Answer:

C=0.15y+7.89

Step-by-step explanation:

The linear equation represents the cost C of a movie ticket y is C=0.15y+7.89. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."

A linear equation is an algebraic equation of the form y=mx + b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."

We define a linear equation. Equations of degree 1 are linear equations. It is the straight line's equation. A linear equation with parameters a and b equal to zero has the conventional form ax+by+c = 0.

When two linear expressions are equal, there is a linear equation in one variable. Or, to put it another way, a graph would be one method of solving this equation.

Given ,

Average price of movie ticket =$7.89

Increased average tickets =$0.15

So Simplifying the equation is

C=0.15y+7.89

Therefore The linear equation represents the cost C of a movie ticket y is C=0.15y+7.89.

Answer:

Step-by-step explanation:

Given the expression;

secθ − tan θ = cosθ

We are to find the solution in the interval [0, 2π).This is as shown;

From trigonometry identity;

secθ = 1/cosθ

tanθ = sinθ/cosθ

Substitute into the formula;

secθ − tan θ = cosθ

1/cosθ-sinθ/cosθ = cosθ

Multiply through by cosθ

1 - sinθ = cos²θ

1-sinθ = (1-sin²θ)

1-sin²θ-1+sinθ =0

-sin²θ+sinθ = 0

sin²θ = sinθ

sinθ = 1

θ = arcsin 1

θ = 90

θ = π/2

Hence the solution is π/2

The equation is an illustration of trigonometry ratios and identities

The solution in the interval  [0, 2π) is [tex]\mathbf{\theta = \frac{\pi}{2}}[/tex]

The equation is given as:

[tex]\mathbf{sec\theta - tan \theta = cos\theta}[/tex]

In trigonometry identity, we have:

[tex]\mathbf{sec\theta = \frac{1}{cos\theta}}[/tex]

and

[tex]\mathbf{tan\theta = \frac{sin\theta}{cosθ}}[/tex]

So the equation becomes

[tex]\mathbf{\frac{1}{cos\theta} -\frac{sin\theta}{cos\theta} = cos\theta}[/tex]

Multiply through by cosθ

[tex]\mathbf{1 - sin\theta = cos\²\theta}[/tex]

In trigonometry,

[tex]\mathbf{cos\²\theta = 1 - sin^2\theta }[/tex]

So, we have:

[tex]\mathbf{1-sin\theta = 1-sin\²\theta}[/tex]

Subtract 1 from both sides

[tex]\mathbf{sin\theta = sin\²\theta}[/tex]

Divide both sides by [tex]\mathbf{sin\theta}[/tex]

[tex]\mathbf{1 = sin\theta}[/tex]

Rewrite as:

[tex]\mathbf{sin\theta = 1}[/tex]

Take arc sin of both sides

[tex]\mathbf{\theta = sin^{-1}(1)}[/tex]

This gives

[tex]\mathbf{\theta = \frac{\pi}{2}}[/tex]

Based on the sample, can it be concluded that μ is not different from 45 centimeters

Step-by-step explanation:

Step( i ):-

Heights were measured for a random sample of 10 plants

Size of the sample 'n' = 10

Mean of the sample (x⁻ ) = 46 centimeters

Standard deviation of the sample (s) = 7 centimeters

Can I get brainiest now?

Answer:

100 inches

Step-by-step explanation:

Given

20 inch ≈ 0.5 m

Required

Determine the equivalent of 2.5m in inches

The question illustrated conversion between units of same measurements.

And we have that:.

20 in ≈ 0.5 m

Which can be rewritten as:

0.5 m ≈ 20 in

To solve further, we multiply both sides by 5

0.5 m * 5 = 20 in * 5

2.5 m ≈ 100 in

Hence, we can conclude that the 2.5m rope is approximately 100 inches long

The 2.5m rope is approximately 100 inches long

We have to given that,

20 inch ≈ 0.5 m

And, To Determine the equivalent of 2.5m in inches.

Since, It is illustrated conversion between units of same measurements.

And we have that;

20 in ≈ 0.5 m

Which can be rewritten as:

0.5 m ≈ 20 in

we multiply both sides by 5

0.5 m x 5 = 20 in x 5

2.5 m ≈ 100 in

Hence, we can conclude that the 2.5m rope is approximately 100 inches long.

84.24 - 6.24 = p

Step-by-step explanation:

Answer:

0.12995

0.47508

0.0841

0.738

Step-by-step explanation:

Given that:

Percentage of STEM (p) = 27% = 0.27

Sample size (n) = 47

Using Normal approximation :

Mean (m) = n*p = 47 * 0.27 = 12.69

Standard deviation (s) = √(n*p*q)

q = 1 - p = 1 - 0.27 = 0.73

Standard deviation (s) = √(47*0.27*0.73) = 3.04

a. Exactly 13 of them major in STEM.

P(12.5 < x < 13.5)

USing the z formula :

(x - m) / s

(12.5 - 12.69) / 3.04 < x (13.5 - 12.69) / 3.04

-0.0625 < z < 0.2664

Using the z probability calculator:

P(Z < - 0.0625) = 0.47508

P(Z < 0.2664) = 0.60503

0.60503 - 0.47508

= 0.12995

b. At most 12 of them major in STEM.

P(X ≤ 12.5)

Zscore = (x - m) / s

Zscore = (12.5 - 12.69) / 3.04

Zscore = −0.0625

P(Z ≤ - 0.0625) = 0.47508

c. At least 9 of them major in STEM.

P(X ≥ 8.5)

Zscore = (x - m) / s

Zscore = (8.5 - 12.69) / 3.04

Zscore = −1.378

P(Z ≤ - 1.378) = 0.0841

d. Between 8 and 15 (including 8 and 15) of them major in STEM.

(8.5 - 12.69) / 3.04 < x (15.5 - 12.69) / 3.04

-1.378 ≤ z ≤ 0.924

Using the z probability calculator:

P(Z ≤ 0.924) = 0.82226

P(Z ≤ - 1.378) = 0.084102

0.82226 - 0.084102

= 0.738

Step-by-step explanation:

Answer:

The answer is "50".

Step-by-step explanation:

Let,

[tex]\to p(200) = 400[/tex]

If we assume the $20 reduction would raise the number of items sold to $40 so the increment is (x - 200) if x is the number of units sold.

[tex]\to (\frac{1}{40}) \times 20 = 0.5[/tex]

[tex]\to D(x) = 400 - 0.5 \times ( x - 200 ) \\\\ \ and \\ \to R(x) = x \times (D(x) \\\\[/tex]

            [tex]= x \times [ 400 - 0.5\times ( x - 200 )]\\\\ = x\times[400 - 0.5x - 100]\\\\= x\times [300 - 0.5 x]\\\\= 300x - 0.5 x^2[/tex]

[tex]R(x)= 300x- \frac{1}{2} x^2\\\\R'(x)=300-x\\[/tex]

if R'(x)=0

x=300

if  0 < x  < 300  and R(x) > 0 then R(x) for maximum x is = 300

[tex]D(300) = 400 - 0.5\times ( x - 200 )\\\\[/tex]

            [tex]= 400 - 0.5\times ( 300- 200 )\\\\ = 400 - 150+ 100\\\\ = 500 - 150 \\\\=350[/tex]

The rebate must be  : 400 - 350  = 50
