The sample distribution would have a mean of 67

The sample distribution's standard deviation would equal its standard error = 1

μ = 67

σ = 6

n = 36

Approximately normal sampling distribution for the sample mean with mean and standard deviation = σ / √n

The sample distribution's mean would be, μ = 67

The sample distribution's standard error (standard deviation) would be =  σ / √n = 6 / √36 = 1

According to the central limit theorem, if the population distribution is normal, the sampling distribution of the sample mean will be roughly normal for any sample size, or if the sample size is large enough to be n>30, the sampling distribution will be roughly normal with mean and standard deviation for any population distribution =  σ / √n

Therefore, The sample distribution's mean would be = 67

and the sample distribution's standard error (standard deviation) would be = 1

bro you need to add the rest of the question

The absolute maximum value of f(x) on the interval [-3,1] is approximately 0.933, which occurs at x = 1.

The function f(x) = ln(x^2 + 5x + 10) is continuous on the closed and bounded interval [-3,1], therefore by the Extreme Value Theorem, it must have an absolute maximum and an absolute minimum on that interval.

To find the critical points, we need to find where the derivative of the function is zero or undefined. We have:

f(x) = ln(x^2 + 5x + 10)

f'(x) = (2x + 5)/(x^2 + 5x + 10)

The derivative is undefined when the denominator is zero, that is, when x^2 + 5x + 10 = 0. This quadratic equation has no real roots, so there are no values of x where the derivative is undefined.

The derivative is zero when the numerator is zero, that is, when 2x + 5 = 0. This gives x = -5/2.

Now we need to check the values of the function at the critical points and at the endpoints of the interval:

f(-3) ≈ -0.078

f(-5/2) ≈ -0.688

f(1) ≈ 0.933

Therefore, the absolute minimum value of f(x) on the interval [-3,1] is approximately -0.688, which occurs at x = -5/2.

The absolute maximum value of f(x) on the interval [-3,1] is approximately 0.933, which occurs at x = 1.

The difference between these two amounts is $619.68

The monthly payment for a loan can be calculated using the formula:

monthly payment = \(\frac{(P * r * (1 + r)^n) }{((1 + r)^n - 1)}\)

where P is the principal (the amount borrowed), r is the monthly interest rate, and n is the total number of months in the loan term.

For Miles' loan,

P = $5,000,

r = 0.0775/12,

and n = 4 * 12 = 48.

Plugging these values into the formula, we get:

monthly payment = \(\frac{(5000 * 0.0775/12 * (1 + 0.0775/12)^{48})}{ ((1 + 0.0775/12)^{48} - 1) }\)

= $123.37

For Nick's loan,

P = $5,000,

r = 0.1310/12,

and n = 4 * 12 = 48.

Plugging these values into the formula, we get:

monthly payment =\(\frac{ (5000 * 0.1310/12 * (1 + 0.1310/12)^{48})}{((1 + 0.1310/12)^{48} - 1) }\)

= $143.34

To find out how much more Nick will have paid than Miles over the four-year period, we can subtract Miles' total payments from Nick's total payments.

Miles will make 48 payments of $123.37, for a total of:

$123.37 * 48 = $5,920.76

Nick will make 48 payments of $143.34, for a total of:

$143.34 * 48 = $6,540.32

The difference between these two amounts is:

\(6,540.32 - 5,920.76 = 619.56\)

Rounding this to the nearest cent, we get $619.68. Therefore, the answer is (a) $619.68.

To solve this problem, we can use the method of Lagrange multipliers. This method allows us to find the maximum or minimum of a function subject to constraints.

In this case, the function we want to maximize is Z = 2x + 3y and the constraints are x = 24, y = 25, and 3x + 2y = 52.We begin by setting up the Lagrangian function, which is given by:L(x, y, λ) = Z - λ(3x + 2y - 52)where λ is the Lagrange multiplier. We then take the partial derivatives of the Lagrangian with respect to x, y, and λ and set them equal to zero.∂L/∂x = 2 - 3λ = 0∂L/∂y = 3 - 2λ = 0∂L/∂λ = 3x + 2y - 52 = 0Solving for λ, we get λ = 2/3 and λ = 3/2. However, only one of these values satisfies all three equations. Substituting λ = 2/3 into the first two equations gives x = 20 and y = 22. Substituting these values into the third equation confirms that they satisfy all three equations. Therefore, the maximum value of Z subject to the given constraints is Z = 2x + 3y = 2(20) + 3(22) = 84.

