Using the formula of slope of a line, the slope in the graph is -2/3

The slope of a line is defined as the change in y-coordinate with respect to the change in x-coordinate.

The net change in y-coordinate is represented by Δy and the net change in x-coordinate is represented by Δx.

Hence, the change in y-coordinate with respect to the change in x-coordinate is given by the formula

m = y₂ - y₁ / x₂ - x₁

Taking two coordinate from the line;

Substituting the values into the formula below

m = y₂ - y₁ / x₂ - x₁

m = 0 - 4 / 6 - 0

m = -4 / 6

m = -2/3

The slope is -2/3

The linear function that represents c, the total cost, when x tickets are ordered is

c=5.50+20.50x

A mathematical statement known as an equation is made up of two expressions joined together by the equal sign. A formula would be 3x - 5 = 16, for instance. When this equation is solved, we discover that the value of the variable x is 7.

There are three major forms of linear equations: point-slope form, standard form, and slope-intercept form.

Let

The overall price is c.

the quantity of tickets, x

the price of one ticket, excluding service charges, is z.

Knowing this

108=5.50+5z

finding z

z=20.50

The horizontal asymptote of function f(x) is y=6.5, which is a straight line, which means that even if time is infinite, the pH of the mouth will not rise above 6.5, which is the normal pH of the mouth.

A function's horizontal asymptote is a horizontal line with which the function's graph appears to coincide but does not actually coincide. The horizontal asymptote is used to determine the behavior of the function.

When either lim x f(x) = k or lim x - f(x) = k, the horizontal asymptote of a function y = f(x) is a line y = k. . It is commonly abbreviated as HA. In this case, k is a real number that the function approaches when x is extremely large or extremely small.However, the maximum number of asymptotes that a function can have is 2.

Given,

[tex]f(x)=\frac{6.5x^2-89.4x+3734}{x^2+576}[/tex]

The horizontal asymptote of the function f(x) can be determined by

[tex]y=\lim_{x \to \infty} f(x)\\\\=\lim_{x \to \infty}\frac{6.5x^2-89.4x+3734}{x^2+576}\\\\=\lim_{x \to \infty}\frac{x^2(6.5-\frac{89.4}{x}+\frac{3734}{x^2})}{x^2(1+\frac{576}{x^2})}\\\\=\lim_{x \to \infty}\frac{(6.5-\frac{89.4}{x}+\frac{3734}{x^2})}{(1+\frac{576}{x^2})}\\\\=\frac{(6.5-\frac{89.4}{ \infty}+\frac{3734}{ \infty})}{(1+\frac{576}{ \infty})}\\\\=\frac{6.5-0+0}{1+0}\\\\=\frac{6.5}{1}=6.5[/tex]

Thus, the horizontal asymptote of function f(x) is y=6.5 which is straight line which means even the time reaches infinity the pH of mouth will not increase more than 6.5, which is the normal pH of mouth.

Answer:

  5/72

Step-by-step explanation:

You want the probability of rolling a 6-sided die 3 times with the sequential outcomes 3, not 3, even number.

The probability of any given sequence of outcomes is the product of the probabilities of the outcomes individually. (We assume independence.)

  P(3) = 1/6

  P(not 3) = 1 -P(3) = 5/6

  P(even) = 1/2

Then the probability of the given sequence is ...

  P(3, 3', even) = (1/6)(5/6)(1/2) = 5/72

The probability of the given sequence is 5/72.

Out of the 750 registered voters in the precinct, 480 people actually voted in the primary selection.

We have 750 registered voters in one precinct and in a primary selection 64 out of 100 voters actually voted.

Out of 100 people, only 64 voted. So, the percentage of people voted can be calculated as follows -

64 = x% of 100

64 = x/100 x 100

x = 64%

So -

64% 0f 750

(64/100) x 750

480

Therefore, 480 people out of 750 registered voters in one precinct actually voted.

The values of unknown measures are m∠C'B'D' = 95°,  CQ = 6 and B'D' = 11

We are given that triangle BCD was dilated using the rule d subscript q, one-half.

