Answer:

Options B and D

Step-by-step explanation:

Step 1:  Determine what negative association is

Negative association basically means that the best-fit line for the scatter plot would be in a downwards slope which means that it has a negative association.  

In the given examples, Option A wouldn't work because we can see that the best-fit line would be going up which is a positive association.  Option B would work because we see the downward slope.  Option C wond't work for the same reason as Option A.  And finally Option D would work since we have a downward slope.

Answer:  Options B and D

The inverse of the function \(y=\frac{1}{9}x^2\) is \(\sqrt{9x}\)

Given the function \(f(x) = \frac{1}9} x^2\)

We are to find its inverse

Step 1: Ley y = f(x)

\(y=\frac{1}{9}x^2\)

Step 2: Replace y with x

\(x = \frac{1}{9}y^2 \\x = \frac{y^2}{9}\)

Step 3: Make y the subject of the formula

\(9x = y^2\\y^2 = 9x\\\)

Step 4: Take the square root of both sides

\((\sqrt{y})^2 = \sqrt{9x}\\y = \sqrt{9x}\\\\h(x) = \sqrt{9x}\\\)

This shows that the inverse of the function \(y=\frac{1}{9}x^2\) is \(\sqrt{9x}\)

Step-by-step explanation:

A right triangle is a type of triangle with exactly one angle equal to 90°. The other two angles sum up to 90°.

A triangle measures 180°. We plug in the given information from the question above…

90° + 32° = 122°

Applying the Triangle Sum Property…

180° - 122° = 58°

Number sequence

A number sequence is a progression or a list of numbers that are directed by a pattern or rule.

Here,

a₀, a₁, a₂, and a₃ are terms of a sequence

from option a, a\(_{n}\) = \(2^{n}\)+ n

⇒ a₀  = 2⁰+ 0 = 1+0 = 1

⇒ a₁  = 2¹+ 1 = 2+1 = 3

⇒ a₂, = 2²+ 2 = 4+2 = 6

⇒ a₃  = 2³+ 3 = 8 +3 = 11  

from option b, a\(_{n}\) = n^(n+1)!

⇒ a₀  = 0^(0+1)! = 0

⇒ a₁  = 1^(1+1)! = 2² = 2

⇒ a₂, = 2^(2+1)! = 2^(3)! = 2⁶          [ ∵ 3! = 6 ]

⇒ a₃  = 3^(3+1)! = 3^(4)! = 3²⁴         [ ∵ 4! = 24 ]

from option c, a\(_{n}\) =  [n/2]          

⇒ a₀  = [0/2] = 0

⇒ a₁  = [1/2] = 1/2

⇒ a₂, = [2/2] = 1

⇒ a₃  = [3/2] =  3/2  

from option d, a\(_{n}\) = [n/2] + [n/2]

⇒ a₀  =  [0/2] + [0/2] = 0

⇒ a₁  =  [1/2] + [1/2] = 1/2 + 1/2 = 1

⇒ a₂, = [2/2] + [2/2] = 1 + 1 = 2

⇒ a₃  =  [3/2] + [3/2] = 6/4 = 3/2

The total revenue that will be maximized is 20 - 2a

From the question, we have the following parameters that can be used in our computation:

Qd = 20 - P

The revenue equation is calculated using

Revenue = Quantity * Price

So, we have

R = Qd * P

This gives

R = (20 - P) * P

Expand

R = 20P - P²

Differentiate

R' = 20 - 2P

Next, we have

Q = a

So, we have

R = 20 - 2a

Hence, the total revenue that will be maximized is 20 - 2a

The equation of the line perpendicular to y = 6x -2 and passes through (6, -2) is y = - 1 / 6 x - 1

The equation of a linear graph can be represented in slope intercept form.

Therefore,

y = mx + b

where

Therefore,  the equation of the line is perpendicular to y = 6x -2 and passes through (6, -2).

Perpendicular lines follows the rule below:

m₁ m₂ = -1

6m₂ = -1

m₂ = - 1 / 6

Therefore, let's find the y-intercept using (6, -2)

y = - 1 / 6 x + b

-2  = - 1 / 6 (6) + b

- 2 + 1 = b

b = -1

Therefore, the equation of the line is y = - 1 / 6 x - 1

Answer:

Permanent Magnets and Electromagnets: What are the Differences? A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field. ... An electromagnet is made from a coil of wire which acts as a magnet when an electric current passes through it.