The maximum value of Z = 2x + 3y, subject to the conditions x ≤ 24, y ≤ 25, and 3x + 2y = 52, is 96.

To maximize the function Z = 2x + 3y, subject to the conditions x ≤ 24, y ≤ 25, and 3x + 2y = 52, we will use the method of linear programming.

Let us first graph the equation 3x + 2y = 52.

The intercepts of the equation 3x + 2y = 52 are (0, 26) and (17.33, 0).

Since the feasible region is restricted by x ≤ 24 and y ≤ 25, we get the following graph.

We observe that the feasible region is bounded and consists of four vertices:

A(0, 26), B(8, 20), C(16, 13), and D(24, 0).

Next, we construct a table of values of Z = 2x + 3y for the vertices A, B, C, and D.

We observe that the maximum value of Z is 96, which occurs at the vertex B(8, 20).

Therefore, the maximum value of Z = 2x + 3y, subject to the conditions x ≤ 24, y ≤ 25, and 3x + 2y = 52, is 96.

The measure of the arc of the circular basin of the fountain that will be in the photograph is; 111°

Now, To answer this question, we need to understand the angle of intersecting secant theorem which state that;

If two lines intersect outside a circle, then the measure of the angle formed by the two lines is half of the positive difference of the measures of the intercepted arcs.

Thus;

θ = 1/2 (x₂ - x₁)

Where:

x₂ is large angle

x₁ is small angle

θ is measure of the Angle formed by the two lines

Now, we are given θ = 69°

Now the measure of the arc of the circular basin will be the smaller angle x₁.

However, the sum of the large and small angle is 360° and so large angle is 360 - x₁.

Thus;

69 = 1/2(360 - x - x)

2 × 69 = 360 - 2x

138 = 360 - 2x

360 - 138 = 2x

2x = 222

x = 222/2

x = 111°

Thus, The measure of the arc of the circular basin of the fountain that will be in the photograph is; 111°

Answer:

180

Step-by-step explanation:

A 3-digit number cannot start with 0, so the leftmost digit is a choice of 6 digits out of the 7. The middle digit can be chosen from all 7 digits minus the one already used, so there are 6 choices. The right digit can be chosen from 5.

6 × 6 × 5 = .180

The number of three-digit numbers that can be formed from the digits 0, 1, 2, 3, 4, 5, and 6 is 180.

This can be calculated by finding the number of element availabe at first place which is 6 excluding 0 than for second position 6 as first number is excluded and 0 is added and for the last positon the number of possibe combination is 5 as 2 digits are already used.

The final answer is 6*6*5 = 180

Tue area of the new figure is 28ft

Step-by-step explanation:

Each side 20/4=5

The length 5+2=7

The width 5-1=4

The area 7x4=28

The relationship between variable F and x is 2x + 12000000/x

Let y represent the length (in feet) of a side perpendicular to the dividing fence, and let x represent the length (in feet) of a side parallel to the dividing fence.

Let F represent the length of fencing in feet.

Area of fencing = 6000000 ft²

Area of fencing = x * (y + y) = x * 2y

Area of fencing = 2xy

6000000=2xy

xy = 3000000

y = 3000000/x

The perimeter is:

F = x + y + y + x + y + y

F = 2x + 4y

F = 2x + 4(3000000/x)

F = 2x + 12000000/x

Answer:

Step-by-step explanation:

Yes, the irrational number stays irrational.

Make the assumption that this statement is false and that a rational and an irrational can produce a rational. x is irrational. Assume that a, b, c, and d are all integers.  If you like, they can be relatively prime to each other.

a/b + x = c/d                   Subtract a/b from both sides.

x = c/d - a/b                    Now put the 2 fractions over a common denominator.

x = (c*b - d*a)/(b*d)         Investigate what you have.

b*d are two integers multiplied together. multiplication of integers is closed (the answer will be an integer).

cb and da are also integers. subtracted integers are also closed under subtraction.

But

Here's the kicker. An irrational number is one that cannot be expressed as a fraction. Sqrt(2) for example cannot be shown to be rational. There is no fraction that equals sqrt(2)

So our proof is "bogus." It cannot work. An irrational number excludes the possibility of being able to be represented by a fraction by definition.