Since the sum of the measure of all the angles in a triangle is 180°.

m∠C'B'D = 180° - m∠B'C'D' - m∠B'D'C'

m∠B'C'D = m∠BCD, m∠B'D'C' = m∠BDC  (by dilation)

m∠C'B'D = 180° - 34° - 51° = 95°

[tex]\frac{B C}{B^{\prime} C^{\prime}}=\frac{B D}{B^{\prime} D^{\prime}}=\frac{36}{18}=2[/tex]

[tex]B^{\prime} D^{\prime}=\frac{1}{2} B D[/tex]

A midpoint of a line segment is the point on a segment that bisects the segment into two congruent segments.

The formula to find the midpoint of line segment is (x, y) = [(x1+x2)/2, (y1+y2)/2]

From the given figure, the coordinates are A(-6x, 4y) and B(-2x, -4y) and C(8x, -2y)

As the ticket prices at an outdoor theatre performance are $2.50 for children and $5.00 for adults. one evening, $6350 is collected from a total of 1900 people attending. There are 640 adult and 1260 childrens.

Given in the questions:

Ticket price in outdoor Theater = $2.50

For Children = $5.00

Total tickets collected in evening = $6350(collected from 1900 people)

Let p be the adult and

1900 - p be the children's who attained the show.

Now,

   2.5 × (1900- p) +5p = 6350

⇒ 4750 - 2.5p +5p =6350

⇒ 2.5p = 1600

⇒ p = 1600/2.5

⇒ p = 640

Since,

p = 640

Therefore,

   1900 - p = children

⇒ Children = 1900 - 640

⇒ Children = 1260

Therefore, there are total 640 adults and 1260 children's in the theater.

The popcorn box in a shape of a rectangular prism will thus have a length of 0.3 inches in inches.

A three-dimensional solid form with six faces, including rectangular bases, is called a rectangular prism.

A rectangular prism also refers to a cuboid.

A cuboid and a rectangular prism have the same cross-section.

Quadrilaterals make up its faces.

So, a popcorn box's volume is modeled by Gabriel as a right rectangular prism, and a full box can store 74 cubic inches of popcorn.

Its height is 77 in, and its breadth is 3 1/2 in.

Then, the prism's width will be:

W =  3 + 1/2

W = 7/2

Consequently, the popcorn box's length in inches will be:

V = LWH

74 = L * 7/2 * 77

( 8,23 ) is represented in the slope intercepted form as y = x + 15

When you know the slope of the line to be investigated and the given point is also the y intercept, you can utilise the slope intercept formula,

y = mx + b. (0, b) The symbol b in the formula stands for the y value of the y intercept point.

According to the given information

We are given with two points

[tex](x_{1} ,y_{1} )[/tex] = (4,19)

[tex](x_{2},y_{2})[/tex] = ( 8,23 )

So

Now we need to find the slope of the given line having the above coordinate points

m = [tex]\frac{y_{2} -y_{1} }{x_{2}-x_{1} }[/tex]

Putting the values

We get

m = [tex]\frac{23-19}{8-4}[/tex]

m = [tex]\frac{4}{4}[/tex]

m = 1

Equation of line passing through points [tex](x_{1} ,y_{1} )[/tex] = (4,19) and having

slope = 1

[tex]y-y_{1} = m(x-x_{1})[/tex]

y - 19 = x - 4

y = x + 15

The equation of line passing through points [tex](x_{1} ,y_{1} )[/tex] = (4,19) and [tex](x_{2},y_{2})[/tex] =

Answer:

  A

Step-by-step explanation:

You want to select the scatter plot with strong positive correlation.

Correlation is a measure of how well one variable's values track the values of another variable. Perfectly correlated variables will have a scatter plot that is a straight line. The sign of the correlation (positive, negative) matches the sign of the slope of the line.

The less correlated values are, the more their scatter plot looks like a random placement of points. When there is no correlation at all, knowing the value of one of the variables gives no clue about the value of the other one.

Computed values of correlation range from -1 to +1.

When the plot begins to resemble a line with positive slope, the variables plotted in the scatter plot have strong positive correlation. That is shown in the attached scatter plot.

If a  traveler is walking on a moving walkway airport. The traveler's speed off the walkway is 5 ft/sec and the speed of the moving walkway is 3 ft/sec.

Speed can simply be defined as how fast an object move.

Let w represent the walkway's speed in ft/sec

So,

t-w =2

t+w=8

Add the equation

Divide both side by 2t

t= 10/2

t=5fr/sec ( traveler's speed )

Speed of moving walkway
