Customers arrive at the CVS Pharmacy drive-thru at an average rate of 5 per hour. What is the probability that more than 6 customers will arrive at the drive-thru during a randomly chosen hour? 0.146

The average cost function is C(x) = 5000x + 20,000/x, where x is the number of machines used in the production. The critical value is C(x) = 20,000 and it happens when x = 2.

If we have a function f(x), the critical point happens when its first derivative is equal to zero.

             f '(x) = 0

In the given problem, the function is:

C(x) = 5000x + 20,000/x

Take the derivative:

C '(x) = 5000 - 20,000/x² = 0

5000 x² = 20,000

x² = 4

x = ±2

Since x is within the interval: 0<x<∞, the solution is x = 2

Substitute x = 2 into the function:

C(2) = 5000 (2) + 20000/2

C(2) = 10000 + 10000 = 20,000

Hence, the critical value is C(x) = 20,000 and it happens when x = 2.

Answer:

y = -2x + 1

Step-by-step explanation:

The equation is in standard form, first, we need to convert it to slope-intercept form.

5 = -10x - 5y

5 + 10x = -5y

Divide both sides by -5 to isolate y variable.

y = -2x - 1

If the line is parallel, the slope remains the same.

To find the y-intercept, you need to plug the values of x and y into the equation, which is y = 2x + b

5 = -2(-2) + b

5 = 4 + b

1 = b

The equation is -2x + 1

In the triangle , the value of x is 57.

What is triangle?

A triangle is a form of polygon with three sides; the intersection of the two longest sides is known as the triangle's vertex. There is an angle created between two sides. One of the crucial elements of geometry is this.

Certain fundamental ideas, including the Pythagorean theorem and trigonometry, rely on the characteristics of triangles. The angles and sides of a triangle determine its kind.

Here in the given triangle , SD=99 , SF=44 , RF = 76 and FE = 76+3x

RE = FE - RF

=> RE = 76+3x-76 = 3x

Now using triangle proportionality theorem then,

=> \(\frac{SF}{SD}=\frac{RF}{RE}\)

=> \(\frac{44}{99}=\frac{76}{3x}\)

=> 3x = \(\frac{76\times99}{44}\) = 171

=> x = 171/3 = 57

Hence the value of x is 57.

To find the perimeter of triangle formed by the tangents to the circles, find radii of circles and side lengths of triangle. The perimeter of triangle formed by the tangents to the circles is 12 times the radius of each circle.

Let's denote the radius of each circle as r. Since the circles are externally tangent to each other, the distance between their centers is equal to the sum of their radii, which is 2r.

When a triangle is formed by connecting the points of tangency on each circle, it creates three isosceles triangles. Each of these isosceles triangles has two congruent sides, which are the radii of the circles.By drawing the triangle, we can observe that the base of each isosceles triangle is equal to 2r, which corresponds to the diameter of one of the circles. The height of each isosceles triangle is equal to r, which is the radius of the circle.

Therefore, each side of the triangle formed by the tangents has a length of 4r.Since the triangle has three equal sides, its perimeter is given by 3 times the length of one side, which is 3 * 4r = 12r.The perimeter of the triangle formed by the tangents to the circles is 12 times the radius of each circle.

Answer: Three sides of a right triangle are the lengths of its legs and the length of its hypotenuse.

To know that three given sides will create a right triangle, we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs. Symbolically, if a, b, and c are the lengths of the sides of a right triangle, with c being the hypotenuse, then:

c^2 = a^2 + b^2

Therefore, if we are given the lengths of three sides, we can square the lengths of the legs, add them together, and then take the square root to find the length of the hypotenuse. We can then compare the squared length of the hypotenuse to the sum of the squares of the legs. If they are equal, the three sides form a right triangle. If the squared length of the hypotenuse is greater than the sum of the squares of the legs, the three sides form an obtuse triangle. If the squared length of the hypotenuse is less than the sum of the squares of the legs, the three sides form an acute triangle.

The optimal point values for x1, x2, λ, and μ (Lagrange multipliers) in the given problem are:

x1 = 1

x2 = 1

λ = -4

μ = 2

To solve the optimization problem using the Lagrange multipliers technique, we first construct the Lagrangian function L(x1, x2, λ) by incorporating the equality constraint:

L(x1, x2, λ) = f(x1, x2) - λ(g(x1, x2))

Where f(x1, x2) is the objective function, g(x1, x2) is the equality constraint, and λ is the Lagrange multiplier.

In this case, the objective function is f(x1, x2) = 2x1^2 - 2x1x2 + 2x2 - 6x1 + 6, and the equality constraint is g(x1, x2) = x1 + x2 - 2.

