The derivative of the function h(t) = 17 cot⁻¹(t) + 17 cot⁻¹(1/t) is h'(t) = -17/(1+t²) + 17/(t² + 1).

The derivative of the function h(t) = 17 cot⁻¹(t) + 17 cot⁻¹(1/t) can be found using the chain rule and the derivative of the inverse cotangent function.

The derivative of the inverse cotangent function is -1/(1+x²).

Using the chain rule, we can find the derivative of h(t) as follows: h'(t) = 17 x(-1/(1+t²)) x(1) + 17 x (-1/(1+(1/t)²)) x (-1/t²)

Simplifying the expression, we get:

h'(t) = -17/(1+t²) + 17/(t² + 1)

Therefore, the derivative of the function h(t) = 17 cot⁻¹(t) + 17 cot⁻¹(1/t) is h'(t) = -17/(1+t²) + 17/(t² + 1).

Step-by-step explanation:

Answer: 529.3 downloads

Explanation:

Standard version size = 2.1 MB

High quality version = 4.7 MB

The high-quality version was downloaded twice as often as the standard version

H = 2 S

The total size downloaded for the two versions = 3335 MB

H + S = 3335

We have the system:

H = 2 S (a)

H + S = 3335 (b)

Put A into B

(2S ) + S = 3335

3S = 3335

S= 3335/3

S= 1,111.67 MB

Divide the total MB of standard versions by the size of each standard version.

1,111.67 / 2.1 = 529.3 downloads

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.

In this scenario, the shape of the sampling distribution of X-bar is approximately normal.

The sampling distribution of the sample mean, X-bar, can be determined by the Central Limit Theorem. In this case, since the sample size is large (n = 64) and the underlying distribution (X) is approximately normal, the sampling distribution of X-bar will also be approximately normal. The Central Limit Theorem states that regardless of the shape of the population distribution, as the sample size increases, the sampling distribution of X-bar tends to become more and more normal. Therefore, in this scenario, the shape of the sampling distribution of X-bar is approximately normal.

When respondents are asked to rank local shopping malls so that their first choice is 1, their second choice is 2, and so forth, this is best described as an example of an ordinal scale.

An ordinal scale is a sort of measuring scale that enables the researcher to rank or arrange the responses in a certain sequence, but it does not reveal the extent of the variations between the replies. In comparison to the nominal scale, the ordinal scale provides a higher degree of measurement because the given numerals serve to both identify the item and denote its place in the ordered list.  

In the given case, the ranking of retail centres which namely first, second, third, etc. are an example of an ordinal scale since it enables us to arrange the replies but does not reveal the precise distinctions between each ranking.

By answering the presented question, we may conclude that If you use a equation different fertiliser with a different dilution rate, you must modify the amount of fertiliser to attain the appropriate concentration.

In mathematics, an equation is an assertion that affirms the equivalence of two factors. An algebraic equation (=) separates two sides of an equation. For instance, the assertion  \("2x + 3 = 9"\) states that the word  \("2x + 3"\) corresponds to the number "9".

The goal of solution solving is to figure out which variable(s) must still be adjusted for the equations to be true. It is possible to have simple or intricate equations, recurring or complex equations, and equations with one or more components.

For example, in the equations  \("x^2 + 2x - 3 = 0,"\) the variable x is lifted to the powercell. Lines are utilized in many areas of mathematics, include algebra, arithmetic, and geometry.

The amount of fertiliser required for three applications of a 3-gallon watering can is determined by the desired fertiliser concentration in the water.

For example, if the suggested dilution rate for a fertiliser is 1 tablespoon per gallon of water, you would need to add 3 tablespoons of fertiliser to the 3-gallon watering can for each application. So, for 3 applications, you would need a total of 9 tablespoons of fertiliser.

Therefore, If you use a different fertiliser with a different dilution rate, you must modify the amount of fertiliser to attain the appropriate concentration.

A(n) "correlational" design is used when the researcher wants to test a relationship between existing variables. This design aims to determine the degree to which two variables are related or associated with each other. In a correlational design, the researcher measures the variables of interest and examines the statistical relationship between them, typically using correlation coefficients.

On the other hand, a(n) "experimental" design is used when a researcher wants to test a causal link between variables. In an experimental design, the researcher manipulates one or more independent variables and measures the effect on a dependent variable. By controlling for confounding variables and using random assignment, an experimental design allows for causal inferences to be made.

It's important to note that while correlational designs can provide valuable insights into the relationships between variables, they do not establish causality. Experimental designs, on the other hand, provide stronger evidence for causal relationships by systematically manipulating variables.

Answer:

He has 1/3 of a jug left.

