B) (6, 17)

Step-by-step explanation:

y = 3x - 1

To find a solution to the equation

Let x = 6

y = 3*6 -1

y = 18-1

y = 17

One possible solution is ( 6,17)

This is choice B

The median of list of numbers is-2.

Given the list of numbers is 13,15,6,8,-16,2,-12,3,-18,-18.

The median is the median of a sorted list of numbers. To find the median of a sequence of numbers, the numbers must be sorted in order from lowest to highest or highest to lowest.

Firstly, we will arrange the number from ascending to descending, we get

-18,-18,-16,-12,-6,2,3,8,13,15.

Now, we will find the middle term of the sequence, we get

The middle terms are -6 and 2.

Further, we will find the median of it.

n=(-6+2)/2

n=-4/2

n=-2

Hence, the median of the list of numbers 13, 15, -6, 8, -16, 2, -12 ,3 ,-18 ,-18 is -2.

Answer:eq

Step-by-step explanation:

The number of songs that Deante' would have downloaded during month 9 is 58 songs.

A regression line is a statistical line that best describes the behavior of a data set and such, it is a line that best fits a set of data.

By using Microsoft excel to plot the data on a scatter plot, we can logically deduce that line of best fit for the songs downloaded is given by:

y = 2.03x + 39.7

Thus, the number of songs that Deante' would have downloaded during month 9 is:

y = 2.03(9) + 39.7

y = 18.27 + 39.7

y = 57.97 ≈ 58 songs.

Answer:

A) ŷ = 2.03X + 39.73

B) 58

Step-by-step explanation:

A line of best fit is a line drawn on a scatter plot that shows the trend and the best estimation of the relationship between x and y.

After graphing it, it's easy to find the point at which x and why intersect along the line where x is nine.

Using the equation, just replace x with nine and solve.

Answer:

25 people

Step-by-step explanation:

These are the pieces of information we know.

- 1/6 who came to the restaurant ordered fish tacos

- There were 30 customers in total

- We need to find the number of people who did not order fish tacos

1. The number of people who ordered fish tacos can be expressed as: 30 x 1/6, which is 5. We know that 5 people ordered fish tacos.

2. Since we want to know the number of people who didn't want fish tacos, we take 5 away from 30: 30 - 5, which is 25.

25 people did not order fish tacos on Tuesday.

The expected value of the proposition which is the net expected outcome is; $20.89.

We are given that;

There is a deck of cards.

There are 3 kinds of cards that have value under 4 (or equal). These 3 cards are 2, 3, 4 and they are in total 4 * 3 = 12 cards.

The probability that we draw such a card = 12/52 = 0.23.

Thus, the probability that we do not draw such a card = 1 - 0.23 = 0.77.

Now, If we play the game once, we will get 0.23 of the times $208 and 0.77 of the times $35.

Thus, the net total expected outcome is: (0.23*208) - (0.77*35)

= $20.89.

Mark up = $66

Mark up on selling price = 37%

Selling price = 37%

Selling price x Mark up percentage = Mark up

Selling price x 37% = 66

Selling price = $178.38

Cost = Selling price - Mark up

= 178.38-66

= $112.38

Cost as a percentage of selling price = Cost / Selling price

= 112.38/178.38

= 63%

Duadrilateral ABCD has vertices with such coordinates:

A(15,10);

B(15,20);

C(20,15);

D(20,5).

Apply a rotation by 90°counterclockwise around point A to this quadrilateral, then

B(15,20)→B'(5,10);

C(20,15)→C'(10,15);

D(20,5)→D'(20,15).

Second transformation.

The inverse function of [tex]A(b) = 12 \cdot \frac{b + 9}2[/tex] is b(a) = a/6 - 9

The function is given as:

[tex]A(b) = 12 \cdot \frac{b + 9}2[/tex]

Divide 12 by 2

[tex]A(b) = 6 \cdot (b + 9)[/tex]

Rewrite the function as

[tex]a = 6 \cdot (b + 9)[/tex]

Divide both sides by 6

a/6 = b + 9

Subtract 9 from both sides

b = a/6 - 9

Express as a function

b(a) = a/6 - 9

Hence, the inverse function of [tex]A(b) = 12 \cdot \frac{b + 9}2[/tex] is b(a) = a/6 - 9

The intersecting chords theorem or just the chord theorem is a statement in elementary geometry that describes a relation of the four line segments created by two intersecting chords within a circle. It states that the products of the lengths of the line segments on each chord are equal.

Let length of AE be x

By intersecting chords theorem,

AE(ED) = BC(DE)

x(x + 12) = (x +2)(x +5)

x² + 12x= x² + 7x + 10

[tex]\sf x = \dfrac{n - 2mp}{2m}[/tex]

Step-by-step explanation:

              [tex]\sf 3m = m + \dfrac{n}{p + x}\\[/tex]

        [tex]\sf 3m - m = \dfrac{n}{p +x}[/tex]

                [tex]\sf 2m = \dfrac{n}{p +x}[/tex]

Now cross multiply,

          2m*(p +x) = n

To open the parenthesis, multiply 2m by p and x.

        2mp + 2mx = n

 Isolate the term with variable 'x'

                    2mx = n - 2mp

Now, isolate 'x', by dividing both sides by 2m

                          [tex]\sf x = \dfrac{n-2mp}{2m}[/tex]                            

Answer:

x = [tex]\frac{N-2MP}{2M}[/tex]

Step-by-step explanation:

3M = M + [tex]\frac{N}{P+x}[/tex] ( subtract M from both sides )

2M = [tex]\frac{N}{P+x}[/tex] ( multiply both sides by P + x to clear the fraction )

2M(P + x) = N ← distribute parenthesis on left side

2MP + 2Mx = N ( subtract 2MP from both sides )

2Mx = N - 2MP ( divide both sides by 2M )

x = [tex]\frac{N-2MP}{2M}[/tex]

The Answer Is 382...

Step-by-step explanation:

The parent function moves 4 units right and 3 units down. This is a translation by the vector.

According to the question,

Transformation [tex]\sqrt[3]{x}[/tex] maps  onto [tex]\sqrt[3]{x+4} -3[/tex] . Take f(x) =  [tex]\sqrt[3]{x}[/tex] and f(x+4)=[tex]\sqrt[3]{x+4}[/tex].

f(x) =  [tex]\sqrt[3]{x}[/tex]

f(x+4)=[tex]\sqrt[3]{x+4}[/tex]

f(x+4) - 3=[tex]\sqrt[3]{x+4}[/tex] - 3

Analyze the function to see the translations. f(x-4) corresponds to a horizontal translation 4 units in the positive 'x' direction. f(x)-3 corresponds to a vertical translation 3 units in the negative 'y' direction.

Hence, the parent function moves 4 units right and 3 units down. This is a translation by the vector.

Answer:

Step-by-step explanation:

If the base is 20, then 2 of the sides must have a length of 20. This means that the TOTAL length of the remaining sides is 10. (20*2) + (10) = 50. If we divide that in half, we get 5. That is the side length of the remaining 2 sides. This means that 20 * 5 will give us the area (b*h).

Given,

base, b = 20mm &

perimeter, p = 50mm.

the area of the rectangle : (50 – 20 × 2) ÷ 2 = 5. 5 × 20 = 100 [tex]mm^{2}[/tex].

Perimeter and area are two important and basic mathematical subjects. They help quantify the physical space and also provide a more advanced foundation of mathematics in algebra, trigonometry, and calculus. Perimeter is a measure of the distance around a shape, and area indicates how much area the shape covers.
