The three angles in the given diagram that are equal to ∠N are; ∠KON ; ∠ION ; ∠IAN

We are given the following about the given triangle;

In triangle NOK, KO = KN

Since KO = KN, it means that triangle NOK is an Isosceles triangle. Thus;

∠KON = ∠N

Since I is the point on KN such that; OI = ON

Thus, this means that triangle OIN is an Isosceles triangle. Thus;

∠ION = ∠N

Since IA = IN

Thus, this means that triangle IAN is an Isosceles triangle. Thus;

∠IAN = ∠N

The standard error of the average sample weight when 15 participants are randomly selected for the sample is 9.05 (rounded to two decimal places).

The standard error of the average sample weight when 15 participants are randomly selected for the sample can be calculated using the formula given below:SE = σ/√nWhere,σ = standard deviation of the populationn = sample sizeSE = standard error of the meansubstituting the given values,SE = 35/√15 = 9.05

Note:When using the given formula, it is important to note that it assumes a normal distribution of sample means. The standard error is used to estimate the true value of the mean from the sample data. The larger the sample size, the smaller the standard error. The smaller the standard error, the more precise the estimate of the true value of the mean.

This question is incomplete. Please find attached to this solved question, the diagram required to solve this question.

Answer:

11 units

Step-by-step explanation:

The shaded portion of the rectangle forms the shape of a trapezium

The area of a trapezium = 1/2(a + b)h

From the diagram, we can see than x = b

a = 7 units

b = 7 units

Area of the trapezium = Area of the shaded portion = 63 square units

A = 1/2(a + b)h

63 = 1/2(7 + b)7

63 = 1/2(49 + 7b)

63 × 2 = 49 + 7b

126 - 49 = 7b

7b = 77

b = 77/7

b = 11 units

Since x = b, x = 11 units

The value of x is 11

Start by calculating the area (A) of the trapezoid using

\(A= 0.5 * (a + b)h\)

Using the parameters from the complete question, we have:

\(63 = 0.5 * (7 + x) * 7\)

Multiply both sides by 2

\(126 = (7 + x) * 7\)

Divide both sides by 7

\(18 = 7 + x\)

Subtract 7 from both sides

\(x = 11\)

Hence, the value of x is 11

Answer:

Let the angle be x.

Its complement is 90°-x° and its supplement is 180°- x.

If 90°-x = (1/2)(180°-x) then 180°- 2x = 180° -x => 180°-180° = 2x-x => x= 0°

Hence the statement is true only for 0°

Answer:

The minimum value is 2.8.  The vertex is (-7, 2.8).

Step-by-step explanation:

Through the x^2 term we identify this as a quadratic function whose graph opens up.  The minimum value of this function occurs at the vertex (h, k).  The x-coordinate of the vertex is

        -b                                                    11.2

x = ---------             which here is x = - ------------ = -7

         2a                                                 2(0.8)

We need to calculate the y value of this function at x = -7.  This y-value will be the desired minimum value of the function.

Substituting -7 for x in the function f(x) = 0.8x^2 + 11.2x + 42 yields

f(-7) = 0.8(-7)^2 + 11.2(-7) + 42 = 2.8

The minimum value is 2.8.  The vertex is (-7, 2.8).

Answer: 9

Step-by-step explanation:

The expression ((t − 9) · (t² − 9) · (t³ − 9) · (t⁴ − 9) · (t⁵ − 9) · (t⁶ − 9) · (t⁷ − 9) can be written in terms of product notation as Π⁷k=1 \((t^k - 9)\).

As per the question, we can write the expression as:

(t − 9) · (t² − 9) · (t³ − 9) · (t⁴ − 9) · (t⁵ − 9) · (t⁶ − 9) · (t⁷ − 9)

Using product notation, we can write this as:

Π⁷k =1 \((t^k - 9)\)

where Π represents the product of terms, k is the index of the product, and the subscript 7 indicates that the product runs from k = 1 to k = 7.

Therefore, the expression ((t − 9) · (t² − 9) · (t³ − 9) · (t⁴ − 9) · (t⁵ − 9) · (t⁶ − 9) · (t⁷ − 9) can be written in terms of product notation as Π⁷k=1 \((t^k - 9)\).

Scenario 2 Magnifi Co. produces a high-end amplifier for musical aficionados. Historically, only 85% of the 200 amplifiers produced per month on average have met the company's demanding standards for quality control. Suppose a random sample of 50 amplifiers is taken from a month's production..