Step-by-step explanation:

Electromagnets differ from regular magnets in that they require an electric current to generate a magnetic field.

Regular magnets, also known as permanent magnets, possess an inherent magnetic field due to the alignment of their atomic or molecular structure. They do not require an external power source.

On the other hand, electromagnets are made by wrapping a coil of wire around a magnetic core and passing an electric current through the wire. The electric current creates a magnetic field, and the strength of the magnetic field can be controlled by varying the current.

One key advantage of electromagnets is their ability to be turned on and off by controlling the electric current. This feature allows for a wide range of applications, such as in electric motors, generators, speakers, magnetic levitation systems, and more, where the magnetic field needs to be controlled or modulated. In contrast, regular magnets have a constant magnetic field that cannot be easily manipulated.

Answer:

A, C,

Step-by-step explanation:

The time that elapses from the start of the green indication to the end of the red indication for the same phase of a signalized intersection is called the phase length, while any part of the cycle length during which signal indications do not change is called an interval.

There are four kinds of intervals that constitute a complete traffic signal cycle: phase interval, clearance interval, all-red interval, and pedestrian interval.

The duration of each signal interval is referred to as its time length.

The effective capacity of signalized intersections, according to HCM 2000, is a function of cycle length. Long cycle lengths (more than 120 seconds) result in reduced capacity.

As a result, cycle length should be kept as short as feasible in order to maximize capacity.

Short cycle lengths, on the other hand, reduce the capacity of a signalized intersection since there is less time for each phase to service traffic.

Answer:

(x + 1)(x + 2) is divisible by 3.

Step-by-step explanation:

Assume that x is not divisible by 3. This means that x can be expressed as x = 3k + r, where k is an integer and r is the remainder when x is divided by 3. Since x is not divisible by 3, the remainder r must be either 1 or 2.

Case 1: r = 1

If r = 1, then x = 3k + 1. Now let's consider (x + 1)(x + 2):

(x + 1)(x + 2) = (3k + 1 + 1)(3k + 1 + 2)

= (3k + 2)(3k + 3)

= 3(3k^2 + 5k + 2)

We can see that (x + 1)(x + 2) is divisible by 3.

Case 2: r = 2

If r = 2, then x = 3k + 2. Now let's consider (x + 1)(x + 2):

(x + 1)(x + 2) = (3k + 2 + 1)(3k + 2 + 2)

= (3k + 3)(3k + 4)

= 3(3k^2 + 7k + 4)

We can see that (x + 1)(x + 2) is divisible by 3.

Hence, the statement is proven.

Answer:

Step-by-step explanation:

An absolute value is never negative.

Correct choice is C

Danielle spent x dolar on lunch.

Three times as much on transportation, which can be written as 3x

Then,$4 less on a book that she did on transportation, so 3x-4

If she spent $59, we can equal all the expressions to this value.

Therefofore:

x + (3x) +(3x-4) = 59

To find how much she sped on lunch, we need to solve for x:

x + 3x + 3x - 4 = 59

Solve the like terms:

7x -4 = 59

Add both sides 4 units:

7x -4 +4 = 59 + 4

7x = 63

Divide both sides by 7:

7x/7 = 63/7

x = 9

Hence, Danielle spent $9 dollars on lunch.

The implied dependencies are 3 and 4. We can use Armstrong's inference rules to determine which of the dependencies are implied by the given functional dependencies:

Reflexivity: For any set of attributes X, X → X (Trivial functional dependency).

Augmentation: If X → Y, then XZ → YZ for any Z.

Transitivity: If X → Y and Y → Z, then X → Z.

Using these rules, we can determine that:

A → AD: This is not implied by the given functional dependencies since AD is not a subset of A.

A → DH: This is not implied by the given functional dependencies since DH is not a subset of A.

AED → C: This is implied by transitivity since AED → H (by AE → H) and H → E (given), and E → C (given), therefore AED → C.

DH → C: This is implied by transitivity since DH → BC (given) and BC → C (trivial), therefore DH → C.

ADF → E: This is not implied by the given functional dependencies since E is not a subset of ADF.

Therefore, the implied dependencies are 3 and 4.

The conclusion that is correct in a two-tailed test at α = .05 is There appears to be no difference in the mean occupancy rates.

From the given values:

Thus, the P-value = 0.1791

Interpret results. Since the P-value (0.1791) is greater than the significance level (0.05), we failed to reject the null hypothesis.

From the above test, we do not have sufficient evidence in favor of the claim that there is a difference in the mean occupancy rates.
