The chi-square statistic is used to determine whether there are differences between two nominally scaled variables. Chi-Square is a statistical test used to compare two nominal variables to determine whether they differ.

The Chi-Square test is used to test for differences between two groups. When you want to compare groups or examine the relationship between two variables, this test is useful. The chi-square test is a method of statistical inference that can be used to compare observed frequencies with expected frequencies, allowing us to determine whether there is a meaningful difference between them. When the p-value obtained from a chi-square test is less than 0.05, it is generally considered statistically significant.

It is proven that the pair of opposite sides are equal and parallel and as such the quadrilateral ABCD is a parallelogram.

Given: A quadrilateral ABCD in a graph.

To Prove: ABCD is a parallelogram.

A diagonal AC will divide it into 2 triangles ACD and ACB .

Proof:

From the figure, we see that the sides AB and CD are 4 cm each.

Thus: AB = DC        ...(i)

The angles <BAC and <ACD are alternate interior angles since  AB=CD and AB || CD. Thus:

<BAC = <ACD         …(ii)

It can also be deduced that the triangles ACD and ACB have a common base AC.

Thus, by reflexive property of congruence:

AC = AC      …(iii)

From equations i, ii, and iii, ΔACB ≅ ΔACD (Congruent) by SAS congruence.

Thus, the pair of opposite sides AD and BC are equal due to their congruence. Hence, if the BD diagonal is constructed, it can be proven that the triangles BDA and BDC in a similar way.

Hence it is proven that the pair of opposite sides are equal and parallel. (Sides cannot be congruent, only triangles can). So, the quadrilateral ABCD is a parallelogram.

The statements that are true are the volume of the box is v = lwh = 864 in³ and the volume can be expressed in an equation as v = 6x² = 864in³

The volume of a square box is equal to the cube of the length of the side of the square box. The formula for the volume is V = l³, where "l" is the length of the side of the square box.

In the given problem, the volume of the box is 864 cubic inches.

However, we have to remember that the box isn't a square, but rather the base has a square shape.

The volume of the figure is

v = l * w * h

If we divide the volume by the height, we will have the area of the figure

Area = volume / height

Area = 864 / 6

Area = 144 square inches

Since the base has a square shape;

A = l²

144 = l²

l = √144

The percent error of Diane's estimated area measurement is 9%.

To find the percent error, we first calculate the actual area of the rectangular field:

Next, we calculate the estimated area based on Diane's measurements:

The absolute error is the difference between the actual and estimated areas:

The percent error is the absolute error divided by the actual area, multiplied by 100%:

Percent error = (Absolute error / Actual area) × 100% = (276 / 2,976) × 100% = 0.092 × 100% = 9%

Therefore, the percent error of Diane's estimated area measurement is 9% to the nearest whole percent.

Component 3 must be started on day 197 to meet the delivery date of day 200.

To illustrate the backward schedule, we need to start from the delivery date (day 200) and work our way backward, taking into account the lead times and dependencies of each operation.

(a) Backward schedule:

Operation    |  Work Center  |  Time (hours)  |  Start Day

--------------------------------------------------------

Final Assembly |   Work Center 1  |        1       |     200

Sub-assembly 1 |   Work Center 2  |        2       |     199

Component 4     |   Work Center 3  |        3       |     197

Component 2     |   Work Center 4  |        4       |     196

Component 3     |   Work Center 5  |        3       |     ????

(b) To identify when component 3 must be started to meet the delivery date, we need to consider its dependencies and lead times.

From the backward schedule, we see that component 3 is required for sub-assembly 1, which is scheduled to start on day 199. The time required for sub-assembly 1 is 2 hours, which means it should be completed by the end of day 199.

Since component 3 is needed for sub-assembly 1, we can conclude that component 3 must be started at least 2 hours before the start of sub-assembly 1. Therefore, component 3 should be started on day 199 - 2 = 197 to ensure it is completed and ready for sub-assembly 1.

Hence, component 3 must be started on day 197 to meet the delivery date of day 200.

Answer:

60%

Step-by-step explanation:

Answer:

60% is the correct answer.

The recursive formula for the predicted number of speeding tickets issued each year in Middletown, starting from 2012 with an initial count of 190 tickets and growing by 10% each year, can be written as follows: N(year) = 1.1 * N(year - 1).

The recursive formula for the predicted number of speeding tickets each year is based on the assumption of exponential growth, where the number of tickets issued increases by 10% each year.

Let's denote N(year) as the predicted number of speeding tickets during a particular year. According to the given information, in the year 2012, Middletown issued 190 speeding tickets, which serves as our initial count or base case.

To calculate the number of tickets in subsequent years, we multiply the previous year's count by 1.1, representing a 10% increase. Therefore, the recursive formula for the predicted number of speeding tickets is:

N(year) = 1.1 * N(year - 1).

Using this formula, we can determine the predicted number of speeding tickets for any given year by recursively applying the growth rate of 10% to the previous year's count.

The factors of  polynomial expression x^4 + x^2 − 20 is \((x - \sqrt{5})(x + \sqrt{5})(x - i \sqrt{5})(x + i \sqrt{5})$\).