The Lagrangian function becomes:

L(x1, x2, λ) = 2x1^2 - 2x1x2 + 2x2 - 6x1 + 6 - λ(x1 + x2 - 2)

To find the optimal values, we need to find the critical points by taking partial derivatives of L with respect to x1, x2, and λ and setting them equal to zero. Solving these equations simultaneously, we get:

∂L/∂x1 = 4x1 - 2x2 - 6 - λ = 0

∂L/∂x2 = -2x1 + 2 + λ = 0

∂L/∂λ = -(x1 + x2 - 2) = 0

Solving these equations, we find x1 = 1, x2 = 1, and λ = -4. Substituting these values into the equality constraint, we can solve for μ:

x1 + x2 - 2 = 1 + 1 - 2 = 0

Therefore, μ = 2.

The optimal point values for the variables in the optimization problem are x1 = 1, x2 = 1, λ = -4, and μ = 2. The Lagrange multipliers λ and μ represent the rates of change of the objective function and the equality constraint, respectively, with respect to the variables. They provide insights into the sensitivity of the objective function to changes in the constraints and can indicate the impact of relaxing or tightening the constraints on the optimal solution. In this case, the Lagrange multiplier λ of -4 indicates that a small increase in the equality constraint (x1 + x2 - 2) would result in a decrease in the objective function value. The Lagrange multiplier μ of 2 indicates the shadow price or the marginal cost of satisfying the equality constraint.

the denominators need to be the same so if we multiply the first fraction by 6 and the second by 5, our new equation is

24/30 - 5/30

24-5=19

19/30 is your answer

Answer & Step-by-step explanation:

\(\frac{4}{5}-\frac{1}{6}\)

When you need to subtract fractions, the denominators (bottom) need to be the same. For this, you have to multiply both fractions until the bottom numbers are the same:

Find the lowest common multiple of the denominators:

\(5,10,15,20,25,30\\6,12,18,24,30\)

The LCM of 5 and 6 is 30. Now you have to multiply the top and bottom of the fractions until you get a denominator of 30*:

\(\frac{4(6)}{5(6)}=\frac{24}{30}\\\\\frac{1(5)}{6(5)}=\frac{5}{30}\)

So,

\(\frac{24}{30} -\frac{5}{30}\)

When you subtract fractions, you only change the numerators (top). The denominator will stay the same:

\(\frac{24}{30} -\frac{5}{30}=\frac{19}{30}\)

Since the fraction can't be further simplified,  \(\frac{4}{5}-\frac{1}{6}=\frac{19}{30}\)

A 95% confidence interval for the estimated proportion of Canadians who refused the H1N1 vaccination can be calculated as follows:

Let p be the true proportion of Canadians who refused the vaccination.

The sample proportion is estimated by:

p_hat = 700 / 1000 = 0.7

The standard error of the sample proportion is:

SE = sqrt(p_hat * (1 - p_hat) / 1000) = sqrt(0.7 * 0.3 / 1000) = 0.0247

Using a normal approximation and a z-score of 1.96 (corresponding to a 95% confidence level), the confidence interval can be calculated as:

p_hat +/- z * SE = 0.7 +/- 1.96 * 0.0247 = [0.6511, 0.7489]

The equation of the tangent line to f(x) at x = 7 is:y = -1/49 x + 50/343. So, the tangent line is y = -1/49 x + 50/343.

Given f(x) = x⁻¹ and f'(x) = -x⁻² and x = 7, we need to find the equation of the tangent line to f(x) at x = 7.Let the equation of the tangent line be y = mx + c, where m is the slope of the tangent line and c is the y-intercept of the tangent line.Then the slope of the tangent line at x = 7 is given by f'(7) = -7⁻²= -1/49. Therefore, the slope of the tangent line is m = -1/49.Since the point (7, 1/7) lies on the curve f(x) = x⁻¹, it lies on the tangent line as well. Hence we have:y = mx + cSubstituting x = 7, y = 1/7 and m = -1/49, we get:1/7 = -1/49(7) + c. On solving, we get c = 50/343. Therefore, the equation of the tangent line to f(x) at x = 7 is:y = -1/49 x + 50/343So, the tangent line is y = -1/49 x + 50/343.

Tangent and Bernoulli numbers are related to Motzkin and Catalan numbers through the concept of numerical triangles. Numerical triangles are a visual representation of the coefficients in a power series expansion.

Motzkin numbers, named after Theodore Motzkin, count the number of different paths in a 2D plane that start at the origin, move only upwards or to the right, and never go below the x-axis. These numbers have applications in various mathematical fields, including combinatorics and computer science.

Catalan numbers, named after Eugène Charles Catalan, also count certain types of paths in a 2D plane. However, Catalan numbers count the number of paths that start at the origin, move only upwards or to the right, and touch the diagonal line y = x exactly n times. These numbers have connections to many areas of mathematics, such as combinatorics, graph theory, and algebra.

The relationship between tangent and Bernoulli numbers comes into play when looking at the generating functions of Motzkin and Catalan numbers. The generating function for Motzkin numbers involves the tangent function, while the generating function for Catalan numbers involves the Bernoulli numbers.

The connection between these generating functions and numerical triangles is based on the coefficients that appear in the power series expansions of these functions. The coefficients in the expansions can be represented as numbers in a triangular array, forming a numerical triangle.

These connections provide insights into the properties and applications of Motzkin and Catalan numbers in various mathematical contexts.