Step-by-step explanation:

He starts with 1 1/3 jugs.

He uses 3/4 of 1 1/3 jugs.

A full amount is 1 or 4/4. If he uses 3/4, he has 1/4 left since

1 - 3/4 = 4/4 - 3/4 = 1/4

That means he has 1/4 of 1 1/3 jugs left.

We need to multiply 1/4 by 1 1/3.

1/4 * 1 1/3 =

= 1/4 * 4/3

= 4/12

= 1/3

Answer: He has 1/3 of a jug left.

Answer:

$31.104

Step-by-step explanation:

Given :

Regular price = $36

Discount on sale = 20%

Discounted price = (100-20)%*36=0.8*36 = $28.8

Sales tax rate = 8% ;

Tax on sale = 8% * $28.8 = 2.304

Final amount that will have to be paid :

Discounted price + tax on sale

$28.8 + $2.304

= $31.104

Let's start solving this problem by getting first the price of getting 5 items. We have

We then get the amount to be discounted by multiplying the total cost of 5 items with the discount percentage. We have

We then subtract this amount to the total cost of buying the 5 items to get the final answer. We have

FMECA is a bottom-up hardware approach to risk assessment. It is an inductive, or data-driven, linking elements of a failure chain as follows: Effect of Failure, Failure Mode, and Causes/Mechanisms. To estimate the reliability of software, most software prediction models use the probability density function to predict "Mean Time To Failure."

FMECA is a systematic and structured analytical methodology used to identify potential failures in a system, equipment, process, or product, and to assess the effect and probability of those failures. FMECA stands for Failure Modes, Effects, and Criticality Analysis. FMECA is similar to FMEA (Failure Modes and Effects Analysis) in that it is used to identify failure modes and assess their risk.

However, FMECA goes beyond FMEA by analyzing the criticality of each failure mode. This makes it an effective tool for identifying the most significant failure modes and prioritizing them for corrective action. A Probability Density Function (PDF) is a function that describes the likelihood of a random variable taking on a particular value.

PDF is used in software prediction models to estimate the reliability of software by predicting "Mean Time To Failure" (MTTF). MTTF is the average time between failures of a system, equipment, process, or product.

The output of the expression (onescomplement '(0 1 0 2 0 3)) is the list (1 0 1 0 1 0).

Given the scheme code provided, the output of the expression (onescomplement '(0 1 0 2 0 3)) can be determined.
First, let's understand what the code is doing. The code defines two procedures: not-gate and onescomplement.
The not-gate procedure takes an input, x, and checks if it is equal to 0 using the = operator. If x is equal to 0, it returns 1. Otherwise, it returns 0. Essentially, it negates the input value.
The onescomplement procedure takes a list, a-list, as input. It uses the map function to apply the not-gate procedure to each element in the list, creating a new list where each element is the complement of the corresponding element in the input list.
Now, let's evaluate the expression (onescomplement '(0 1 0 2 0 3)) step-by-step:
1. The onescomplement procedure is called with the list '(0 1 0 2 0 3) as input.
2. The map function is applied to the input list, with the not-gate procedure as the function argument. This means that each element in the list will be passed as an argument to the not-gate procedure.
3. The not-gate procedure is applied to each element in the list: 0, 1, 0, 2, 0, and 3.
4. For each element, not-gate checks if it is equal to 0. If it is, it returns 1. Otherwise, it returns 0.
5. The map function returns a new list with the complemented values: (1 0 1 0 1 0).

Answer:

There are 2 solutions to square root x = 9

They are 3, and -3

Step-by-step explanation:

The square root of x=9 has 2 solutions,

The square root means, for a given number, (in our case 9) what number times itself equals the given number,

Or, squaring (i.e multiplying with itself) what number would give the given number,

so, we have to find the solutions to \(\sqrt{9}\)

since we know that,

\((3)(3) = 9\\and,\\(-3)(-3) = 9\)

hence if we square either 3 or -3, we get 9

Hence the solutions are 3, and -3

To determine the minimum score needed to ensure that you are in the top 7%, we need to find the z-score associated with the top 7% and then convert it back to the raw score.

The top 7% corresponds to an area of 0.07 under the standard normal distribution curve. To find the z-score associated with this area, we can use a standard normal distribution table or a calculator.

Using a standard normal distribution table or calculator, we find that the z-score corresponding to an area of 0.07 is approximately 1.4051.

To convert this z-score back to the raw score, we can use the formula:

x = z * standard deviation + mean

Substituting the values into the formula, we get:

x = 1.4051 * 100 + 500

x ≈ 140.51 + 500

x ≈ 640.51

Therefore, the minimum score needed to ensure that you are in the top 7% is approximately 640.51.
