Step-by-step explanation:

Answer:

Scatter plots show how much one variable is affected by another. The relationship between two variables is called their correlation . ... The closer the data points come when plotted to making a straight line, the higher the correlation between the two variables, or the stronger the relationship.

Answer: -1 is not in the domain and 0 and 2 are in the domain

Step-by-step explanation:

The domain of the function g(x) = “8x” is all real numbers, as there are no restrictions on the values that x can take.

The question seeks to find the domain of a function represented as g(x) = “8x. A function's domain refers to all the possible values that can be input into the function. In the case of g(x) = “8x, this is a linear function where x can take any real number value since there are no restrictions like square roots or denominators that could potentially exclude certain x values. Therefore, the domain of g is all real numbers, often represented as (-∞, +∞) or ℝ in set notation.

P.S. Hello from Russia :^)

Answer: No her plates will not fit in the box

Step-by-step explanation: Each plate is 0.5 inches tall; therefore, the stack of 8 plates will have a height of .

Also, the diameter of the largest plate is 10 inches or has a radius of 5 inches, which matches the radius of the cylindrical box; therefore, we know that the stack of plates can fit into the base area of the cylindrical box.

What we want to figure out now is the height of the cylindrical box to see if it is greater than or equal to 4 inches—the height of the stack of plates.

The volume of a cylinder is , and since for our cylindrical box the volume is 150 cubic inches; therefore,

putting in  and solving for height  we get

,

which is not greater than 4 inches, which means the plates will not fit into the box since the height of the stack is greater than the height of the box.

Answer:

  PLATINUM = 11

Step-by-step explanation:

It appears that the "code" is that vowels count 2 and consonants count 1.

  GOLD = 1 for GLD +2 for O = 3+2 = 5

  LEAD = 1 for LD +2 for EA = 2 +4 = 6

  SILVER = 1 for SLVR +2 for IE = 4 +4 = 8

  URANIUM = 1 for RNM +2 for UAIU = 3 +8 = 11

  PLATINUM = 1 for PLTNM +2 for AIU = 5 +6 = 11

The missing number is PLATINUM =15

A sequence in mathematics is an enumerated collection of items in which repetitions are permitted and order is important.

Given that, GOLD = 5, LEAD = 6, SILVER = 8, URANIUM = 11, PLATINUM = ? from the given data we can see its in a sequence let say GOLD=5

so adding natural number (1, 2, 3, 4, ...) in the sequence will give next valueGOLD = 5LEAD = 5+1=6SILVER = 6+2=8URANIUM = 8+3=11

therefore, PLATINUM = 11+4=15

Step-by-step explanation:

Here you're being asked to solve the given equation 49w^2-4=0 for w with the hint that the solutions are fractions.

49w^2-4=0 is the product of the sum and difference of two squares:

(7w - 2)(7w + 2) = 0

Setting each factor equal to zero and solving for w, we get:

{-2/7, 2/7} as the solutions.

Answer:

B

Step-by-step explanation:

Given

3x² + 21x + 18 ← factor out 3 from each term

= 3(x² + 7x + 6) ← factor the quadratic

Consider the factors of the constant term (+ 6) which sum to give the coefficient of the x- term (+ 7)

The factors are + 6 and + 1, since

6 × 1 = 6 and 6 + 1 = 7, thus

x² + 7x + 6 = (x + 6)(x + 1)

Thus

3x² + 21x + 18 = 3(x + 6)(x + 1) → B

Answer:

D

10

Step-by-step explanation:

The requried Rocco can wear his shirts with jeans in 10 different ways. The correct answer is 10.

To determine the number of different ways Rocco can wear his shirts with jeans, we need to multiply the number of options for shirts by the number of options for jeans. In this case, Rocco has 5 different shirts and 2 different pairs of jeans.

Since he can wear any shirt with any pair of jeans, the total number of different combinations is obtained by multiplying the number of shirts (5) by the number of jeans (2):

5 shirts * 2 pairs of jeans = 10 different ways

Therefore, Rocco can wear his shirts with jeans in 10 different ways. The correct answer is 10.

Answer:

Saving=£450

Spent=£200

Step-by-step explanation:

Ratio of saving to spending is 9:4

She inherits £650

So to determine her saving

It will be

9+4=13

Since her saving is 9

So, 9/13 × 650

5850/13

=450

So her saving is£450

To determine what she spent

4/13 × 650

2600/13

200

Saving=£450

Spent=£200

The amount she saves is  £450 and the amount she spends is £200.

Step-by-step explanation:

Given,

The amount she has = £650

The ratio of saving to spending money is 9:4

To find the amount she saves and she spends.

Let,

The amount she saves = 9x

The amount she spends = 4x

According to the problem,

9x+4x = 650

or, 13x = 650

or, x = [tex]\frac{650}{13}[/tex] = 50

Hence,

The amount she saves =  £50×9 =  £450

The amount she spends = £50×4 = £200

x²-16 -----> (x+4)(x-4).

Step-by-step explanation:

It's an example of what you should be writing depending on your answer. You did not include any details about your question.

The polynomial that is a difference of squares will be x²-16. It is factored as (x+4)(x-4).

Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order. Polynomials are used in management, computer, and math-based occupations. Variables and constants are utilized to define numbers that are known and unknown in expressions in all professions that need proficiency with polynomials.

We have to define a polynomial that is a difference of squares we have to also do factors for that polynomial.

The polynomial that is a difference of squares is found as,

x²-16

Used the below identity in order to factorize the polynomial,

a²-b²=(a+b)(a-b)

16 in its square form is written as 4².

x²-4² = (x+4)(x-4)

Thus, the polynomial that is a difference of squares will be x²-16. It is factored as (x+4)(x-4).

Answer:

Step-by-step explanation:multiply then round

Answer: The equation is y = 0.25/(x - 4) + 3

Step-by-step explanation:

If we have a function y = f(x)

A compression means that we multiply the function by a factor smaller than 1.

Then the vertical compression by a factor of 0.25 is:

y = 0.25*f(x)

a translation by A units to the right, means that we need to valuate the function in x - A.

So now we have:

y = 0.25*f(x - 4)

A translation in the y-axis means that we need to add a constant to the equation, then if we tralate it by 3 units up, we have:

y = 0.25*f(x - A) + 3

Then, if f(x) = 1/x

Our new equation is:

y = 0.25/(x - 4) + 3

Answer:

g ( x ) = 0.25 / ( x - 4 ) + 3

Step-by-step explanation:

Solution:-

- The given function is defined as an inverse function:

                           f ( x ) = 1 / x

- The transformation on the function of f ( x ) are of three kinds. We will use a general form to look at the effect of each transformation.

             [tex]f ( x ) --- > g ( x ) = [ \frac{a}{( x +/- b)} ] + c[/tex]

Where a,b, and c are constants for transformation.

- The effect of constant a:

            a > 1 ------ > Flattens the graph  

            0 < a < 1 -------- > Compresses the graph vertically

- The effect of constant b:

            b > 0 ------ > Horizontal shift to left

            b < 0 -------- > Horizontal shift to right

- The effect of constant c:

            c > 0 ------ > Vertical shift up

            c < 0 -------- > Vertical shift down

- Now we will determine the result of function after each transformation.

                        k ( x ) = 0.25 / x

                      j ( x ) = 0.25 / ( x - 4 )

                     g ( x ) = 0.25 / ( x - 4 ) + 3

Hence, the resulting function of all the mentioned transformations of original function f ( x ) is given as g ( x ):

                    g ( x ) = 0.25 / ( x - 4 ) + 3
