An equation is formed of two equal expressions. The value of the constant of proportionality is 0.41.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given there exists a proportional relationship between the number of juice bottles bought, j, and the total cost in dollars and cents. Therefore,

c ∝ j

c = kj

As the relation is represented by the equation c=0.41j. Therefore, the value of the constant of proportionality is 0.41.

Answer:

The linear equation for the line which passes through the points given as (1,5) and (4,11), is written in the point-slope form as y=2x+3.

Step-by-step explanation:

A condition is given that a line passes through the points whose coordinates are (1,5) and (4,11).

It is asked to find the linear equation which satisfies the given condition.

Step 1 of 2

Determine the slope of the line.

The points through which the line passes are given as (1,5) and (4,11). Next, the formula for the slope is given as,

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

Substitute 11&5 for [tex]$y_{2}$[/tex] and [tex]$y_{1}$[/tex] respectively, and [tex]$4 \& 1$[/tex] for [tex]$x_{2}$[/tex] and [tex]$x_{1}$[/tex] respectively in the above formula. Then simplify to get the slope as follows,

[tex]$$\begin{aligned}m &=\frac{11-5}{4-1} \\m &=\frac{6}{3} \\m &=2\end{aligned}$$[/tex]

Step 2 of 2

Write the linear equation in point-slope form.

A linear equation in point slope form is given as,

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

Substitute 2 for [tex]$m, 1$[/tex] for [tex]$x_{1}$[/tex], and 5 for [tex]$y_{1}$[/tex] in the above equation and simplify using the distributive property as follows,

[tex]$$\begin{aligned}&y-5=2(x-1) \\&y-5=2 x-2 \\&y=2 x-2+5 \\&y=2 x+3\end{aligned}$$[/tex]

This is the required linear equation.

Answer:

2300

Step-by-step explanation:

53%=1219

100=X

X=[(1219)(100)]/53=2300

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Required percentage value = a

total value = b

Percentage = a/b x 100

53% = 1219

100% = 2300

The total number of seats in the theater is 2300

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Number of seats filled by all the students = 1219

1219 is 53% of the total seats in the theater.

This means,

53% = 1219

Now,

Total number of seats in the theater = 100%

53% = 1219

Multiply 100/53 on both sides.

100/53 x 53% = 100/53 x 1219

100% = 2300

Thus,

The total number of seats in the theater is 2300

The equation of the parabola in standard form whose vertex is (0, 0) and a focus along the negative part of the x-axis is equal to x² = - 6 · y. (Correct choice: D)

In accordance with the statement, we find that the parabola has its vertex at the origin, therefore it is horizontal and its vertex constant (C) is negative as its focus is in the negative part of the x-axis. Therefore, the equation of the parabola in standard form has the following form:

x² = C · y, for C < 0.     (1)

The transformed function is:

The parent function is:

[tex]f(x) = x^2 + 2x[/tex]

Here the axis of symmetry is at:

[tex]x = -2/2*1 = -1[/tex]

So first we need to apply a horizontal compression by a factor of 3 with respect to the line x = -1.

Here we can, for the moment, define a new variable that is zero when x = -1, let's define:

z = x + 1.

x = z - 1

Writing our function in terms of z, we get:

[tex]f(z) = (z - 1)^2 + 2*(z - 1)[/tex]

Now we can apply a compression by a factor of 3 around the origin. Then we have:

[tex]f(z/3) = (z/3 - 1)^2 + 2*(z/3 - 1)[/tex]

Returning to the original variable, we have:

[tex]f((x+1)/3) = ( (x + 1)/3 - 1)^2 + 2*( (x + 1)/3 - 1)[/tex]

Now we want to shift it one unit to the right, then we have:

g(x) = f( (x + 1)/3 - 1)

Replacing the actual function we get:

The recursive function of a ball with a 67% rebound is a(n) = 0.67a(n-1)

The rebound is given as:

r = 67%

Express as decimal

r = 0.67

So, the recursive function is:

a(n) = Previous height * r

This gives

a(n) = a(n-1) * 0.67

Evaluate

a(n) = 0.67a(n-1)

Hence, the recursive function is a(n) = 0.67a(n-1)

Basketball

The initial height is given as:

a(1) = 54

So, we have:

a(2) = 0.67 * 54 = 36.18

a(3) = 0.67 * 36.18 = 24.24

Tennis ball

The initial height is given as:

a(1) = 58

So, we have:

a(2) = 0.67 * 58 = 38.86

a(3) = 0.67 * 38.86 = 26.04

Table-tennis ball

The initial height is given as:

a(1) = 26

So, we have:

a(2) = 0.67 * 26 = 17.42

a(3) = 0.67 * 17.42 = 11.67

Hence, the complete table is:

Bounce               n             Height

Let  x be the number of guests.

              18x = 150 + 15x

        18x -15x = 150

                3x  = 150

Answer:

{x | x > -4}

Step-by-step explanation:

{a few basic reminders:  > means greater than; < means less than; ≥ means greater than or equal to; ≤ means less than or equal to

for example: 4 < 7

                     4 ≤ 4

                     4 ≥ 3

                     4 > 3}

When we see an inequality, such as 9x > -36, we are trying to figure out what possible numbers x can be to make this statement true.

We can either use logic / words (see below), or in a much more efficient manner, we can solve this algebraically [as though it were an equation]

So, like when working with any other variable, we want to isolate x:
9x > -36

÷9    ÷9

   x > -4  

just in case none of this makes sense (it can be quite confusing at first),

here's how we can think about it logically

we know that whatever multiplies with 9 must be more than -36, and because -4 multiples with 9 to be exactly -36, any number greater than -4 also will be greater than -36

meaning that x must be more than -4, which we express as: x > -4

So, the solution set (solution set means set of possible solutions) is

{x | x > -4}

The number is 5 if two increased by a number is a dozen. In other words, the correct answer is 5 by solving equations.

Step 1: Write the given information as an equation. "Two increased by a number" can be represented as 2 + x, where x is the unknown number.

Step 2: Translate "Two increased by a number is a dozen" into an equation. The word "a dozen" refers to the number 12.

[tex]2 + x = 12.[/tex]

Step 3: Solve the equation for x. To isolate x, subtract 2 from both sides of the equation:

[tex]2 + x - 2 = 12 - 2.[/tex]

This simplifies to x = 10.

Step 4: Verify the solution. Substitute the value of x back into the original equation:

2 + 10 = 12.

This equation is true, so x = 10 is indeed the solution.

Therefore, the number is 10.

The probability that more than 210 people will pass in front of his store is 0.2272.

In the question, we are given that a coffee shop owner wants to examine the number of customers who pass in front of his store in the morning from 7:00 A.M to 7:30 A.M.

We are asked to find the probability that more than 210 people will pass in front of his store if the mean number of customers during this time is 210.

This experiment follows a Poisson Distribution with a mean (λ) = 200, and the random variable X = 210.

To find the probability that more than 210 people will pass in front of his store, we will find P(X > 200).

P(X > 200) = 1 - P(X ≤ 210).

Now, P(X ≤ 210) can be calculated using the function poissoncdf(200,210) on the calculator.

As to find the probability of a Poisson Distribution P(X ≤ x), for a mean = λ, we use the calculator function poissoncdf(λ,x).

The value of poissoncdf(200,210) = 0.77271.

Thus, the value of P(X > 210) = 1 - 0.77271 = 0.22729.

Thus, the probability that more than 210 people will pass in front of his store is 0.2272.
