Answer:

-1/16

Step-by-step explanation:

Answer: 1/8 + -3/16 = -1/16

Step-by-step explanation:

First, multiply the numerator and denominator of 1/8 by 2.

1/8 + -3/16

1 x 2 = 2

8 x 2 = 16

2/16 + -3/16

Next, turn the + and - into one -.

2/16 + -3/16

2/16 - 3/16

Finally, solve 2/16 - 3/16! We will get a negative number.

2/16 - 3/16 = -1/16

1/8 + -3/16 = -1/16

The assumption necessary to apply a goodness-of-fit test is that the data are measured with a nominal or ordinal scale.

Goodness-of-fit tests are used to determine whether an observed frequency distribution of categorical data fits an expected theoretical distribution. They compare the observed frequencies with the expected frequencies based on a specified distribution. The data being analyzed using a goodness-of-fit test are typically categorical, such as counts or proportions in different categories or groups.

Therefore, the correct answer is: The data are measured with a nominal or ordinal scale.

Placing the students in order from fastest to slowest, in terms of who has the fastest water filling rate is;

1. Miles

2. Dubem

3. Hayden

The way the fastest rate is determined is by finding the unit rates

A unit rate (or unit ratio) is a ratio that describes how many units of the first type of quantity corresponds to one unit of the second type of quantity.

Now, from the question, the rate would clearly be number of walls filled per minute.

1) Mills fills his wall at a rate of 12 wall in 9 minutes. Thus;

Mills unit rate = 12/9 = 4/3 walls filled per minute = 1.333 walls filled per minute

2) Hayden can fill his wall at 15 wall in 313 minutes. Thus;

Hayden's unit rate = 15/313 walls filled per minute = 0.0479 walls filled per minute

3) Dubem can cover 49 wall in 638 minutes. Thus;

Dubem's unit rate = 49/638 walls filled per minute = 0.0768 walls filled per minute

Looking at the decimal unit rates, we can see that fastest to slowest in order are;

1. Miles

2. Dubem

3. Hayden

The way I knew who was faster was to look at the decimal values of their unit rates and it is seen that Miles covered the most part of wall in one minute

Answer:

\(y'' = 8\sin(x) + 16x\cdot \cos(x) - 4x^2 \cdot \sin(x)\)

Step-by-step explanation:

Given the function:

\(y=4x^2 \cdot \sin(x)\)

We can find its derivative, or instantaneous slope, by applying the power rule and using the common derivative of the trigonometric function sine within the product rule.

Here are the relevant formulas:

First, we can find the derivative of each of the function's factors [ which I will label \(f(x)\) and \(g(x)\) ].

\(f(x) = 4x^2\)

↓ applying the power rule \((x^a)' = ax^{a\, - \, 1}\)

\(f'(x) = 4(2x^{2-1})\)

\(\bold{f'(x) = 8x}\)

⎯⎯⎯⎯⎯⎯⎯

\(g(x) = \sin(x)\)

↓ applying the common derivative \((\sin(x))' = \cos(x)\)

\(\bold{g'(x) = \cos(x)}\)

Now, we can apply the product rule using these values of \(f'(x)\) and \(g'(x)\).

\(\left(\dfrac{}{} f(x) \cdot g(x) \dfrac{}{} \right)' = f(x)\cdot g'(x) + g(x) \cdot f'(x)\)

\(y' = 4x^2 \cdot \cos(x) + \sin(x) \cdot 8x\)

\(\boxed{y' = 4x^2 \cdot \cos(x) + 8x \cdot \sin(x)}\)

To find the second derivative of the function, we have to take the derivative of the derivative. We can apply the same concepts from the previous step, but also with the sum/difference rule.

↓ applying the sum/difference rule to the function's derivative

\(y'' = \left(\dfrac{}{}4x^2 \cdot \cos(x)\dfrac{}{}\right)' + \left(\dfrac{}{}8x \cdot \sin(x)\dfrac{}{}\right)'\)

↓ applying the product rule to each derivative

\(y'' = \left(\dfrac{}{} 4x^2 \cdot (-\sin(x)) + \cos(x) \cdot 8x \dfrac{}{}\right) + \left(\dfrac{}{} 8x \cdot \cos(x) + \sin(x) \cdot 8 \dfrac{}{}\right)\)

↓ combining like terms

\(\boxed{y'' = 8\sin(x) + 16x\cdot \cos(x) - 4x^2 \cdot \sin(x)}\)

The given relation is not a function, and the range is {−2, 0, 1, 3, 4}. In a function, each input (x-value) can only be associated with a single output (y-value).

