, y) in

U} = {(x, y) in X x Y | x in U}

= U x Y, which is an open set in X x Y in the product topology T.

Hence, the map Tx is continuous.

Now, let T be another topology on X x Y, such that Tx: (X x Y, T) → (X, T₁) and Ty: (X x Y, T) → (Y, T₂) are continuous. We want to show that TCT, i.e., the topology generated by the collection of sets of the form U x V, where U is open in X under T₁ and V is open in Y under T₂, is equal to T.

To prove this, we need to show that every set open in T is also open in TCT, and vice versa.

First, let A be an open set in T. Then A can be written as a union of sets of the form U x V, where U is open in X under T₁ and V is open in Y under T₂. Since U is open in X under T₁, its preimage under Tx is open in X x Y under T. Similarly, the preimage of V under Ty is open in X x Y under T. Thus, A = (U x V) ∩ (X x Y) is open in X x Y under T.

Therefore, every set open in T is open in TCT.

Conversely, let B be an open set in TCT. Then B can be expressed as a union of sets of the form U x V, where U is open in X under T₁ and V is open in Y under T₂. Since U is open in X under T₁, its preimage under Tx is open in X x Y under T. Similarly, the preimage of V under Ty is open in X x Y under T. Hence, B = (U x V) ∩ (X x Y) is open in X x Y under T.

Therefore, every set open in TCT is open in T. Since the open sets in T and TCT are the same, we can conclude that T = TCT. Hence, we have shown that TCT is equal to the product topology on X x Y.

a. A is countably infinite.

Countably Infinite Sets: A set is countably infinite if its elements can be put in a one-to-one correspondence with the natural numbers (1, 2, 3, ...).

Examples of countably infinite sets include the set of all integers, the set of all positive even numbers, and the set of all fractions.

Uncountable Sets: An uncountable set is one that has a larger cardinality than the natural numbers.

It cannot be put in a one-to-one correspondence with the natural numbers.

The most well-known uncountable set is the set of real numbers (denoted by ℝ), which includes both rational and irrational numbers.

In statistics, p hat is used as an estimator of the population proportion (p) of a categorical variable. It is the sample proportion of the variable, which is calculated as the number of occurrences of a particular category in the sample divided by the total sample size.

The reason why p hat is used is that it provides an estimate of the unknown population proportion based on a representative sample. By using p hat, we can draw inferences about the population proportion with a certain level of confidence. This is important in hypothesis testing and confidence interval estimation, where we want to make statements about the population based on the information gathered from a sample.

Using p hat as an estimator of p is also beneficial because it has desirable statistical properties, such as being an unbiased estimator, having a sampling distribution that approaches normality, and having a known standard error.

If the new customer experience plan has more than a 5% point effect on client retention, with 90% confidence, at least 378 customers need to be included in the test.

customer retention rate = 60% per year

confidence = 90

To calculate the minimum number of customers that need to be included in the test, the formula for the sample size is:

n = (zα/2 + zβ)² (p1(1-p1) + p2(1-p2)) / (p1-p2)²

The z-score fat 90% of confidence =  1.645

The z-score for the desired power (1-β) = 1.282 for a power of 80%

p1 = 60%

p2 = 0.6 + 0.05 = 0.65

n = (1.645 + 1.282)² [(0.6)(1-0.6) + (0.65)(1-0.65)] / (0.65-0.6)²

n = 377.38

Read this for more help!

Step-by-step explanation:

That is okay if you do not understand the formula. We all have troubles with math in one spot or in another. With the a²+b²=c², we would have to go really slowly. Just for you!

Let´s do an example. Say we have a triangle, and for this we need to know our square roots! Say we have this triangle, and it has both a 3 and a 4 on its sides. Now a triangle had 3 sides. 2 sides are smaller, and then it would have a larger side, which is called the hypotenuse! That is the side we would need to figure out, because the hypotenuse is the largest side of the triangle, and we only have the smaller sides(3 and 4).

So we need to work with the formula.

So let us plug the example into the formula.

There is no specific order to how we would be putting the sides in. 3 could be b or it could be a. Same goes for the 4. It really does not matter because you would be getting the same answer no matter what.

a²+b²=c²

3²+4²=c²  

3²=9

4²=16

We need to add the two of those numbers, both 9 and 16 and we get 25. That is c². But we need c, because the hypotenuse is only c. So we need to take the square root of 25. And we get 5!

I will show you the equation again with 3 and 4 reversed.

4²+3²=c²

4²=16

3²=9

Like what we did above, we would get 25. And then take the square root! Same answer, so it really doesn't matter!

length of the arc of the circle formed by this central angle is 12.56 units.

The formula for calculating arc length is used to determine the length of the arc's curved line (a segment of a circle). The arc length is, to put it simply, the distance that passes across the curved line of the circle that forms the arc. Arc stability, weld current, and part concentricity are all factors that affect arc length. Arc stability, weld current, and part concentricity are all factors that affect arc length. The commercial welder's job in this situation is to maintain the electrode at a specific distance from the surface so that there is adequate room to prevent stubbing out.

Since, the length of an arc on a circle is:

l = r × θ

Where, r is the radius of the circle and  is the central angle ( in radian ) made by the arc,

Here,

r = 8 unit,

θ = 90° = 90 × (π/180) = π/2

( π radian = 180°)

Hence, the length of the given arc is,

l = 8 × (π/2)

l = 4π