What is the probability that less than 40 of the amplifiers will meet the company's quality standards? b) What is the probability that between 40 and 45 inclusive of the amplifiers will meet the company's quality standards? c) What is the probability that more than 45 of the amplifiers will meet the company's quality standards? a) In order to solve for the probability that less than 40 amplifiers will meet the company's quality standards, we can use the binomial distribution formula: P(X < 40) = Σi=0^39 C(50, i) (0.85)i(1-0.85)50-i

This can be solved using a computer, calculator, or by using a binomial probability table. Using a binomial table, we can find that P(X < 40) = 0.024. Therefore, there is a 0.024 probability that less than 40 amplifiers will meet the company's quality standards. b) To solve for the probability that between 40 and 45 amplifiers inclusive will meet the company's quality standards, we can use the binomial distribution formula again. We need to solve for P(40 ≤ X ≤ 45): P(40 ≤ X ≤ 45) = Σi=40^45 C(50, i) (0.85)i(1-0.85)50-i This can also be solved using a computer, calculator, or binomial table. Using a binomial table, we can find that P(40 ≤ X ≤ 45) = 0.435. Therefore, there is a 0.435 probability that between 40 and 45 amplifiers inclusive will meet the company's quality standards. c) To solve for the probability that more than 45 amplifiers will meet the company's quality standards, we can use the binomial distribution formula one more time. We need to solve for P(X > 45): P(X > 45) = Σi=46^50 C(50, i) (0.85)i(1-0.85)50-i Once again, this can be solved using a computer, calculator, or binomial table. Using a binomial table, we can find that P(X > 45) = 0.056. Therefore, there is a 0.056 probability that more than 45 amplifiers will meet the company's quality standards.Overall, it can be concluded that the probability that less than 40 amplifiers will meet the company's quality standards is low, the probability that between 40 and 45 amplifiers inclusive will meet the company's quality standards is relatively high, and the probability that more than 45 amplifiers will meet the company's quality standards is relatively low.

Answer:

160.125

Step-by-step explanation:

Recall that the length of a curve is \(\displaystyle L=\int^b_a\sqrt{1+\biggr(\frac{dy}{dx}\biggr)^2}dx\), so we'll need to determine \(\frac{dy}{dx}\) using Fundamental Theorem of Calculus Part 1:

\(\displaystyle y=\int^x_1\sqrt{t^3-1}\,dt\\\\\frac{dy}{dx}=\frac{d}{dx}\int^x_1\sqrt{t^3-1}\,dt\\\\\frac{dy}{dx}=\sqrt{x^3-1}\)

Now that we've done so, we can plug \(\frac{dy}{dx}\) into our formula from before and get the length of the parametric curve:

\(\displaystyle L=\int^b_a\sqrt{1+\biggr(\frac{dy}{dx}\biggr)^2}\,dx\\\\L=\int^{11}_1\sqrt{1+\sqrt{x^3-1}^2}\,dx\\\\L=\int^{11}_1\sqrt{1+x^3-1}\,dx\\\\L=\int^{11}_1\sqrt{x^3}\,dx\\\\L=\int^{11}_1x^\frac{3}{2}\,dx\\\\L=\frac{2}{5}x^\frac{5}{2}\biggr|^{11}_1\\\\L=\frac{2}{5}(11)^\frac{5}{2}-\frac{2}{5}(1)^\frac{5}{2}\\\\L\approx160.125\)

Therefore, the length of the curve is about 160.125 units.

As per the double integral, the flux of the vector is 2√11(6z + 1) + 176

What is double integral small definition?

In math, Double integrals are used to find the flux of a vector field through a given surface S and find the normal to the given surface and equations of the surface to find the limits of integration.

And it is calculate by the formula as Flux= ∫∫F⋅ndS

Here we have given that S be the part of the plane 2x + 1y + z = 2 which lies in the first octant, oriented upward.

And we need to find the the flux of the vector field F = 1i + 1j + 3k across the surface S.

As per the formula of flux of vector, it can be written as,

=>Flux =  ∫∫(1i + 1j + 3k) . 2 dS

When we integrate this one the we get,

=> Flux = 2√11(6z + 1) + 176

Here we have the system of equations:

y = 3x^5 - 5x^3 + 2x^2 - 10x + 4

y = 4x^4 + 6x^3 - 11

Notice that both x and y should represent the same thing in both equations, then we could write:

3x^5 - 5x^3 + 2x^2 - 10x + 4 = y = 4x^4 + 6x^3 - 11