However, in the given relation, we can see that for the input value of -2, there are two different output values: -2 and 4. This violates the definition of a function, making the relation not a function. The range of a relation or function refers to the set of all possible output values. By examining the given relation, we can observe that the y-values -2, 0, 1, 3, and 4 are present. These are the distinct output values from the relation, and therefore, the range of the relation is {−2, 0, 1, 3, 4}.

A) 24 machines, working simultaneously and independently at this constant rate, can produce a total of 3x units of product P in 4 days..

Let's analyze the given information and use it to determine the number of machines required to produce 3x units of product P in 4 days.

We are told that 4 machines can produce a total of x units of product P in 6 days. This means that the rate at which these 4 machines produce the product is x/(4 * 6) units per day.

To find the number of machines required to produce 3x units of product P in 4 days, we can set up a proportion based on the rates:

(x units / (4 machines * 6 days)) = (3x units / (N machines * 4 days))

Simplifying the proportion:

1/(4 * 6) = 3/(N * 4)

Multiplying both sides by 4:

1/24 = 3/N

Cross-multiplying:

N = 24/1

N = 24

Therefore, the number of machines required to produce 3x units of product P in 4 days is 24.

The answer is option A. 24.

Given that an auditing software can identify 63.7% of misreporting issues in accounting ledgers. Let X be the number of accounting misreporting transactions identified by the software among 50 randomly selected transactions for the last 3 months.Probability that no misreported transactions are found:X follows a binomial distribution with n = 50 and p = 1 - 63.7% = 36.3%.P(X = 0) = (1 - p)^n = (1 - 0.637)^50 ≈ 0.0002Probability that less than 10 misreported transactions are found:

P(X < 10) = P(X ≤ 9)P(X ≤ 9)

= P(X = 0) + P(X = 1) + P(X = 2) + ... + P(X = 9)P(X ≤ 9)

= ∑_(i=0)^9 (50C_i ) (0.363)^i (1 - 0.363)^(50 - i) ≈ 0.99

Probability that at least half of the transactions are misreported:

Step-by-step explanation:

Option 4 - Survey 100 randomly selected parents in the theme park - produces an unbiased, representative sample of the population because it selects individuals randomly from the population.

This ensures that everyone in the population has an equal chance of being selected for the survey, which minimizes bias and produces a sample that is more representative of the entire population. The other options may introduce bias because they only survey specific groups of customers or use a non-random sampling method.

To obtain an unbiased, representative sample of the population in the theme park, the best sampling method would be option 2) Survey every 30th customer to enter the theme park.

Answer:

There are 5 quarters and 1 nickel

Step-by-step explanation:

Let Q and N be the numbers of Quarters and Nickels that Senor Pena found, respectively.

The value of each coin is $0.25 for quarters and $0.05 for each nickel

The total of $1.30 would be the result of:

1)  Quarters:  $0.25*Q, and

2)  Nickels:  $0.05*N

So we can write:  $0.25*Q + $0.05*N = $1.30

We also know he found 6 coins, so:

 Q + N = 6

We have two equations and two unknowns.  We can use substitution to find the answer.

Rearrange the second equation to isolate one of the two variables.  lets isolate Q:

  Q = 6-N

We can use this definition of Q in the first equation by substitution:

$0.25*Q + $0.05*N = $1.30

$0.25*(6-N) + $0.05*N = $1.30

Leaving off the $ signs for clarity:

0.25(6-N) + 0.05N = 1.30

1.5 - 0.25N + 0.05N = 1.30

-0.2N = -0.20

   N = 1

There is 1 nickel

Since  Q = 6-N, Q = 5

There are 5 quarters and 1 nickel

CHECK

Do 5 quarters and 1 nickel add to $1.30?

5*($0.25) + 1*($0.05) = $1.30?

$1.25 + $0.05 = $1.30  YES