We are given that;

The polynomial expression =\(x^4 + x^2 − 20.\)

Now,

To factor a polynomial expression, we need to find the common factors of each term and then use the distributive property to write the expression as a product of two or more factors.

For example,\(x^4 + x^2 − 20\) can be written as:

\($x^4 + x^2 - 20 = x^2(x^2 + 1) - 20$\)

We can use the difference of squares formula to factor x^2 + 1 and 20:

\($x^2 + 1 = (x + i)(x - i)20 = (2 \sqrt{5})(2 \sqrt{5})\)

where i is the imaginary unit such that i^2 = -1. Now, we can write the expression as:

\($x^4 + x^2 - 20 = x^2(x + i)(x - i) - (2 \sqrt{5})(2 \sqrt{5})$\)

We can use the difference of squares formula again to factor the whole expression:

\($x^4 + x^2 - 20 = (x^2 - 2 \sqrt{5})(x^2 + 2 \sqrt{5})$\)

we can still factor each factor further into prime factors. We have:

\(x^2 - 2 \sqrt{5} = (x - \sqrt{5})(x + \sqrt{5})$\\$x^2 + 2 \sqrt{5} = (x - i \sqrt{5})(x + i \sqrt{5})\)

Therefore, by factorization answer will be \((x - \sqrt{5})(x + \sqrt{5})(x - i \sqrt{5})(x + i \sqrt{5})$\)

Multiply ONLY the numerator with the whole number to get the answer:

Simplify:

The function composition exists an operation " ∘ " that brings two functions f and g, and has a function h = g ∘ f such that h(x) = g(f(x)).

Let the functions be f(x) = 4x² + 1 and g(x) = x² - 3

The correct answer is (f o g)(x) = 4x⁴ - 96x + 37 and

(g o f)(x) = 16x⁴ + 8x² - 2.

The function composition exists an operation " ∘ " that brings two functions f and g, and has a function h = g ∘ f such that h(x) = g(f(x)). In this operation, the function g exists used for the outcome of applying the function f to x.

Given:

f(x) = 4x² + 1 and g(x) = x² - 3

a) (f o g)(x) = f[g(x)]

f[g(x)] = 4(x² - 3)² + 1

substitute the value of g(x) in the above equation, and we get

    = 4(x⁴ - 24x + 9) + 1

simplifying the above equation

    = 4x⁴ - 96x + 36 + 1

    = 4x⁴ - 96x + 37

(f o g)(x) = 4x⁴ - 96x + 37

b) (g o f)(x) = g[f(x)]

substitute the value of g(x) in the above equation, and we get

g[f(x)] = (4x² + 1)²- 3

      = 16x⁴ + 8x² + 1 - 3

simplifying the above equation

      = 16x⁴ + 8x² - 2

(g o f)(x) = 16x⁴ + 8x² - 2.

Therefore, the correct answer is (f o g)(x) = 4x⁴ - 96x + 37 and

(g o f)(x) = 16x⁴ + 8x² - 2.

Answer:

There are 68,640 different ways the runners can finish first, second, and third in the race.

Concept of Permutations

The number of different ways the runners can finish first, second, and third in a race can be calculated using the concept of permutations.

Brief Overview

Since there are 42 runners competing for the top three positions, we have 42 choices for the first-place finisher. Once the first-place finisher is determined, there are 41 remaining runners to choose from for the second-place finisher. Similarly, once the first two positions are determined, there are 40 runners left to choose from for the third-place finisher.

Calculations

To calculate the total number of different ways, we multiply the number of choices for each position:

42 choices for the first-place finisher × 41 choices for the second-place finisher × 40 choices for the third-place finisher = 68,640 different ways.

Concluding Sentence

Therefore, there are 68,640 different ways the runners can finish first, second, and third in the race.

The probability that the salesperson will make exactly two sales in a day is 0.1489, the probability that the salesperson will make at least two sales in a day is 0.1451, and the expected number of sales per day is 0.8.

Let X be the number of sales made per day by the salesperson.

Then X follows a binomial distribution with parameters n = 8 and p = 0.10.a. To find the probability that the salesperson will make exactly two sales in a day, we need to find P(X = 2).

P(X = 2) = nCx * p^x * q^(n-x) = 8C2 * (0.10)^2 * (0.90)^6 = 28 * 0.01 * 0.5314 = 0.1489

Therefore, the probability that the salesperson will make exactly two sales in a day is 0.1489.

b. To find the probability that the salesperson will make at least two sales in a day, we need to find P(X ≥ 2).

P(X ≥ 2) = 1 - P(X < 2) = 1 - [P(X = 0) + P(X = 1)] = 1 - [(8C0 * (0.10)^0 * (0.90)^8) + (8C1 * (0.10)^1 * (0.90)^7)] = 1 - [1 * 0.90^8 + 8 * 0.10 * 0.90^7] = 0.1451

Therefore, the probability that the salesperson will make at least two sales in a day is 0.1451.

c. Expected number of sales per day = E(X) = n * p = 8 * 0.10 = 0.8

Therefore, the expected number of sales per day is 0.8.
